Federal prosecutors have accused a California technology business owner, Greg Lui, of routing roughly $300 million worth of high-end servers loaded with US-made AI chips to China, according to a report from The Economic Times.

The case centers on one of the most sensitive categories in the global semiconductor trade: AI accelerators designed and fabricated in the United States, whose export to China Washington has restricted on national security grounds. Servers built around these chips are the workhorse hardware for training and running large AI models, and sustained Chinese demand for them has produced a persistent gray market since the US government began tightening export controls in 2022.

The $300 million figure attached to the allegations indicates the scale authorities believe a single operator can reach. At typical street pricing for AI servers, that sum corresponds to shipments spanning thousands of dual- and eight-GPU systems — volumes large enough to matter to chip suppliers' channel visibility and to the enforcement priorities of the Commerce Department's Bureau of Industry and Security.

Lui is described as the owner of a California-based technology company. The accusation is that his operation moved the hardware to Chinese buyers in circumvention of US export controls. Details of the specific chips, the number of shipments, the alleged buyers in China, and the timeline of the alleged activity were not specified in the report.

The case lands at a moment of acute friction in the semiconductor supply chain. The United States has progressively restricted the export of advanced AI chips and the servers that contain them, first under the October 2022 rules, then through subsequent rounds of tightening. Nvidia, the dominant supplier of AI accelerators, has repeatedly flagged in its regulatory filings that diverted or smuggled product is difficult to police once chips enter the distribution channel, and US officials have pressed allies in Southeast Asia to tighten transshipment controls.

Enforcement actions like the one against Lui are the other half of that policy. Export rules only bind if prosecutors can demonstrate that intermediaries knowingly moved restricted hardware to prohibited destinations. A $300 million alleged scheme would rank among the larger individual cases publicized to date and signals that federal authorities are pursuing the intermediaries, not just the end buyers.

For the commercial picture, cases of this magnitude carry two implications. First, they confirm the price gap that continues to make diversion attractive: restricted AI chips command substantial premiums in China, where domestic alternatives do not yet match top-tier US accelerators on training performance. Second, each high-profile prosecution increases pressure on distributors, resellers and integrators in the US and transit hubs to tighten know-your-customer checks — a compliance cost that lands across the server supply chain.

Lui's case will proceed through the US legal system, where the accusations must be proven. The Economic Times report did not specify the exact charges filed, the court, or Lui's response to the allegations.

How prosecutors fare against a defendant of this alleged scale will be watched closely by chip suppliers and server integrators alike, as the outcome will shape how much enforcement risk the gray market in AI hardware actually carries.
