The unusual global footprint of Megaspeed International, the Singapore-based company at the center of the Nvidia Chinese spy scandal, is fueling questions about whether it's a front for the Chinese government.

One of Megaspeed's leaders is Alice Huang, the woman with whom Nvidia CEO Jensen Huang was having an affair, and who is suspected by U.S. intelligence of being an asset of China's Ministry of State Security. In the past three years, Megaspeed, formerly a gaming company, has been one of Nvidia's biggest foreign customers, purchasing nearly $5 billion in AI chips and advanced hardware, The New York Times first reported.

And yet Megaspeed's corporate headquarters sat practically empty, according to The Straits Times, an English-language newspaper in Singapore. Questions have also been raised about its outposts in Australia and Malaysia.

Published reports in recent days revealed that the company listed a newspaper vendor as the director of its Australian subsidiary, and one of its Malaysia offices consisted of a dilapidated storefront outside Kuala Lumpur. Yet another Malaysia office was tucked into a shopping mall.
