The United States has escalated its campaign to keep advanced artificial intelligence hardware out of China, arresting the chief executive of a California computer company accused of running a three-year smuggling operation worth more than $300 million.

On October 1, the Department of Justice announced the arrest of Greg Lui, CEO of Earthmade Computer Inc., on a three-count federal indictment: conspiracy to violate the Export Control Reform Act and the Export Administration Regulations, outbound smuggling, and conspiracy to commit money laundering. If convicted on all counts, he faces a maximum of 50 years in prison.

“This defendant allegedly used false paperwork and shipments through third countries to smuggle more than $300 million in export-controlled computer servers to China,” said Bill Essayli, First Assistant U.S. Attorney for the Central District of California, in the DOJ indictment report.

The case matters beyond the courtroom. It is the latest and largest in a string of enforcement actions targeting the diversion of Nvidia’s AI accelerators — the chips that have become the compute backbone of the global AI buildout — and it lands at a moment when U.S. chip policy toward China is under fresh political scrutiny.

What the DOJ alleges

According to the indictment and court documents, the scheme began in October 2023 and continued until at least August 2026. Lui allegedly used false paperwork to conceal shipments of high-end servers containing export-controlled Nvidia graphics processing units, misrepresenting their final destination as Malaysia or Singapore — jurisdictions where the restrictions do not apply — before rerouting them to buyers in China, including a Chinese firm in Hangzhou.

Prosecutors say Lui received more than $176 million in payments from two Malaysian transshipment companies, and in return introduced them to U.S.-based suppliers of Nvidia hardware, brokering sales of nearly $300 million worth of equipment. Court documents cited by prosecutors describe one specific order: 27 servers containing Nvidia H100 GPUs, worth about $7.6 million, shipped from Los Angeles to Kuala Lumpur before reaching a Chinese buyer. In one instance, the indictment alleges, a shipment’s recipient was fraudulently listed as “Jackie Lui” — a name tied to a California-registered front company.

“The FBI’s investigation revealed that Lui allegedly sold the Chinese government hundreds of millions of dollars’ worth of American super-intelligence technology, in clear violation of U.S. export control laws,” said Roman Rozhavsky, assistant director of the FBI’s Counterintelligence and Espionage Division.

The investigation was jointly conducted by the FBI, the Commerce Department’s Bureau of Industry and Security Office of Export Enforcement, and the Defense Criminal Investigative Service. Lui was arraigned and made his initial appearance on October 1.

A wider crackdown

The case is not an isolated enforcement action. Earlier in 2026, prosecutors brought a similar case involving individuals linked to server maker Super Micro Computer, accused of falsely routing Nvidia-loaded servers to China, and U.S. lawmakers — including Senators Jim Banks and Elizabeth Warren — have pressed for a formal review of Nvidia’s export compliance practices, questioning whether the company’s oversight of its supply chain is adequate. See the detailed case reporting for how the alleged scheme operated.

The political pressure reflects a structural shift. Semiconductor technology originally designed for computer gaming has become a driver of compute for artificial intelligence, turning GPUs into strategic assets regulated under U.S. export control law. Washington’s restrictions, in place in various forms since 2022, aim to slow China’s military and technological advancement by limiting its access to high-performance chips such as Nvidia’s H100 and H200 accelerators.

That pressure is reshaping the market. Bernstein analysts cited in recent reporting project that Nvidia’s share of China’s AI chip market could fall from roughly 40% in 2025 to about 8% by the end of 2026, with domestic suppliers led by Huawei filling the gap — a projection that illustrates how enforcement and procurement policy are pulling the world’s two AI supply chains apart.

Two readings for markets

For investors watching the semiconductor cycle, the indictment carries two opposing implications — and neither amounts to a recommendation.

The bullish reading is that enforcement protects the integrity of the U.S. tech ecosystem. Tighter control over advanced hardware safeguards the value of domestic AI investment, supports the compliance premium of legitimate supply chains, and reinforces the policy backdrop behind U.S. fab and AI-infrastructure spending. Demand for AI compute itself is unaffected by a smuggling case — if anything, confirmed diversion attempts underscore how badly the hardware is wanted.

The bearish reading focuses on exposure and escalation. Nvidia’s China business is already shrinking under tightening controls, and heightened scrutiny of Southeast Asian transit routes — the alleged corridors of this scheme — raises compliance costs and the risk of disruption for legitimate trade through the region. Enforcement actions can also invite retaliation: Beijing has been steering state-linked firms toward domestic chips, and each new U.S. action adds momentum to China’s import-substitution drive, which analysts say is already reshaping market share in China’s AI hardware market.

The net effect is a geopolitical risk premium layered on top of a fundamentally demand-driven cycle. Chip stocks are being priced not only on data-center orders and product roadmaps, but on the trajectory of U.S.-China tech policy — a variable no earnings report controls.

What to watch next

Several developments will determine whether this case is a headline or a turning point. First, the court proceedings themselves: further indictments of alleged co-conspirators or transshipment intermediaries would signal how far prosecutors intend to reach into the diversion networks. Second, the export-license review that U.S. lawmakers are demanding — if Commerce tightens the review standards or the 25% tariff and volume-cap regime applied to certain AI chips, compliant sales to China could shrink further. Third, Nvidia’s own response, including what its executives say about China demand and compliance on future earnings calls. And finally, the broader U.S.-China technology negotiations, where chips have become a bargaining chip in their own right.

The $300 million question is not whether AI demand justifies the hardware — it clearly does — but who gets to buy it, under what rules, and at what cost to the companies caught between Washington’s controls and Beijing’s procurement.
