ChatGPT Users Statistics and Facts (2026)

Introduction

ChatGPT has grown from a small AI demo into a mainstream tool in a short time. Reported figures show weekly active users climbed to 400 million in February 2025, then reached roughly 700 million by mid-September 2025; OpenAI CEO Sam Altman later said ChatGPT hit 800 million weekly active users in October 2025. Web traffic data points in the same direction: estimates based on Similarweb put chatgpt.com at about 5.8 to 5.9 billion visits in September 2025, up around 7.6% vs August. Because “users” and “visits” measure different things, they should be read together, not mixed.

In the sections that follow, we pull the most cited indicators of adoption: user growth, traffic trends, revenue (in USD), app downloads, market share, and country-level use, to show where ChatGPT stands and how fast it is expanding.

ChatGPT Weekly Users

• According to TechCrunch, ChatGPT reached about 800 million weekly active users as of Oct 6, 2025.
• Reuters states that OpenAI said ChatGPT passed 400 million weekly active users in Feb 2025.
• Based on these two updates, weekly users roughly doubled from 400 million to 800 million in about 8 months, not “in just weeks.”
• ChatGPT crossed 300 million weekly active users in Dec 2024.
• From Dec 2024 (300 Million) to Feb 2025 (400 Million), weekly users rose by about 33%.

• Reuters reports that OpenAI said ChatGPT reached 200 million weekly active users in Aug 2024.
• OpenAI (via an NBER-linked research post), ChatGPT had 700 million weekly active users by Sept 2025.

Weekly Active Users Over Time

• The eMarketer reported by Backlinko says ChatGPT has an estimated 67.7 million monthly active users in the US.

ChatGPT Monthly Reach

• Similarweb estimates that ChatGPT recorded about 5.904 billion monthly visits in Sep 2025.
• Some reports describe this as “MAU,” but visits are traffic, not unique users, because one person can create many visits in a month.
•  Visits were about 5.39 billion in Aug 2025 and about 5.8 billion in Sep 2025, representing a +7.606% month-over-month increase.
• According to TechCrunch, ChatGPT reached 800 million weekly active users in Oct 2025.
• Since OpenAI does not publish an official monthly active users figure, any MAU figure is an estimate and will depend on how many users return across multiple weeks.

ChatGPT Daily Usage and Query Volume

• A Similarweb study found that ChatGPT had about 5.904 billion visits in September 2025 (traffic, not unique users).
• Based on that monthly traffic, the average daily activity level is roughly 196.8 million visits, assuming a 30-day month.
• That same estimate equals about 8.2 million visits per hour, 136,667 visits per minute, and 2,278 visits per second (these are simple averages, not official real-time counts).
• TechCrunch reports that OpenAI told Axios that ChatGPT users send about 2.5 billion prompts per day worldwide (about 330 million from the US).
• Because visits ≠ users, you cannot treat “daily visits” as “daily active users,” since one person can generate many visits in a day.
• If you spread 800 million weekly active users evenly across 7 days, you get a rough DAU estimate of about 114.3 million users per day, but this is only a quick estimate and not an official number.
• According to Reuters, Similarweb data showed ~13 million unique visitors per day in January 2023, demonstrating how quickly usage scaled over time.
• OpenAI launched ChatGPT Pro on Dec 5, 2024, at USD 200 per month, aimed at users who need higher limits and stronger models.
• Some websites claim ChatGPT reached 10+ million daily queries within a week of launch, but OpenAI has not published a clear, official daily “queries in week 1” figure, so it should be treated as an estimate rather than a confirmed stat.

OpenAI and ChatGPT Revenue Statistics

• First reported by CNBC, OpenAI said its annualised revenue run rate reached about USD 10 billion in June 2025, including consumer products, ChatGPT business products, and the API (excluding Microsoft licensing revenue and large one-time deals).
• OpenAI, the company, announced USD 40 billion in new funding at a USD 300 billion post-money valuation in March 2025.
• Using the USD 300 billion valuation and the USD 10 billion annualised revenue figure, the valuation works out to roughly 30x annualised revenue (this is an estimate, as both numbers can be defined differently across reports).
• Reuters, summarising a Bloomberg report, mentioned that OpenAI expected revenue to grow to USD 12.7 billion in 2025 and to exceed USD 125 billion by 2029.
• Bloomberg report also states that OpenAI generated about USD 3.7 billion in 2024 revenue (reported via sources familiar with the matter).
• OpenAI’s CFO later said OpenAI’s annualised revenue was USD 6 billion in 2024 and exceeded USD 20 billion in 2025, which is a different metric than “annual revenue,” according to Reuters
• TechCrunch Reports (citing Appfigures estimates) that consumers spent about USD 487 Million on the ChatGPT mobile app in 2024 and about USD 2.48 Billion in 2025, representing roughly +408% YoY growth.
• ChatGPT’s mobile app crossed USD 3 billion in cumulative consumer spending by late 2025 (combined across App Store and Google Play).
• DemandSage (a third-party tracker), estimated monthly in-app revenue rose steadily for 12 straight months from Mar 2024 to Mar 2025, reaching about USD 108.0 million in Mar 2025, with +43.6% growth from Feb 2025 to Mar 2025.

ChatGPT User Gender Split

• About 54.66% of ChatGPT visitors are male and 45.34% are female, suggesting a fairly even split.

• This data is based on website traffic patterns, so it reflects visitor share, not confirmed “registered users” by gender.
• The small gap (under 10 percentage points) suggests that ChatGPT appeals to a wide audience and is used for common needs such as work tasks, learning, and everyday questions.
• Results can vary by method: according to OpenAI’s research, the share of users with names classified as typically feminine rose to 52% by July 2025 in their dataset, showing the gender gap has narrowed over time.
• Overall, the most reliable takeaway is that ChatGPT usage appears broad and roughly balanced, but exact shares depend on whether the source measures traffic or user-level activity.

ChatGPT Age Profile

• Similarweb estimates that most ChatGPT traffic comes from adults aged 18–34, who make up 52.99% of visitors.
• According to the same source, people aged 35–54 account for 32.91%, indicating strong use among working professionals, not just students or young adults.
• Users aged 55+ make up 14.11%, indicating that usage declines with age.
• The 65+ group is 5.23%, which suggests lower adoption among older audiences.
• Similarweb also notes that the 25–34 age group is the largest on chatgpt.com, which aligns with this breakdown.
• These figures reflect website audience/traffic, not official “registered users,” and the mix can change over time.

Top Countries Driving ChatGPT Traffic

• According to Similarweb, the US is the largest single source of ChatGPT website traffic, accounting for 17.2% of total visits.
• India is next with 8.27%, showing strong demand from a large, digital-first audience.
• Similarly, Brazil contributes 5.73%, and Japan contributes 3.7% of total visits.
• Germany accounts for 3.39% of visits and is the leading European country on this top-5 list.
• And all other countries combined account for 61.71%, which shows ChatGPT has a broad global footprint beyond the top markets.
• The reported month-to-month traffic-share change was US (+1.78%), India (+0.68%), Brazil (-0.96%), Japan (-1.83%), and Germany (-4.07%).

• These figures describe traffic share (visits), not unique users, so they should not be read as exact country-level user counts. 

Monthly ChatGPT Visitors Statistics

• Based on Similarweb estimates, ChatGPT recorded about 6.16 billion website visits in October 2025.
• The Similarweb-style estimates show that September 2025 traffic is often reported as ~5.8-5.9 billion visits (some charts round it to 5.8 billion), so the month-over-month rise into October is roughly 4%–6%, depending on rounding.
• The US accounts for the largest share of ChatGPT traffic, at about 17.45%, followed by India at about 7.99%.
• These country figures represent the share of visits, not the number of unique users in each country.
• Most access happens on desktop (71.74%), while mobile accounts for 28.26% of visits.
• Other high-traffic AI destinations, such as OpenAI.com, Claude, Perplexity, and Grok, which shows the category is competitive

• 21% of US workers say they use AI for at least some of their work, often including writing tasks such as drafts, summaries, and emails.
• OpenAI’s economic research writing is one of the most common work-related uses of ChatGPT, which supports the idea that many users rely on it for drafting and editing text.
• Many users also run ChatGPT drafts through separate grammar and clarity tools (such as Grammarly) to polish wording and fix errors, especially for professional writing.

ChatGPT Usage Growth Speed

• The average ChatGPT session lasts about 7 minutes and 4 seconds, suggesting many users stay long enough to read, ask follow-up questions, or refine their answers.
• ChatGPT reached 100 million users in about 2 months, according to widely cited industry estimates, making it one of the fastest-growing consumer apps at the time.
• In comparison, Facebook took about 4.5 years to reach 100 million users, showing how much faster ChatGPT scaled.
• Instagram Threads later reached 100 million users in about 2 days, faster than ChatGPT, but it is a different product type.

ChatGPT Market Share

• ChatGPT held 81.13% of the generative AI “AI search” market share in Oct 2025 (the same page shows an older 81.39% value crossed out, so 81.13% is the corrected figure).
• In the DemandSage table, ChatGPT’s share remained roughly at ~80% through Mar–Oct 2025, with a high of 84.21% (Apr 2025) and a low of 79.79% (May 2025).
• Worldwide AI Chatbot Market Share, ChatGPT’s share was 79.79% in Dec 2025, followed by Perplexity (10.85%), Google Gemini (4.68%), Microsoft Copilot (3.58%), and Claude (1.07%).
• These market-share numbers can differ by source because each tracker may use a different method (for example, “AI chatbot traffic share” vs “AI search share”).

ChatGPT App Downloads

• TechCrunch, citing Appfigures, says ChatGPT reached about 46 million downloads in Mar 2025, up 28% from Feb 2025.
• ChatGPT was downloaded about 43.1Million times in Oct 2025 across the App Store and Google Play.
• According to Business Insider (citing Appfigures), ChatGPT logged about 410.8M downloads in 2025 (year-to-date).
• I removed the 64.27M monthly downloads claim because I could not confirm that exact figure in a primary source like Appfigures in the checks above.

ChatGPT Key Predictions

• Deep Research in ChatGPT is designed to conduct multi-step online research and write a structured report, signalling a shift toward more agent-like work (not just quick answers).
• The Computer-Using Agent approach shows that AI can perform tasks using a standard computer screen with clicks and typing, which supports more hands-on automation.
• OpenAI’s Help Centre, “Connectors” have been renamed to Apps, and ChatGPT can connect with tools like Google Drive, SharePoint, GitHub, and HubSpot to pull context from your work.
• From a research view, these features suggest ChatGPT is likely to become more of a personal work assistant in 2026, handling longer workflows across your tools (for example, planning, drafting, and task follow-through). This is a directional estimate based on product rollout, not a confirmed roadmap.
• Special “expert modes” (such as for law, healthcare, or finance) are plausible, but these areas usually require stronger accuracy controls, privacy, and compliance, so rollout speed may vary by country and use case.
• According to Reuters, OpenAI is expected to produce its first custom AI chip in 2026 (reported via the Financial Times), which would help it run models more cheaply and rely less on outside chip supply.
• The same study shows OpenAI also continues to lock in large amounts of compute capacity (for example, a deal with Cerebras reported at over USD 10B), which supports higher usage and more advanced features.
• The Verge reports that OpenAI’s stated direction for 2026 is “practical adoption,” with more focus on real-world use in areas like health, science, and enterprise.

Conclusion

ChatGPT Users Statistics: ChatGPT’s growth remains rapid, with usage measured across weekly active users, web visits, prompts, revenue, downloads, and market share. The data also shows broad adoption across age groups, near-balanced gender reach, and strong demand in the US and India. At the same time, many figures are estimates based on traffic and third-party tracking, so “visits” should not be read as “users.”
