The co-founder of one of the world’s leading server manufacturers has been arrested in the United States on charges of orchestrating one of the largest illegal technology exports in American history — a scheme that allegedly funnelled $2.5 billion worth of advanced Nvidia AI chips into China in violation of strict US export controls.
Wally Liaw, a US citizen who co-founded Super Micro Computer, known as Supermicro, was arrested on 19 March following an indictment from the US Attorney’s office for the Southern District of New York. Two other men — Willy Sun, a Taiwanese national, and Steven Chang, also a Taiwanese citizen — were named as co-conspirators. Sun was arrested alongside Liaw. Chang remains at large and is considered a fugitive.
The charges centre on a single count each of conspiring to violate the Export Controls Reform Act. If convicted, each man faces a maximum prison sentence of 20 years.
The indictment describes an operation of considerable ingenuity and considerable audacity. Prosecutors allege that the three men arranged for Supermicro servers containing banned Nvidia GPU chips — the processing units that power modern artificial intelligence systems and which the United States has restricted from export to China without a government licence — to be sold to a company based in Southeast Asia. That company then repackaged the hardware, stripping the servers of identifying marks and forwarding them onwards to final destinations inside China. Of the $2.5 billion in servers allegedly routed through the scheme, prosecutors say approximately $510 million worth contained the restricted chips.
The mechanics of the deception were documented in surveillance footage cited in the indictment. Individuals were filmed using a hair dryer to loosen adhesive serial number labels from genuine, chip-loaded servers, transferring those labels onto dummy replica units — empty shells designed to pass inspection. The real servers, scrubbed of traceable identification, were then boxed without markings and dispatched through the intermediary network. When auditors arrived to verify inventory, what they saw were props.
Supermicro, which was not named as a defendant in the indictment, confirmed the roles of all three individuals. The company said the two employees have been placed on administrative leave and that its relationship with Sun’s contracting operation had been terminated with immediate effect. Supermicro’s shares fell 33% on the day the charges were announced — a single-session collapse that wiped substantial value from one of Silicon Valley’s established hardware names.
The case arrives at a pivotal moment in the technology contest between the United States and China. Washington has spent the past several years constructing an increasingly elaborate architecture of export restrictions designed to prevent China from accessing the advanced semiconductor technology required to train and run frontier AI systems. Nvidia’s H100 and related high-performance GPU series have been central to that effort — coveted by Chinese technology firms and research institutions, and formally restricted under rules that the Biden and Trump administrations both tightened. The restrictions reflect a bipartisan consensus that allowing China unrestricted access to the hardware underpinning AI development would pose a strategic risk.
The Supermicro prosecution is, in that context, more than a corporate fraud case. It is a test of whether those export controls have meaningful teeth — and whether the government can identify and prosecute circumvention schemes before they become entrenched supply chains. The sheer scale of what prosecutors allege — $2.5 billion, executed over what appears to have been a sustained period, using multiple jurisdictions and physical deception — suggests that the black market for restricted AI chips is not a fringe phenomenon.
For the global technology industry, the case raises uncomfortable questions about visibility into supply chains and the ease with which sophisticated actors can exploit the gap between the point of manufacture and the point of final use. The hair dryer detail may seem almost comical alongside the financial figures involved, but it illustrates a basic problem: export controls depend on the integrity of the humans implementing them, and that integrity is not guaranteed.
The case also adds to pressure on Taiwan’s role in the global chip trade. Both Chang and Sun are Taiwanese nationals, and the alleged pass-through entity was based in Southeast Asia — a routing pattern consistent with strategies used to obscure the final destination of restricted technology from origin-point controls.
Final Word
The arrest of Supermicro’s co-founder on charges of running a multi-billion dollar chip smuggling network is the most significant technology export enforcement action the United States has brought in years. It will not be the last. As the strategic value of advanced AI chips increases alongside the severity of the restrictions placed on them, the incentive to circumvent those controls grows proportionally. The prosecution sends a clear signal — but the signal will only hold if the infrastructure for enforcement can keep pace with the ingenuity of those determined to evade it.
