Supermicro’s co-founder was just arrested for allegedly smuggling $2.5 billion in GPUs to China

Federal agents on Thursday arrested Yih-Shyan “Wally” Liaw, a prominent Silicon Valley executive deep in the AI ecosystem who co-founded Supermicro in 1993 and is a close confidante of CEO and chairman Charles Liang. The stock tumbled roughly 12% in after-hours trading following the news.

According to a stunning release from the Department of Justice, an indictment was unsealed in Manhattan federal court on Thursday charging Liaw, 71, and two others with allegedly working in secret to divert billions in Supermicro AI servers to China in violation of U.S. export control laws. The two alleged co-conspirators charged alongside Liaw include Supermicro’s Taiwan general manager Ruei-Tsang “Steven” Chang, who remains a fugitive, and a third-party fixer named Ting-Wei “Willy” Sun, who was also taken into custody on Thursday. 

The DOJ claims during 2024 and 2025, Liaw took a direct hand in the alleged conspiracy, working with Chang to allegedly find Chinese buyers who wanted the servers, which are packed with highly coveted GPU chips. The pipeline they allegedly constructed worked this way: Liaw and Chang would allegedly direct executives at an unnamed Southeast Asian company to place purchase orders with Supermicro as though they were destined for that company’s operations. The servers would then get assembled in the U.S., shipped to Supermicro’s facilities in Taiwan, and then delivered to the Southeast Asian company at a different location. From there, the Southeast Asian company, in tandem Liaw and Chang, would hand the servers off to a shipping and logistics company, which would allegedly get rid of the identifying packaging. They would allegedly put the servers in unmarked boxes before sending them to their true destination, which was China. 

To keep the clandestine scheme from raising red flags with Supermicro’s compliance team, the defendants and the Southeast Asian company executives would fake documents and send false communications meant to show that the Southeast Asian company was the legitimate end buyer. During the two-year period, that company purchased about $2.5 billion worth of Supermicro servers under the alleged arrangement. The operation eventually grew even more “brazen,” authorities claim. The DOJ alleges that during a three-week period from late April to mid-May 2025, about half a billion worth of servers assembled in the U.S. were shipped to China as part of the alleged conspiracy. 

To keep it under wraps, the defendants allegedly staged thousands of fake dummy servers—actual, physical replicas of Supermicro’s actual products, authorities claim—at the warehouse where the Southeast Asian company was supposed to be storing its purchases. In reality, the real servers were long gone and had allegedly been shipped to China already. 

The DOJ claims surveillance cameras filmed Sun and an unnamed co-conspirator unboxing the fake servers, using a hair dryer to remove and reapply serial-number stickers and labels onto the dummy server boxes, then carefully repackaging them to pass inspection. The same phony servers were later used........
