AI stock selloff spreads globally, but broader market gains keep Wall Street near records

AI stocks continued falling Thursday, but gains across the broader market kept U.S. indexes near record highs. The S&P 500 was flat, the Nasdaq fell 0.4%, and the Dow rose 440 points as most stocks climbed. The AI selloff, which began Wednesday, spread globally before returning to Wall Street, hitting South Korea's Kospi down 7.6% and Japan's Nikkei down 4.9%. Rising bond yields have raised concerns about debt loads at AI companies like CoreWeave, which fell 5.2%, and Nvidia, down 1.9%. Strong profit reports from Taiwan Semiconductor and ASML failed to boost AI stocks, while non-AI firms like Marsh & McLennan rose 6.4%. Treasury yields fell to 5.07% despite stronger-than-expected U.S. economic data, and European indexes mostly gained.
