Buckle up, SpaceX investors. New shares available today may mean more volatility ahead. Plus, META says one of its AI models has become the latest to go rogue and hack outside the company. The entire industry was, surprisingly to me at least, caught flat-footed by this. And why a billionaire Detroit native is planning to take down buildings that have defined the city's skyline for decades. It's Thursday, August 6th. I'm Alex O'Slef of the Wall Street Journal. This is the PM edition of What's News, the top headlines and business stories that move the world today.

We begin in Washington, where a Republican-led Senate committee has voted to hold Dr. Anthony Fauci in contempt of Congress. Last week, Fauci sat before that same committee to answer questions about his handling of the COVID-19 pandemic. He invoked the Fifth Amendment more than 100 times. The resolution the senators voted on today seeks to respond. refer the case directly to the Justice Department for potential prosecution and bypasses a vote from the full Senate, where it's unlikely to get enough votes to advance. Fauci received a preemptive pardon from President Joe Biden, but that doesn't protect him from state investigations, and four states have already launched their own.

And we're exclusively reporting that Senator Elizabeth Warren is pressing the Commerce Department for details on how changes to official inflation numbers are calculated. The plan changes, which are coming next month, are expected. to produce slightly cooler inflation readings. And economists say the changes are an effort to better capture what's going on in hard-to-measure corners of the economy. But Warren said that, in an environment where the Trump administration has politicized economic data, changes to statistical methods warrant deeper scrutiny. Meta said that one of its AI models went rogue during cybersecurity testing.

The model was able to access the internet because of a, quote, misconfiguration in a hacking test conducted by a third-party AI testing company. It's the latest in a series of similar disclosures from AI companies, suggesting that incidents like these are becoming more common. For more, I'm joined by journal tech reporter, Sam, what happened with this latest hack? What model was it? And when was it? And where did actually hack into? Those are all great questions. And I'm really hoping we get the answer to them someday. What we know so far is that there is a third-party company that does cybersecurity testing of AI models called Irregular. It works for all the big

labs and it made it into the news in recent weeks because it was involved in some of the earlier hacks where AI models got onto the internet and hacked another company. And in this case, Meta also used them. And basically this misconfiguration error means that the environment where the cybersecurity test of the model was happening was actually connected to the internet and they weren't stopped from going out and actually hacking real targets. As you note, Irregular seems to be at the heart of a few of these hacking incidents. It also conducts tests for Anthropic and OpenAI, but it doesn't appear to be involved in the more sophisticated hugging face hack. So do we know what role a regular might be playing in these

incidents? Irregular says that this cybersecurity test that they were running had this problem, which they had fixed. I think that they're more represented. of the way in which the entire industry was, surprisingly to me at least, caught flat-footed by this. This is something that AI safety experts have been warning about for some time. We're not necessarily seeing that this has to go to some horrible sci-fi place, but what we're seeing is that with the increased capability of these AI models, that there are some emergent properties.

It's not just that they're good at hacking, but they seem to like to cheat on their test. in order to achieve their objectives more quickly. It sort of reminds me of stories about genies. When you have this all-powerful entity and you ask it to do something, you better make sure you're very specific in how you tell it to do that because, as we all know, genie's stories do not end well for the person making the wish. Journal tech reporter Sam Checkner, thanks so much.

Always a pleasure. In markets, indexes were lower today. The Dow broke its five-day winning streak to fall 0.9 percent, as shares of Salesforce, Boeing, United Health, and others dragged it lower. The NASDAQ slipped 0.1% and the S&P 500 dropped 0.2%. Oil climbed as investors await updates on a possible deal to reopen the Strait of Hormuz. Brent Crude, the International Oil benchmark, rose 3.8% to $82.49 a barrel. One stock that many investors were paying attention to today was SpaceX.

It's had a bumpy ride since the company first went public in June. After briefly shooting up 25% over its list price, SpaceX stock has fallen more than 30% from where it started as of yesterday's close. Today, there was a development that threatened to make things even rockier. More than 900 million SpaceX shares unlocked today worth more than $100 billion. Mark as reporter David Uberti joins me now. David, what does it mean that shares are unlocked and why could that make the stock more volatile? So essentially after an IPO, you will have a period at which early investors in a company or a company, company insiders, current or former employees have to hold on to their stock before they can actually

start trading them into the market. And today, we saw the first tranche of those stock become available to trade. 900 million shares, as you mentioned, that's more than the total number of shares that were previously tradable. So if you think just in terms of pure supply and demand, a huge amount of supply is now potentially flooding the market going forward. So that's why you're seeing a lot of investors in Wall Street sort of brace themselves for more volatility ahead. And yet, the stock closed up more than 6% today. So I guess we're not going to see that volatility right away necessarily. It could happen going forward.

And obviously there's a huge question over the extent to which those insiders will decide to cash in. When SpaceX went public, Musk paid special attention to everyday investors. How are they feeling about the stock now, given all of this volatility? We've spoken to retail investors in recent days and weeks, and they are really bullish on this stock. They are buying in to this future. of asteroid mining data centers in space, even the Mars space idea as well. And as my colleague Hannah Lange and I discovered, over the course of SpaceX being public, every single day since it's been trading retail investors, people like you or I have been net buyers of the stock.

So even as there's been this big sell-off, all of the retail investors at home who are buying into that musk vision of the future are really ramping on their bets for this company to improve and succeed in the long term. General Markets reporter David Uberti. Thanks, David. Thanks. Coming up, a billionaire has already reshaped Detroit's downtown. Now he's coming for its waterfront. More after the break.

The UK government has cleared paramount's $81 billion deal for Warner Brothers Discovery after the company promised editorial independence of the combined company's television and streaming services. The decision clears a hurdle for the deal, though it still faces substantial legal. challenges in the U.S., where state attorneys general have sued to block the purchase. A trial in that case is set for March 27. We turn now to Detroit, where billionaire Dan Gilbert has undertaken a project that's set to remake the city's skyline. The Detroit native and his financing firm Bedrock have taken on the $1.6 billion project that would center around the city's waterfront. It would also mean

taking down two towers that make up part of the Renaissance Center complex that currently defines it. Nicholas Miller covers real estate for the journal and is here to tell us more. Nicholas, who is Dan Gilbert and how did he find himself working on this project? Dan Gilbert is the co-founder of Rocket Mortgage. He's a billionaire. He's made his money selling mortgages. Dan Gilbert is a Detroit native. And he has been investing in the city for more than 15 years. Up until now, he has concentrated his investment in the downtown area.

He started doing this kind of at a really difficult time for Detroit. The city filed bankruptcy in 2013. There was little investment to speak of. And kind of thanks to his investment, he has made it rather vibrant part of the city. So it sounds like there have been some upsides to the redevelopment that he's done already in Detroit's downtown. But did it go over well with all of the residents there? It is somewhat controversial in the sense that a lot of Dan Gilbert's projects have received some form of public subsidy. And there is some debate about whether those subsidies would be better suited going to parts of the city that need them more.

When this project was proposed, Dan Gilbert and Bedrock were seeking an expansion of a state tax credit program. There was resistance from some political leaders in the state to giving state subsidies for this kind of project, people talking about corporate giveaways. But in the end, Bedrock and Gilbert were really successful in convincing officials of their vision for the riverfront and how that can kind of draw young, talented, educated people and the economic revitalization that comes with them to Detroit. What is Gilbert looking to change? And what does he think that'll bring to the city? So what he wants to do is he wants to take down two buildings in the Revisant Center, which is the seven skyscraper complex that has defined Detroit skyline. for decades. And he wants to install a riverfront park, an entertainment district, and new housing as well. And the idea is that this is kind of the phase two of his strategy to remake Detroit. And the hope is

that all of these public amenities will encourage people to move to Detroit. It's an interesting project because cities once focused on building office buildings and northern to woo companies. But since the pandemic, cities have for the most part struggled to fill their office buildings. In this case, bedrock is taking down two office buildings and putting up public space instead. The theory goes that by creating kind of a quality sense of place, including bars, restaurants, parks, concert venues, attractive riverfront, you can draw those kind of young professionals and then you attract businesses who want to employ that talent, which creates new jobs and kind of brings this virtuous cycle.

How big a risk is this for Gilbert and for Detroit? It definitely is a big bet that this kind of development will, in fact, bring people from across the country. The idea is that they want to turn Detroit into Nashville or Austin or Raleigh, where it kind of gains its reputation as an attractive place to live. But it is a big bet. Detroit still has big weaknesses that could get in the way of this initiative. It's public school systems still kind of have a long way to go.

It really has little public transit to speak of. And so there is some risk that even with, thriving new riverfront, Detroit may not be able to draw all the kinds of residents and activity that it wants. That was WSJ reporter, Nicholas Miller. Thank you, Nicholas. Thanks so much. And that's what's news for this Thursday afternoon. Today's show is produced by Anthony Bansy. Our supervising producer was Matthew Walls.
