Mercor eyed at $20B valuation

Mercor is in discussions for a new funding round that would value the AI training startup at about $20 billion, according to Bloomberg’s AI coverage page on July 9. Bloomberg’s listing did not disclose the size of the round, prospective investors or whether terms were finalized. The San Francisco company last announced financing on Oct. 27, 2025, when it said it raised $350 million in a Series C led by Felicis at a $10 billion valuation. Benchmark, General Catalyst and Robinhood Ventures also participated, according to Mercor. Mercor has positioned itself as a supplier of human expertise to AI labs and enterprises, saying it connects specialists with model builders and that its network helps train frontier systems. (bloomberg.com) Chief Executive Brendan Foody wrote in the company’s Series C post that Mercor sits “at the intersection of labor markets and AI research.” ### Why would a company valued at $10 billion less than a year ago be discussing $20 billion now? (mercor.com) Mercor said in February 2025 that it was growing more than 51% month over month and focused on contracting experts to help advance AI systems. In October 2025, the company said its Series C valued it at five times its Series B valuation, showing how quickly investors had already repriced the business. (mercor.com) Crunchbase said global startup investment reached a record $510 billion in the first half of 2026, with capital concentrating in AI, infrastructure and other large late-stage deals. That backdrop helps explain why investors have continued to back companies tied to model development and deployment. ### What does Mercor actually sell to AI companies? (mercor.com) Mercor said in its October 2025 financing announcement that it connects “human expertise” with leading AI labs and enterprises and that professionals use the platform to teach models judgment, context and domain knowledge. The company described examples including doctors, bankers and lawyers helping improve model performance in specialized work. (news.crunchbase.com) TechCrunch reported in 2025 that Mercor connects companies including OpenAI and Meta with domain experts needed to train and refine foundational AI models. Bloomberg described Mercor in an April 2026 video as a startup hiring high-skilled workers to teach AI how to do their jobs. ### Who has backed Mercor so far? (mercor.com) Felicis has led Mercor’s last two announced rounds. Mercor said its $100 million Series B in February 2025 included General Catalyst, DST Global Partners, Benchmark and Menlo Ventures, and its $350 million Series C in October 2025 added Robinhood Ventures. Mercor also said its team included the former head of human data operations at OpenAI and the previous head of growth at Scale, underscoring the company’s focus on recruiting and managing specialized labor for AI work.

Meta paused work with Mercor after a data breach, Business Insider reported in April 2026, citing a person familiar with the matter. (mercor.com) Mercor told the publication it had been affected by a security incident linked to a supply-chain attack involving LiteLLM and said third-party forensic experts were supporting its investigation. That episode showed that Mercor’s business depends not only on demand from AI labs but also on maintaining customer trust around contractor and client data. Meta declined to comment to Business Insider at the time. ### What should readers watch for next? Bloomberg’s July 9 posting indicates the talks are current, but no financing documents, investor commitments or company statement were publicly available in the materials reviewed. (africa.businessinsider.com) Mercor’s next concrete milestone would be a formal funding announcement naming the round size, valuation and participating investors. (bloomberg.com)
