China is about 2 percent of Mercor's quarterly revenue; the naming reaches the enterprise customers the round was raised to win. ## A $500 million market nobody had priced On November 11, ChinaTalk, a China-policy newsletter, [published an investigation](https://lapaasvoice.com/us-data-brokers-are-selling-500-million-in-ai-training-data-to-chinese-labs-raising-security-concerns/) by Aqib Zakaria and Quinn Ennis into US vendors selling training data and reinforcement-learning environments to Chinese AI labs, a market it sizes at roughly $500 million [1]. It names at least nine companies [1]. An RL environment is a simulated workplace where a model attempts a task, fixing a bug in real code, and is scored until it improves [2]. The report says [Alibaba](https://theinference.org/markets/companies/alibaba), the Chinese internet group, bought software-engineering environments from [Mercor](https://theinference.org/markets/companies/mercor), a marketplace that pays a network of more than five million human experts to train and evaluate AI models [5][6]. [Surge AI](https://theinference.org/markets/companies/surge-ai) supplied [Tencent](https://theinference.org/markets/companies/tencent), Z.ai and Moonshot AI, whose Kimi K3 model is rated a match for US systems at programming; Turing sold to Tencent and Alibaba [1][2]. The same vendors supply [OpenAI](https://theinference.org/markets/companies/openai) and [Anthropic](https://theinference.org/markets/companies/anthropic), and where a frontier lab's confidentiality blocks a resale, they offer to rebuild the set with the same experts [2]. AfterQuery is the extreme case: about $100 million in annual recurring revenue, roughly half from Chinese customers, per Forbes, a figure ChinaTalk could not independently verify [6]. ## One day too late for the round The report landed one day after Mercor closed a $750 million Series D at a $20 billion valuation, with [Nvidia](https://theinference.org/markets/companies/nvidia), [Salesforce](https://theinference.org/markets/companies/salesforce) and [Zoom](https://theinference.org/markets/companies/zoom) among the named buyers, double its $10 billion mark of October 2025 [4][5]. (The Inference [profiled the round](https://theinference.org/article/mercor-raises-750-million-at-20-billion-on-a-tasker-network-paying-2-to-10-an-hour) on November 11 [4][5].) The direct cash at risk is small: Forbes put Chinese buyers at about 2 percent of Mercor's second-quarter 2026 revenue [6]. The commercial exposure is larger. Mercor raised the money to expand evaluation and post-training services for enterprises [4][7], and rivals Scale, micro1 and Fleet publicly refuse business with Chinese customers [6]. Neither Mercor's [round announcement](https://www.mercor.com/blog) [7] nor chief executive Brendan Foody's [CNBC interview](https://www.cnbc.com/video/2026/11/10/mercor-ceo-brendan-foody-on-nvidia-investment-ive-met-with-jensen-huang-a-variety-of-times.html) that morning [8] addressed the China sales; CNBC billed the interview around the scandal then surrounding Nvidia's chief, [Jensen Huang](https://theinference.org/markets/people/jensen-huang), who has since resigned after The New York Times reported on October 29 that he appeared to be the target of a Chinese spy plot [9]. *Chart: **Mercor's new mark is 40 times the whole China data market** Bar chart comparing ChinaTalk's estimated $500 million US-to-China training data market against Mercor's $750 million Series D round and $20 billion valuation* *ChinaTalk's estimate of US training-data and RL-environment sales to Chinese labs, against Mercor's Series D round and post-money valuation, November 10 to 11, 2026, US dollars. Sources: ChinaTalk as reported [1]; Casrai [5]. [1][5]* ## Export controls cover chips, not training software The sales break no US rule [6]. RL environments mostly fall under EAR99, the export classification that needs no license unless the buyer is sanctioned, as the Chinese lab Zhipu is [6]. Washington restricts the advanced chips China cannot buy and leaves the training software ungoverned [6]. ChinaTalk asks the Commerce Department's Bureau of Industry and Security to treat coding and biology environments as dual-use goods, products with both civilian and military applications, and to restrict their export [1][6]. The report carries its own counterweight: the sales are not proof of wrongdoing, Chinese labs remain months behind their US rivals, and US frontier labs are pulling their most sensitive environments in-house, the very revenue outside vendors sell [1][6]. Two readings decide the next quarter: whether Mercor states a China policy before enterprise customers ask, and whether the Bureau of Industry and Security begins a rulemaking. ## Takeaway A roughly $500 million market for AI training data now has a $20 billion company named in it, and no US export rule covers the trade. ## Sources 1.
