Claims
- Anthropic's run-rate revenue crossed $47 billion in May 2026, rising from $30 billion in April and $14 billion in February 2026.
- Run-rate revenue is an annualized projection calculated by multiplying the most recent month's revenue by 12, not a trailing annual figure.
- Anthropic's reported revenue figures are credible because misrepresenting them to Series H investors would constitute securities fraud.
- An anonymous AI consultant told Axios that one client spent half a billion dollars in a single month on Claude licenses after failing to set usage limits.
