OpenAI annualized revenue is $50 billion — $20 billion below the reported $70 billion
On October 8, 2026, the Financial Times reported that OpenAI had told investors its annualized revenue was approaching $50 billion at the end of September, about $20 billion less than the roughly $70 billion several outlets had reported a week earlier from investor information. The difference is mostly a counting method. Anthropic includes the full value of sales made through cloud partners like AWS and Google Cloud in its revenue; OpenAI excludes them, and investors trying to compare the two on the same basis produced the larger figure. OpenAI's growth remained strong, above 70% in the third quarter, but the Nasdaq Composite fell 1.25% to 27,193.34 that day, led by chip and data-center stocks
The three lines
- Number — ~$50B annualized at end-September, vs ~$70B reported in late September
- Why — Anthropic counts cloud-partner sales, OpenAI doesn't; investor estimates spread
- Market — Nasdaq −1.25% on Oct 8, Nvidia −2.94%; Korea's market reacts on Oct 12
Key questions
- OpenAI annualized revenue 2026
- **About $50 billion at the end of September 2026 (investor figure, reported by the FT).** | Period | Annualized revenue | Source | |---|---|---| | August 2026 | Over $40B | Bloomberg-cited reports | | End-Sept 2026 (estimates) | ~$68B–70B | Axios, CNBC and others | | **End-Sept 2026 (company figure)** | **~$50B** | FT (Oct 8), confirmed by CNBC |
- Why OpenAI revenue $50 billion not $70 billion
- **Whether cloud-partner sales count as revenue.** | Item | Anthropic | OpenAI | |---|---|---| | Sales via AWS, Google Cloud | Counted in full (gross) | Excluded | | The $70B figure | — | Investor estimate on Anthropic's basis | | Method (reported) | — | Earlier $40B estimate grown by ~70% |
- What is annualized revenue run rate
- **Recent monthly (or quarterly) revenue scaled up to a full year.** | Item | Detail | |---|---| | Formula | Latest month × 12 (or quarter × 4) | | Used by | Fast-growing subscription and API businesses | | Strength | Shows growth speed immediately | | Limits | Not actual annual revenue; definitions differ by company |
Growth didn't slow; the counting method differed. The market still read the gap as a disappointment for a day. On October 8, 2026, the Financial Times reported that OpenAI had told investors its annualized revenue was nearing $50 billion at the end of September. Barely ten days earlier, several outlets had cited investor information to say it was "approaching $70 billion." The Nasdaq Composite fell 1.25% to 27,193.34, with AI chip and data-center stocks hit hardest.
1. Where the $20 billion went: gross versus net
The gap comes from who books the revenue when an AI model is sold through a cloud company.
| Item | Anthropic's method | OpenAI's method |
|---|---|---|
| Sales made by AWS, Google Cloud and other partners | Counted in full as its own revenue | Not counted |
| Effect | Bigger number | Smaller number |
| Latest figure | $65B at end-July (to investors) | ~$50B at end-September (to investors) |
According to the FT and CNBC, the $70 billion figure never came from OpenAI. Investors trying to compare the two companies on one basis applied OpenAI's roughly 70% growth to an earlier $40 billion estimate. A CNBC source said the $68 billion figure included partners' gross revenue to allow a direct comparison with Anthropic. On a like-for-like basis, OpenAI's $50 billion is below the $65 billion Anthropic reported for the end of July. The same accounting question came up when Anthropic first passed OpenAI in quarterly revenue in August.
2. October 8 in New York: AI infrastructure took the hit
| Item | Close / change, Oct 8 (U.S.) |
|---|---|
| Nasdaq Composite | 27,193.34 (−345.35, −1.25%) |
| S&P 500 | 7,765.36 (−0.47%) |
| Dow | 51,231.64 (+0.10%) |
| Nasdaq 100 | −1.4%, worst day in seven weeks (Bloomberg) |
| Philadelphia Semiconductor Index | Down as much as 4% intraday, −3.4% at close |
| Nvidia | $230.48 (−2.94%) |
| Oracle | −5.5% |
| Arm, Intel, Marvell | Each down roughly 5–6% or more |
| Micron | Down more than 5% |
OpenAI isn't listed, but it is AI infrastructure's biggest customer. Oracle, CoreWeave, Nvidia, Arm and Micron are valued on the assumption that OpenAI's revenue can support compute contracts worth hundreds of billions of dollars. A smaller-looking revenue number shakes that assumption. Baird's Ross Mayfield warned of "tremors throughout all of the related sub-industries." D.A. Davidson's Gil Luria disagreed, saying he was "not concerned about OpenAI just tripling its revenue this year."
3. Growth is still high; expectations moved
| Metric | Figure | Source |
|---|---|---|
| Q3 total run-rate growth | 77% | CNBC (OpenAI investor materials) |
| Q3 enterprise run-rate growth | 107% | CNBC |
| Growth over the period (FT wording) | More than 70% | FT |
| Revenue growth this year | About 3x | Luria, D.A. Davidson |
Nothing in the growth rates shrank. What shrank was the anchor in investors' heads. A market already modeling $70 billion reads $50 billion as a miss even at the same growth rate. Energy added pressure: Brent was near $103 a barrel and WTI near $90, while the U.S. 10-year Treasury yield eased only slightly to about 5.22%.
4. What remains unclear
- Korea's reaction: October 9 is Hangeul Day, a market holiday in South Korea, so the U.S. chip sell-off reaches Seoul on October 12. A day earlier, Samsung Electronics fell 2.42% despite a record quarter (see "Samsung's record 107.4 trillion won profit, yet the KOSPI fell 2.62%").
- No official filing: the $50 billion is an investor figure reported by the FT. OpenAI is private.
- Anthropic's latest: Anthropic's end-September run rate hasn't been disclosed; $65 billion at end-July is the last figure.
- Index close: outlets report 27,193.34 or 27,201.31 for the Nasdaq; this article uses the majority figure.
