Anthropic Surpasses OpenAI in Revenue but Loses Customers to Rival's Discounts

Anthropic achieved a historic milestone in October 2026 by reporting higher quarterly revenue than OpenAI, yet the company's strict pricing approach is triggering a customer exodus to its rival. Anthropic generated $16.8 billion in third-quarter revenue, representing 45% growth from the prior quarter, according to internal documents reviewed by the press. OpenAI, by comparison, has revised its 2026 revenue projection downward to $50 billion, well below earlier expectations of $70 billion.
