Anthropic's annual revenue has reached nearly $45 billion, surpassing OpenAI's estimated $33 billion by at least 35%, according to ChainCatcher. This marks a significant shift from the end of 2025 when Anthropic's revenue was approximately $9 billion, less than half of OpenAI's. Since then, Anthropic's revenue has grown about fivefold, while OpenAI's has increased by around 50%.
Anthropic's growth is primarily driven by enterprise-level AI, code generation, and white-collar work applications, potentially achieving quarterly operational profitability. In contrast, OpenAI continues to face high computational and consumer business costs.
