Americans love using their credit cards, the most secure and hassle-free way to pay. But DC politicians want to change that with a Durban Marshall credit card bill. This bill lets corporate megastores pick how your credit card is processed, allowing them to use untested payment networks that jeopardize your data security and rewards. Corporate megastores will make more money and you pay the price. Tell Congress to guard your card because Americans lose when politicians choose. Learn more at guardyourcard.com.
More than a trillion dollars have been erased from the US stock market. Tech stocks dropped after China's deep-seek released a cheaper AI model. Plus, is this the correction in AI stocks investors were expecting? Today is one of the big first pullbacks against that theme that we've seen over the last year or two. And it has raised in a really big way whether the market has overvalued some of these stocks.
And a top prosecutor has opened a review of the Justice Department's decision to charge hundreds of defendants of the January 6th riots. It's Monday, January 27th. I'm Alex Osala for The Wall Street Journal. This is the PM edition of What's News, the top headlines and business stories that move the world today.
An artificial intelligence model from the Chinese company DeepSeek has sparked a deep freak out among investors. NVIDIA stock tumbled nearly 17%, wiping out about $593 billion from the company's market cap. Makers of AI infrastructure such as Oracle, Super Microcomputer, and TSMC also suffered deep declines.
That pushed several major U.S. stock indexes down, though the Dow edged nearly 0.7% higher. The Nasdaq fell about 3%, and the S&P 500 declined about 1.5%. The reason? A Chinese artificial intelligence company called DeepSeek.
Last week, the company put out a paper that said it had created an accurate AI model that had trained for relatively cheap, about $5.5 million. Compare that to the $100 million to $1 billion it took to train a recent model from Anthropic, according to that company's CEO.
The development has pulled the rug out from under global companies riding the AI wave, including chip makers, infrastructure suppliers, and energy companies, as investors question the outlook for AI spending. This comes at the start of a busy week for earnings. Some of the biggest spenders on AI, such as Microsoft and Meta, are due to update investors.
We'll see a bit later what explains the market's frenzy and what's to come. But first, let's talk a bit about the company behind it all. Asa Fitch, who covers semiconductors for the Wall Street Journal, joins us now. So, Asa, how much of a surprise is this? Did this company just come out of nowhere?
Well, it did and it didn't in a sense for a lot of people did come out of nowhere. They'd never heard of this company DeepSeek. But DeepSeek has been around for a couple of years driven by an entrepreneur in China who's actually a hedge fund guy who does quant investing in China.
What really has caught people's attention is the release of a new model last week by DeepSeek that could rival the performance of some of OpenAI's most sophisticated AI systems. So this was what really led people to think, wow, there's something to this Chinese company and what they're doing and they could disrupt the entire AI ecosystem. What is unique about this model that they just published this paper on?
The interesting thing about this model really is how little it needed in terms of computing resources to do what it did. These companies like OpenAI, like the big tech companies, have been throwing billions upon billions of dollars around buying GPUs. These chips are needed to train AI models.
And what DeepSeek did suggested that you can do the same sorts of things with less. So that's kind of what has led to this kind of surge in interest in DeepSeek and the surge of worry around people who have invested in these companies at the forefront of AI. How did DeepSeek manage to come up with its product, given the US sanctions on exports of the most sophisticated chips to China?
Well, that's complicated. They have a bunch of chips. First of all, they have around 2000 of some of the videos chips that are available in the Chinese market still. They're not the most powerful chips the company makes. Deepseag also had a large cluster of videos earlier generation of chips before there were these export controls on China.
It's not really entirely clear how DeepSeq was able to train up this big model and do these things with apparently fewer chips. Some of the papers that have been published suggests that they spent much less, but there are a lot of gaps in those assertions. We're not entirely sure yet exactly how much computing power DeepSeq needed, but everybody pretty much is impressed with what they've been able to do nonetheless. What can we make of the fact that DeepSeq's code is open source?
That's another thing that's really been impressive to a lot of people. It's not one of these closed source things where everything's hidden behind a wall and they claim this performance and so on and so forth. People can kind of see what they did. They can check their work and they can see that they used all these techniques to do what they did and it seemed to have worked out. So that itself is pretty notable and gives them more credibility because it's all been done out there in the open.
So given the sort of freak out in the broader tech sector semiconductor companies today, where do we go from here?
Well, the real question is how much these techniques actually apply to other models. And if you look at this question about the broader impact, the answer really revolves around how much the rest of the world adopts the same strategies. I mean, there's open source, as we were talking about before, and that means that anybody else can use the same techniques. And then what that means for the general need for computing power for these things.
If you look at some analyses and situation, some people say it may not mean very much at all. We still may need to develop very, very big models. Maybe we can do that more efficiently. But another way of looking at it is that as people continue to use these models, the work shifts toward actually deploying them. If you have all these consumers in the world using these things, even if you don't need as much computing power to train these things, you're still going to need an increasing amount of computing power to
maintain and to deploy them. That was WSJ reporter, Asa Fitch. Asa, thank you so much. Thank you. Coming up, markets have been rattled. Where might they go from here? That's off to the break.
DeepSeek's impact on the stock market today isn't just limited to tech companies, but what investors want to know is, will the slump stick around? Here to talk about it is David Uberti, who covers markets for the Wall Street Journal. David, what about this has got the market so spooked?
Well, the market has been riding so high over the last year or two, in large part because of a lot of this AI hype. And the big question surrounding it all has been how to price all of this. What is the actual value that AI brings to the broader US economy? And compared to earnings through corporate earnings statements and such, today is one of the big first pullbacks against that theme that we've seen over the last
year or two, and it has raised in a really big way whether the market has overvalued some of these stocks. If there is, in fact, a cheaper, more efficient way to do some of these things that AI models have been doing, that is why we're seeing a bit of this correction here in trading today. Furthermore, we're seeing the broad tentacles of the AI trade throughout the US economy. It's not just
You know, the big tech firms, it's also the so-called picks and shovels of the AI booms. Obviously NVIDIA is the poster child for that, but companies that produce servers, that produce data centers, that produce cooling systems and power systems for data centers, nuclear power producers, even natural gas futures. Those have all been affected by the sort of like changing dynamics of this trade. So it remains to be seen and how it will play out in the next couple of days. What explains this broader reach throughout the market?
It has really gone to show how wide-reaching AI has been as a theme within Wall Street's investment thesis and the broader US economy, which is very much digitizing and very tech-focused over the last few years in particular as well. As I said earlier, a lot of these stocks, detractors from them, have been saying for some time that they've been overvalued. In some ways, the market was primed for a moment like this.
at the very least for them to be tapping the brakes to see what happens next with an extra round of earnings reports. But it could also be a more fundamental sort of reevaluation of how these things are valued. So is this the correction that some investors were expecting or does it look a little different?
That's certainly what we will sort of understand over the next few days or so. Major companies are reporting earnings over the coming weeks. They will give us some insight into that and sort of answer these questions from the C suite for sure. You know, more broadly, the bigger question is because markets have become so top heavy with a lot of these AI related stocks, if this does become this broader correction, you will see a broader reorientation of what's sort of happening on Wall Street.
even today with this sort of stock market selloff, you also saw a rally in government debt treasuries, which sort of suggests that investors are sort of fleeing for safety, at least in this particular moment in time. So it's an open question as to whether it will continue. That was Market's reporter, David Uberti. Thanks, David. Thanks for having me.
Speaking of tech, the new Trump administration is shaping up to have profound effects across the tech industry, from regulation and policy, to AI investment and development, to several high-stakes antitrust cases against tech giants Google and Meta. In a special series that kicked off today, our tech news briefing podcast will be looking at what Trump means for tech. In the first episode, WSJ Global Tech Editor Jason Dean talked about some of President Trump's policy changes that could affect Silicon Valley.
I mean, you can see some of them already. He's been very vocal about embracing policies that favor cryptocurrency and artificial intelligence. It wasn't like the Biden administration was anti-AI, but they weren't quite as fulsome in their embrace. Obviously, they were quite tough on the crypto industry.
That's a sector that venture capital firms in Silicon Valley have invested enormous sums in and have a lot at stake. I'm sure they hope that these anti-trust suits they're facing might go away or at the very least that there won't be stricter enforcement or continued strict enforcement of antitrust regulations so that there might be an ability to do more deals which could be beneficial both for the big companies and for the investors in startups who could see exits on their investments and have really
been constrained in that over the last four years.
In other news, we exclusively report that a top prosecutor has opened an internal review of the Justice Department's decision to charge hundreds of January 6 defendants with felony obstruction offenses. People familiar with the matter said that acting U.S. Attorney Ed Martin, who was appointed by President Trump, asked prosecutors in an email today to turn over files, documents, notes, emails, and other information related to the cases. Justice Department's books people had no immediate comment.
Trump pardoned virtually all of the January 6 defendants last week. A Rwanda-backed rebel group has entered the Congolese city of Goma, threatening a bloody new chapter in a 30-year conflict set off by the 1994 genocide. The city of Goma sits on Congo's border with Rwanda and is a longtime international aid hub and safe haven for civilians. Its residents have reported gunfire and heavy shelling. Rwanda's foreign ministry denied that its forces were involved in the conflict.
An extended battle for GOMA could become an early test for the Trump administration and its willingness to intervene in a war involving one of America's closest allies in Africa. And that's what's news for this Monday afternoon. Today's show was produced by Pierre Biena-May and Anthony Bansi, with supervising producer Michael Kasmidis. I'm Alex Osala for The Wall Street Journal. We'll be back with a new show tomorrow morning. Thanks for listening.
