How many people use ChatGPT in 2026
ChatGPT has more than 1 billion weekly active users, a figure OpenAI disclosed on 31 August 2026 in its ChatGPT Ads update. The base has grown every quarter since launch, and the table below traces the milestones as each was reported.
Weekly active users over time
| Date | Weekly active users | Source |
|---|---|---|
| December 2024 | 300 million | Reuters |
| February 2025 | 400 million | Reuters |
| End of March 2025 | 500 million | TechCrunch |
| August 2025 | Approaching 700 million | TechCrunch |
| October 2025 | 800 million | TechCrunch |
| February 2026 | 900 million | Search Engine Land |
| August 2026 | More than 1 billion | OpenAI |
Prompts and messages
- ChatGPT receives about 2.5 billion prompts a day, roughly 330 million of them from US users, OpenAI told Axios in July 2025, as reported by TechCrunch.
- That is up from more than 1 billion queries a day in December 2024, so daily volume more than doubled in about eight months, per the same TechCrunch report.
- OpenAI's API processes over 6 billion tokens a minute and 4 million developers have built on it, Sam Altman said at DevDay in October 2025.
Weekly active users is OpenAI's preferred metric and is not independently audited. The daily prompt count is the better proxy for how much answer-space exists for a brand to appear in.
Who uses ChatGPT
44% of US adults use ChatGPT, more than double the 18% who had tried it in 2023, and adoption is spreading fastest in lower-income countries. Pew measures the US by survey; OpenAI's own study describes the global consumer base.
US adoption by year and age
| Group | Share who use ChatGPT | Source |
|---|---|---|
| All US adults, 2023 | 18% | Pew |
| All US adults, 2025 | 34% | Pew |
| All US adults, 2026 | 44% | Pew |
| Ages 18 to 29 | 61% | Pew |
| Ages 30 to 49 | 55% | Pew |
| Ages 50 to 64 | 37% | Pew |
| Ages 65 and over | 19% | Pew |
Education, gender and geography
- About half of US adults with a bachelor's degree (51%) or a postgraduate degree (52%) have used ChatGPT, against 18% of those with a high school education or less, Pew found in its 2025 survey.
- Among users with classifiable first names, the share with typically feminine names rose from 37% in January 2024 to 52% by July 2025, per OpenAI's usage study.
- By May 2025, adoption growth rates in the lowest-income countries were over four times those in the highest-income countries, OpenAI reports.
- ChatGPT is used by 44% of US adults against 24% for Gemini, the next most-used chatbot, per Pew's February 2026 survey.
The age gradient is the number to remember. A buyer under 50 is roughly twice as likely to use ChatGPT as one over 50, which changes which prompts matter for a B2B category versus a retirement product.
What people use ChatGPT for
Three-quarters of ChatGPT conversations are about practical guidance, seeking information and writing, and about 30% of consumer usage is work-related. OpenAI's study of 1.5 million conversations is the source, with Pew adding the US work figures.
- Roughly 30% of consumer usage is work-related and 70% is not, with both categories still growing, per OpenAI.
- Writing is the most common work task, while coding and self-expression remain niche, the same study found.
- 49% of messages are "asking" for advice or information, 40% are "doing" tasks such as drafting or planning, and 11% are "expressing", OpenAI reports.
- 28% of employed US adults use ChatGPT for work, up 20 percentage points in two years, per Pew.
- 26% of US adults have used ChatGPT to learn something and 22% for entertainment, up from 8% and 11% in March 2023, Pew found.
The "asking" half is the part that matters for a brand. Those are the messages where a person wants a recommendation, a comparison or a shortlist, and getting cited by ChatGPT means being the page the model quotes when it answers one.
ChatGPT search statistics
Web search is available on every ChatGPT plan, including to people who are not signed in, per OpenAI's help centre. ChatGPT decides on its own when a question needs it, and what the search does with your page is documented in more detail than most people realise.
How search retrieves pages
- ChatGPT rewrites a question into one or more targeted queries and sends them to third-party search providers, then may send more specific follow-up queries after reviewing the first results, OpenAI states.
- A site becomes eligible for inclusion by allowing OAI-SearchBot to crawl it and confirming that its host or CDN accepts traffic from OpenAI's published IP ranges; placement is not guaranteed, per the same document.
- The original search model was a fine-tuned version of GPT-4o, and search was opened to everyone in supported regions on 5 February 2025, per OpenAI's launch post.
How often ChatGPT cites and sends traffic
- Citation presence in US ChatGPT prompts rose from about 1.6% in June 2025 to roughly 6.8% by May 2026, Similarweb found.
- Travel and hospitality prompts carry a citation about 23% of the time, automotive about 20%, and professional services under 4%, per Similarweb.
- After ChatGPT replaced footnote citations with clickable brand names in May 2026, homepage referrals rose from roughly 26 to 29% of its referral traffic to about 62 to 63%, and stayed there, Similarweb reports.
- ChatGPT's share of worldwide generative AI web traffic fell from about 76% in June 2025 to roughly 53% by May 2026, while its absolute visits stayed flat, according to Similarweb.
Two of those numbers pull in opposite directions. A sub-7% citation rate means most answers name no source at all, while the homepage-referral shift means that when a brand is named, the click goes to the front door rather than a deep page. Optimising for ChatGPT search has to plan for both.
ChatGPT Ads statistics
ChatGPT Ads reached a $1 billion annualised revenue run rate in under 200 days and is used by tens of thousands of advertisers, OpenAI said on 31 August 2026. Ads are shown only to Free and Go users, so the audience is a subset of the billion.
Who sees ads and what they cost
- Ads are not shown to users on Plus, Pro or any Business plan, or to accounts identified as under 18, per OpenAI's ad basics.
- OpenAI recommends a starting maximum bid of $3 to $5 per click for CPC campaigns and runs a relevance-weighted second-price auction, the same page states.
- Self-serve Ads Manager launched in May 2026 and opened the platform to SMBs, which now represent a material share of the business, OpenAI reports.
Scale and results
- CPC and outcome-optimised bidding account for the majority of campaigns, and the ecosystem includes more than 50 technology and measurement partners across over 40 countries, per OpenAI.
- OpenAI cites an ecommerce advertiser achieving 3x return on ad spend over 28 days and a partner reporting that more than 80% of ad-driven ChatGPT traffic came from new customers, in the same update.
- Roughly 26% of ChatGPT responses now contain an ad, about a third of ad impressions land in the first response of a session, and around a fifth appear ten or more messages in, per Similarweb.
OpenAI states that advertising does not influence the answers ChatGPT gives, so the paid unit and the earned citation are separate systems that happen to share a screen. Tracking brand mentions in ChatGPT is how you find out which of the two is doing the work.
ChatGPT revenue and paid plan statistics
OpenAI's annualised revenue passed $20 billion in 2025, up from $6 billion in 2024, its CFO said in a post reported by Reuters in January 2026. Advertising is now one of four revenue pillars alongside consumer subscriptions, enterprise plans and the API.
- Paying business users passed 2 million in February 2025, more than double the previous September, Reuters reported.
- ChatGPT has around 50 million paying subscribers and more than 5 million paying users across Enterprise, Team and Edu plans, per Search Engine Land's statistics guide, updated 9 September 2026.
- The ChatGPT Plus plan costs $20 a month and Pro costs $200 a month, per the same guide.
- OpenAI describes an advertising-supported free tier, consumer subscriptions, enterprise offerings and usage-based APIs as its four business lines, in its August 2026 update.
The subscriber figures matter for one reason: paid users never see ads. A brand that sells to enterprise buyers on company seats can only reach them through the answer itself.
What ChatGPT statistics mean for a brand
ChatGPT is a billion-user surface where most answers cite nothing. A brand appears either because the model already knows it or because a page was fetched at answer time, and neither route depends on ad spend.
Where the answer comes from
OpenAI's models are built from three information sources: publicly available internet content, data accessed through partnerships, and information provided by users, trainers and researchers, per its model development page. Live search adds a fourth path at answer time. Entity signals a model learns come from the first; citations come from the fourth.
What to measure
Measure whether your brand is named and linked on the prompts your buyers actually type, on a fixed schedule. The citation rate itself moved four times in eleven months, so a single reading is not evidence. That is the core of answer engine optimization, and the statistics on this page are the denominator it works against.
