Nvidia and chief executive Jensen Huang were sued on 9 November in the US District Court for the Northern District of California over disclosures to shareholders about Huang’s dealings with a Singapore company and his alleged relationship with one of its executives. The proposed class action, brought by investor Mark Kistenmacher, accuses them of concealing information that could affect Nvidia’s reputation and business prospects, PPC Land reported. The case is numbered 5:26-cv-13448.
Key points
- The complaint alleges Nvidia and Huang misled investors about his dealings with Megaspeed and his relationship with one of its former executives.
- The proposed class covers purchasers of Nvidia securities from 9 October 2025 to 8 November 2026. Kistenmacher seeks unspecified damages.
- Nvidia’s board announced an independent investigation on 8 November. It said it had no reason to believe national security or company secrets were compromised.
Kistenmacher seeks damages for Nvidia investors
Kistenmacher brought the case on behalf of people and entities that acquired Nvidia’s publicly traded securities between 9 October 2025 and 8 November 2026. The defendants are Nvidia and Huang. Kistenmacher is represented by Laurence M. Rosen of The Rosen Law Firm in Los Angeles. He seeks damages for the proposed class, although the amount has not been set out, CNA reported.
The complaint alleges that investors were misled when Huang’s dealings with Singapore-based Megaspeed were presented as routine while his alleged relationship with Alice Huang, a former Megaspeed executive who is not related to him, remained undisclosed. It further alleges that the relationship raised national security concerns with consequences for Nvidia’s reputation and business prospects. Those are the investor’s allegations, not findings by the court.
The suit was filed five minutes after the US stock market closed on 9 November, according to CNA. That timing separates the complaint from the day’s trading. Nvidia’s board had announced its investigation the previous day, and the company’s shares fell during the 9 November session. The investor’s claim concerns what shareholders were told during the proposed class period, rather than any disclosure made in the lawsuit itself.
Megaspeed dealings form part of the complaint
Megaspeed purchases Nvidia AI chips and has been investigated over suspicions that it helped Chinese companies obtain processors subject to US export restrictions. Nvidia’s dealings with the company had already become a public issue: AI Affairs reported Huang’s defence of those dealings after an earlier spying report. The complaint places his account of that business relationship alongside the alleged personal relationship with a Megaspeed executive.
The New York Times reported in October that US authorities had concluded Alice Huang was a Chinese intelligence asset, according to CNA. Jensen Huang told Nvidia employees he had been unfaithful to his wife. The employee message did not give details of the alleged relationship. The complaint alleges that the relationship raised national security concerns and that Nvidia and Huang misled shareholders about it.
China rejects the espionage allegation. Foreign Ministry spokesperson Guo Jiakun called the account of a suspected Chinese spy “entirely baseless vilification and smearing”, The Times of India reported. The government’s rejection concerns the suspected intelligence operation. The shareholder case asks a different question: whether Nvidia and its chief executive misled investors about a matter the complaint says threatened the company.
Nvidia’s board investigates after 8 November
Nvidia’s board announced on 8 November that a committee of independent directors, assisted by outside independent counsel, would oversee an investigation into reports that Huang had been the target of a foreign intelligence effort. As AI Affairs reported when the inquiry began, the board took responsibility for examining the matter rather than leaving it to Huang. The board said Huang supported the review and had committed to cooperating with it.
The board said it had “no reason to believe that either national security or Nvidia secrets were compromised”, PPC Land reported. It also said the inquiry would examine all available information. That assessment addresses whether a compromise occurred. Kistenmacher’s complaint concerns the information given to investors before the board opened its inquiry.
Nvidia shares closed down 4.3 per cent on 9 November, reducing its market capitalisation by approximately US$190 billion. PPC Land gave the decline as 4.27 per cent, or US$7.97, to a close of US$178.67. The complaint follows that fall, but was filed after trading ended. AI Affairs had previously reported a 3.4% share decline while the board investigated Huang.
The board set no deadline for its investigation, PPC Land reported. It said it would provide further updates as appropriate.
