Supermicro Co-Founder Arrested in $2.5 Billion AI Chip Smuggling Scheme to China

Federal prosecutors charged three men linked to Super Micro Computer in a sweeping scheme to smuggle $2.5 billion worth of US AI servers to China using fake documents, shell companies, and thousands of dummy servers to deceive inspectors.

Introduction

Federal prosecutors have charged three men linked to Super Micro Computer Inc. in what authorities describe as a sweeping scheme to smuggle $2.5 billion worth of US artificial intelligence technology to China. The defendants allegedly used fake documents, shell companies, and thousands of “dummy servers” — non-working physical replicas — to deceive inspectors and evade export controls.

The case highlights the intense global competition for advanced AI chips and the lengths to which some actors will go to circumvent US export restrictions.

The Defendants

Yih-Shyan “Wally” Liaw, 71 — A US citizen and co-founder of Supermicro. He served as senior vice president of business development and board member.

Ting-Wei Sun, 44 — A Taiwan national who worked as a contractor for Supermicro.

Ruei-Tsang Chang, 53 — A Taiwan national and Supermicro sales manager in Taiwan. He remains at large.

Liaw and Sun were arrested Thursday. Chang is still being sought by authorities.

How the Scheme Worked

According to the indictment unsealed in the Southern District of New York, the scheme operated through a sophisticated network:

  1. Fake end users: The defendants worked with brokers and customers in China to place purchase orders through a Southeast Asia-based company, making it appear that company was the end user.

  2. Transshipment route: Servers were assembled in the US and shipped to the Southeast Asian company, which then repackaged them in unmarked boxes to conceal their contents before shipping to China.

  3. False documentation: The defendants and company executives prepared fake documents and communications showing the Southeast Asian company was the legitimate end user.

  4. Dummy servers: Perhaps most striking, the defendants staged thousands of non-working replica servers to deceive the US manufacturer’s compliance team during inspections.

The Hair Dryer Detail

Surveillance video captured the defendants in a warehouse using a hair dryer to remove and reapply labels and serial number stickers to server boxes and dummy servers ahead of a US Department of Commerce inspection.

The dummy servers were then repackaged in the US manufacturer’s boxes to pass visual inspection, while the real AI servers were diverted to China.

Scale of the Operation

The numbers are staggering:

  • $2.5 billion in AI servers allegedly diverted to China
  • $510 million in just a few weeks in 2025 alone
  • Thousands of dummy servers manufactured to deceive inspectors
  • The servers contained restricted GPUs, including Nvidia AI chips subject to export controls

Supermicro’s Response

Supermicro said it was informed by the US Attorney’s Office that three individuals associated with the company had been indicted. The company emphasized:

  • It is not named as a defendant in the indictment
  • Liaw was placed on administrative leave
  • The contractor relationship with Sun was terminated
  • The company says the alleged conduct violates its policies and compliance efforts

“The conduct alleged in the indictment violates the company’s policies and efforts to comply with export control laws,” Supermicro said in a statement.

The Charges

The defendants face serious federal charges:

  • Conspiracy to violate the Export Control Reform Act — Maximum 20 years in prison
  • Conspiracy to smuggle goods — Maximum 5 years
  • Conspiracy to defraud the United States — Maximum 5 years

Why This Matters

National Security Implications

Assistant Attorney General for National Security John A. Eisenberg called the chips “the product of American ingenuity” and vowed to continue enforcing export-control laws “to protect that advantage.”

The case underscores US concerns about China’s efforts to obtain advanced AI technology that could be used for military applications, surveillance, or to compete with American AI companies.

The AI Chip Wars

Nvidia’s AI chips have become some of the most restricted technology exports in the world. The US government has imposed increasingly tight controls on sales to China, concerned about:

  • Military AI applications
  • Surveillance capabilities
  • Economic competition in AI development
  • National security implications of advanced computing

Corporate Compliance Challenges

The case raises questions about how multinational technology companies can prevent employees from circumventing export controls, especially when the financial incentives are enormous.

Market Impact

Supermicro stock (SMCI) fell sharply following the news, dropping more than 20% as investors reacted to the indictment of a co-founder and senior executive.

The company has faced scrutiny before, including accounting-related investigations, but this case represents a new level of legal exposure.

What Comes Next

  • Prosecution: The case will proceed in federal court in Manhattan
  • Chang’s arrest: Authorities are still seeking the third defendant
  • Company fallout: Supermicro will likely face increased regulatory scrutiny
  • Industry impact: Other tech companies may review their export compliance procedures
