NEW YORK (AP) — A brutal sell-off swept through Wall Street, led by stocks tied to the buildout of AI data centers. The S&P 500 fell 4.4% Thursday for its worst drop since President Donald Trump shook markets worldwide in April 2025 with his “Liberation Day” tariffs. The wipeout more than erased the market’s gain from the day before, which was its best in three months. The Dow Jones Industrial Average dropped more than 1,800 points, and the Nasdaq composite tumbled 5.5%. AI stocks worldwide felt pressure as worries rise about possible moratoriums on data centers following Democratic victories in the U.S. midterm elections.

NEW YORK (AP) — Brutal drops for stocks tied to the buildout of AI data centers accelerated Thursday and more than erased the U.S. market’s gain from the day before, which was its best in three months.
The S&P 500 fell 3.6% and was on track for its worst day since President Donald Trump shook markets worldwide in April 2025 with his “Liberation Day” tariffs. The Dow Jones Industrial Average was down 1,533 points, or 2.9%, with an hour remaining in trading, while the Nasdaq composite was 4.5% lower.
The Nasdaq, which is full of AI-related and other tech stocks, sank 11% below its all-time high set last month. Stock geeks call a loss of more than 10% a “correction.”
Stock markets around the world felt pressure from continued drops for companies that had benefited from the boom in the artificial-intelligence technology industry, and South Korea’s Kospi index tumbled 5.3%. Such stocks have been swinging for months on worries that the construction of further AI data centers may slow because of how expensive it’s become to borrow money. Critics also said AI stock prices had shot too high and were in a bubble.
Tuesday’s U.S. midterm elections added another challenge. The nationwide victories by Democrats raised the possibility that governments could force pauses in construction of more data centers. Voters across political parties say they’re wary about AI and don’t like the increases to power bills caused by data centers.
Any slowdown in AI data center construction would mean fewer purchases of AI chips, not to mention electricity and other products and services that are getting vacuumed up in the AI frenzy, which is driving much of the U.S. economy’s growth.
Nvidia, the chip company that quickly became the face of the AI boom, fell 8% and was by far the heaviest weight on the S&P 500, a day after dropping 3.2%.
Advanced Micro Devices tumbled 14%. CoreWeave, a company that rents access to AI chips to customers over the cloud, fell 8.9%. GE Vernova, which has been helping to power data centers, sank 6.9%.
AI chip stocks are some of Wall Street’s most influential because they’ve become some of the largest. A 1% move for Nvidia, for example, has more effect on the S&P 500 than a 1% move for nearly any other U.S. stock.
The losses were broad after morning gains for the majority of stocks on Wall Street quickly evaporated.
Among the handful of winners was AppLovin, which jumped 29.4% after reporting both revenue and profit that topped analysts’ expectations. The marketing platform also approved a program to send up to $3.2 billion to its investors by buying back its own stock, bringing the program’s total potential value to $3.6 billion.
Tapestry rallied 7.4% after the company behind the Coach and Kate Spade brands likewise delivered a stronger profit than expected. It also raised its forecasts for revenue and earnings this fiscal year.
Stock prices tend to follow where corporate profits and interest rates go over the long term, depending on them much more than on who controls what in Washington.
In other financial markets, the initial knee-jerk reaction to the U.S. midterm election results faded a bit. The price of a barrel of Brent crude oil rose 3.9% to $98.29 and recovered a chunk of its nearly 9% drop from the day before. Uncertainty still reigns about what will happen in the war with Iran and when the global energy industry can return to normal.
In the bond market, Treasury yields continued to tumble. The yield on the 10-year Treasury fell to 4.83% from 4.90% late Wednesday. It had been at 4.95% on election night and above 5.30% last month. That could be a signal that investors are herding into U.S. Treasury bonds in search of something that’s safer to own than stocks.
The drop came despite some encouraging reports on the U.S. economy. Fewer U.S. workers applied for unemployment benefits last week. A separate report, meanwhile, suggested overall productivity for U.S. workers improved by more during the summer than economists expected. That could help the economy grow without adding pressure to the nation’s high inflation.
In stock markets abroad, indexes were mixed in Europe and Asia. Besides South Korea, Japan’s Nikkei 225 also felt the sting of drops for tech and AI-related stocks and sank 1.8%.
London’s FTSE 100 dipped 0.4% after the Bank of England increased its main interest rate for the first time in three years to help limit high inflation.
The bank said its next moves on interest rates largely hinge on what happens with the Iran war, which sent oil prices and inflation higher worldwide.
“We’ve seen encouraging news in the past 48 hours,” Bank Gov. Andrew Bailey said at a press briefing. “The best thing that can happen is to resolve the conflict in the Middle East; there’s no question about it.”
