Docs: US data labeling companies, like Surge AI and Mercor, that sell training datasets to US AI labs and the government are also selling them to Chinese labs (Anna Tong/Forbes)
↗
US data-labeling firms such as Surge AI and Mercor are providing the same training datasets to Chinese AI laboratories that they sell to domestic AI labs and government agencies.
Engineers building or fine-tuning models must now consider that the raw annotation data they rely on may be simultaneously available to competitors abroad, raising concerns about intellectual-property leakage and compliance with export-control rules. The dual-market supply chain also forces organizations to audit vendor contracts and possibly redesign data-ingestion pipelines to satisfy security policies.

Surge AI and Mercor, which already supply labeled data to US AI developers and the federal government, are also selling those datasets to Chinese AI labs.
The overlap creates a shared data pool between US and Chinese research efforts, potentially eroding competitive advantage for US-based model developers.
Companies using these datasets may need to implement additional compliance checks, licensing reviews, or alternative data sources to meet export-control and security requirements.
THE READ
What the cluster adds up to.
The primary shift is the expansion of the customer base for US-based data-labeling vendors to include Chinese AI laboratories. Previously, the same firms were known to serve only domestic AI developers and government customers, but documentation now shows they are extending the same training datasets abroad. This change means that the raw annotation assets that underpin many US models are no longer exclusive to the domestic ecosystem. Engineers who integrate these datasets into model training pipelines must now assess the risk of shared data exposure. If a model’s performance gains rely on proprietary labeling conventions, the parallel availability of those labels to foreign competitors could diminish any competitive edge. Moreover, the presence of the same data in both US and Chinese contexts may trigger export-control scrutiny, especially for projects involving sensitive technologies. From an operational standpoint, teams will likely need to augment their vendor management processes. This could involve adding contractual clauses that restrict re-export, conducting regular audits of data provenance, or switching to alternative labeling providers that enforce stricter geographic
