Nvidia ​and Chief Executive Jensen Huang were sued on ‌Monday (November 9, 2026) in a proposed class action accusing ​them of defrauding shareholders by ⁠concealing Huang’s ties with a suspected Chinese spy.

According to a complaint filed in federal court ‌in San Jose, California, the defendants misled shareholders about Huang’s alleged affair with ‌Alice Huang, a former executive ‌of Singapore-based ⁠Megaspeed who is not related to ⁠him, and did not disclose that the matter raised national security concerns that threatened Nvidia’s reputation and ​business prospects.

The New ‌York Times reported last month about the alleged relationship, and that U.S. authorities had concluded Alice Huang was a Chinese intelligence ‌asset.

Nvidia did not immediately respond to ​a request for comment.

Jensen Huang told Nvidia’s employees he had ⁠been unfaithful to his wife, without disclosing details of the alleged relationship.

He co-founded Nvidia and ‌has led the Santa Clara, California-based company as it became the world’s most valuable chipmaker and made him one of the world’s most prominent symbols of the artificial intelligence boom.

Nvidia announced a probe into ‌the matter on Sunday (November 8, 2026). Its shares closed down ​4.3% on Monday (November 9, 2026), reducing Nvidia’s market capitalisation by approximately $190 billion. The lawsuit ⁠was filed five minutes after the U.S. stock ⁠market closed.

It is common for shareholders to sue companies after unexpected share ‌price declines. Nvidia shareholders, led by Mark Kistenmacher are seeking unspecified damages from ​the defendants.
