Super Micro says it cooperated with Singapore, US, and Taiwanese inquiries

The AI server maker says it has shared information with authorities in three jurisdictions probing the alleged diversion of Nvidia-equipped servers to China. The probes all circle the same question: whether AI servers built with restricted Nvidia chips ended up in China despite export controls.

The core allegation is diversion. Servers that were not supposed to reach China reportedly found a way there anyway, carrying Nvidia chips that fall under export restrictions. The concern is that the hardware was routed through intermediaries to obscure its final destination.

Taiwan Investigation

In Taiwan, the investigation has involved allegations of falsified export documents. Taiwanese authorities seized approximately 50 Supermicro servers in May 2026 as part of that work. The probe has also touched Supermicro staff directly, with four employees placed on administrative leave and two remaining detained as of early July 2026.

Supermicro maintains it is not a target of the Taiwanese inquiry. The company says it has helped investigators over a period of several months, including supplying information and giving access to employees and records.

US Case

In March 2026, prosecutors filed charges against Supermicro co-founder Yih-Shyan "Wally" Liaw and two others. The charges are tied to an alleged $2.5 billion smuggling scheme involving diverting Nvidia-equipped servers to China through front companies based in Southeast Asia.

As of November 12, 2026, Singapore's Ministry of Home Affairs reported that Supermicro had provided "limited assistance" to its probes, which came amid multiple requests from US authorities. This characterization complicates the company's cooperation narrative.

Strategic Importance

Advanced AI chips have become a strategic asset, with the US restricting which can be shipped to China. Supermicro's position in the AI supply chain makes it a natural focus for enforcement agencies when diversion is suspected. The multi-country nature of the probes reflects how these supply chains actually work, crossing several borders before reaching final destinations.

For now, Supermicro's message is consistent: it is cooperating, it is not a target in Taiwan, and the business keeps running. Key developments to watch include the US case against Liaw, the status of detained employees in Taiwan, and whether Singapore's description of the company's assistance shifts.
