Singaporean authorities seized the passport of Alice Huang, then Megaspeed’s chief executive, in June 2025 and detained her for eight months, preventing her departure while trying to get the U.S. government to support their investigation into advanced cases. Nvidia chips could be shipped to China.
A source familiar with the matter told CBS News on Friday that the Singapore government had received no significant aid from Washington during its stay in the Asian city-state. This source said Washington officials have “failed to respond” to Singapore’s requests for help, and no substantial assistance has been provided to date.
The Singapore government confirmed in a statement this week that it had contacted the US Department of Justice and the FBI for assistance in its investigation.

Since February 2025, Singaporean authorities have been investigating whether Alice Huang and Megaspeed worked with California-based Supermicro to ship the Silicon Valley company’s computer servers — powered by advanced Nvidia chips — to China, the source told CBS News.
Alice Huang traveled to Singapore in June 2025 for a voluntary interview with investigators from the US Bureau of Industry and Security based in Singapore, according to the source.
The agency sits within the U.S. Department of Commerce and regulates the export of sensitive products for national security and economic reasons. U.S. authorities requested the interview, according to a statement released Thursday by Singapore’s Ministry of Home Affairs, as part of a post-shipment verification check, a process used to determine whether imported products have reached their declared recipient.
Singaporean police also questioned Huang the same day as U.S. officials and made the decision to confiscate his passport.
The source said it was unclear where Huang, a Chinese national, arrived in Singapore from in June 2025.
However, as of February 2026, Singapore police had not charged Huang with any crime and had no choice but to return his passport, the source told CBS News. She was banned from returning to Singapore because authorities believed she had given “inaccurate information” to downplay her role at Megaspeed, the Home Office statement said.
The statement was released four days after Jensen Huang admitted to having an affair with a woman who sources confirmed to CBS News was Alice Huang.
The Singapore investigation focused on whether Megaspeed’s then-CEO broke national law by lying about details of computer server purchases from Supermicro, a San Jose-based technology company. The company’s servers use Nvidia’s advanced chips to run artificial intelligence software, data centers and cloud computing.
“The alleged domestic offenses related to potential misrepresentations regarding the purchase of servers and other related offenses,” Singapore’s Ministry of Home Affairs said in its statement this week.
Singaporean investigators attempted to determine the true final destination of the Supermicro servers ordered by Megaspeed.
A second source close to the investigation told CBS News they could have been sent to Malaysia, but Singaporean investigators suspect “some or all” of them may then have been shipped to China. Megaspeed has denied any wrongdoing.
Singapore’s Home Office attempted to contact Supermicro, but the US company provided only “limited cooperation”, according to the Home Office statement.
The New York Times reported on Wednesday that Malaysia kept Nvidia’s chips and installed them in its own data centers, but then leased use of those centers to China, rather than physically shipping chips to China.
Malaysian Prime Minister Anwar Ibrahim said Friday there was “no indication” that chips linked to the Nvidia-Megaspeed issue had been re-exported out of the country.
Beijing has dismissed allegations that Alice Huang is a Chinese spy, calling them “baseless speculation” and “nothing more than an attempt to defame China.” Asked Thursday about a Bloomberg report that she had returned to China, Foreign Ministry spokesman Mao Ning told reporters: “I have no information about what you mentioned.”
Since 2022, the United States has restricted the export of Nvidia’s most powerful chips to China over national security concerns as the world’s two largest economies. race for dominance in the AI sector.
Singapore police first raised the issue with US authorities in July 2025 in an attempt to gain cooperation from Supermicro in revealing where its servers ultimately ended up, reiterating their requests “repeatedly with the US Department of Justice and the Federal Bureau of Investigation”, according to the statement released by the Interior Ministry on Thursday.
The second source confirmed to CBS News that Washington had not responded meaningfully to requests for assistance in the investigation and said it “would be helpful to know” what Supermicro said about its exports to fulfill Megaspeed orders, whether those products were registered as going to Malaysia, and whether some or all of those products were actually “destined for another location,” such as China.
Singapore’s Home Ministry said in its statement that six other people linked to Megaspeed, in addition to Alice Huang, were wanted for questioning, but none had been in the country since the government launched its investigation in February 2025.
“One is a Singaporean citizen and the others are foreigners,” said the first person familiar with the matter.
Singapore has charged five other people in a broader fraud conspiracy case linked to the alleged transfer of Nvidia chips, including a Chinese man charged on Friday. The case was launched at the same time as the investigation into Alice Huang and Megaspeed, the first source told CBS News, but is separate.
“Singapore is committed to maintaining our reputation as a trusted and trusted business center. We will not allow companies or individuals to misuse Singapore’s business environment to engage in fraud or dishonest practices,” the Home Ministry said in its statement, adding that it would “conduct its own investigations independently, in accordance with our laws and based on available evidence. We will cooperate with foreign authorities where appropriate and take action firm coercive measures whenever the evidence so warrants.
