Nvidia Stock Drops $250bn as Trump Confirms FBI Probe Into CEO’s Spy Affair

Nvidia is one of the world’s most valuable companies. It makes computer chips that power artificial intelligence. Its chief executive, Jensen Huang, is now part of a major story. US President Donald Trump says the FBI is looking into Huang’s relationship with a woman accused of spying for China.

Nvidia’s stock fell sharply after the news broke. Shares dropped more than 4% on Monday. That wiped out about $250 billion (£190bn) in company value.

What Trump Said

Trump spoke to reporters at the White House on Monday. He said he had talked to Huang earlier that day.

“I asked him that question. Did you have any idea she was a spy?” Trump said. “He said, ‘I had no idea she was a spy.’ And I really believe him.”

Trump said the FBI is looking into the matter. He did not share more details. He did not say when the investigation began. Trump also said he believes Huang “will be in good shape.” He said he had been hearing about the issue “not too long ago.”

Who Is the Alleged Spy

The woman is known as Alice Huang, also called Huang Le. She is not related to Jensen Huang.

US intelligence officials believe she worked for China’s Ministry of State Security, according to a New York Times report. She held a senior role at Megaspeed, a data center company based in Singapore. Reports say Jensen Huang had an affair with her. The two reportedly met in person during trips to Taiwan in 2024 and 2025.
