Nvidia chief executive Jensen Huang stepped down on Friday following revelations of extramarital affairs involving an alleged Chinese intelligence operative connected to Megaspeed International, a Singapore-registered firm. US intelligence agencies believe Huang may have been targeted by Alice Huang, identified as the former director of Megaspeed, and suspect he acted as a Chinese asset in passing proprietary information to Beijing, according to reporting by the New York Times.
Megaspeed has emerged as one of Nvidia’s largest foreign customers over the past three years, purchasing approximately $5 billion in artificial intelligence chips and related hardware. However, investigations across multiple countries have revealed the company maintains an unusually opaque operational structure. Singaporean authorities barred Alice Huang from re-entering the city state following a 2025 investigation into suspected breaches of domestic law. Singapore police had launched their inquiry last October after a US senator requested the commerce department examine whether Megaspeed diverted Nvidia chips. Taiwan and Malaysia have also restricted Huang’s entry and initiated their own investigations into the company’s activities.
Journalists attempting to locate Megaspeed’s offices have encountered puzzling findings. The company maintains registered addresses across Australia, Malaysia, Indonesia, Thailand and the United States, yet physical inspections reveal minimal staffing and unclear operations. The Australian office occupies a floor in a Sydney building with no signage or visible business presence. The listed Australian director, 29-year-old Kai Kang, is reportedly based in Shanghai according to his mother, who operates a lottery retailer and news agency in rural Victoria where corporate filings provided as his address. In Singapore, the New York Times previously found only two employees at the company’s supposed headquarters. Malaysian locations included a dilapidated storefront and a shopping mall office.
Australian security analysts have suggested Megaspeed could potentially function as a front for Chinese intelligence operations, though officials remain cautious about conclusions. The Chinese government has categorically denied allegations that Alice Huang worked as a spy, with a foreign ministry spokesperson characterizing the claims as unsubstantiated. Australian authorities have not publicly confirmed whether they are examining the local Megaspeed subsidiary.
