Global stocks slide as OpenAI halt and bond rout hit markets

U.S. stocks ended lower on Monday as OpenAI's training halt fueled concerns about the artificial intelligence trade, while a continuing bond rout added pressure to markets. The AI slowdown fears extended globally, with Asian chip stocks sliding following the OpenAI pause. Meanwhile, gold fell 4% to below $4,200, pressured by a firmer dollar, the bond selloff, and bets on a Federal Reserve rate hike. In other developments, the Reserve Bank of Australia is widely expected to cut rates by 25 basis points, and former President Trump predicted oil prices will plummet "very soon" after the war ends.
