Nvidia's CEO probe shows how much markets lean on one man (opens the source in a new tab)

- Nvidia shares slid after reports that a woman suspected of being a Chinese intelligence asset had grown close to CEO Jensen Huang, who has acknowledged an affair. An independent board committee is investigating; China calls the spy claim unsubstantiated.
- Bloomberg explains the market stakes: every big decision runs through Huang, no successor is designated, and Nvidia's weight in the S&P 500, about 8% for much of two years, has slipped below Apple's.
- Wired says the AI industry is reeling too. Nvidia controls about 90% of chips for training frontier models, so Huang decides who gets them, and it has invested in customers such as OpenAI and Anthropic.
Why it matters Index funds tie millions of savers to Nvidia, and AI labs depend on Huang for scarce chips and funding. When one founder's private life can move both, the AI boom's single point of failure is a person, not a chip.
Other side The board reportedly wants to keep Huang, and Nvidia's lead rests on years of investment and yearly chip launches, not one man's diary. A dip driven by scandal rather than sales may not last; rivals, China and doubts over AI spending are the bigger tests.
