Why Singapore Is Central to Nvidia Chips and China Controversy

Singapore, which handles billions of dollars in Nvidia sales each year, is facing renewed scrutiny from Washington over the movement of advanced artificial intelligence chips to China. The spotlight has intensified as a scandal involving the chipmaker’s chief executive once again draws attention to the city-state.

Singapore said Thursday that it had refused entry to Alice Huang, the businesswoman at the center of a controversy that helped bring Jensen Huang’s tenure as Nvidia CEO to an end.

On Friday, prosecutors charged a fifth individual in a Singapore fraud investigation involving computer servers that may have contained Nvidia chips before being shipped to Malaysia. Authorities said the wider case involved transactions worth roughly $390 million, based on figures released in March of last year.

Investigations into multiple companies and senior figures, including Megaspeed International, began in February 2025 and were still underway as of Thursday.

Singapore’s Ministry of Home Affairs said authorities were examining whether servers sent through Singapore to Malaysia, without being brought into the local market, were later diverted elsewhere in violation of the declarations filed in Singapore.

The city-state has come under increasing international pressure, especially from the United States, because of its role as a major billing center and possible transit point for Nvidia chips that U.S. officials say have reached China.

Since 2022, Washington has restricted Nvidia’s most advanced AI processors from being exported to China, citing concerns about Beijing’s rapidly expanding artificial intelligence capabilities.

Singapore accounted for 22% of Nvidia’s revenue in the fiscal quarter that ended in July 2025, compared with 8% in 2023. Singapore’s trade ministry, however, has estimated that chips physically delivered to the country represented less than 1% of Nvidia’s total revenue.

Analysts say weaknesses in the enforcement of U.S. export rules, combined with the complexity of Singapore’s corporate structure, can make it difficult to track the final destination of advanced Nvidia processors.

Nvidia chips may be sold legally to buyers in countries such as Singapore or Malaysia, then illegally resold or re-exported to China. Chinese companies can also access cutting-edge processors remotely through data centers located outside China, avoiding the need to purchase the hardware directly.

Chris McGuire, a senior fellow at the Council on Foreign Relations and a former U.S. national security official, said Southeast Asia has emerged as “a major hub for chip smuggling and export control circumvention,” with the region importing tens of billions of dollars in AI processors annually.

Singapore has increased its efforts to investigate suspected chip diversion since last year, launching probes that include allegations of fraud and money laundering.

Alvin Camba, lead scientist and research director at Austin-based AI risk assessment company Lyvi, said authorities had acknowledged possible “blind spots between separate monitoring of trade flows and banking flows.” Matching physical shipments with the financial activity connected to them can be “challenging,” he said.

Singapore’s robust corporate confidentiality rules, which provide significant protections for overseas investors, may also slow efforts to determine who ultimately receives imported goods, Camba said.

Such weaknesses can be used to “obfuscate financial flows and potentially circumvent global restrictions on technology transfers,” he added, arguing that regulators must continually adjust their oversight methods.

Singapore said U.S. authorities had provided only limited assistance during its yearlong investigation.

Police requested information about Super Micro Computer Inc., the U.S. server maker connected to the inquiry, but the company offered only limited cooperation, according to a statement released Thursday.

The city-state initially brought the matter to U.S. officials in July 2025 and renewed its requests several times beginning in September of that year. “Despite these repeated requests, Singapore has to date received limited information or assistance in respect of the company,” the government said.

In June 2025, Singaporean police questioned Alice Huang, a Hong Kong resident who at the time served as Megaspeed’s CEO, chairperson and a key controller of the company.

Authorities determined in February 2026 that there was not enough evidence to establish that Huang had committed offenses connected to the declarations under review. She was nevertheless barred from returning to Singapore after officials concluded that she had given inaccurate information that minimized her role at Megaspeed.

The ministry said Singapore does not enforce “unilateral export controls” imposed by other nations. However, companies operating in the country are expected to consider foreign export regulations when conducting international business.

Megaspeed, which was separated from a Chinese gaming company, became Nvidia’s biggest customer in Southeast Asia in under three years. The New York Times reported that it had purchased more than $4.8 billion worth of Nvidia chips since June 2024, although Megaspeed has denied wrongdoing.

U.S. intelligence officials have identified Alice Huang as a Chinese intelligence asset accused of passing information to Beijing. She worked as Megaspeed’s managing director for eight months in 2023 and has reportedly remained influential within the company.

Jensen Huang resigned as Nvidia CEO on Thursday after 33 years leading the company. The move followed revelations about two extramarital relationships and plunged the chipmaker, a central force in the global AI boom, into turmoil.

Nvidia named Chief Financial Officer Colette Kress interim CEO while its board begins the search for a permanent successor.
