Singapore has said the United States gave it only limited help in its investigation into Megaspeed International, the Singapore data-centre company at the centre of the Nvidia chip scandal, and has barred the firm's former chief executive, Alice Huang, from returning to the country. Singapore's Ministry of Home Affairs gave the account on Thursday, November 12, 2026.

The Singapore Megaspeed probe began in February 2025, when police and customs opened their own investigation into several companies and officials over suspected false declarations in server exports. More than a year later, Singapore says it repeatedly asked Washington for help in getting the American server maker Supermicro to cooperate — and got little back.

Key Points

• Singapore's Ministry of Home Affairs said on Thursday, November 12, 2026, that the United States gave limited help in its Megaspeed investigation.
• Police and customs opened the probe in February 2025 over suspected false declarations in server exports.
• Singapore raised the case with US officials on July 7, 2025, and again with the Justice Department and the FBI from September 2025, seeking Supermicro's cooperation.
• Police found insufficient evidence in February 2026 that Huang committed offences; her passport was returned on February 26 and she left the same day.
• Huang was given a stern warning and barred from re-entering Singapore after police found she gave inaccurate information to play down her role in Megaspeed.

What Happened

The Ministry of Home Affairs, known as MHA, set out the timeline in a statement on Thursday. Police and customs launched the investigation independently in February 2025 over suspected false declarations in server purchases and exports. The ministry said Singapore repeatedly sought help from the United States, raising the matter with US officials at a meeting on July 7, 2025, and again with the Justice Department and the FBI from September 2025.

The help Singapore wanted was specific: it wanted Washington to get Supermicro, the American server maker that supplied Megaspeed and works closely with Nvidia, to cooperate. According to the ministry, Singapore received only limited information or assistance in return.

The ministry also disclosed the outcome of the Singapore end of the case. Police concluded in February 2026 that there was insufficient evidence Huang had committed offences connected to the suspected false declarations. Her passport was returned on February 26, 2026, and she left Singapore the same day. But police assessed that she had given inaccurate information to downplay her role in Megaspeed, issued her a stern warning, and barred her from re-entering the country.

The ministry added two clarifications that matter. First, Huang was not investigated for espionage in Singapore. Second, the investigations into Megaspeed and six other individuals remain ongoing, so the company and its associates are still under scrutiny even though the case against Huang herself has been closed.

Background and Context

Megaspeed International is a Singapore-based cloud and data-centre firm that buys advanced Nvidia chips and builds the servers that power artificial intelligence systems. It is under investigation by the US Justice Department over allegations that it helped divert about $7.5 billion worth of Nvidia's most powerful AI chips to China, despite US export controls.

The company was drawn into a political storm this month after reports that Jensen Huang, Nvidia's chief executive, had an affair with Alice Huang, also known as Huang Le, a former Megaspeed executive. US officials suspect Alice Huang of being a Chinese intelligence operative recruited to gather information on Jensen Huang and to seek AI-chip secrets. Jensen Huang resigned on Thursday, November 12, ending a 33-year run at the company he co-founded; CFO Colette Kress is interim chief executive.

Singapore Megaspeed Probe: Why Washington's Help Mattered

The heart of Singapore's complaint is practical, not diplomatic. Supermicro is an American company, and its cooperation was something only Washington could compel. Singapore's investigators needed to know what servers were sold, to whom, and under what declarations, and Supermicro's records were central to answering those questions. Without that help, Singapore says, its probe into the suspected false declarations could only go so far.

Singapore first asked in July 2025 and again from September 2025, while US agencies were building their own case — and the two governments framed the matter differently, Singapore as a paperwork case and Washington as a suspected chip-smuggling channel.

Reactions: A Stern Warning, a Denial and a Wider Fallout

The stern warning and the re-entry ban are the sharpest measures Singapore has taken against Alice Huang. A stern warning is a formal police step short of prosecution, used when the evidence does not support a charge. The ban means she cannot return to Singapore, where she had been detained in the summer of 2025.

Megaspeed has denied wrongdoing. Its chief executive and chairman, James Tan Yong Pong, said this week that "compliance is a fundamental priority for the company, and Megaspeed is committed to working constructively and transparently with the US government." China has rejected the espionage allegations, calling them "groundless speculation" and a pretext for a technology blockade.

Why It Matters

Singapore's statement matters because it is the first official account from a government that investigated Megaspeed on its own ground, and its account is uncomfortable for Washington. If the United States gave only limited help to an ally investigating the same company it is now pursuing, lawmakers will want to know why.

The controls are Washington's main tool for keeping advanced AI chips from China's military, and they depend on cooperation across the supply chain — so a case where a key supplier's home government could not get the help it needed is a warning the system has gaps.

What Happens Next

Singapore's investigations into Megaspeed and six others continue. In the United States, the Justice Department's probe continues, and Nvidia's board is searching for a permanent chief executive while its own inquiry, led by former federal prosecutor Joon Kim, runs on. Congress is also moving: Warren and Coons expect confirmation by November 17 that records have been preserved, and Senator Michael Bennet wants written answers on Megaspeed by November 24.
