Generative AI is the fastest-adopted technology in modern history. ChatGPT passed roughly 900 million weekly active users in early 2026 (TechCrunch), 71% of organizations used generative AI in at least one function in 2024 (Stanford HAI), and OpenAI reached about $25 billion in annualized revenue (Sacra). This page gathers the most important generative AI statistics for 2026.
Executive summary
- Fast Fact: ChatGPT crossed 900 million weekly active users in February 2026 — doubling its base from 12 months earlier.
- Primary Driver: Falling inference costs (roughly 280× cheaper than late 2022) and improving model capability have made generative AI cheap enough to embed in everyday workflows.
- Top Enterprise Use Case: Coding/engineering, capturing ~55% of departmental application-layer spend per Menlo Ventures.
- Commercial Scale: OpenAI reached ~$25B annualized revenue in early 2026, with 1M+ business customers and 9M+ paying business seats.
Users and engagement
ChatGPT reached approximately 900 million weekly active users in February 2026, up from 400 million a year earlier (TechCrunch). Beyond consumers, OpenAI reported crossing 1 million business customers in late 2025, with more than 9 million paying business seats (Sacra).

Where enterprise generative-AI budgets go
Enterprises spent $37 billion on generative AI in 2025, with coding the dominant departmental use case at roughly 55% of application-layer spend (Menlo Ventures).
| Department | Share of departmental AI spend |
|---|---|
| Coding / engineering | ~55% ($4.0B) |
| IT | ~10% |
| Marketing | ~9% |
| Customer success | ~9% |
| Design | ~7% |
| HR | ~5% |
Deep dive: why coding dominates
Coding has clean, measurable productivity outcomes and the shortest time-to-value of any enterprise generative-AI workload. The category includes AI pair-programmers, agentic IDE assistants, code review, and automated migration tools — all running on top of an existing developer base, which makes per-seat ROI straightforward to justify.
Revenue and market
The commercial scale of generative AI is now significant. OpenAI reached roughly $25 billion in annualized revenue in early 2026 — about $2 billion per month, up from around $20 billion at the end of 2025 (Sacra). For the broader capital picture, see our Investment & Funding coverage.
