US stock futures extended losses after Jensen Huang resigned as Nvidia’s president and CEO, injecting fresh uncertainty into the global AI sector. S&P 500 futures fell 0.8%, Nasdaq 100 contracts dropped more than 1%, and Dow futures also edged lower. Nvidia shares slumped 10% in premarket trading after CFO Colette Kress was appointed interim CEO, following a board meeting that culminated in Huang’s departure over his links to a Megaspeed executive widely suspected of being a Chinese spy. Under Huang’s leadership, Nvidia’s market capitalization swelled to nearly $6 trillion, and he drove deal-making across the AI supply chain, making his exit a shock to the broader technology industry. AMD and Broadcom traded higher, but AI infrastructure names sold off sharply. Nebius also fell nearly 10% after postponing part of its data center capacity expansion. Elsewhere, several sectors provided some relief, rebounding after Tuesday’s hotter-than-expected CPI print reinforced expectations for additional Federal Reserve rate hikes in the current tightening cycle.
