Anthropic’s Workforce Grew More Than Fivefold to 5,300 by Sept. 30

Anthropic had about 5,300 employees on Sept. 30, more than five times its roughly 940 employees at the end of 2024, as revenue per employee climbed above $6.6 million.

The revenue-per-employee figure covers the 12 months through Sept. 30, 2026. It was $1.4 million a year earlier. The measure compares company revenue with its workforce; it is not employee pay.

Anthropic’s revenue for the first half of 2026 reached $16.29 billion, a 1,304% increase from the same period a year earlier. That six-month total covers a different window from the trailing 12-month revenue-per-employee measure.

Claude models produced more than 90% of the company’s codebase contributions in September 2026. Anthropic also had hundreds of open positions, with recruiting continuing alongside the reported growth in its workforce.
