Nvidia’s CEO, Jensen Huang, has resigned following allegations of an extramarital affair with a Chinese businesswoman linked to intelligence activities. The company announced the resignation on Thursday, citing national security concerns. Huang, who led Nvidia for over a decade, is accused of having at least two affairs, with one partner reportedly acting as a spy for Beijing.

The affair came to light after Singapore authorities banned Alice Huang, the alleged spy, from the country over her involvement with Megaspeed, a Singapore-based AI data center company tied to China. Megaspeed has purchased billions in chips from Nvidia. The situation prompted a probe into Huang’s conduct and its implications for U.S. National security.

Nvidia’s board has appointed Colette Kress, the company’s chief financial officer, as interim CEO. Kress has held key roles at Nvidia for over a decade, including executive vice president. Her appointment marks a significant shift in leadership, as the company faces scrutiny over its ties to Chinese entities.

This is not the first time Huang has been embroiled in controversy. Previous reports had already raised concerns about his personal conduct. The resignation has led to a sharp decline in Nvidia’s stock value, with the company’s market capitalization dropping below $4 trillion for the first time since 2025.

Huang’s resignation follows a pattern of leadership challenges for Nvidia, which has become a dominant force in artificial intelligence and chip manufacturing. The affair allegations have intensified pressure on the company, as it navigates both personal and geopolitical issues. The full extent of the implications remains under investigation.
