Supermicro Stock Plunges 28% After Co-founder Arrest
U.S. prosecutors have charged three men with operating a scheme to illegally export high-performance Nvidia chips and servers to China. Authorities say the defendants used shell companies in Southeast Asia and falsified documents to hide the true destination, moving at least $2.5 billion worth of technology since 2024. Yih-Shyan Liaw (71), co‑founder of Super Micro Computer, and Ting‑Wei Sun (44) were arrested in California; Ruei‑Tsang Chang (53), director of the company’s Taiwan office, is reportedly at large. U.S. prosecutors described the case as a systematic conspiracy to route U.S. AI technology to Chinese customers in violation of export restrictions. Super Micro Computer said the employees breached company policies and that it is cooperating with authorities.
Significant legal action affecting a major server vendor and the supply chain for AI compute hardware; potential implications for export-control compliance and hardware availability, but not directly about AdTech/MarTech operations.

U.S. Execs Charged for Smuggling Nvidia Chips to China
U.S. prosecutors in the Southern District of New York unsealed an indictment alleging that associates of a U.S. server maker illegally diverted Nvidia-powered servers to China, violating the Export Control Reform Act. The indictment names Yih-Shyan “Wally” Liaw, Ruei-Tsan “Steven” Chang and Ting-Wei “Willy” Sun and alleges a Southeast Asian middleman repackaged and used “dummy” servers and doctored paperwork to conceal shipments. Liaw is a Super Micro Computer co‑founder and board member; the company says Liaw served as senior vice president of business development, Chang as a Taiwan sales manager and Sun as a contractor. Super Micro shares fell about 33% after the indictment; prosecutors say the illicit channel produced roughly $2.5 billion in sales since 2024, including about $510 million in shipments between April and May 2025. Liaw and Sun were arrested; Chang is described as a fugitive. The indictment asserts the server exports lacked required U.S. Commerce Department licenses for sale to China.
U.S. Moves to Close Remote-Access Loophole for Nvidia Chips
The U.S. has banned exports of Nvidia’s most advanced AI chips to China, but officials and lawmakers are increasingly concerned that Chinese firms are circumventing those controls by using remote access to chips housed in Southeast Asian data centers. Reports name Moonshot AI and other Chinese firms using overseas facilities to tap Nvidia GB300 compute. A proposed bill, the Remote Access Security Act (RASA), passed the House and would expand export controls to cover remote cloud access; it has not passed the Senate. The Commerce Department’s Bureau of Industry and Security (BIS) could also issue rules to restrict remote access, but policymakers face technical and enforcement challenges, including defining covered compute and implementing robust know-your-customer measures.
Moonshot AI accessed Nvidia chips despite export ban
A White House official said Chinese AI company Moonshot AI accessed Nvidia’s advanced GB300 chips overseas despite U.S. export controls. Moonshot recently released the Kimi K3 model (reported at 2.8 trillion parameters), which the White House alleges benefited from access to GB300-equipped servers in Thailand and from distillation of Anthropic’s Fable. U.S. lawmakers and officials are examining export-control loopholes and proposed legislation (the Remote Access Security Act) to restrict remote/cloud access to advanced hardware; Treasury officials have warned sanctions and Entity List actions for IP-theft style distillation campaigns.
