**[OpenAI's Annualized Revenue Exceeds $25 Billion, Anthropic Catches Up with $19 Billion]** BlockBeats News, March 5: According to a report by *The Information*, as of the end of February 2026, OpenAI's annualized revenue has exceeded $25 billion. OpenAI's Chief Financial Officer, Sarah Friar, confirmed in an official blog post and multiple reports in January 2026 that the company's annualized revenue for 2025 had surpassed $20 billion, approximately tripling from $6 billion in 2024. However, some subsequent publicly disclosed investor information revealed that OpenAI's actual full-year revenue for 2025 was approximately $13.1 billion, higher than the company's early target of $10 billion but lower than the peak annualized estimate of $20 billion. After rapid growth in the first half of 2025, OpenAI experienced a slowdown in growth in the second half of the year. Media outlets such as CNBC estimated that its mid-2025 annualized revenue was around $10 to $13 billion, while its year-end annualized revenue was approximately $5.5 billion. In contrast, OpenAI's direct competitor Anthropic saw its mid-2025 annualized revenue at around $4 billion, which quickly surged to approximately $9 billion by the end of the year, driven by the explosive growth of enterprise clients and products like Claude Code. As of early March this year, Anthropic's latest annualized revenue has already exceeded $19 billion. Currently, Claude Code's run rate has surpassed $2.5 billion, with over 500 clients spending more than $1 million annually. The gap between Anthropic and OpenAI is narrowing.
