AI company Anthropic's annualized revenue has surged to nearly $45 billion, surpassing OpenAI's estimated $33 billion by at least 35%, according to a report by The Information. This marks a significant turnaround from the end of 2025, when Anthropic's revenue was approximately $9 billion, less than half of OpenAI's. Anthropic's rapid growth is attributed to its focus on enterprise AI, code generation, and white-collar work scenarios, potentially achieving quarterly operating profitability. In contrast, OpenAI continues to grapple with substantial costs associated with computing power and consumer-facing services. While Anthropic's revenue has grown fivefold since the end of 2025, OpenAI's revenue has increased by about 50% during the same period, highlighting the competitive dynamics in the AI industry.
