Amidst allegations that a Chinese businesswoman, with whom he had a romantic relationship, was gathering intelligence for Beijing, Nvidia's CEO Jensen Huang is under investigation for potential involvement in foreign espionage. The 63-year-old Taiwanese-American co-founder of the second most valuable company globally, Nvidia, has admitted to infidelity but the firm maintains that no sensitive information or US national security has been compromised. However, the board of directors has announced an independent investigation into whether Huang was targeted by a foreign intelligence operation following media reports linking him to Alice Huang, a former executive at a Singapore-based data centre company. These allegations come as Washington seeks to prevent China from obtaining advanced American semiconductors, including Nvidia's most powerful artificial intelligence chips, in the race for AI supremacy between the US and China. The affair details are unclear, with questions about the information Alice Huang allegedly obtained, whether any sensitive material was passed to Beijing, and how much Jensen Huang knew about the alleged operation. The controversy has led to a 4% drop in Nvidia's stock price, with investors expressing concern over potential national security implications. Jensen Huang's daughter, also employed at Nvidia, has cancelled a planned visit to South Korea amidst the controversy. US authorities have been investigating Alice Huang's company, Megaspeed, since 2024 over suspicions of aiding China in obtaining advanced technology.
