In 2024, when asked what advice he would have for aspiring Stanford entrepreneurs, Nvidia CEO Jensen Huang repeated one of his signature lines.

“I wish upon you ample doses of pain and suffering,” he said on stage at a summit (opens in new tab) for the Stanford Institute for Economic Policy Research.

Greatness, he said, comes from character. And character is formed through suffering. “Unfortunately, resilience matters in success,” he said.

Huang, 63, is in the throes of his own high-profile, character-building event, but one that could bring this chapter of his career to a halt at its peak. On Sunday, he admitted to an affair with a suspected Chinese intelligence asset, and on Wednesday The New York Times (opens in new tab) reported he’d been in another extramarital relationship, this time with a health care executive at his own company who reports to him.

Nvidia’s board of directors is expected to meet and discuss Huang’s fate this week. If it decides to let him go, it would end his 33-year tenure at the chipmaker he cofounded and helped grow into one of the most valuable companies in the world, and a linchpin of the AI boom.

Huang’s potential fall is remarkable, and captures a pivotal moment in Silicon Valley. Money and economic influence are being consolidated among a handful of hundred-billion- and trillion-dollar AI companies, all racing to help build a potentially society-altering technology ahead of rivals in countries such as China. The heads of the biggest AI players have become public figures on their own, their brands melding with the companies they run.
