Anthropic Revenue Run Rate Hits $65 Billion as Enterprise Concentration Doubles OpenAI's

Anthropic's annual revenue run rate reached $65 billion by end of July 2026, up from roughly $47 billion at end of 2025, per Reuters. Enterprise customers account for 80% of Anthropic's business versus 40% of OpenAI's, according to company executives — a concentration that leaves revenue more exposed to contract-level churn from single pricing or compliance missteps.
