Mercor operates a marketplace: frontier AI labs — OpenAI and Anthropic among them — buy expert human data for model training, and Mercor matches, vets and manages the contractors doing the work. The headline $2B figure is gross annualized revenue, meaning it counts what flows through the platform to contractors; Mercor's net take is estimated closer to ~$600M at roughly 30% gross margins.
The distinction matters when comparing Mercor to peers: $361M of recognized 2025 revenue and $614M in the first half of 2026 are the net numbers. Growth depends on keeping the contractor side elastic — recruiting frontier-domain experts (PhDs, lawyers, bankers) fast enough to feed lab demand for increasingly specialized training data.
