Nvidia has shed about $430bn in market value in just two trading days as allegations surrounding chief executive Jensen Huang’s relationship with an alleged Chinese spy threaten to turn a personal scandal into a major corporate and national security crisis.
The controversy intensified on Tuesday after claims emerged that Huang’s relationship with Alice Huang had helped facilitate at least $7.5bn in Nvidia chip shipments to China. Further reports said US Secretary of State Marco Rubio had previously briefed President Donald Trump about the affair.
The allegations have prompted demands for answers in Washington, calls for tighter restrictions on semiconductor exports and an investigation by Nvidia’s independent directors. The FBI is separately examining whether Huang, 63, was targeted by a foreign intelligence operation.
Republican senator Kevin Cramer, a member of the Senate Banking Committee, went further, calling for the billionaire executive to resign.
“The potential for extortion is so tremendous that something as sensitive as Nvidia chips, I just think he’s got to go,” Cramer said.
Senate Democratic leader Chuck Schumer has also demanded answers from the administration and tougher controls on chip exports to China, intensifying scrutiny of the technology supply chain at the centre of the global artificial intelligence race.
Nvidia’s independent directors have hired outside legal counsel to investigate the allegations, placing the company’s governance under fresh scrutiny.
The stakes are considerable. Huang has led Nvidia for more than three decades, transforming it from a graphics-chip manufacturer into the dominant supplier of processors used to train and operate artificial intelligence systems. Its technology powers vast data centres operated by some of the world’s biggest technology companies.
Huang owns about 3.6 per cent of Nvidia but does not hold majority voting control. His influence over the business is nevertheless unusually extensive, with dozens of senior executives reporting directly to him in a relatively flat management structure.
That concentration of authority could make the allegations particularly damaging, raising questions about how effectively the board can oversee a company whose fortunes are closely tied to its founder.
Huang has acknowledged being unfaithful to his wife, telling employees about the matter but offering no details of the relationship. He reportedly apologised to senior executives at a closed-door meeting on Monday before turning the discussion back to business. By Tuesday, he was back holding meetings at Nvidia headquarters.
China’s foreign ministry has dismissed the allegations of espionage as “groundless”.
The controversy also threatens to complicate Washington’s efforts to restrict Beijing’s access to advanced semiconductors. Successive US administrations have sought to limit exports of powerful chips to China over concerns that they could accelerate its military and artificial intelligence capabilities.
Nvidia has been caught between those restrictions and the commercial importance of the Chinese market, with export controls repeatedly reshaping which products it can sell.
The latest turmoil comes after Nvidia shares reached a record high last month, reflecting investor enthusiasm for the AI boom and the company’s position at its centre. The company has become one of the world’s most valuable listed businesses, alongside Apple and Microsoft.
The sell-off has raised concerns that the scandal could unsettle confidence in the wider technology sector, already vulnerable to questions over the sustainability of AI valuations.
Neil Wilson, UK investor strategist at Saxo, said Nvidia’s importance to the market meant the consequences could extend well beyond the company itself.
“Nvidia is huge and at the heart of the AI supply chain, so what happens to this stock matters to the rest of the market,” he said.
“There is the potential for this story to knock sentiment, which is already pretty fragile.”
For investors, the immediate question is no longer simply how quickly Nvidia can capitalise on the AI boom, but whether the company can protect its leadership, governance and access to global markets as scrutiny of its chief executive intensifies.
