Nvidia has pushed back on a New York Times report that US intelligence agencies concluded a businesswoman with a close relationship to CEO Jensen Huang was a Chinese intelligence asset feeding information to Beijing.

Getting into it: According to the Times, Alice Huang, also known as Huang Le, a Chinese citizen and former top executive at Singapore-based data center company Megaspeed, was in contact with Jensen Huang, which US agencies discovered while electronically surveilling her. Megaspeed was already suspected of helping get Nvidia’s advanced AI chips into China.

Trump was briefed on the findings roughly a year ago but didn’t act, reluctant to get in the way of Nvidia’s chip sales and the trade relationship with China, and Jensen Huang was never given a “defensive briefing,” a heads-up the government can give Americans when a foreign intelligence service is coming after them. Officials first believed he didn’t know about her alleged role, though some senior administration officials now doubt that.

The surveillance is ongoing, and companies tied to Alice Huang kept buying Nvidia chips this year, including a Malaysian sister company that bought at least $4.8 billion worth of AI equipment with Nvidia chips over less than two years. The Justice Department took over the Commerce Department’s investigation into Megaspeed this year.

In a statement, Nvidia said the allegations that Megaspeed diverted chips to China were “thoroughly investigated and debunked last year,” and that customers like Megaspeed only get ordinary business information, not trade secrets or anything tied to national security. Jensen Huang told Bloomberg that Nvidia had counted every one of Megaspeed’s chips, that Alice Huang is no longer with the company, and that the US government never warned him about her.

“Our relationship, our interactions, have been related to Megaspeed, and it was all completely normal and not unusual,” Jensen Huang said.

Megaspeed said it has hired outside lawyers to investigate and is cooperating with the US government. At the same time, the Chinese Embassy called the report part of a campaign of “groundless smears and slanders.”

The White House, CIA, and NSA have not commented on this report.
