ChatGPT closed out its third year as the fastest-growing consumer application in history, reaching 800 million weekly active users — roughly one in ten adults on Earth. Below are the verified 2026 figures on ChatGPT’s users, revenue, downloads, enterprise adoption and traffic, each tied to a named primary source.
How many people use ChatGPT?
ChatGPT reached 800 million weekly active users in October 2025, when OpenAI CEO Sam Altman announced the milestone at the company’s DevDay event (TechCrunch, Oct 2025). That is double the 400 million weekly users OpenAI reported in February 2025 and up from roughly 700 million in July 2025. Engagement has scaled with the audience: by mid-2025 users were sending about 2.5 billion prompts every day — close to 29,000 per second (TechCrunch, Jul 2025). OpenAI’s own State of Enterprise AI report reiterated the 800 million figure, framing rapid consumer adoption as a flywheel that pulls AI into workplaces. The company has publicly targeted 1 billion weekly users, a threshold ChatGPT is approaching heading into 2026.
ChatGPT revenue and paid subscribers
OpenAI’s annualized revenue run-rate reached roughly $20 billion by the end of 2025 and climbed to about $25 billion in early 2026 (The Information, reported via Yahoo Finance, 2026). Because OpenAI passed $1 billion in annualized revenue in mid-2023, its run-rate has expanded close to 20-fold in under three years. The bulk of that revenue comes from ChatGPT subscriptions across four tiers — Plus ($20/mo), Team ($25/user/mo), Pro ($200/mo) and Enterprise (custom). Reported figures put paid ChatGPT subscribers north of 20 million (Business of Apps, 2026), with premium and business plans driving the fastest growth in average revenue per user.
App downloads and web traffic
ChatGPT was the second most downloaded app worldwide in 2025, trailing only TikTok, and in July 2025 it became the fastest app ever to cross 1 billion cumulative downloads across the App Store and Google Play (Sensor Tower, 2026). It logged about 470 million installs in the first half of 2025 alone — roughly 3.7x its nearest competitor — while total time spent in the app surged more than 400% year over year. On the web, chatgpt.com recorded 5.73 billion visits in March 2026, up 7.08% month over month, ranking as a top-ten global website and the #1 property in the AI chatbots category (Similarweb, Mar 2026).
Enterprise adoption
OpenAI surpassed 1 million business customers in November 2025, which it calls the fastest-growing business platform in history (OpenAI, Nov 2025). The company now serves more than 7 million ChatGPT workplace seats, with Enterprise seats up roughly 9x year over year (OpenAI, State of Enterprise AI, 2025). Weekly enterprise message volume has grown about 8x since November 2024, and API reasoning-token consumption per organization rose more than 300x year over year — a sign companies are deploying ChatGPT for heavier automated workloads, not just one-off queries. Adoption is heaviest in professional services, finance and technology.
Who uses ChatGPT: demographics
ChatGPT’s user base skews young and has moved toward gender parity. As of 2026 the audience is roughly 54% male and 46% female, a sharp shift from the tool’s early, heavily male adoption (Similarweb data). Adults aged 25-34 are the single largest cohort. In the United States, 58% of adults aged 18-29 have used ChatGPT, versus only about 10% of those 65 and older — a near 6x generational gap (Backlinko, citing Pew Research, 2026). Backlinko’s analysis also finds usage concentrated among students and knowledge workers, with writing, coding and research leading the use-case mix.
ChatGPT usage by country
The United States supplies the largest share of ChatGPT web traffic at about 18.5%, followed by India at roughly 9.8% (Similarweb, 2026). Together the two markets account for well over a quarter of global traffic. India is the fastest-growing major market: after the early-2026 launch of the lower-priced ChatGPT Go tier, OpenAI reported the country reached about 100 million weekly active users, underscoring how localized pricing is expanding access in emerging markets. Desktop still accounts for the majority of chatgpt.com sessions, though mobile’s share is rising quickly in high-growth markets such as India and Brazil.
