Stock market today: Dow, S&P 500, Nasdaq drift lower as tech slides

US stock futures fell on Tuesday morning as the AI trade, earnings, and an upcoming Fed decision remained in focus. Contracts for the Nasdaq-100 (NQ=F) fell 0.3%, while futures on the Dow Jones Industrial Average (YM=F) moved just above the flatline. Those on the S&P 500 (ES=F) drifted lower, following Monday's gains. AI stocks continued to benefit from revived enthusiasm after Anthropic's (ANTH.PVT) IPO investor prospectus, which the company filed publicly on Monday, highlighted the promise — and risks — of artificial intelligence. In Asia, the resurgent AI trade helped lift South Korean chip stocks and the KOSPI (^KS11) index, pointing to a solid opening for US tech stocks.
