Jensen Huang has resigned as Nvidia's president, chief executive and a member of its board, effective immediately, the company announced on Thursday, Nov. 12. The board accepted the resignation on Nov. 11, according to the company's filing with the Securities and Exchange Commission.

Colette Kress, 59, an executive vice president and Nvidia's chief financial officer since 2013, is interim chief executive. She remains CFO until a permanent successor is named, the filing says. The board has begun a search that will consider internal and external candidates. Harvey C. Jones, 73, a director since 1993, was named the board's first-ever chair.

What was reported

Nvidia's statement did not address Huang's conduct, Reuters reported. Huang has admitted to an extramarital affair without naming the person, according to Reuters, which cited reports that the affair was with an executive at a Singapore-based tech company whom U.S. authorities suspect of spying for Beijing. On Nov. 8, Nvidia's board said it had begun an independent investigation after reporting that Huang had been the target of a foreign intelligence effort.

Kress is a 13-year veteran of the company who regularly communicates with Wall Street analysts and investors, the Associated Press reported. AP described Nvidia as a $4 trillion linchpin of the AI industry.

Key-person risk

Key-person risk is the exposure a company carries when its value is tied closely to one executive. It has two parts: who runs the company next, and how long it takes to settle the answer. Nvidia has handled the first part for now with an interim chief who keeps the finance job. The second part stays open while the search runs.

The first market response came on Thursday. Nvidia shares fell nearly 12 percent during the session and closed down 4.3 percent, Reuters reported. Retail investors bought about $111 million of the stock in the first half hour of trading, the biggest opening bid on record for Nvidia, according to Vanda Analytics data cited by Reuters. In after-hours trading the shares were up about 1 percent, AFP reported.

The stock trades at about 12 times expected earnings, its lowest multiple since 2012, after a steep drop from its Oct. 6 record high, according to Reuters. A lower multiple means investors are paying less for each dollar of forecast profit. It does not say whether the forecast itself will hold.

Where the move spread

The selling did not reach every chipmaker. Advanced Micro Devices rose 5.9 percent and Broadcom 5.5 percent, Reuters reported. Shares of Chinese tech companies that use Nvidia chips fell: Alibaba lost 7.1 percent in U.S. trading, and Tencent fell 2.6 percent earlier, according to Reuters.

Financing ties

The second mechanism is financing. Some companies depend on Nvidia not only as a supplier of chips but as an investor. Reuters describes the neoclouds, companies that rent out AI computing capacity, as closely tied to Nvidia, a prominent backer. That is a link, not a measured exposure; neither company has said how a change at the top of Nvidia would affect its business.

Both fell on Thursday. Nebius dropped 16.8 percent after trimming its 2026 revenue forecast, and CoreWeave lost 6.9 percent, Reuters reported.

What comes next

Nvidia reports earnings next week, according to AFP, which quoted Michael Hewson, an analyst at MCH, referring to "the numbers out next week." They will be the company's first results since Kress became interim chief executive.

Washington is also asking questions. Sen. Tim Scott, chair of the Senate Banking Committee, has asked Huang to testify voluntarily on Dec. 3, NBC News reported.

For now, the consequence for Nvidia is concrete: a company run by its finance chief on an interim basis, a board with a chair for the first time, and a stock valued at its lowest earnings multiple since 2012.
