Nvidia's board of directors has launched an internal investigation into reports that CEO Jensen Huang was the target of a Chinese intelligence operation, the company confirmed Sunday. The probe follows a series of reports alleging that Huang maintained a close relationship with Alice Huang, a Chinese national and businesswoman who ran a Singapore-based company that purchased nearly $5 billion in Nvidia chip technology. The two are not related. "While the Board has no reason to believe that either national security or NVIDIA secrets were compromised, the Board's inquiry will examine all available information," the board said in a statement. The reporting suggests Alice Huang may have helped China circumvent U.S. export limits on advanced AI chips. She was reportedly seen with Jensen Huang on multiple occasions after industry events in Taiwan, including at a bar with other suppliers and at dinner with executives. Jensen Huang addressed the matter in an email to employees on Sunday, acknowledging the relationship and apologizing for being unfaithful to his wife. "I support the investigation and will cooperate fully," Huang wrote. "I love our country and our company. I am committed to protecting NVIDIA and supporting America's national security. I am proud and grateful to be an American." The controversy has drawn attention from Capitol Hill. Last week, three Republican members of Congress sent a letter to Huang requesting that he brief lawmakers about the relationship and about the company's "security protocols against foreign adversary espionage." Nvidia dominates the global market for AI chips and has seen explosive growth in recent years. The company began as a manufacturer of graphics chips, which later proved crucial for training artificial intelligence systems. Huang and President Trump have repeatedly appeared together in public in recent years. According to Huang, Nvidia is helping to fund the construction of a new ballroom at the White House. The Chinese Embassy in Washington did not respond to a request for comment.
