Nvidia Shareholders Sue Company and Jensen Huang Over Affair Disclosure
A proposed shareholder class action accuses Nvidia and CEO Jensen Huang of misleading investors by not disclosing that Huang’s affair with a former Megaspeed executive raised national security concerns. Investor Mark Kistenmacher filed the suit Monday in federal court in California, days after Nvidia lost roughly $190 billion in market value.
What the lawsuit alleges
The complaint names Nvidia and Huang as defendants and seeks class status for investors who bought Nvidia shares during the period the alleged misleading statements were in effect. According to UPI, it claims Nvidia and Huang failed to disclose that his relationship with Alice Huang, a former executive at Singapore-based Megaspeed, carried national security risks that could hurt the company’s “reputation and business prospects.”
The suit also alleges Nvidia made misleading statements about its business relationship with Megaspeed, a company that has reportedly been investigated over whether it diverted Nvidia chips to China in violation of US export restrictions. Alice Huang is not related to Jensen Huang, despite the shared surname.

How this followed the affair disclosure
Nvidia’s board opened an independent investigation on November 8 into Huang’s ties to a suspected Chinese intelligence effort, hours after Huang admitted in a company-wide message to an extramarital affair without naming the other person. That followed an earlier US intelligence memo report alleging China had recruited Alice Huang to seek information from the Nvidia CEO.
Huang’s apology letter, posted on Nvidia’s own website, addressed his wife, family and the company but did not identify the person he had the affair with. Nvidia’s board at the time said it had found no indication that national security had been compromised, a position the new lawsuit directly disputes.
Nvidia shares fell 4.3% on Monday, November 9, cutting about $190 billion from the company’s market value, UPI reported. Shares continued to slide Tuesday, closing down roughly 5.5% from before the news broke, according to the Korea Times.
The Megaspeed export-control question
Megaspeed is a Singapore-based company where Alice Huang previously worked as an executive. The lawsuit cites reports that regulators have examined whether Megaspeed diverted Nvidia chips to buyers in China, which would run against US export restrictions on advanced semiconductors to the country.
Nvidia has described its business dealings with Megaspeed as a routine commercial relationship. The complaint argues that framing was misleading once the personal connection between Huang and Alice Huang became relevant to assessing the company’s China-related risk disclosures.
What Trump and the FBI have said
US President Donald Trump said Monday that Huang “had no idea” Alice Huang was a spy, and called him “a very honorable man.” Trump said Tuesday that the FBI is also investigating Nvidia and Huang over the matter, per UPI’s reporting.
The New York Times has reported that US officials told Trump about the Nvidia-Megaspeed connection shortly before his May trip to Beijing, which Huang also joined, making this at least the second time in seven months Trump was told of the intelligence concerns. China has denied the espionage reports.
How markets reacted
Nvidia is among the world’s most valuable companies by market capitalisation, so a single-day drop of 4.3% translated into tens of billions of dollars in lost shareholder value. The stock’s continued slide into Tuesday, down about 5.5% from before the reports broke, suggests investors have not yet priced in how the board investigation, the lawsuit and the reported FBI inquiry will be resolved.
The complaint argues that had investors known about the undisclosed risks earlier, they would not have bought Nvidia shares “at the artificially inflated prices that they did, or at all.” That is the core legal theory behind the proposed class action: that the stock price baked in information the company had not disclosed.
What happens next
The lawsuit is at an early stage and none of its allegations have been established in court. Nvidia’s board-ordered investigation and the reported FBI inquiry continue separately from the shareholder case. Huang remains in his role as CEO while the investigations proceed.
