U.S. Stock Futures Point Lower as AI Debt Concerns and Oil Surge Weigh on Markets

U.S. stock futures fell Tuesday, pointing to a lower open as volatility extends into a second session. S&P 500 futures were down 0.4%, with technology stocks facing renewed selling pressure after leading Monday's rebound. Goldman Sachs projects $420 billion in global hyperscaler debt issuance for 2027, a more than 60% increase from its 2026 estimate, fueling concerns about AI-related borrowing. Meanwhile, U.S. crude oil futures jumped more than 1% to $104.97 a barrel after Houthi attacks on Saudi infrastructure and reports of vessel attacks in the Gulf sent prices up as much as 6.6% earlier. Trading may stay subdued ahead of earnings from SpaceX (SPCA) Tuesday night and Tesla (TSLA) and Meta (META) later this week. On Monday, the Nasdaq rose 1.1% to 26,430.89, the S&P 500 gained 0.4% to 7,690.73, and the Dow slipped 0.1% to 51,966.03. Asian markets fell, with South Korea's Kospi down 3.7%, while European indexes also declined.
