Anthropic's run-rate revenue crossed $47 billion in May 2026, up from $30 billion in April

3 Key Points

  1. Anthropic announced a $65 billion Series H funding round on 29th May 2026. In the announcement, the company stated that its run-rate revenue crossed $47 billion earlier that month, up from approximately $30 billion at the end of April.

  2. Run-rate revenue is an annualized projection calculated by taking the most recent month's revenue and multiplying by 12. Anthropic has shared this metric in multiple fundraising announcements: $14 billion in February 2026 (Series G), $30 billion in April 2026, and $47 billion in May 2026.

  3. According to Axios CEO Jim VandeHei (quoted in the article), no company in any industry or era has scaled organic revenue this quickly at this level, a statement made when Anthropic's run-rate was $30 billion.
