Two of the world’s most valuable companies have changed bosses in recent months. They could hardly have done so more differently. At Apple, Tim Cook made way for John Ternus in September under what the iPhone-maker called a “long-term succession plan”. Nvidia’s succession plan lasted four days. Jensen Huang, the chip giant’s only boss in its 33-year history, never intended to leave. On 8 November, he confessed to an affair; on 12 November, after further revelations about his private life, he resigned.
The job has fallen, for now, to Colette Kress, Nvidia’s finance chief since 2013, who has been named interim chief executive. She was never coached for the top job, and will need to learn fast. Since news of the scandal broke, Nvidia’s shares have lost about 20% of their value. Besides calming investors, she will need to shore up suppliers, mend fences with Washington and hold together the vast web of financing schemes and partnerships that has fuelled Nvidia’s breakneck growth.
Ms Kress inherits one of the most formidable money-making machines in corporate history. Two-thirds of the world’s artificial-intelligence computing power runs on Nvidia’s chips. Its gross margins hover around 75%, against 55% at AMD, a rival chip designer. This financial year analysts expect it to bring in more than $400bn in revenue, nearly double last year’s total. And it is sitting on around $100bn in cash and liquid financial instruments.
Ms Kress’s first test will come on 17 November, when Nvidia reports its latest earnings. A blowout quarter would soothe nerves. But investors will also want assurances that Nvidia can still achieve the 70% revenue growth it has promised for next year. She will need to convince them that the upheaval at the top will not distract the company at a time when it faces formidable rivals, including AMD and cloud giants such as Google and Amazon, which now design their own AI chips.

Next is the chip giant’s intricate supply chain. Nvidia says that it cannot fill all the demand because of supply-chain bottlenecks. That makes the launch of Vera Rubin, its next generation of AI systems, especially delicate. Reports have suggested that manufacturing problems are holding up production of the higher-end variant.
Ensuring that its products are delivered on time requires working with suppliers such as TSMC, the Taiwanese firm that manufactures its chips, and memory-makers such as SK Hynix of South Korea. Mr Huang excelled at this, running the relationships as much by charm as by contract. Nvidia has signed long-term deals with many of its suppliers, committing hundreds of billions of dollars to them through 2029. But they, too, will want reassurance that the lofty growth targets behind the orders still hold.
Then there is Washington. Mr Huang was one of Donald Trump’s favourite businessmen, and used his access to lobby hard for looser curbs on selling chips to China, often clashing with hawks in Congress. The scandal has left Nvidia’s standing in the capital badly bruised.

On 18 November, a day after the earnings call, Mr Huang has been asked to appear at a closed-door congressional briefing to answer questions about his relationship with Alice Huang, an executive at Megaspeed, a Singaporean customer of Nvidia, whom American officials reportedly suspect of being a Chinese agent.
Democrats, who take control of Congress in January, may add more pressure. One employee concedes that Mr Huang’s combative style in Washington made Nvidia enemies, and that it will need to work with policymakers rather than against them. Ms Kress will need to change course.
The hardest task of all may be keeping Nvidia at the centre of the AI economy. Mr Huang’s aggressive dealmaking has made the company the AI-infrastructure boom’s most important player, and boosted demand for its chips.
