Greg Lui, the 38-year-old owner of California computer supplier Earthmade Computer Inc., has been arrested on federal charges alleging he smuggled more than $300 million worth of export-controlled Nvidia AI servers into China. The case, announced by the Department of Justice on Thursday, puts a fresh spotlight on the weakest link in Washington's effort to keep America's most advanced semiconductors out of Beijing's hands — and gives semiconductor investors another reason to watch export-control enforcement closely.
Prosecutors say Lui, also known as "Yiu Kong Lui," of San Gabriel, California, used false paperwork and shipments through third countries to move high-end servers packed with restricted Nvidia H100 graphics processing units (GPUs) to China between 2023 and 2024. The indictment was unsealed after federal agents raided his company's headquarters in the City of Industry, and it ranks among the largest single-defendant export-control cases ever brought against a U.S. technology supplier.
How the Alleged $300 Million Nvidia Smuggling Scheme Worked
According to the three-count federal indictment, Lui and unidentified co-conspirators used Earthmade Computer Inc. to buy export-controlled computer servers containing Nvidia AI chips directly from U.S. manufacturers. Prosecutors allege the company then filed false paperwork that concealed the true end-users of the equipment, declaring buyers in locations where the shipments would not face the same restrictions.
Once the servers were purchased, authorities say Lui routed them through third countries — most notably Malaysia and Singapore — using freight-forwarding companies. After the hardware arrived overseas, it was reshipped onward to China without the required export licenses, according to the DOJ. Court documents cited in multiple reports indicate workers at U.S. warehouses would rebrand or relabel the equipment to further obscure its final destination.
Prosecutors claim Lui received more than $176 million in payments from two Malaysian transshipment companies, and the United States has seized over $50 million in Nvidia technologies and cash tied to the investigation. "This defendant allegedly used false paperwork and shipments through third countries to smuggle more than $300 million in export-controlled" technology, the Department of Justice said in announcing the charges. First Assistant United States Attorney Bill Essayli was blunt about the stakes: "We will aggressively prosecute those who put our national security at risk for profit."
The FBI, which investigated alongside the Commerce Department's Bureau of Industry and Security, said its probe revealed that Lui allegedly sold the Chinese government hundreds of millions of dollars' worth of American supercomputing hardware — the advanced computer chips that make modern AI possible. Assistant Attorney General for National Security John A. Eisenberg framed the case in strategic terms, describing artificial intelligence as "the defining technology of the era" and vowing that the United States would defend its leadership in the field.
The Charges and the Potential Penalties
Lui faces a three-count federal indictment: one count of conspiracy to violate the Export Control Reform Act and the Export Administration Regulations, one count of outbound smuggling, and one count of money-laundering conspiracy. If convicted on all counts, the statutory maximums stack up quickly — up to 20 years in prison for the export-control conspiracy, up to 20 years for the money-laundering charge, and up to 10 years for outbound smuggling, for a combined maximum of roughly 50 years.
Prosecutors have stressed that the charges are allegations and that Lui is entitled to a presumption of innocence. He was taken into custody Thursday and was expected to make an initial appearance and be arraigned Friday in United States District Court in Los Angeles.
Timeline: From 2023 Purchases to the October 2026 Arrest
- 2023–2024: Lui and co-conspirators allegedly use Earthmade Computer to buy export-controlled servers containing Nvidia chips from U.S. manufacturers, file false end-user paperwork, and route shipments through Malaysia and Singapore before sending them to China.
- 2024–2025: U.S. authorities separately uncover a wave of related smuggling, including reports that at least $1 billion worth of Nvidia AI chips reached China in early 2025 despite export curbs.
- March 2026: Lawmakers demand the Commerce Department suspend Nvidia's licenses to ship advanced chips to Southeast Asia, and three men face charges in Singapore over a related Nvidia chip-smuggling network.
- October 1, 2026: Federal agents arrest Lui in a raid at his company headquarters, and a federal grand jury's indictment is unsealed.
- October 2, 2026: Lui is arraigned in Los Angeles federal court.
Why This Matters for Nvidia and Semiconductor Investors
The arrest is the latest in a string of enforcement actions that have turned export controls into a genuine risk factor for chip stocks. Nvidia's advanced GPUs remain the backbone of AI infrastructure worldwide, but U.S. restrictions have made them a high-value target for smugglers — and each new indictment raises uncomfortable questions about how effectively the supply chain is being policed.
Bloomberg reported this week that officials are asking why Nvidia and other manufacturers missed red flags as their chips kept reaching China despite the curbs. Senator Elizabeth Warren has probed Nvidia's compliance with export-control laws, and earlier this year lawmakers called on the Commerce Department to suspend Nvidia's licenses to export AI chips to Southeast Asia — the very route prosecutors say Lui exploited.
For investors, the implications cut two ways. On one hand, aggressive enforcement signals that Washington is serious about closing smuggling loopholes, which could eventually tighten the flow of AI chips reaching restricted markets. On the other, a widening enforcement net creates headline risk for Nvidia and its server-making partners, and it raises the possibility of stricter licensing requirements that could slow legitimate sales growth across Asia.
The case also underscores a structural reality of the AI chip trade: even with export bans in place, determined intermediaries have repeatedly moved Nvidia hardware to China through Singapore, Malaysia, Taiwan, and Thailand. Earlier crackdowns — including the seizure of a $42 million home in Singapore and charges against a Super Micro co-founder — have yet to fully close the gap, keeping regulatory risk on the radar for anyone holding semiconductor stocks.
Where the Case Stands Now
Lui remains in federal custody following his arrest and arraignment in Los Angeles. The Justice Department has not named the co-conspirators described in the indictment, leaving open the possibility of additional charges or arrests as the investigation continues. The case is being prosecuted by the U.S. Attorney's Office for the Central District of California, with support from the National Security Division's Counterintelligence and Export Control Section.
The DOJ has signaled that export-control enforcement against advanced AI hardware is a top priority, and officials have framed the Lui case as part of a coordinated effort to protect American technological supremacy. Authorities have not alleged wrongdoing by Nvidia itself, and the company has not been charged in connection with the scheme.
What Happens Next for the Case — and for the Chip Trade
The immediate next step is pretrial proceedings, where prosecutors will begin disclosing evidence and the defense will have an opportunity to challenge the indictment. Given the scale of the alleged scheme and the unnamed co-conspirators, the case is likely to produce further developments in the months ahead.
More broadly, the Lui arrest is likely to intensify scrutiny of the entire AI chip supply chain. Investors should watch for new export-control enforcement actions, tighter compliance requirements for chipmakers and server manufacturers, and any policy response from Washington aimed at closing the third-country transshipment loopholes that prosecutors say made the alleged scheme possible.
Key Takeaways
- Greg Lui, 38, owner of Earthmade Computer Inc., was arrested October 1, 2026, on a three-count federal indictment alleging he smuggled more than $300 million in Nvidia AI servers to China.
- Prosecutors say he used false end-user paperwork and shipped servers through Malaysia and Singapore before routing them to China without the required licenses.
- Lui faces up to roughly 50 years in prison across charges of export-control conspiracy, outbound smuggling, and money-laundering conspiracy.
- The case is part of a broader enforcement wave against AI chip smuggling that has kept export controls — and Nvidia's supply chain — squarely in focus for semiconductor investors.
