Singapore barred Alice Huang from re-entering the country after she gave police inaccurate information about her role at Megaspeed. The Ministry of Home Affairs disclosed the ban on Thursday. Singapore also said it had asked US authorities for information for more than a year and received only limited assistance.
Alice Huang, a former Megaspeed executive, sits at the centre of the scandal that ended with Jensen Huang’s resignation as Nvidia CEO . The two share a surname but no family ties.
Singapore’s police and customs began investigating several companies, Megaspeed among them, in February 2025, the ministry said in a statement . The case covers possible false declarations about servers that companies exported through Singapore to Malaysia. Police want to know whether those servers then went on to another destination, contrary to the declarations. No country asked Singapore to open the case, the ministry said.
Police investigated Alice Huang as Megaspeed’s then chief executive, chairperson and one of its key controllers, not for espionage, the ministry said.
On 24 June 2025, the US Bureau of Industry and Security ran a check at Megaspeed with her present. That was the first time Singapore learned of the US interest in Megaspeed and Huang, the ministry said. Police interviewed her the same day and held her passport. In February 2026, after consulting the Attorney-General’s Chambers, they concluded there was not enough evidence that she had committed an offence.
Police did find that she had knowingly given them inaccurate information about her role, the ministry said. She received a stern warning and a ban on returning, and left Singapore on 26 February, the day police returned her passport. The police investigations into Megaspeed and six other people continue. Separately, Singapore has charged four people and four companies since February 2025. The charges include fraud over server purchases, the ministry said.
Singapore wanted information on Supermicro, the US server maker, which “provided limited cooperation”, the ministry said. Its police and the Attorney-General’s Chambers raised this with US authorities at a meeting on 7 July 2025. From September 2025, police repeated the request several times to the US Department of Justice and the FBI.
“Despite these repeated requests, Singapore has to date received limited information or assistance in respect of the company,” the ministry said.
Supermicro has said it is cooperating. On Thursday, a Supermicro spokesperson told Semafor that the company had worked with the authorities in all three countries.
Supermicro “has fully cooperated with US and Taiwanese officials, while also voluntarily providing information and engaging with all requests from Singapore authorities to date,” the spokesperson said.
Justice Department probes look at Megaspeed and Supermicro, and at Alice Huang’s role, Semafor has reported. In Washington, Commerce halted its own Megaspeed probe after Nvidia’s lawyer stepped in, The New York Times reported . Nvidia has said it cut off Megaspeed in 2025. Malaysia runs its own chip probe into Megaspeed’s local unit.
US officials disagree over whether she spied for China, CNN reported on Thursday. The intelligence collected on her so far does not prove she was acting as a spy for Beijing, multiple sources told CNN. The FBI’s counterintelligence investigation into her continues, CNN said. Beijing has denied she is a spy, Reuters reported .
“No conclusions reached by the Department of Justice, or by me, or by [FBI] Director Patel around who she is or is not,” Attorney General Todd Blanche said on Thursday.
Representative Jim Himes, the top Democrat on the House Intelligence Committee, told Politico on Wednesday that he left a classified briefing unsure whether she knowingly gathered information for the Chinese government.
Taiwan has also revoked Alice Huang’s entry permit, Interior Minister Liu Shyh-fang told lawmakers on Wednesday, AFP reported . Taiwan’s immigration agency confirmed she had entered the island on a Hong Kong passport. She is now overseas, Liu said.
“If we had known she was a spy, we certainly would not have let her enter Taiwan,” Liu said.
Taiwan will review its screening procedures, she added.
