OpenAI's annualized revenue rises to $25 billion, a 17% increase since the end of last year, with Anthropic rapidly catching up

On March 5, it was reported that, according to informed sources, OpenAI’s annualized revenue has exceeded $25 billion as of the end of February 2026, representing approximately a 17% increase from around $21.4 billion at the end of 2025. This growth reflects the ongoing expansion of generative AI products in enterprise services and the developer ecosystem.

Although OpenAI remains the leader, competitors like Anthropic are rapidly catching up. Another insider said that Anthropic’s annualized revenue has recently seen significant growth, and the revenue gap between the two AI companies is gradually narrowing.

Currently, OpenAI’s revenue mainly comes from AI subscription services, enterprise-level large model APIs, and the AI application ecosystem, while Anthropic relies on the Claude series models to accelerate commercialization in AI safety, enterprise AI solutions, and generative AI platforms.

As the business model for large AI models matures, the revenue scale of AI companies continues to grow. The competition between OpenAI and Anthropic is also seen as an important signal of changes in the global generative AI market landscape. (The Information)
