OpenAI told investors its annualized revenue was nearing $50B at the end of September, which is $20B lower than the $70B figure reported after Dev Day on Sept 29. The Financial Times reported the discrepancy stemmed from investor attempts to compare OpenAI with Anthropic by adding estimated cloud partner sales from providers like AWS and Google Cloud, which OpenAI does not include. Despite the gap, the company's run rate grew more than 70% recently and crossed $40B in August after ending 2025 above $20B.
