OpenAI Statistics 2026: Users, Revenue, and Valuation

ChatGPT now reaches more than 1.2 billion people each week, and the OpenAI statistics below track revenue and funding alongside it. OpenAI closed a funding round with $122 billion in committed capital at a post-money valuation of $852 billion, and it reported generating $2 billion in revenue per month.

The figures below come from OpenAI’s dated announcements, Microsoft’s fiscal 2026 Form 10-K, Pew Research Center surveys and Menlo Ventures’ enterprise report. They cover users, revenue, funding, ownership, enterprise adoption, Codex, API prices and the Stargate compute build-out. Where OpenAI reports a figure about itself, the section names it as a company figure, and Microsoft’s audited filing is the outside check on the money.

Key Takeaways

OpenAI’s compute grew 3 times year over year, or 9.5 times from 2023 to 2025. That pairing explains the funding rounds in the next section: each extra gigawatt has, so far, come with more revenue.

Who Owns OpenAI? Microsoft and the OpenAI Foundation

• OpenAI completed its recapitalization in October 2025; the for-profit is now a public benefit corporation called OpenAI Group PBC.
• The nonprofit OpenAI Foundation held equity then valued at approximately $130 billion, rising to over $180 billion after the February 2026 round.

Why it matters: Microsoft’s 10-K puts its revenue from OpenAI arrangements at $24.1 billion for fiscal 2026, against total funding commitments of $13.0 billion.

Does Microsoft own 27% of OpenAI?

Microsoft said its stake was roughly 27% on an as-converted diluted basis after the October 2025 recapitalization, inclusive of all owners. Its fiscal 2026 Form 10-K describes an approximate 25% interest by June 30, 2026. Excluding the impact of OpenAI’s recent funding rounds, Microsoft held 32.5% of the for-profit on an as-converted basis.

Microsoft will continue to have a license to OpenAI IP for models and products through 2032, now non-exclusive. OpenAI’s revenue-share payments to Microsoft continue through 2030, subject to a total cap.

OpenAI Losses and Gains in Microsoft’s Filings

• Microsoft’s other income included $6.5 billion of net gains from OpenAI investments in fiscal 2026.
• The same line held $4.8 billion of net losses in fiscal 2025.
• The fiscal 2026 gains primarily relate to the dilution gain from the OpenAI Recapitalization.
• The OpenAI result raised Microsoft’s fiscal 2026 net income by $5.0 billion, after cutting fiscal 2025 net income by $3.6 billion.
• Microsoft excludes these OpenAI gains and losses from its non-GAAP adjusted net income, as its fiscal 2026 Form 10-K explains.

How much has OpenAI lost so far?

OpenAI is private and publishes no audited profit-and-loss statement, so its own total loss is not public. Microsoft’s 10-K shows the investment produced net losses of $1,482 million in fiscal 2024 and $4,763 million in fiscal 2025. A $6.5 billion net gain in fiscal 2026 came primarily from the recapitalization’s dilution gain.

OpenAI Business Customers and Enterprise Adoption

• OpenAI passed more than 1 million business customers in November 2025, counting organizations that pay for ChatGPT for Work or the API.
• By July 2026, OpenAI models reached more than two million businesses.
• ChatGPT for Work passed more than 7 million seats in November 2025, and ChatGPT Enterprise seats grew 9x year over year.
• More than 9 million paying business users relied on ChatGPT for work by February 2026.
• Weekly messages in ChatGPT Enterprise increased roughly 8 times over the year to December 2025.
• In OpenAI’s survey of 9,000 workers across almost 100 enterprises, 75% said AI improved the speed or quality of their output.
• Those workers report saving 40-60 minutes per day.
• Over a hundred thousand Oracle employees use ChatGPT Work and Codex.

87% of IT workers reported faster IT issue resolution, the highest of the four role figures OpenAI listed. The figures are self-reported by the 9,000 workers OpenAI surveyed across almost 100 enterprises, so they show perceived gains rather than measured productivity.

Codex and Agentic Work Statistics

• Weekly Codex users more than tripled from the start of 2026 to 1.6 million by late February.
• Codex served over 2 million weekly users by March 2026, up 5x in three months.
• As of June 2026, Codex generated 64% of combined Codex and ChatGPT output tokens among enterprise customers.
• Frontier firms generated 8.3 times as many output tokens per active user as typical firms, up from 2.6 times in January 2026.
• 21% of weekly active users at frontier firms use Plugins, compared with 9% at typical firms.
• Inside OpenAI, agentic work through Codex accounts for 99.8% of weekly output tokens.

Legal posted the largest growth of the five functions OpenAI named, at 108 times, against 5 times in engineering.

How popular is OpenAI compared to other AI tools?

• 44% of US adults use ChatGPT, against 24% for the Gemini chatbot and 17% for Copilot.
• Meta AI reaches 14%, and about one-in-ten or fewer use Grok, Claude or Character.ai.
• Menlo Ventures estimates Anthropic earns 40% of enterprise LLM spend, against 27% for OpenAI and 21% for Google.
• In coding, Menlo estimates Anthropic’s share at 54%, compared to 21% for OpenAI.
• OpenAI says ChatGPT has 6x the monthly web visits and mobile sessions of the next largest AI app.

ChatGPT’s 44% is close to double Gemini’s 24% among US adults. Enterprise spending tells a different story: OpenAI’s share fell from 50% in 2023 to 27% in 2025, while Anthropic rose from 12% to 40%.

Key finding: Menlo Ventures estimates OpenAI lost nearly half of its enterprise share, falling to 27% from 50% in 2023. Pew still finds 44% of US adults use ChatGPT, while about one-in-ten or fewer use Claude. Consumer reach and enterprise API spend are separate races, and OpenAI leads only the first.

How People Use ChatGPT

• About half of consumer messages (49%) are Asking, the largest category in the study.
• Approximately 30% of consumer usage is work-related and approximately 70% is non-work.
• Three-quarters of conversations focus on practical guidance, seeking information and writing.
• Among users whose names could be classified as masculine or feminine, the share with typically feminine names rose from 37% in January 2024 to 52% by July 2025.
• Users who mainly write in a language other than English now represent over half of active users.

The study, an NBER working paper by OpenAI’s Economic Research team and Harvard economist David Deming, analyzed 1.5 million conversations. Asking was the largest category at 49% of messages.

OpenAI API Pricing by Model

• GPT-6 Astra lists at $10 per million input tokens and $50 per million output tokens.
• GPT-6.1 Sol costs $2 per million input tokens and $10 per million output tokens, about one-fifth of Astra’s prices.
• Its cached input costs $0.10 per million tokens, 95% less than standard input pricing.
• In July 2026, OpenAI cut Luna’s price by 80% and Terra’s by 20%.
• OpenAI’s APIs process more than 15 billion tokens per minute.

Output on GPT-6 Astra costs $50 per million tokens, against $1.20 for Luna. The spread lets developers route easy tasks to cheap models and keep the expensive tier for hard ones.

Stargate and OpenAI Compute Capacity

• OpenAI committed in January 2025 to securing 10 GW of US AI infrastructure by 2029 and says it has already surpassed that milestone.
• More than 3 GW was added in the 90 days before OpenAI’s April 29, 2026 update.
• By September 2025, Stargate had nearly 7 gigawatts of planned capacity and over $400 billion in investment over three years.
• OpenAI, Oracle and SoftBank reviewed over 300 proposals from more than 30 states.
• OpenAI secured 3 GW of dedicated inference capacity and 2 GW of training on NVIDIA Vera Rubin systems.
• OpenAI’s GPT-5.5 was trained at the flagship Stargate site in Abilene, Texas, which runs NVIDIA GB200 systems.

Source: OpenAI, 2025 and 2026

By the numbers: NVIDIA intends to invest up to $100 billion in OpenAI as each gigawatt is deployed. AMD agreed to 6 gigawatts of GPUs and Broadcom to 10 gigawatts of custom accelerators. The five new Stargate sites alone are expected to create over 25,000 onsite jobs.

Conclusion

ChatGPT reaches more than 1.2 billion people a week, and OpenAI’s latest round valued the company at $852 billion post-money. Microsoft’s audited filing shows the money behind the headlines, and Pew and Menlo show where OpenAI leads and where Anthropic has caught up.

The next numbers to watch are enterprise revenue reaching parity with consumer, the gigawatts Stargate brings online and whether Codex’s spread beyond engineering holds.
