US intelligence believes Nvidia CEO Jensen Huang had a romantic relationship with an alleged Chinese spy, prompting congressional scrutiny.

The woman, Alice Huang, is an executive at Megaspeed International, a Singapore-based Nvidia customer. US officials say China's Ministry of State Security recruited her to spy on Jensen Huang. The alleged goal was to gather intelligence on Nvidia and convince him to lobby for chip exports to China. The assessment appears in an early 2026 memo based on a year of surveillance.

The chairs of three House committees have summoned Jensen Huang for a closed-door briefing on Nov. 18. The committees are Foreign Affairs, Intelligence, and the Select Committee on the Chinese Communist Party. They want to determine how much US national security has been placed at risk. The briefing falls one day after Nvidia reports quarterly earnings.

President Donald Trump was briefed on the allegations last year but did not act, according to the New York Times. The memo was also shown to a small circle of officials before Trump's May trip to China. A meeting between Trump and tech leaders scheduled for Friday was postponed by one week.

Nvidia has denied that the relationship was anything but a typical business contact. The company says Jensen Huang meets thousands of client executives each year and that no sensitive information was shared. An internal investigation found no evidence of wrongdoing. The Chinese government has denied recruiting Alice Huang.

Megaspeed is under US investigation for allegedly smuggling advanced Nvidia chips to China. The company is accused of violating export controls. Jensen Huang has personally lobbied Trump to ease restrictions on selling H200 AI chips to Chinese buyers.

Photos circulating online show Jensen Huang with Alice Huang. The images include a 2024 photo from a bar in Taipei. The two are not related despite sharing a surname. Sen. Chris Coons, a Democrat from Delaware, posted on X: "Congress will investigate and get answers."
