Nvidia and its chief executive Jensen Huang have been sued by shareholders over the spreading scandal surrounding Huang's alleged affair with a woman US authorities have concluded was a Chinese intelligence asset, according to a report by The Guardian. The legal action came the same day President Donald Trump said the FBI is investigating the matter, and one day after Nvidia shares closed down 4.3 percent, cutting roughly $190 billion from the chipmaker's market value.
What the Lawsuit Claims
The complaint was filed in federal court in San Jose, California, and accuses Nvidia and Huang of defrauding shareholders. According to The Guardian, investors allege the company and its CEO failed to disclose that Huang's alleged relationship with Alice Huang — a former executive of Singapore-based tech firm Megaspeed, who is not related to the Nvidia founder — raised national security concerns and threatened Nvidia's reputation and business prospects.
The New York Times first reported the alleged relationship last month, and reported that US authorities had concluded Alice Huang was a Chinese intelligence asset. The lawsuit was filed five minutes after the US stock market closed, underscoring how quickly the legal response followed the market turmoil.

Trump Says the FBI Is Investigating
President Trump said publicly that the FBI is "looking into" the matter, according to The Financial Times and The Associated Press. The president's comments were notable because they came alongside public expressions of support for Huang — Trump has stood by the Nvidia chief even as the investigation became public, according to SiliconANGLE.
The FBI probe adds a federal law enforcement dimension to a scandal that until now had played out mainly through press reporting and congressional channels. Three House committees had already summoned Huang to a closed-door briefing on November 18 over contacts with a Megaspeed executive whom US intelligence has tied to Chinese spy services.
A $190 Billion Single-Day Hit
Nvidia shares tumbled on Monday, closing down 4.3 percent and reducing the company's market value by approximately $190 billion, The Guardian reported. Even after the decline, Nvidia remains the world's most valuable chipmaker, with a market capitalization of roughly $4.3 trillion — a measure of how central the company has become to the AI boom, supplying the accelerators that train and run most frontier models.
The Times of London characterized the damage as a $200 billion hit and noted the scandal has moved from tabloid territory to a genuine corporate governance crisis. Analysts quoted across UK and US business press have begun asking whether Nvidia's board needs succession planning — a once-unthinkable question for a company that has, until this month, been viewed as the single most indispensable supplier of the AI era.
Nvidia's Response So Far
Nvidia announced on Sunday that it is conducting an independent investigation into reports that Huang was the "target of a foreign intelligence effort." The company did not immediately respond to a request for comment on the lawsuit, according to Reuters.
Huang, who co-founded Nvidia in 1993, has told employees he was unfaithful to his wife, without disclosing details of the alleged relationship, The Guardian reported. He has led the company as it became the world's most valuable chipmaker and one of the most prominent symbols of the artificial intelligence boom.
Why It Matters for the AI Industry
The scandal lands at a particularly sensitive moment for Washington's AI policy. Lawmakers are likely to pursue new restrictions on China's access to American AI chips following the spy allegations, Reuters reported, and the House briefing scheduled for November 18 could produce the first public testimony on how a foreign intelligence service allegedly approached the most important company in AI.
The shareholder suit also tests a novel legal theory: that a CEO's personal conduct — and a board's failure to disclose its national security implications — can constitute securities fraud. If the case survives a motion to dismiss, it would broaden the boundaries of what disclosure obligations apply to founder-led AI companies at the center of geopolitics.
For now, the practical questions are narrower: whether Nvidia's independent investigation substantiates or disputes the intelligence community's conclusions, whether the November 18 briefing goes ahead as scheduled, and whether further institutional investors join the San Jose action. Each answer could move a stock that indexes not just Nvidia's fortunes, but the market's confidence in AI infrastructure spending as a whole.
The company that supplies the computing power behind nearly every major AI model is now defending its governance in three arenas at once — a federal courtroom in San Jose, congressional hearing rooms in Washington, and the court of public opinion. How those proceedings unfold over the coming weeks will shape both Nvidia's leadership and the regulatory environment for the entire AI hardware industry.
