Nvidia has no publicly designated number two, and this week that gap became a live risk. Chief executive Jensen Huang admitted to an affair, and Nvidia's board announced an investigation into whether Huang was the target of a "foreign intelligence effort." Suddenly, the question of who could replace the founder is no longer theoretical.

Nvidia moved quickly to close the door. In a statement on Sunday, the company said: "Jensen is committed to continuing to lead Nvidia as CEO without interruption." The company did not immediately respond to a further request for comment. A corporate assurance, however, is not a governance plan — and what Nvidia has not said is who would run the company if the assurance fails.

What does the succession picture actually look like?

Huang is famously resistant to hierarchy. He runs an unusually flat structure with roughly 60 direct reports, and no executive has been publicly positioned as an heir.

Daniel Newman, CEO of The Futurum Group, put the problem bluntly: "That works beautifully while he's in the seat, but it means nobody has been groomed, tested, or publicly positioned as the heir."

Huang does not hold controlling voting power, but he owns about 3.6% of Nvidia. Brad Gastwirth, global head of research at Circular Technology, said Huang would likely "have considerable input into succession unless the investigation uncovers serious wrongdoing."

"Jensen's combination of technical expertise, strategic vision, and industry relationships is nearly impossible to replicate," Gastwirth said. That claim is hard to test — but it is widely held among the analysts and former employees weighing the field.

Who are the internal candidates?

The names circulating point to a bench that is thin on visibility, if not on tenure:

• Colette Kress, chief financial officer, is the company's only other highly visible executive, according to Gil Luria, an analyst at DA Davidson. She could take over as interim CEO if Huang stepped aside. Kress has spent 13 years at Nvidia, after finance roles at Cisco and Microsoft. She lacks the engineering background central to Huang's leadership.
• Ian Buck, vice president of accelerated computing, heads Nvidia's data center and computing businesses after 22 years at the company. He helped develop CUDA (the chip software layer underpinning Nvidia's dominance in AI). A former employee said: "He's already running the group that is generating virtually all the revenues."
• Madison Huang, the CEO's daughter and senior director of product marketing for physical AI, has been asserting greater authority across Nvidia's businesses, one former employee said — a move they believe could position her for a larger leadership role. Her brother, Spencer, also works at Nvidia, raising questions about whether leadership could stay in the family.

A second former employee stressed culture over résumé: "Ideally it has to be someone from the company who's lived the values and the culture."

Could Nvidia hire from outside?

Some observers have floated executives from other major technology companies, including Google Cloud CEO Thomas Kurian and Amazon Web Services CEO Matt Garman. Both run vast cloud computing businesses that buy heavily from Nvidia and invest heavily in AI infrastructure, giving them firsthand knowledge of the customers and technologies driving its growth. Neither has been linked to any actual process — the board's investigation is the only formal step that exists.

What does this change for Nvidia?

For now, probably nothing: Huang has repeatedly said he intends to work as long as possible, and his departure appears unlikely. The risk is conditional. If the board's investigation surfaces serious wrongdoing, Huang loses his presumed influence over succession — and Nvidia loses a leader no successor on the list can clearly match.

Gastwirth's assessment is stark: "I think it would be one of the worst things that could happen to Nvidia. The company would continue operating, but I would question whether it could maintain the same pace of innovation and execution."

The company has given investors one sentence of reassurance. It has not given them a plan.
