Odd Lots - CoreWeave's CSO on the Business of Building AI Datacenters

Episode Date: June 21, 2024

Everyone knows that the AI boom is built upon the voracious consumption of chips (largely sold by Nvidia) and electricity. And while the legacy cloud operators, like Amazon or Microsoft, are in this s...pace, the nature of the computing shift is opening up new space for new players in the market. One of the hottest companies is CoreWeave, a company backed in part by Nvidia, which has grown its datacenter business massively. So how does their business actually work? How do they get energy? Where do they locate operations? How are they financed? What's the difference between a cloud AI and a legacy cloud? On this episode, we speak with CoreWeave's Chief Strategy Officer Brian Venturo about what it takes to build out operations at this scale.See omnystudio.com/listener for privacy information.

Starting point is 00:01:27 Hello and welcome to another episode of the Odd Lots podcast. I'm Joe Wisenthall. And I'm Tracy Allaway. Tracy, you know, we've done tons, of course, on like electricity and AI and data centers and all that stuff. But we've never actually done like a, well, we've never talked to someone who is building data centers. Putting it all together, you mean? Yeah, putting it all together. Like what, you know, just a bunch of, you know, I've had consultants.
Starting point is 00:01:55 We've talked to energy people. But like, how does this business of essentially, I guess, building a building, putting a bunch of chips in there, getting the electricity, and then in theory selling all of that at a markup, like how does it actually work? You know what I was reading recently? This is kind of a tangent, but not really, because we're talking about the physical and financial process of building these things. things. But I saw, this is online, there is a guide to the like physical planning around an IBM
Starting point is 00:02:27 system 360 from like 1963 or something. And it's 213 pages long. Have you read it yet? I did flip through it. There's like there's guidance on minimizing vibrations. Obviously like temperature and humidity and stuff like that. I did not read the full 200 pages. But I'm kind of thinking like if this is all the thinking that had to go into like one computer, albeit a supercomputer in the 1960s, but like a pretty basic machine when we look back on it now, how much planning and thinking has to go into building, like these huge cloud servers and all their associated infrastructure, both physical and software as well. No, totally.
Starting point is 00:03:12 And you know, one of the ways that we've touched on this subject a little bit is in our conversations with Steve Eisman, who's been investing, at least as far as we know, in a lot of these, like, industrial HVAC companies and electricity gear companies and stuff like that. So, like, companies that have actually been around for a really long time, sort of standard cyclical businesses, and then they've, like, caught the secular tailwind because with this boom in AI data center construction, suddenly there's this sort of continuous bid for all their gear services. I'm going to start an anti-vibration floor maker or something. Do you think that's a viable business? Does anyone care about vibrations anymore? I am certain that in various high-tech
Starting point is 00:03:55 environments, you do not want to have vibrations. You know, you have like valuable chips. You don't want them to be like degrading. Because people are walking around. Yeah, or just, you know, all the machine and all your air conditioners and cooling equipment and all that stuff, you can't be having that stuff degrade. Well, the other interesting thing that's happening in the space now. So in a addition to the physical challenge of building a bunch of this stuff. There's also the financial aspect of it. And I guess as AI becomes more and more of a thing, and clearly as you laid out, there's a lot of enthusiasm around the space at the moment, you are seeing a bunch of financial entities get interested as well. So obviously venture capital has been pouring money into the
Starting point is 00:04:37 space, but we're starting to see some new types of financial investments in AI. And I'm thinking about one thing in particular, and it is the recent GPU or chip-backed loan that was reported by the Wall Street Journal. And I think we should talk about that aspect of it, too. Totally. Because one of the things that's happening in tech is this big sort of shift from like, okay, all of your costs in the past, or a lot of them are sort of OPEX, the cost of engineers, etc. And now suddenly tech companies have to think about CAPEX for the first time. These big upfront costs that are in theory going to pay off for a long time, which in theory then changes how you should think about the financing model. Absolutely. Well, I am excited to say because we literally
Starting point is 00:05:22 do have the perfect guest. We're going to be speaking with Brian Venturo. He is the chief strategy officer at Corweave. Corweave, for those who don't know, it's probably the company right now that people most associate with being at the heart of the AI data center boomed. They have a bunch of Nvidia chips. They have investments from Nvidia right here in the sweet spot. As you mentioned, one of the interesting things that's going on is they not long ago announced a debt financing facility, sit back basically by the GPUs that they would acquire. So literally, the perfect person to understand like the business of these.
Starting point is 00:06:05 AI Cloud Data Center operation. So Brian, thank you so much for coming in. Thanks for having me. It's the second time I've been on the podcast. That's right. We talked to Brian years ago. It's interesting to think about at that time because I think that it may have been like 2020 or 21. And the excitement then was that these chips could be used for crypto mining and other things like sort of distributed video editing and stuff like that. And then Ethereum stopped using mining, but it was sort of fortuitous timing because right around Then AI went crazy and that's probably, I don't know, in my view, maybe a higher use of these chips. Before we get to that, do you worry about vibration in your data centers?
Starting point is 00:06:45 So everywhere that's close to a fault line is designed around that and is part of code. So, you know, the engineering firms that help us build these data centers have taken all of that into account. And all of our racks are, you know, seismically tuned to make sure that we can withstand the normal vibration from the earth. So yeah, it's been something that's been in those manuals for a long time. Some of our hardware manufacturers actually have vibration testing labs where they put the racks on top of a big kind of platform that shakes and it's pretty dangerous and uncontrollable and hard to watch. But, you know, there's people out there that have been solving this problem for decades now. I miss the boat on that business, Joe. It sounds like it's been dealt with decades ago.
Starting point is 00:07:29 Okay. Well, actually, why don't I start with a very simple question, which is when, when you're looking at the business of CoreWeave. So a specialized cloud service provider, let's put it that way. What are the different components that you have to think about? You know, Joe kind of alluded to all these different ingredients that go into the business, but walk us through what those actually are. Sure. So there's three pieces that as a management team, we think, are incredibly critical to the business. The first is, you know, our technology services that we provide on top of the hardware, right. And this is everything from the software layer through the support organization to, you know, how we work with our customers. This isn't the type of thing that you just go plug in and it works in these large supercomputer clusters. There may be 200,000 infiniband connections that connect all the GPs together. And if one of those connections fails for whatever reason, the job will completely stop and have to restart from its previous checkpoint. So, you know, everything that we do on the software side and engineering side is to make sure these clusters are as resilient and performant as they possibly can. be to ensure, you know, our customers can run their jobs, you know, increase efficiency,
Starting point is 00:08:39 and get all of the kind of monetary value they can out of the chips. So technology piece is really hard. It's something that I think is very overlooked by the market. But it's just as hard as the two other kind of pieces that this business stands on. The second is, you know, the physical nature of the business in that you have to actually build and run these data centers. And those hundreds of thousands connections inside the supercomputers, like somebody has to has to go put those together and make sure they're clean and make sure they're labeled correctly to be able to remediate failures. And when you're building a 32,000 GPU supercomputer that is one of the fastest three
Starting point is 00:09:15 computers in the planet, you know, you're running thousands of miles of cable inside a very dense space, right? These data centers are built very tiny to make sure that you can connect everything together and that becomes a huge logistical challenge. So, you know, the data center piece, which we're going to talk more about today, is very challenging to design for the use case. And then the third piece is, how the hell do you finance the whole thing? Right.
Starting point is 00:09:40 And, you know, we've been very successful in the financing aspect of this. But, you know, whether you're financing technology operations or the physical build of these things, it is an incredibly capital intensive business. And constructing those financial instruments to back our business is very hard. And we have to be very, very thoughtful around who the counterparties are. How do we think about credit risk? How do our investors think about that? credit risk. How do we deal with contingencies inside the contracts to make sure that they are
Starting point is 00:10:08 financedable on the scale that we've done over the last 18 months? Talk to us a little bit more. We could probably talk about data center financing credit and have that be a whole episode. But when you think about, you have to think about your counterparties credit risk. Talk to us a little bit about what your, who those are, what the type of entity is. Sure. So I'll get myself in trouble if I just start naming them off. Yeah. I know. Some of them. them are more public than others. I'm going to refer to them as, you know, hyperscale customers. We have AI lab customers. We have large enterprise customers. We've really constructed our portfolio of business around the idea that, you know, if we're going to build $10 billion of infrastructure
Starting point is 00:10:50 for somebody, we have to know there's a balance sheet we can lean into behind it, right? And we're, the pace at which we've grown, you know, our customers are demanding scale so quickly that the credit of the counterparty is incredibly important to find the low cost of capital we have with these credit facilities we've announced. Right. So, you know, when people talk about how this is a credit facility backed by GPUs, it's not really backed by GPUs. It's backed by, you know, commercial contracts with large international enterprises that may
Starting point is 00:11:20 have AAA credit, right? So, you know, it's the framing of that. Trade receivables finance, basically. Yeah, it's closer to trade receivables financing than it is, hey, we're going to go leverage up a bunch of GPUs and see what happens. Okay, well, walk us through the, I guess, like the sequence in some of these financing agreements. So, you know, if a customer comes to you and they say, we want a certain amount of compute, can you do this for us? And you start going down the process of like, okay, what do we need to make this happen?
Starting point is 00:11:50 What do those like financial agreements actually look like? And who's bearing the initial risk? Is it the customer or is it you? Good question. So when we're approached by a customer, right? You know, the ask is typically going to be pretty general. And they're going to say, hey, we're looking for capacity in Q1 of next year. What's the largest thing you can do?
Starting point is 00:12:11 And, you know, we take that effectively as a mandate of, okay, hey, you know, this customer we've done business before, you know, we're really comfortable with them. We know that we're going to get a contract done. We'll go out and we'll try to secure an asset to, you know, to go build it. And we may have it in our portfolio already. We may be, it may have been a strategic investment that we made. But once we find the data center asset, that's, that's, you know, when we go back at the customer and say, okay, like we can commit to doing this. This is the timeline.
Starting point is 00:12:34 We'll structure a contract around it. Depending upon who the customer is, there may or may not be some credit support associated with it around the scaling of that asset. And then we'll get a commercial contract in place. And we will initially fund a large portion of that project off of our own balance sheet. Right. It's why you also see us raising equity, right, is we have to have the capital to accelerate the business. And then once we have that and we're making progress, you know, Think about it as you're building real estate, right? You have a construction loan and then you have a stabilized asset loan. And we basically fund the construction loan piece off of our balance sheet.
Starting point is 00:13:08 When we get to a more stabilized asset, that's when we go out and kind of do that trade financing or trade receivables financing with our partner lenders. You know, they worked with us before. They know that these things are going to stand up. They know how they perform. And at that point in time, it's pretty easy for them to underwrite that risk.

Bloomberg's Surveillance, Essential Listening, each and every business day. It's funny, Tracy and I had coffee with someone yesterday who is, sort of in the space. I want dox him here. And I was like, what should we ask Brian? And he's like, ask him why he won't let my company, why I'm still on the waiting list or something, or why he
Starting point is 00:14:53 hasn't approved my company to use core wave. But what are some of the bars or the threshold? So, you know, apparently there's a lot of demand for compute these days. What does it take to get in the door and get access to some of your chips and electricity? So it's a great question. It's a question that we get all the time from our sales teams, right, is, you know, we're faced a lot with a sales team that is incredible at delivering product to customer, and we don't have anything to sell. And it's kind of my job as the strategy organization at core. We're responsible for two things. It's product and infrastructure capacity. And, you know, I spend most of my time going out and finding those data centers and being able to support those deals. And the growth that we had over the past
Starting point is 00:15:39 12 months, the company was pretty flat out, right, in building and delivering this infrastructure, you know, publicly on our documentation page, it says that we have three regions. We'll have 28 regions online by the end of the year. I think we delivered 11 of them in Q1 alone, right? So we're building at a scale, you know, I'd say that almost larger than some of the three big hyperscalers. But in terms of how do you become a customer of core weave, it's really relationship driven, right? Is we want to make sure that we're going to be able to be successful with our customers and have an engineering relationship and we're aligned in what they need and we can deliver what they need. The last thing that we want is for somebody to walk in the door and say,
Starting point is 00:16:16 hey, I need this for three weeks and two weeks into it. They're unhappy and we can't give them what they need to be successful, right? Our customers are making such large investments in this infrastructure that we have to have, you know, a lot of conviction that we will be successful with them and provide a good experience. So it's not that we're trying to keep people out. It's we're trying to ensure positive experiences for people that we do bring onboard. Do you build complete housed facilities or is it all you're going to bring your chips and expertise into an existing tier one data center and essentially rent floor space from them? Yeah. So a year ago, it was, we were effectively just a co-location tenant and now we've gone a lot more vertical for some
Starting point is 00:17:00 strategic builds where we're either a partner in the project where we own equity in the development company or we're building the project ourselves. We've been scaling that team up over the past six months and we had to at our scale to be able to guarantee outcomes, right, is we were in a position where we had data centers getting delayed with things that weren't communicated to us. And, you know, we had to go build the capability to handle that situation and, you know, make sure we can still deliver for our customers. One of the differentiators that you and some of your colleagues have emphasized previously is this idea that you're designing the server clusters kind of from the ground up, whereas, like, other hyperscalers maybe are doing it on a sort of
Starting point is 00:17:40 different mass scale. But can you walk us through, like, what is the benefit of doing it that way? And then secondly, does that end up being an impediment to, I guess, efficiencies or economics of scale? And how customized, like, do you really get here? So from a customization perspective, it's aggressive, right? And I say that because, you know, our customers are involved in the design of, you know, our network topology of the East-West fabrics for the GPU-to-GPU communication, for things like cooling. You know, I have customers that tour the data centers under construction process with me like once a week. And it's to the point that they're impacting how we build the base-level networking products to ensure they have enough throughput to, you know,
Starting point is 00:18:27 meet their use case needs. Whereas in, you know, what I, what we call the legacy hyper-scaler installations, it may be they have a couple thousand GPUs that are in a data center that was really built for CPU computation or provide services to 10,000 customers, that is really with a much lower base expectation of what they're going to be doing. Right. So it's things around connectivity for storage. It's things around power and cooling. It's things around how they want to be able to optimize their workloads inside of the GPU to GPU communication. You know, we have some customers that even customize their infinibate fabrics and the size of those fabrics and how they connect together. So, you know, we work with them to really understand what their use
Starting point is 00:19:08 cases, where they're worried currently and in the future and a design around that. So it's a pretty comprehensive program when we're building something from the ground up. And how much complexity does that introduce into the business? And does it end up being a limiting factor on your growth? Or is demand just so strong at the moment that it's not really an issue. The customization that we do is typically going to be above what our base level offering is, meaning the environment will be more performant because the customer required it. So it's typically not going to be limiting to us from a future revenue or resale perspective. It's going to make the asset more valuable. But we're designing our reference builds for 99% of use cases and we're trying to price it
Starting point is 00:19:50 efficiently. And then when customer wants something above and beyond, it impacts price. But for these installations, it's probably de minimis. Right. So, you know, it doesn't really add a lot of complexity for us in a business perspective. So we're happy to do it. You mentioned that some of the hyperscalers, yes, they have GPUs, but they were like built in an environment for like legacy CPUs. Can you talk a little bit about a just the difference between the legacy architectures and the new one? And then in the design, like what kind of bottlenecks you run into? Is there issues with labor, like the types of people who know how to string these things together well, or other different cooling requirements for this type of compute environment that did not exist? Like, what are the,
Starting point is 00:20:36 what are the challenges in building out this sort of like fundamentally different environments? Yeah. So that's changed also in the last 12 months in that you used to be able to take what was an enterprise data center and, you know, creatively retrofit it to be capable of supporting the AI workloads to a certain density level. Okay. Right. Like instead of filling up a cabinet, you could put two servers in a cabinet and you could meet the power and cooling requirements of the installation.
Starting point is 00:21:02 It used a lot more floor space, but it was doable. One of the incredible things about Nvidia is that they're always pushing the boundary on the engineering side. And their next generation of chips is largely dependent upon much more aggressive heat transfer. And they've introduced liquid cooling to the reference architectures. So as liquid cooling comes in, it changes what type of data center is capable of doing this and it truly requires that ground up redesign and almost greenfield only build to support it is you've gone from an environment where you could take an enterprise data center and deploy
Starting point is 00:21:35 less servers per cabinet and get away with it to hey nobody's ever built this before it's at an incredible scale and it has to happen on a yearly cadence now so the data center industry is in a full sprint to figure out okay how do we do this how do we do it quickly how do we operationalize it And, you know, that's kind of where I've been spending all of my time over the past six months. Can I ask a really basic question? And we've done episodes on this, but I would be very interested in your opinion. But why does it feel like customers and AI customers in particular are so, I don't know if addicted is the right word, but like so devoted to invidia chips? Like what is it about them specifically that is so attractive? how much of it is due to like the technology versus say maybe the interoperability.
Starting point is 00:22:26 So you have to understand that when you're an AI lab that has just started and it is a, it's an arms race in the industry to deliver product and models as fast as possible, that it's an existential risk to you that you don't have your infrastructure be like your Achilles heel, right? And Nvidia has proven to be a number of things. One is they're the engineers of the best products, right? They are an engineering organization first in that they identify and solve problems. They push the limits. You know, they're willing to listen to customers and help you solve problems and design things around new use cases.
Starting point is 00:23:06 But it's not just creating good hardware. It's creating good hardware that scales and they can support at scale. And when you're building these installations that are hundreds of thousands of components on the accelerator side and the Infiniband link side, it all has to, work together well. And when you go to somebody like Nvidia that has done this for so long at scale with such engineering expertise, they eliminate so much of that existential risk for these startups. Right. So when I look at it, I see some of these, you know, smaller startups saying, we're going to go a different route. I'm like, what are you doing? Right. You're taking so much
Starting point is 00:23:38 risk for no reason here. Right. This is a proven solution. It's the best solution. And it has the most community support, right? Like go the easy path because the venture you're embarking on is hard enough. Is it like the old, what was that old adage? Like no one ever got fired for buying Microsoft. Or IBM, yeah, yeah. Yeah, or IBM, something like that. But the thing here is that it's not even nobody's getting fired for buying the tried and true and slower moving thing. It's nobody's getting fired for buying the tried and true and best performing and, you know, bleeding edge thing.
Starting point is 00:24:11 Right. So I look at the folks that are buying other products and investing in other products almost as like they're trying, they almost have a chip on their shoulder. and they're going against the mold just to do it. There are competitors to Invidia that they claim cheaper or more application-specific chips. I think Intel came out with something like that. First of all, from the CoreWeave perspective, are you all in on Invidia hardware?
Starting point is 00:24:38 We are. Could that change? The party line is that we're always going to be driven by customers, right? And we're going to be driven by customers to the chip that, is most performant, provides the best TCO, is best supported. And right now, and in what I think is the foreseeable future, like I believe that is strongly in Vidian. Thinking about, okay, maybe one day you guys IPO, and I'm looking through the risk factors and one of the risk factors,
Starting point is 00:25:05 we have a heavy reliance on Nvidia chips. There is a risk that a competitor thing, what would it take for one of these competitors that does ostensibly offer cheaper hardware or perhaps lower electricity consumption? in your view to make one of those risk factors real? I think that they'd have to be willing to, quote, unquote, buy the market. And when I say that, I mean they'd have to subsidize their hardware to get a material market share. And from what I've seen, there's no one else that's really been willing to do that so far.
Starting point is 00:25:38 What about meta with pie torch and all their chips? So they're in-house chips. I think they have those for very, very specific production applications. but they're not really general purpose chips. Okay, right? And I think that when you're building something for general purpose and there has to be flexibility in the use case, while you can go build a custom ASIC to solve very specific problems,
Starting point is 00:26:00 I don't think it makes sense to invest in those to go, to be a five-year asset if you don't necessarily know what you're going to do with it. So you talked about the advantages of Nvidia hardware, like the chips themselves. But one of the things you sometimes hear is that those same chips might perform differently in different clouds. So what is it that you can do to sort of boost the performance of the same chip in your structure or ecosystem versus, say, an AWS or someone like that? Sure. Great question. We do a lot of work around this internally, and it's a big part of our technical differentiation. And what we call it internally is mission control. And mission control is
Starting point is 00:26:40 effectively a portfolio of different services that we run on our infrastructure to make sure that these incredibly complex super computers are healthy and performant and are optimized, you know, where we take a lot of that responsibility off of our customer engineering teams, right? And it sounds like that might be an easy lift, but when you're running supercomputer scale, you know, you need a team of 50 to do that, right? So we provide a ton of software automation around that, providing that health checking and observability to our customers, but it's also the engineering engagement, right, is, you know, working with our customers to understand, okay, what are you doing? What's the best way to optimize this? How do we, you know, how did we design
Starting point is 00:27:18 the data center to be more performant to make sure your storage solution was correct? Your networking solution was correct. So it's not just a, hey, CoreWeave provides like this one little thing that makes it better. It's the comprehensive solution starting from the data center design through the software automation and health checking and monitoring via mission control via the engineering relationships that really add that value. Let's talk about electricity because this has become this huge talking point that this is the major constraint. And now that you're becoming more vertically integrated and having to stand up more of your operations, we talked to one guy formerly at Microsoft who said, you know, one of the issues is that there may be a backlash
Starting point is 00:27:55 in some communities who don't want, you know, their scarce electricity to go to data centers when they could go to household air conditioning. What are you running into right now? Or what are you saying? So we've been very, very selective on where we put data centers. We don't have anything in Ashburn, Virginia, right? And the northern Virginia market, I think, is incredibly saturated. There's a lot of growing backlash in that market around power usage. And, you know, just thinking about how do you get enough diesel trucks in there to refill generators that they have a prolonged outage, right? So I think that there's some markets where it's just like, okay, like, stay away from that. And when the grids have issues, and that market hasn't really had an issue yet, it becomes an acute
Starting point is 00:28:36 problem immediately. Like, just think about the Texas power market crisis back in, I think it's 2021, 2020, where the grid wasn't really set up to be able to handle the frigid temperatures and they had natural gas valves that were freezing off at the natural gas generation plants that didn't allow them to actually come online and produce electricity no matter how high the price was. So there's going to be these acute issues that people are going to learn from and the regulators are going to learn from to make sure they don't happen again. And we're kind of citing our plants and markets where our data centers in markets where we think the grid infrastructure is capable of handling.
Starting point is 00:29:10 it, right? And it's not just, is there enough power? It's also on things, you know, AI workloads are pretty volatile in how much power they use. And they're volatile because, you know, every 15 minutes or every 30 minutes, you effectively stop the job to save the progress you've made. Right. And it's so expensive to run these clusters that you don't want to lose hundreds of thousands of dollars of progress. So they take a minute, they do what's called checkpointing where they write the current state of the job back to storage. And that checkpointing time, your power usage basically, goes from 100% to like 10%. And then it goes right back up again when it's done saving it.
Starting point is 00:29:45 So that load volatility on a local market will create either voltage spikes or voltage sags. And a voltage sag is what you see is what causes a brownout that we used to see a lot of times when people turn their air conditioners on. And it's thinking through, okay, how do I ensure that, you know, my AI installation doesn't cause a brownout when people are turning their, you know, during checkpointing when people are turning their air conditioners on? And like, that's the type of stuff that we're thoughtful around, like, how do we make sure we don't do this? Right.
Starting point is 00:30:13 And, you know, talking to engineers and Nvidia's engineering expertise, like, they're working on this problem as well. And they've solved this for the next generation. So it's everything from, is there enough power there? What's the source of that power? You know, how clean is it? How do we make sure that we're investing in solar and stuff in the area to make sure that we're not just taking power from the grid to also when we're using that power, how is it going to impact the consumers around us? I want to ask you more about what investment. video is doing, but just on that note, what's the most important metric for evaluating a data
Starting point is 00:30:46 center's quality or performance? Is it like days without brownouts or an interrupted power supplier? Is it measures of efficiency like power usage effectiveness or something like that? If I'm surveying a bunch of data centers, I want to pick a good one. What should I be looking for? So right now, the market's pretty thin. I don't have a lot of options. Okay. Imagine I'm like the biggest customer on earth and I can get in anywhere. What should I be looking for? So it's, the first thing goes back to the electricity piece, right? Is the grid stable? Is there enough power supply? You know, is there excess renewable generation in the area that doesn't have the ability to make it to downstream consumers? A lot of the renewables that we have in the
Starting point is 00:31:29 U.S. are built in places that don't necessarily have the consumers. So you're citing these data centers in places where you have this excess supply. So that's the first piece, right? is how good is the electricity supply and how angry are the people around me going to be if I take it? Now, you go from there into, everything else is kind of solvable, right, and the way that you design it.
Starting point is 00:31:50 And if you're building a greenfield, it's okay, you know, what type of UPS systems am I putting in? Are they capable of handling that load volatility? You know, how am I thinking about my cooling solutions? There's been a big shift to liquid cooling, right? And liquid cooling from a PUE perspective isn't a 30 to 40% decrease in electricity utilization like people think.
Starting point is 00:32:13 It's more like 60 to 70%. Right. And the reason for that is it's not just the efficiency of the data center plant. It's also that now if you're not cooling things with air, you don't have to run the fans inside the servers as well. And for these AI installations, because they're so dense, the fans consume a lot of energy. Right. So everything that we're building now is a combination of liquid and air cooling. right and the liquid cooling piece has solved the PUE issue right and we're everything we're doing
Starting point is 00:32:42 is trying to say okay how much power can we use only for running our critical like IT operations versus cooling the environment making sure the environment's running correctly from a resiliency perspective and there's been big strides made there over the last 12 months I'm Matt Miller and I'm Hannah Elliott inviting you to join us for the Bloomberg Hot Pursuit podcast every week we bring you news and industry insight on everything cars. And we do a whole lot more than just talk about cars, Matt. We actually get behind the wheel of basically every latest model, especially the luxury ones and the sports cars, direct from the showroom floor.
Starting point is 00:33:35 It really is remarkable how many cars we have access to. I feel a little bit guilty about it, but everything from $40,000 EVs to exotic half-million-dollar supercars. We also speak with the insiders who shape the automotive industry from the top CEOs and collectors to visionary designers and racing champions.

Listen to us talk about what we are driving this week. That's Bloomberg Hot Pursuit.
Starting point is 00:34:07 I'm Matt Miller in New York. And I'm Hannah Elliott in Los Angeles. Subscribe today wherever you get your podcasts. Does co-location trump grid reliability? Like if I'm Elon Musk building some sort of new AI thing, as I think he's doing, in Texas, say, like, am I just going to have to find a data center in Texas? Or how much flexibility do I have to use one further away? So great question.
Starting point is 00:34:35 It's a different answer for different use cases at different times. And right now, you know, we're in the middle of this rush to train whether they're open source or proprietary foundation models, the largest, most valuable companies in the world, and they're mostly worried about access to contiguous compute capacity, right? How much compute can I get in one location all connected together so I can go faster than the next guy? But when the models are trained, they want that compute to then be local to their customer base, right?
Starting point is 00:35:06 How do they take it from the middle of nowhere and then go serve it in the metropolitan markets? And as the use cases are more distilled and they get more real time, think like the type ahead suggestions that you get in your Gmail account, right? As you're typing something and it's getting better and better, it's, you know, that's an AI model somewhere, like predicting what you would want to say next. And they want to make sure that's delivered at human speed. So that human speed is a latency consideration, right? As you're citing those GPUs and you're citing that compute to be local to the people that are
Starting point is 00:35:37 using it. So that move has started probably four months ago where we saw customers finally become concerned around latency for their serving use cases. So initially training people don't really care where it is, cheap power, reliable grid, they just need it all contiguous and they need it fast. And then down the road as their applications find success, they're more worried about where the compute is for their customers. What are some of the areas that are going to be the next Northern Virginia when it comes to data center clusters? So I think we're seeing it in Atlanta already where Georgia has paused or has attempted to pause some of their tax incentives.
Starting point is 00:36:15 around it because they want to make sure they do grid studies. I think that we're probably going to see it in some of the other hotspots. You know, you see AWS up in Oregon who was trying to find creative alternative ways to power their data centers from non-grid generation to alleviate some concerns there. But, you know, I think that the market has to solve this problem. And, you know, you're starting to see some of the startups around nuclear generation in the small reactors at the data center level as people are, you know, being thoughtful for five to ten years from now.
Starting point is 00:36:50 Do you have any influence on the type of power being built in certain areas? You know, could you say to a utility company of some sort, we're here, we need access to energy, but we want it to come in a particular form? So you can, but you have to understand that the investment cycles and the physical build cycles for those are so much longer than, you know, how quickly our customers need infrastructure, right? So you may go to a market and say, hey, we're going to be here over the next 10 years. We'd like you to install XYZ, you know, renewable. And they're happy to do it.
Starting point is 00:37:23 It's just that you have to find a medium-term solution while that's being built. I'm going to ask a question. So there was a news story, and maybe you won't comment on the news story specifically, about CoreWeave having made a $1 billion offer for a Bitcoin miner called Core Scientific. apparently was rejected according to things I've read in the news. Setting aside this deal, there's, you know, there used to be a lot of crypto mining. And then Ethereum went from proof of work to proof of stake and that all basically disappeared overnight. There are still Bitcoin miners.
Starting point is 00:37:56 I never get the impression it's like that great a business, but whatever. Are there Bitcoin miners that have latent value in the fact that they, I mean, I know those chips don't, the Bitcoin mining chips, the actual A6 don't work for AI. because all they are is Bitcoin mining chips. But are there, by dint of their access to electricity, space, et cetera, is there a fair amount of latent value in the general physical structures that they've built for the mining? So I'm just not going to answer your question at all, and I'm going to go on a tangent. Okay, that's fine. So I think that when I think about Coreweave and what our mission is, it's to find creative
Starting point is 00:38:37 solutions to problems in, you know, various markets. And those various markets can be blocking for us and our customers to achieve our goals. So if power is a concern for us and power availability and substations and substation transformers... Bitcoin miners definitely have access to power. That is true. I'm just stating facts here. You can keep doing it. So, you know, as we go and we try to solve these problems, you know, we're going to go to places that others may not have thought of.
Starting point is 00:39:06 Yeah. And we're going to go do due diligence. And I'm going to personally go and walk the sites. And I'm going to look through and see, OK, can we pull this off? And we're going to get our engineering partners in to help us design retrofits. And we're going to do deals with the companies that we believe have the ability to provide us value. Since we're doing stuff in the news, this has been in the news for a while. So it doesn't really count.
Starting point is 00:39:32 But the new Nvidia chips, the GB 200. What will those do for CoreWeave? And when would you expect to get them? What will they do for us? It's more about what they're going to do for our customers, right? And I think that they are, this is a great question. They are going to open up a lot of both training and inference use cases in the AI side that I think our customers have been blocked by with the existing generation.
Starting point is 00:40:05 in that you're now able to link 72 of these GPUs together to work almost as one unit, and previously that was limited to eight. They have a much larger what's called a frame buffer, which is how much memory that's usable for their matrix operations. So, you know, I think that we're going to see a lot of new use cases show up for this stuff, but I think it extends well beyond AI as well, and it's going to be a lot more useful for things like scientific computing. one of the things that has me really excited is the computational fluid dynamics, and I'm specifically
Starting point is 00:40:39 thinking about the uses for that in F1 under the new regulation in 2026. I'm excited for the new platform, I think, in a year and a half, people are going to be using it for things that are different than anybody expects today. And that's, to me, the pace at which this is changing is the piece that's really cool. Wait, I'm sorry, I hate sports. What's the F1, 2026 thing? And explain how the Nvidia is. Yeah, so the F1 platform, they have very tight restrictions around what type of compute and how much compute you can use to do aerodynamic testing in your cars. And you can either do real-life testing in a wind tunnel or you can do it through CFD analysis.
Starting point is 00:41:18 And one of the great uses for the, you know, the Grace Blackwell and the Grace Hopper architectures in pairing that grace super chip with the GPU is they're great for CFD workloads. Right. And the regular. The FD stands for, oh, computational fluid dynamics. Yep. Yep. And the regulations around the existing program at F1 are, they're only able to use CPUs. They have very specific limitations around it.
Starting point is 00:41:43 But there's been a lot of talk of that changing for the 20, 2026 car models. And for me, like, that's pretty cool. And I'm gung ho excited about possibly supporting that. That does sound very fun. I want to get back to actually the financing a little bit because I guess two questions. So the logic of why you would borrow money, both, I guess, for the acquisition of chips, and the chips are sort of collateral, but I understand they're not really chip-backed loans per se. A, do you see your clients getting more into debt financing rather than equity financing?
Starting point is 00:42:22 I mean, there's a whole generation of software companies from the ZERP era that was just, you know, all equity and never had any debt at all. and they never really had to think about like their compute costs. They did, but not as much. Are you, do you think that will rise their own use of debt instead of equity in terms of their own financing? And another topic we talk about a lot on the show, private credit, like, are there, is there an emergence of an ecosystem of lenders for whom this is going to become a specialty of some sort? To the first piece of the question, I don't believe that the venture-backed kind of AI lab startups will ever take on debt. In this,
Starting point is 00:43:00 type of environment, largely because they don't have the collateral to back it if they're buying cloud services to run their infrastructure. And you may see some that start to buy their own infrastructure and to do that themselves, but it is a Herkulean task to do this at scale, right? There's a reason why clouds exist is that there's a lot of complexity that they abstract away. On the second question around, is there a private credit sector that's going to be built to do this? I think that it's more, you're seeing public lenders that are extending into the private credit space because the opportunities are there. And I'm going to give you the party line answer that my CEO gives all the time is that, you know, as we're thinking about financing our
Starting point is 00:43:40 business, the biggest thing for us is our cost of capital. And we're always going to do the things that provide us the lowest cost of capital. And, you know, the lenders that we work with, including Blackstone, that have been so wonderful for us, you know, them extending on the private credit side as we go to the public markets, because we're dragged there by cost of capital concerns, I would expect them to be involved as well, right? So I think it's a continuation of the business they've been doing in the public markets, just kind of extending into this capital intensive business. Wait, what was, I guess you can't get into specific details.
Starting point is 00:44:12 But my impression was for these types of loans that the interest rate is usually higher than like a basic bank loan or, say, issuing a corporate bond. I would definitely say our cost of capital is lower than some of the corporate issuances out there. Okay. But, you know, it's definitely higher than if our cost of capital today is definitely higher than if we were a public entity. But specifically on the GPU-backed loans. And I know you keep saying it's not really a GPU-backed loan, but that's sort of an uphill battle to call it trade receivables financing instead. It sounds so much better that way. I know, I know. But like on that in particular, okay, there's collateral. So maybe that brings the overall like borrowing rate down.
Starting point is 00:44:55 But on the other hand, it's kind of a new thing. new structure, how does that compare with more traditional types of financing? Yeah. So, you know, every credit facility that we do, the cost of capital declines, and it's declining because it's the execution risk and the ongoing concern risk are reduced, right? And, you know, when we first did this, people like, you guys are crazy, you have no history of execution. And as we've gone through and we've done it, like now there's a path that everybody that's underwriting these loans now understands, okay, this is what happens, this is how it reforms, this is what we should expect from the customers.
Starting point is 00:45:27 this is what we should expect from receivables. They get more comfortable. They're willing to do it at more aggressive rates. So the risk premium associated with it has just decreased over time. Got it. I just have one last question. I sort of touched on it earlier, but okay, we know that power is scarce. We know that, you know, there's not an infinite number of Nvidia chips, et cetera.
Starting point is 00:45:47 Like, those are quite scarce. For the other stuff, you know, we've done episodes in the past, like talking about, like, just generic electrical gear components. And we've certainly done a lot on like labor shortages. What are you seeing on that front sort of like simple gear and the sort of basic building blocks of a new construction and how difficult that is to acquire versus say if you were doing this? You know, you started in 2017. I imagine a lot of things were more plentiful back then. Yeah.
Starting point is 00:46:14 So it's not even that they're less plentiful today than they were. You know, the lead times were always the lead times for this electrical gear. It's that there was capacity to go buy off the shelf. Okay. There was inventory in the data center market, and the inventory is basically gone. And, you know, I see deals today that get brought to me, and there's seven people bidding on the same deal, and they're all trying to sell it to, like, similar customers. So the market has gotten pretty thin. So now you're looking at it going, okay, my only option here is for new build.
Starting point is 00:46:43 And you're looking at lead times that haven't really shifted that much on things inside of the data center. The substation transformers are multiple years out. And part of that reason is that it takes a year for them to cure after they're manufactured. Like there's no getting around that. There's no speeding that piece up. What does that mean it takes them a year to do? When the transformer is built that's taking on so much power, that whatever the process is, it has to sit for a year and harden before it's able to take on that electrical load.
Starting point is 00:47:12 So even if you went and said, hey, I'm going to build 10 more of these this year, it's still a year away before you can use them. Huh. Right. And those are the types of things from a manufacturing perspective. You just can't get around and it takes time for the supply chain to catch up. But, you know, the problems that I'm solving on a day-to-day basis in these builds isn't even around the substation transformers.
Starting point is 00:47:31 It's around like small components that somebody missed when they ordered the gear 16 weeks ago and now you have to go scramble and call in favors across the country of, hey, who has this part? I need it by tomorrow because I have 50,000 GPUs that are blocked by this one little thing. Right. So a lot of it is logistical and human coordination and solving dumb problems in real time. Brian Venturo, thank you so much for coming on Oblox. That was fantastic. Thanks for having me. Tracy, I'm really glad we did that conversation because there are a number of these sort of like big picture ideas in there that we've sort of hit on, of course, about data centers and AI and electricity consumption.
Starting point is 00:48:19 And it was really interesting to hear some of them. So like, for example, just this idea of like Northern Virginia is out and like needing this sort of hunt to find these spots in the country, where there is ample electricity and basically nobody local is going to get upset at you for using it. Yeah, no one will come out with pitchforks. The thing that stood out to me from a bunch of these conversations at this point is the arms race aspect of it. And how urgent building out AI is for a lot of these companies. And then there seems to be this mismatch between the immediate need for scale and compute and energy now. versus these really long timelines of actually building the stuff out. And Brian mentioning the substation transformers, taking a year to cure.
Starting point is 00:49:13 I had no idea about that. I didn't know that either, but that's a really good example. That's super interesting. And of course, now we have to do a how do you build a substation transformer. How do you cure a substation transformer? Totally. I mean, maybe this is probably something that electrical engineer is not interesting to them at all. but for me, I did not realize that there was this one year long, one year long curing process.
Starting point is 00:49:36 You know, I think there are like a couple other things that now I like want to talk more about. So I'm interested, I mean, like Corweave is an Nvidia company. It's not owned by Nvidia, but you know, it's joined at the hip in many respects. So how difficult is it going to be either for some other maker of chips, whether it's an Intel or some other maker of of software environment, whether it's meta and pie torch going against Kuda or whatever. Like that's a really interesting question to me. Like, you know, we have to do more essentially on like how much of a lock and video really has on this industry. Yeah, this seems to be the really big question.
Starting point is 00:50:17 And then the other thing I was thinking about, and I know Brian emphasized this and other core weave executives have emphasized this before, but this idea that hyperscalers maybe are starting from a point of being disadvantaged because they have to retrofit all this old infrastructure for this new AI technology. Totally. And like I can see that. But on the other hand, these are insanely impressive companies who are explicitly trying to compete against Corweave in this business.
Starting point is 00:50:49 And they're not going to stand still. And so I guess there's an open question over how much progress they're making or how fast that progress is actually happening. Right. Large incumbent companies always are going to have some challenges when there's like a new model or something. But these companies have all the money in the entire world. Right. And they also have all the, you know, one of the things that Brian said is like they, if they were, if one of them were going to do it, they would have to go out and buy a big chunk of the market. Which again, they have all the money in the entire world. So theoretically, whether it's the big companies and retrofitting the clouds or building new clouds or, you know, a lot of them like a Google, even if they're for now using their TPUs internally, primarily. Like, it does seem like in theory the opportunities out there, particularly with the sky high amount, you know, valuation that a company like Nvidia is getting.
Starting point is 00:51:42 Oh, yeah, you mentioned the sky high valuation. That was something that also stood out to me just on the financing side. So this idea of, you know, the debt financing deal that they did. And I'm not going to call it trade receivables because no one. GPU backed loans. Yeah, no one will be interested when we start talking about trade receivables. But the GPU back loan, this idea that like, okay, it's a new structure, but the more you do it, the more the cost of that particular capital starts to fall, the more the market gets comfortable with it. I mean, we can talk about whether or not it's priced correctly for a new type of unfamiliar risk.
Starting point is 00:52:18 But it does seem like that might be a new avenue for the vast amounts of capital that are needed for this business. So one, it's interesting to think about the idea that, like, you know, I don't think it's like totally true, you know, that if you need compute and scale for AI, that you don't just get to call up CoreWeave and get it. And you actually have to prove that you're going to be a good customer. And so like have something that is probably going to be sustainable, have the balance sheet capacity. So this, even if the sort of software, the end users aren't themselves raising debt, it does sound like they have to have a lot of. of equity up front just so that they're perceived as a sustainable, viable customer for a company like Corby. I also thought on the electricity front, like obviously we talk all the time about just sort of the raw demand for electricity, but this idea, what he said, and I hadn't heard anyone say it, that the runs, the modeling runs stop every, what do you say 30 minutes and have to be saved? Oh, yeah. And so you have this big variability at times, and that creates its own specific issue because it's not just steady state flow of electricity
Starting point is 00:53:28 and solving for that. That's probably another area in which the legacy data centers or cloud companies, perhaps, my guess would be that they're just sort of the demand is more constant and therefore something that would be a novelty for them. Just thinking about the financing more, I do kind of wonder how much of this is like AI built on top of AI, on top of AI. Like, to the point where if the bubble were to burst or if funding was suddenly pulled from a bunch of these startups, like what would that mean for Corweaves financing and what would that mean for Black Rock, which lent money based on the GPUs that the clients are taking on who might not be there anymore? I don't know. By the way, have you ever looked at a chart of riot blockchain?
Starting point is 00:54:17 Oh. No, it's interesting. Not for a while. Yeah, well, I mean, they're still there as a minor, but like, here we are in the midst of this pretty big crypto bull run. I mean, I guess it's cool a little bit. But, and that stock has done terribly. Yeah. So it's interesting to wonder.
Starting point is 00:54:31 And apparently it doesn't seem like anyone's made a bid for them. But it is interesting to wonder, like, okay, those chips are useless for, for AI because they don't work for that. But, you know, they do have capacity and they do have electricity agreements already in, place. So it does make you wonder whether like some of the Bitcoin mining companies, which aren't really getting a very, the market is not excited about them clearly, even in the midst of this crypto bull run. Maybe they should go back to being a diagnostics company. That's what they were before, right? Is it? I think so. I think they're one of the ones that change their name and then like they're something including blockchain and then their shares went up enormously and now they're back down.
Starting point is 00:55:15 Well, they have been, riot platforms has been around. Okay. Now I'm. curious. Yeah, so it's a Bitcoin mining company, but it's been, the stock has been around since 2003. So pretty clearly, pretty clearly they were in some other business. I don't know what I'm looking on the terminal. It says riot blockchain formerly by optics has ditched the drug diagnostic machinery business for the digital currency trade. Well, there you go. So if you have some sort of computing power or something, I don't know what they were doing before, but maybe it is interesting to think about maybe some of the option value for some of these miners, isn't there non, isn't all the infrastructure other than the Bitcoin mining operation?
Starting point is 00:55:58 Maybe we should put in a bid. Let's do it. We can crowd fund and start our own business. Okay, maybe we should leave it there. Let's leave it there. This has been another episode of the All Thoughts podcast. I'm Tracy Alloway. You can follow me at Tracy Allaway.
