U.S. equity futures declined early Monday as investors weighed concerns over artificial intelligence security, OpenAI’s decision not to pursue a 2026 initial public offering, and rising oil prices linked to disruptions in the Middle East. S&P 500 futures fell 0.5%, Nasdaq-100 futures dropped 1.2% and Dow futures slipped about 50 points, or 0.1%. Anthropic CEO Dario Amodei urged technology companies to slow development of advanced AI systems because of security risks, while OpenAI chief executive Sam Altman endorsed pacing frontier AI and said a 2026 IPO would be ill-advised. SoftBank Group shares fell more than 11% in Tokyo after the announcement. Crude oil rose more than 2% after Saudi Arabia’s pipeline closure and Houthi attacks affecting maritime trade, with U.S. crude having already moved above $100 a barrel last week. The Federal Reserve’s policy meeting is approaching, and futures markets priced an 86% probability of an interest-rate increase. The Dow had fallen 1.6% in the previous week, its weakest weekly performance since March, while the S&P 500 and Nasdaq Composite each declined less than 1%.
