Nvidia CEO's resignation casts shadow over AI boom

Nvidia CEO Jensen Huang resigned Thursday following reports of extramarital affairs, including with a suspected Chinese spy, sending shockwaves through the tech industry and raising questions about the future of the AI boom he championed. Huang was the public face of Nvidia, which dominates the market for AI training chips and trades with Apple as Wall Street's most valuable company. Rivals like Broadcom, Intel, and AMD saw shares rise as investors anticipated customers diversifying suppliers, potentially turning Nvidia's monopoly into a competitive market. Analysts say the fallout could strengthen the broader AI industry by creating more choice, though Nvidia's losses may outweigh rivals' gains. The scandal also raises prospects of tighter US export controls, potentially benefiting Chinese chipmaker Huawei, and adds uncertainty ahead of AI firms' planned public debuts.
