OpenAI's revenue is $20 billion lower than investors believed

OpenAI's annualized revenue is approximately $50 billion, not the $70 billion previously reported, according to the Financial Times. The earlier figure was based on information the company shared with investors. The discrepancy stems from differing calculation methods. Anthropic includes revenue from cloud partners like Amazon Web Services, while OpenAI excludes it. Investors calculated OpenAI's July revenue at $40 billion, but it was actually around $30 billion, before a 70 percent growth rate was applied. The correction matters because investors use these figures to compare AI labs and justify massive investments in the technology. OpenAI did not dispute the initial $70 billion estimate, which media reported last month.
