Stock market today: Dow, S&P 500, Nasdaq futures waver as leaked Anthropic IPO details raise alarm about AI risks

US stock futures wavered as a leaked Anthropic (ANTH.PVT) IPO prospectus and scrapped OpenAI (OPAI.PVT) next-generation model raised more questions about AI safety, while geopolitical tensions continued to support higher oil and bond prices. Futures on the Dow Jones Industrial Average (YM=F) and the S&P 500 (ES=F) slipped by 0.1%, extending Monday's losses. Contracts for the Nasdaq-100 (NQ=F) edged higher. AMD (AMD) stock was little changed after the Lisa Su-led company acquired Fei-Fei Li's AI model startup World Labs for $8.2 billion in a deal viewed as a talent and AI insights play.
