Self-Reliance on Paper, Acquisition in Practice: How official chip bans on both sides coexist with a documented, multi-billion-dollar acquisition pipeline

Watch what Beijing does, not what it says. Officially, the wall is up: Beijing has layered its own restrictions on top of U.S. export controls, blocking Nvidia’s H20/H200 on a case-by-case basis and banning workaround cards like the RTX 5090D V2, while pushing state-funded data centers toward Huawei’s Ascend chips. But a September 2026 investigative report from Tom’s Hardware, built on a public-records investigation by the U.S.-funded nonprofit C4ADS titled “Covert Compute,” lays out in granular detail just how porous that wall actually is, and how much bigger the real numbers are than earlier reporting suggested.

Three Channels, Wildly Different Scales

The Tom’s Hardware writeup of the C4ADS report identifies three distinct smuggling pathways, and the dollar figures across them aren’t remotely comparable, which is itself the story. The report cautions that these are only the chips explicitly identified in the records; the real total is likely higher, and a separate estimate from Epoch AI, cited in the same Tom’s Hardware piece, puts as much as a third of China’s entire AI compute stock on smuggled hardware.

Route 1: University and research-institution purchases

Chinese universities and research institutes buy Nvidia GPUs by burying them inside “sprawling multi-vendor contracts” routed through small regional integrators. The Tom’s Hardware report notes some buyer institutions have ties to China’s defense and intelligence sectors. C4ADS tracked 56 chips worth $1.7 million moving this way between July 2025 and January 2026 alone, on top of $6.48 million identified in an earlier multi-year filing.

Route 2: Southeast Asia drop-shipping

This is technically legal on paper: hardware is routed through Vietnam, India, and Malaysia. Vietnam’s chip-testing facilities offer a plausible cover story for the transit. The Tom’s Hardware report cites $13.4 million in Nvidia A100, H100/GH100, and AD102-series GPUs moved this way between 2022 and 2025, in what C4ADS calls a “consistent pattern.” A portion of that hardware continues on to Hong Kong, where two firms, Profit New Limited and ELB International Limited, dominate the import side; Profit New alone moved $8.7 million of silicon in a single day in March 2025, timed just ahead of that April’s tightened export controls.

Route 3: Shell companies, a different order of magnitude

This is where the $4.6 billion figure comes from, and the Tom’s Hardware/C4ADS report names the entity directly: Megaspeed International, the largest Southeast Asian importer of Nvidia hardware between 2023 and 2025. Its ownership is, in the report’s own word, “unresolved”:

Two things stand out from that chain. First, the trail keeps circling back to the same person even after formal ownership “changes.” Second, per Bloomberg reporting cited in the Tom’s Hardware article, Megaspeed reportedly obtained export-locked Blackwell chips, the newest, most tightly restricted Nvidia hardware category, despite the corporate fog around who’s actually running it.

What C4ADS Recommends, and Why It’s Hard

The Tom’s Hardware report also covers C4ADS’s proposed fixes: more staffing and resources for the U.S. Bureau of Industry and Security to verify end-users after a sale actually closes, and a push for chipmakers and distributors to build real due-diligence programs, including corporate ownership tracing, on-the-ground verification, and post-shipment checks, that go beyond simply screening names against a restricted-party list. The report itself flags the obvious catch: this level of verification requires cooperation from foreign jurisdictions (Singapore, Hong Kong, Vietnam) that may have limited appetite for it in the current political climate.

The Other Leaks: A Different Kind of Chip, and a Different Kind of Theft

Two more data points round out the picture, neither captured in the C4ADS report but consistent with its thesis that enforcement gaps exist wherever incentives are large enough:

• Defense-surplus arbitrage. Semiconductor analyst Dylan Patel has pointed out that AMD chips built for U.S. military use, list price around $36,000, sold to defense contractors at $4,000–5,000 at volume, have reportedly turned up quoted at roughly $1,000 in China through crowdfunding-style campaigns. It’s a fourth leakage point the smuggling-network framing doesn’t cover: inefficient defense-procurement pricing creating its own export loophole.
• Know-how theft, not just hardware. On the “memory wall” side, South Korean prosecutors have brought multiple cases of SK Hynix and Samsung personnel allegedly funneling HBM and advanced-packaging know-how to Huawei’s HiSilicon unit, including one suspect arrested boarding a flight to China after citing stolen documents in a HiSilicon job application. If China can’t buy or smuggle enough HBM, stealing the process knowledge to build a domestic substitute faster is the fallback.

Brass Tacks

Every route (a shell company’s suitcase-sized rack, a university’s multi-vendor contract, a defense-surplus chip, a stolen packaging document) exists for the same reason: China’s domestic stack isn’t yet good enough to carry frontier AI development alone. What the Tom’s Hardware/C4ADS report adds is scale and specificity: it names Megaspeed, quantifies each channel, and shows that the $4.6 billion figure isn’t a rough estimate but a documented, if murky, corporate paper trail. Export controls have clearly raised the cost of staying in the race. They haven’t produced a blockade.
