SAN JOSE, California — A shareholder sued Nvidia and chief executive Jensen Huang on Monday in the U.S. District Court for the Northern District of California, accusing the company of misleading investors about Huang's relationship with a woman American officials suspect of working for Chinese intelligence.
The proposed securities class action, filed by retail investor Mark Kistenmacher, seeks unspecified damages and a jury trial. It covers investors who bought Nvidia securities between October 9, 2025, and November 8, 2026.

What the Nvidia Shareholder Lawsuit Alleges
The complaint says Nvidia made materially false or misleading statements and failed to disclose adverse facts. It argues Huang's affair with a suspected Chinese spy, who also holds a role at Megaspeed — a Singapore-based company suspected of helping China evade export controls — made Nvidia's statements about Megaspeed false, raised national security concerns that threatened its reputation and prospects, and left its positive statements without a reasonable basis.
The complaint also cites three company statements it calls false or misleading for omitting the affair and the national security concerns. The filing came a day after Nvidia's board opened an independent investigation and Huang admitted the affair in a staff memo.
Alice Huang, a former Megaspeed executive, is at the centre of the case; the two Huangs are not related. American officials suspect she passed information to Beijing and helped move advanced AI chips into China, breaching U.S. export controls. Those claims rest on unnamed U.S. officials, not court findings. China has denied the espionage allegations.
How Nvidia Shares Reacted to the Lawsuit
Nvidia shares fell $7.97, or 4.27 percent, to close at $178.67 on Monday, November 9, erasing about $190 billion in market value. The wider market rallied the same day, with the S&P 500 up 2.35 percent and the Dow up 2.15 percent. The slide also cost Nvidia its place as the world's second-most valuable company, with Microsoft moving ahead of it.
Huang admitted the relationship on Sunday, November 8, when the board opened its investigation. The lawsuit was filed five minutes after the market closed on Monday.

What Happens Next for Nvidia and Huang
Four other securities firms say they are examining whether Nvidia misled investors. Their reviews do not amount to lawsuits. President Donald Trump said the Federal Bureau of Investigation is looking into the matter; the bureau has not announced an investigation or any charges.
The case now moves through the federal court in San Jose, where a judge must decide on class certification and a lead plaintiff. Away from the courtroom, Nvidia's product work continues — it unveiled its GR00T 2 robot model on November 9.
Nvidia reports third-quarter results on November 17, and three House committee chairmen want a closed-door briefing with Huang on November 18. The next date after that is the January 8, 2027 lead plaintiff deadline.
