Eight months ago, Mercor was worth $10 billion. Now it’s in talks that could double that figure to $20 billion, according to Bloomberg. For a company founded by three college dropouts in 2022, that trajectory is the kind that makes venture capitalists cancel their weekend plans.
Mercor connects major AI labs with domain experts, think doctors, lawyers, financial analysts, and media professionals, to generate high-quality training data for machine learning models. The business is simple in concept and lucrative in practice: AI companies need humans who actually know things, and Mercor supplies them at scale.
The numbers behind the valuation
Mercor raised $350 million in a Series C round in October 2025, vaulting its valuation from $2 billion to $10 billion in a single step. That earlier round, the Series B, had closed in February 2025. So the company went from a $2 billion valuation to discussions around $20 billion in roughly eight months.
Total funding raised since the company’s founding now exceeds $490 million.
