U.S. Markets Recover Mixedly After AI Regulation Fears Spark Crash

U.S. equity markets experienced extreme volatility during the first week of November 2026, characterized by a severe crash on Thursday following a Wednesday surge. The S&P 500 fell 4.4%, the Nasdaq Composite tumbled 5.5%, and the Dow Jones Industrial Average dropped 3.4%. The downturn was driven by investor fears that the Democratic Party, newly empowered at state and federal levels, might regulate artificial intelligence development and slow the buildout of data centers. Nvidia fell 9.3%, contributing to a more than 12% drop in the Nasdaq semiconductor index.

Markets ended mixed on Friday, November 6, as technology stocks rebounded through bargain hunting in AI and semiconductor shares. The Nasdaq Composite jumped 1.1% to 24,579.42 and the S&P 500 rose 0.3% to 7,376.86, while the Dow Jones Industrial Average fell 0.5% to 51,285.73. This recovery occurred amid a broader global slump, including a nearly 6% plunge in Japan's Nikkei 225.

Economic data provided a backdrop of stability. The U.S. Bureau of Labor Statistics reported that 165,000 non-farm payrolls were added in October with an unemployment rate of 4.1%. Additionally, the University of Michigan reported an unexpected rise in consumer sentiment to 51.0. President Donald Trump blamed Democrats for the market turmoil, while analysts suggested that long-term company earnings should remain stable enough to drive the market higher over the next year.
