Nvidia CEO Jensen Huang resigns, shaking AI sector and global markets

Nvidia chief executive Jensen Huang has resigned, a major event for the AI sector and global markets given the company's trillion-dollar valuation and dominance in AI chips. The resignation follows revelations of two affairs, including one with a Chinese businesswoman accused by US officials of being a spy. Nvidia is a critical lender and investor in AI firms like OpenAI and Anthropic, which use its money to buy its chips, and Huang was a key advocate for AI growth with close ties to the Trump White House. An interim CEO will lead the company while a permanent replacement is sought, and Huang has reportedly agreed to testify to Congress. The national security implications are significant, though the board sees no evidence of breaches, and stocks recovered after an initial drop. For New Zealanders, the main impact is through KiwiSaver funds exposed to Nvidia, though experts say volatility is normal and the market appears undisturbed.
