Megaspeed International has drawn the world's attention after the resignation of Jensen Huang as chief executive of Nvidia on Friday, which followed reports of extramarital affairs with an alleged Chinese spy and two company employees. US intelligence agencies believe the alleged spy was Alice Huang (no relation), the former director of Megaspeed International, a firm registered in Singapore with affiliates across the US, Asia and Australia.

A company registered everywhere, seen nowhere

The firm at the centre of the affair has been one of Nvidia's biggest foreign customers, purchasing nearly $5bn in AI chips and advanced hardware over the past three years. Its physical presence, however, is thin.

• •Singapore: the Straits Times reported that Swiftdata, the little-known owner of Megaspeed, had a registered Singapore business address that an interior design firm said it had occupied for more than four years; last year the New York Times visited Megaspeed's Singapore headquarters in the central business district and found only two employees present
• •Malaysia: the New York Times found one office was a dilapidated storefront in the capital and another was in a shopping mall, where an employee, asked about the company's business, said: "It's not clear."

The Sydney office no one knew

Megaspeed Australia operates from the 10th floor of a city-centre office building in Sydney with no signage or mailbox identifying it. Nobody in the building had heard of Megaspeed Australia or its listed director, 29-year-old Kai Kang.

Corporate filings show a carefully drawn structure:

• •Megaspeed International filed papers in Delaware and with Asic showing the affiliates were created in 2024, listing the Shanghai-born Kang as sole company officer, either as director or president
• •The Australian filing lists the Singapore-based parent as Megaspeed Australia's stockholder
• •Asic documents show Kang was born in 1996 in Shanghai and has been Megaspeed Australia's director since registration; Megaspeed International owns all 10,000 shares of Megaspeed Australia's stock, for which it paid $1m
• •Kang is also registered as a director in Megaspeed's Malaysian, Indonesian and Thai units; he has not been accused of wrongdoing

Reuters visited the affiliates' registered home address: a news agency and lottery retailer in Seymour, Victoria, about an hour's drive north of Melbourne. A woman identifying herself as Kang's mother said she had run the Seymour business for about 16 years, that Kang was based in Shanghai and did not know anything about the Singaporean company. She added that he had completed his master's degree at Shanghai University and most recently visited his parents in August and September.

Investigations across multiple jurisdictions

Regulators and police in several countries have moved against the company. Singapore police said last October they were investigating Megaspeed over "suspected breaches of our domestic laws" after a US senator asked the commerce department to examine whether the firm diverted Nvidia chips.

• •Singapore's ministry of home affairs said this week it had held Alice Huang's passport from June 2025 until February over "potential false declarations" related to Megaspeed; she was released with a stern warning
• •On Thursday, Singaporean authorities said Alice Huang had been barred from re-entering the city state after a 2025 investigation into the company
• •Taiwanese authorities said earlier this week that she had also been barred from re-entering Taiwan
• •On Friday, Malaysia said it was investigating a subsidiary of Megaspeed International over the possible diversion of advanced AI chips to other countries

Spy claims and official silence

The Chinese government has rejected the claims against Alice Huang. A foreign ministry spokesperson, Guo Jiakun, said earlier this week the allegations were "unsubstantiated" and "nothing but smears against China".

In Australia, officials have been cautious. Michael Shoebridge, director of Strategic Analysis Australia and a former deputy of the Australian Signals Directorate and Defence Intelligence Organisation, said key details about Megaspeed's relationship with Chinese intelligence remained unclear. He suggested it would be "credible" to assess the company as a "front for Chinese intelligence" but that nothing was certain, and that the Australian operation might exist to make the parent look credible.

Acting prime minister Richard Marles told ABC radio: "We are living in a world where there is more espionage than there has been for a long time." Asio declined to comment when asked if it was examining Megaspeed Australia, and the office of the Australian home affairs minister, Tony Burke, also declined. The federal opposition said any potential foreign interference "must be taken seriously".
