Mercor is reportedly in talks to raise fresh funding at a $20 billion valuation, potentially doubling its worth from its last financing round, according to Bloomberg.

The AI data startup last raised $350 million in a Series C round that valued the company at $10 billion. A new deal at twice that level would underline how strongly investors are still backing companies that help train and improve artificial intelligence models.

Mercor connects AI developers with specialized experts who generate, label and review high-quality training data. Its customers include OpenAI, Anthropic and Meta Platforms NASDAQ:META, giving the company direct exposure to some of the largest AI model builders.

The reported talks come as demand for industry-specific data grows. Advanced models increasingly need expert-generated material in areas such as finance, law, medicine and software development, rather than relying only on broad internet datasets.
