Nvidia is facing two related but distinct, unsubstantiated investigations involving Singapore-based Megaspeed International, former executive Alice Huang and Chief Executive Jensen Huang. U.S. intelligence agencies reportedly consider Alice Huang a Chinese intelligence asset, while the Commerce Department investigated whether Megaspeed diverted Nvidia AI chips through Malaysia to China before transferring the case to the Justice Department. Nvidia lawyers contacted investigators before the Commerce probe was halted, but reporting does not establish that the contact caused the change in handling. Huang acknowledged an intimate relationship with a business executive, apologized to his wife and Nvidia, and said he would cooperate with the company’s independent investigation. China rejected the espionage allegations as a smear campaign. Nvidia denies wrongdoing, says earlier reviews found no diversion, has accounted for every deployed GPU and says Megaspeed has no Chinese shareholders. No charges or illegal diversion of U.S.-origin chips have been publicly established, while Singapore authorities are conducting their own investigations.
