OpenAI's annualized revenue run rate exceeded $40 billion in August 2026, doubling from $20 billion at the end of 2025.
This rapid growth is fueled by revenue streams from Codex (its AI coding software), subscription sales, and a newly launched advertising business.
Co-founder Greg Brockman highlighted a monthly revenue growth rate exceeding 20% in July 2026.
These metrics showcase aggressive scaling ahead of OpenAI's anticipated IPO.
Meanwhile, competitor Anthropic shows similar momentum, with a $47 billion run rate as of May 2026 and projections to reach $100-120 billion by year-end.
