Yih-Shyan “Wally” Liaw, a Silicon Valley tech veteran and cofounder of Supermicro, was arrested Thursday on charges of illegally funneling billions of dollars worth of AI servers equipped with Nvidia GPUs to China. The arrest sent Supermicro’s stock plunging 12% after hours.
Allegations of a Clandestine Export Scheme
Federal prosecutors in Manhattan unsealed an indictment accusing Liaw, 71, along with two accomplices, of orchestrating a complex operation to bypass U.S. Export controls on advanced AI server technology. The servers in question are powered by Nvidia’s top-tier graphics processing units (GPUs), highly sought after for artificial intelligence applications.
The indictment alleges that between 2024 and 2025, Liaw collaborated closely with Supermicro’s Taiwan general manager, Ruei-Tsang “Steven” Chang, who remains at large, and a third-party fixer, Ting-Wei “Willy” Sun, who was also taken into custody.
According to prosecutors, the trio set up an elaborate front using a Southeast Asian company as a cover. The company would place orders with Supermicro in the U.S., supposedly for its own operations. This servers were then assembled stateside, shipped to Supermicro’s Taiwan facilities, and delivered to the Southeast Asian company’s different location. From there, the servers were repackaged in unmarked boxes and shipped directly to China, evading detection by U.S. Authorities.
Deceptive Tactics and Fake Documentation
To keep Supermicro’s internal compliance teams off the trail, Liaw and his alleged partners reportedly falsified documents and communications. These were designed to convince regulators and company staff that the Southeast Asian firm was the legitimate end user of the servers.
The operation was massive, with the Southeast Asian company purchasing approximately $2.5 billion worth of Supermicro servers during the two-year period. The DOJ specifically highlighted a three-week interval from late April to mid-May 2025 when nearly $500 million worth of servers were shipped to China under this scheme.
One of the more brazen elements involved the storage of thousands of fake dummy servers at the Southeast Asian company’s warehouse. These physical replicas served as decoys to convince inspectors and auditors that the real servers were still in place, while the genuine products had already been dispatched to China.
Surveillance and Evidence
Government officials gathered surveillance footage capturing Sun and another co-conspirator opening the dummy servers. The footage showed them using a hair dryer to peel off and reapply serial number stickers, a method allegedly used to disguise the servers’ true identities and origins.
The indictment paints a picture of a well-planned and coordinated effort to skirt U.S. Export restrictions designed to limit China’s access to cutting-edge AI computing technology.
Market and Industry Impact
Supermicro, a key player in AI infrastructure, saw its share price drop sharply following the announcement. The company, co-founded by Liaw in 1993, has long been a critical link in the supply chain for AI servers that power everything from cloud computing to autonomous systems.
The case makes people wonder about how export controls are enforced and the vulnerabilities in global supply chains that can be exploited to move restricted technology across borders.
Meanwhile, Nvidia’s GPUs, which are at the core of Supermicro’s AI servers, remain among the most coveted hardware components worldwide. Their advanced processing power is vital for AI research and development, making them a target for geopolitical tensions surrounding technology access.
Liaw’s arrest marks a rare but high-profile example of alleged export control violations involving AI technology. With one co-conspirator still at large and investigations ongoing, the case could have far-reaching implications for tech companies and regulators trying to keep pace with rapidly evolving AI hardware demands.
