Reports put OpenAI's annualized revenue near $50 billion, about $20 billion under an earlier figure. The gap is less about sales collapsing and more about how two companies count.
OpenAI's Revenue Reportedly Comes In $20 Billion Below Estimates
OpenAI has told investors its annualized revenue is "approaching $50 billion," according to the Financial Times, a figure TechCrunch and Axios reported on October 8. A little over a week earlier, media reports had put the same number near $70 billion. The roughly $20 billion gap between those two figures is the story. The reason is more about accounting than about demand falling off a cliff.
It's worth stating plainly what this is. The lower figure comes from financial documents OpenAI shared with investors, as reported by the FT. OpenAI hasn't confirmed either number in public, and TechCrunch said the company didn't respond to a request for comment. Treat the $50 billion as reported, not official. Simple as that.
Why OpenAI and Anthropic Revenue Numbers Don't Line Up
The $70 billion figure wasn't a solid measurement. According to the FT, it came from investors' attempts to build a direct comparison with Anthropic's annualized revenue. That's a derived number, not a reported one, and it was always going to be shaky.
The bigger issue sits underneath: OpenAI and Anthropic don't count revenue the same way. Anthropic includes sales made by its cloud partners in its annualized revenue. OpenAI doesn't. Play that difference forward and any head-to-head comparison between the two companies gets muddier, because they're measuring different things with the same word.
So the "miss" isn't a simple case of OpenAI selling less than it thought. It's a case of a number built for comparison, then corrected when the comparison itself looked wrong. Same word, different math. Anyone comparing the two labs on revenue alone should slow down, because the definitions underneath the numbers aren't the same.
The Funding and IPO Context Behind the Reported OpenAI Revenue
The revenue question carries more weight for OpenAI than for most companies, because of what's riding on it.
OpenAI raised $122 billion in a single funding round in March, according to the company. That's an enormous amount of capital to justify, and revenue is the number investors lean on to check whether the spending pays off. A lower revenue figure makes that math harder, at least on paper.
There's also history here. Leaked 2025 financials, reported earlier this year, showed OpenAI bringing in about $13 billion while spending significantly more. The company's IPO, once rumored for this year, has been pushed to early 2027. That makes the OpenAI IPO timeline a live question for anyone tracking the company's finances. For an outfit spending ahead of its income, every revenue revision gets read through the lens of when the bills come due.
None of this means OpenAI is in trouble. It means the story investors are being asked to buy, that annualized revenue was racing toward Anthropic's, is more complicated than a single number suggested. One headline isn't a business.
What the Revenue Revision Means for AI Funding
The takeaway for anyone watching the AI money race is that headline revenue figures are shakier than they look.
When two of the biggest names in AI report "annualized revenue," they can mean different things, and a comparison built on top of that can move by billions without a single customer changing their behavior. The $20 billion gap is real in the reporting, but it's a gap in measurement as much as in sales.
For developers and businesses, this changes little day to day. The models keep shipping, the prices keep moving, and the API you build on works the same whether the parent company's run rate is $50 billion or $70 billion. What it does change is how seriously to take the next revenue headline you see. Ask what's being counted, and by whom, before you treat it as a scoreboard.
The next checkpoints are the ones to watch: whether OpenAI confirms a figure itself, how its IPO timing firms up, and whether the two labs ever settle on a shared definition of annualized revenue. Until then, treat any direct OpenAI-versus-Anthropic revenue comparison as a rough sketch rather than a photograph.
