BEIJING — China dismissed allegations of an espionage plot targeting Nvidia Chief Executive Jensen Huang on Monday, labeling claims that a Beijing-linked operative ensnared the semiconductor pioneer as an unsubstantiated smear campaign.
The denial did little to calm Wall Street. Nvidia shares slumped roughly 5% in pre-market trading as investors weighed the fallout for the world's preeminent artificial intelligence chipmaker.
The controversy erupted after Huang disclosed to the Nvidia board of directors that he had engaged in an intimate relationship with a business executive whom U.S. intelligence identified as an operative gathering sensitive data for Beijing. That executive, Chinese national Alice Huang, ran a company facing allegations of illicitly smuggling restricted graphics processors into mainland China. While Huang acknowledged the extramarital affair to the board, he did not publicly name the executive.
Nvidia opened an internal corporate investigation on Sunday to trace the scope of any potential breach. The inquiry centers on corporate governance and national security: whether sensitive technological architecture was leaked, and whether Huang drove chip sales to Chinese buyers in defiance of Washington's trade barricades.
The stakes are staggering.
"The key questions are whether he was aware of any espionage activities and whether any confidential or strategically sensitive information was compromised," said George Chen, partner and chair of digital practice at Washington consultancy The Asia Group. "Those questions require evidence rather than speculation."
Huang spent recent years maneuvering through high-stakes geopolitical crosscurrents in Washington, personally lobbying U.S. President Donald Trump to permit commercial shipments of Nvidia's H200 processors to China. Prior to that push, Huang lobbied the White House to sell the less-advanced H20 chip, an architecture specifically throttled to comply with American export restrictions. Yet Beijing resisted wide-scale domestic adoption. An August regulatory filing revealed that Nvidia sold only limited quantities of the silicon, constrained by Chinese government curbs on local enterprise purchases.
Chinese Foreign Ministry spokesperson Guo Jiakun pushed back aggressively against the espionage claims during a regular press briefing in Beijing on Monday.
"The so-called Chinese spy allegation is unsubstantiated," Guo said. "It is nothing but smears against China."
Nvidia's internal review continues this week as compliance auditors examine executive communications and technical transfer records.
