Based on information from sources with inside knowledge, by the end of February 2026, OpenAI's annual revenue had surged past the $25 billion mark. This represents a significant 17% growth from the $21.4 billion it reported at the close of the previous year. At present, OpenAI's revenue still outpaces that of its rival Anthropic. However, the margin is shrinking at a rapid pace, with Anthropic's latest annual revenue having surpassed $19 billion.
