Nvidia Probes Alleged Intelligence Operation Involving CEO

Nvidia is investigating whether chief executive Jensen Huang was targeted by a foreign intelligence operation, as U.S. authorities examine allegations involving Singapore-based Megaspeed and its former director Alice Huang. The allegations that Alice Huang was a Chinese intelligence asset remain unproven, and China has rejected them as unsubstantiated.

Jensen Huang told Nvidia staff in a Nov. 8 memo that he had been unfaithful to his wife, but did not name the woman. Nvidia’s board said it had no reason to believe national security or company secrets had been compromised. It said Huang would remain in charge while cooperating with the board’s investigation.

U.S. intelligence officials concluded that Alice Huang was a Chinese intelligence asset, according to reporting cited in the accounts. The evidence behind that assessment has not been made public in the reporting. China’s Foreign Ministry rejected the allegation, calling it unsubstantiated and a smear against China. Alice Huang has not spoken publicly about the accusations, and she could not be reached for comment.
