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.

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.
