The Shadow Market Behind China’s AI Model Distillation Boom
Chainalysis investigates how a shadow market lets Chinese users bypass U.S. AI export controls via proxy services, finding that 40% of these services accept cryptocurrency. The report highlights a growing, crypto‑enabled ecosystem that could undermine U.S. security restrictions.
Key points
- 40% of surveyed AI proxy services accept crypto, mainly stablecoins.
- Wallet activity linked to China spikes after new U.S. model releases.
- Payments often flow through custodial processors, obscuring the end‑users.
- The proxy supply chain is layered, making disruption difficult.
- Blockchain intelligence can map financial flows to target critical pressure points.
- Proxy services accepting crypto
- 40%

What the report asks
Chainalysis set out to map the emerging “shadow market” that enables Chinese developers to access U.S. frontier AI models despite export bans. The core question is how these proxy services operate, how they are paid for, and whether cryptocurrency plays a role in evading both U.S. restrictions and Chinese capital controls.
Data and methodology
The Global Intelligence Team surveyed 100 AI proxy providers that sell access to models such as Claude, ChatGPT, and Gemini. They examined payment methods, wallet activity, and the broader supply chain, using blockchain analytics to trace crypto flows. The analysis also compared transaction volumes before and after major U.S. model launches to spot anomalous spikes.
Main findings
Chainalysis estimates that 40% of the proxy services accept cryptocurrency, predominantly stablecoins, allowing users to top‑up accounts without using domestic payment rails. Activity from wallets flagged as China‑linked rises noticeably in the days following a new model release, suggesting rapid attempts to acquire fresh capabilities. Payments rarely go directly to the proxy operators; instead, most funds pass through custodial crypto processors, adding a layer of anonymity and reducing exposure to Chinese regulatory scrutiny.
Caveats and limitations
The report stresses that wallet spikes cannot definitively prove the purpose of the payments, nor can blockchain data alone confirm that the funds are used for model distillation. Moreover, the analysis relies on heuristic tagging of wallets as “Chinese‑linked,” which may include false positives or miss covert actors.
