OpenAI's annualised revenue is approaching $70 billion. That is up more than 70% since the quarter began, against roughly $40 billion reported a month earlier. Business revenue more than doubled over the same period. Consumer revenue in the third quarter alone beat all of 2025. OpenAI credits subscriptions, enterprise demand, Codex and a new advertising business. The figure landed alongside DevDay and while Anthropic's own prospectus was being reported. Neither company has published audited accounts.
