Financial Markets Wall Street

A drop for Nvidia’s stock is pulling the U.S. market lower, threatening to upend the AI boom that carried Wall Street to records in recent years. The S&P 500 fell 0.6% Thursday. The Nasdaq composite dropped 0.9%, but the Dow Jones Industrial Average dipped only a modest 15 points. Nvidia tumbled nearly 10% after Jensen Huang, its co-founder and face of the brand, resigned as CEO. Other stocks in the AI industry also fell, though some of Nvidia’s rival chip companies rose and limited the overall market's losses. Oil prices swung after President Donald Trump said he's no longer interested in a deal with Iran.
