# Mercor

> AI expert-talent and model-evaluation platform; its last company-announced priced round was a $350M Series C at $10B in October 2025, with a higher 2026 valuation reported but not company-confirmed.

## Why it is interesting

Mercor supplies expert human judgment used to train and evaluate frontier AI systems, making it a high-growth but customer-concentrated infrastructure business. Its 2025 $10B company-announced mark must be distinguished from reported 2026 talks around $20B; the size and close of any later priced round are not confirmed by its own announcements.
