ChatGPT has 900 million weekly active users and handles ~2.5 billion prompts a day. The verified 2026 ChatGPT user statistics — plus Gemini, Perplexity and Copilot for context.
ChatGPT has 900 million weekly active users as of February 2026 and handles roughly 2.5 billion prompts per day globally, according to OpenAI. In the United States, 34% of adults say they have used ChatGPT — about double the share in 2023 — rising to 58% among adults under 30. By any measure, it is now one of the most-used software products on earth.
TL;DR: As of early 2026, ChatGPT has 900 million weekly active users, up from 800 million in October 2025, and processes ~2.5 billion prompts a day. 34% of US adults have used it, including 58% of under-30s. It’s part of a broader AI-search shift: Google AI Overviews reach 2B+ people monthly and the Gemini app has 750M+ monthly users.
ChatGPT reached 900 million weekly active users in February 2026, up from 800 million at OpenAI’s DevDay in October 2025 (OpenAI via TechCrunch). On volume, users send roughly 2.5 billion prompts every day, with about 330 million of those coming from the United States (OpenAI via Axios/TechCrunch).
For adoption among the general public, the cleanest primary source is Pew Research: 34% of US adults have used ChatGPT as of mid-2025 — about double the 2023 figure — climbing to 58% of adults under 30 (Pew Research).
| Metric | Figure | Source |
|---|---|---|
| Weekly active users | 900 million (Feb 2026) | OpenAI |
| Prior milestone | 800 million (Oct 2025) | OpenAI DevDay |
| Prompts per day | ~2.5 billion | OpenAI |
| US adults who’ve used it | 34% (58% of under-30s) | Pew Research |
ChatGPT is the biggest single AI assistant, but it isn’t the whole story. The shift to AI search spans several platforms:
A note on the numbers: “weekly active users” (ChatGPT), “monthly active users” (Gemini), “queries” (Perplexity) and “paid seats” (Copilot) are different metrics and aren’t directly comparable — but together they show AI assistants are now mainstream, not niche.
When a third of US adults — and most under-30s — use ChatGPT, a meaningful share are asking it the same questions they used to type into Google: which clinic, which product, which service. If your business isn’t part of the answer, you’re invisible to that demand. This is why so many businesses rank on Google but never appear in ChatGPT, and why how AI chooses which sources to cite is now a discipline of its own.
