Newest ChatGPT Usage Statistics: September 2026

ChatGPT has moved well beyond being a new AI tool people try out of curiosity. By 2026, it has become part of how people search for information, write, study, work, shop, and solve everyday problems.

The numbers behind that growth are striking. OpenAI’s own figures put weekly active users at 900 million, while independent tracking puts standalone ChatGPT usage at 853 million weekly users. Combined with Microsoft Copilot, the figure rises to about 904 million weekly users.

But user numbers are only one part of the story. ChatGPT’s audience is changing, its competitors are gaining ground, businesses are adopting it at scale, and its influence now extends into education, search, purchasing decisions, and workplace productivity.

Here is a closer look at the most important ChatGPT statistics for 2026.

ChatGPT Usage Statistics at a Glance

Metric	2026 figure
Standalone ChatGPT weekly users	853 million

How Many People Use ChatGPT?

ChatGPT reached 900 million weekly active users by February 27, 2026, according to OpenAI. First Page Sage’s September 2026 estimate puts standalone ChatGPT at 853 million weekly users and ChatGPT plus Microsoft Copilot at 904 million.

The scale becomes even clearer when looking at activity. ChatGPT and Copilot together generate an estimated 6.4 billion visits every week.

ChatGPT’s growth has been unusually fast:

Date	Milestone
November 30, 2022	Public launch
December 5, 2022	1 million users
January 2023	100 million monthly active users
December 2024	300 million weekly users
February 2025	400 million weekly users
September 2025	700 million weekly users
October 2025	800 million weekly users
February 2026	900 million weekly users
May–June 2026	1 billion monthly active users

Users now send approximately 2.5 billion prompts every day. Around 330 million of those prompts come from the United States.

ChatGPT.com also recorded 5.723 billion visits in January 2026 and 5.51 billion visits in April 2026.

ChatGPT Market Share vs. Competitors

ChatGPT remains the leading AI chatbot, although its share of the overall market has declined as competing services have expanded.

ChatGPT’s generative AI chatbot market share is approximately 86.7% in January 2025, compared with roughly 60%–65% during early to mid-2026 depending on the measurement method.

Google Gemini has been one of the strongest challengers. Its app reached approximately 950 million monthly users by May 2026, compared with 400 million a year earlier.

Microsoft Copilot had an estimated 103 million users in February 2026.

The important point is that falling market share does not necessarily mean ChatGPT is losing users. The entire AI chatbot market is growing rapidly, allowing competitors to gain share while ChatGPT continues adding users.

ChatGPT Revenue, Valuation and Funding

OpenAI’s financial growth has been almost as dramatic as its user growth.

The company recorded approximately $13.1 billion in booked revenue during 2025. Its annualized revenue run rate reached about $40 billion by August 2026.

At the same time, the company continues to spend heavily on infrastructure and development.

Other financial figures include:

• OpenAI crossed $1 billion in monthly revenue in October 2025.
• Enterprise revenue exceeded 40% of total revenue.
• ChatGPT Pro generated more than $1.2 billion in annual recurring revenue.
• OpenAI raised approximately $122 billion in a funding round that closed in March 2026.
• Its reported post-money valuation reached $852 billion.
• Total funding was estimated at approximately $138.4 billion across six rounds.

How Many People Pay for ChatGPT?

OpenAI reported 50 million paying subscribers across its consumer and business offerings in April 2026.

That figure includes more than just ChatGPT Plus. The available plans include Free, Go, Plus, Pro, Business/Team, and Enterprise.

Plan	Listed price
Free	$0
Go	$8/month
Plus	$20/month
Pro	$100/month
Pro Extended	$200/month
Business/Team	$20–$25 per seat/month
Enterprise	Custom

Retention also tends to improve as customers move toward higher-value plans. Enterprise accounts reportedly retained 88% of subscribers after one year, compared with 59% for individual Plus subscribers.

Separate credit-card panel data found that 89% of ChatGPT subscribers remained paying customers after one quarter, while 74% were still paying after three quarters.

Who Uses ChatGPT?

ChatGPT’s audience has changed considerably since its launch.

54.85% of ChatGPT users are between 18 and 34 years old. Similarweb data from February 2026 puts the website visitor split at approximately 53% male and 47% female.

OpenAI’s message-level research shows an even more noticeable change. The share of messages associated with female names increased from 37% in January 2024 to 52% by July 2025.

Age is another major factor. Pew Research found that 58% of US adults aged 18–29 had used ChatGPT, compared with 44% of US adults overall. Only 10% of US adults aged 65 and older had tried ChatGPT.

Among US adults, chatbot usage in February 2026 was:

AI chatbot	Share of US adults
ChatGPT	44%
Google Gemini	24%
Microsoft Copilot	17%
Meta AI	14%
Grok	8%
Claude	6%
Character.ai	3%

Overall, 49% of US adults reported using an AI chatbot, up from 33% in 2024 and 23% in 2023.

ChatGPT Usage by Country

The United States and India are the two largest sources of ChatGPT traffic.

According to the September 2026 figures, the US accounts for 17.1% of visits and India accounts for 16.5%.

Country	Share of visits
United States	17.1%
India	16.5%
Brazil	5.8%
Canada	5.4%
France	4.3%
Spain	3.7%
Mexico	3.6%
United Kingdom	2.7%
Italy	2.5%
Philippines	2.5%
Germany	2.4%
Australia	1.8%
Colombia	1.6%
Argentina	1.3%
Netherlands	1.1%
South Korea	1.1%

India passed 100 million weekly active users in early 2026 and grew 41% year over year.

It also puts ChatGPT’s monthly app users in India at approximately 180 million, ahead of Gemini at 118 million, Perplexity at 19 million, and Meta AI at 12 million.

ChatGPT is available in more than 160 countries and supports around 95 languages. More than half of active users now have a primary language other than English.

What Do People Use ChatGPT For?

One of the most useful ChatGPT statistics is not its user count but what those users actually do with it.

OpenAI and the National Bureau of Economic Research analyzed 1.5 million messages from May 2024 through July 2025.

The research divided interactions into three broad categories:

• Asking: 49%
• Doing: 40%
• Expressing: 11%

Asking includes requests for information, solutions, advice, and second opinions. Doing includes activities such as drafting, planning, and programming. Expressing includes personal reflection, exploration, and play.

Nearly 80% of conversations fall into three broad areas: practical guidance, information seeking, and writing assistance.

July 2026 use-case breakdown shows:

Use case	Share
General research	36.3%
Academic research	19.4%
Email composition	14.4%
Coding assistance	13.5%
Commercial research	5.8%
Marketing copywriting	3.1%
Other	7.5%

Non-work usage has also grown considerably, increasing from 53% of messages in June 2024 to 73% in June 2025.

Yes — the previous version mixed percentages, comparisons, and descriptions in a way that made the tables hard to understand. The numbers should clearly state what was measured and what the percentage means.

Here is a cleaner version using only the new data from this source, without repeating the main statistics from your earlier article.

ChatGPT Use Among U.S. Workers

Worker Group	Share Using ChatGPT for Work
U.S. workers overall	More than 25%
U.S. workers with postgraduate degrees	45%

This shows that ChatGPT has moved beyond personal use and into regular workplace activity. OpenAI reported that more than one in four U.S. workers use ChatGPT for work, while adoption is even higher among workers with postgraduate degrees.

How Employees Use ChatGPT Across Departments

Department	Most Common Uses
Engineering	Programming, debugging, unit tests
IT	Research, troubleshooting, finding information
Analytics	Data analysis, research, interpreting datasets
Marketing	Writing, research, media generation
Sales	Writing, research, media generation
Design	Media generation, coding
Project Management	Writing, media generation, coding, data analysis

The data shows that employees use ChatGPT differently depending on their job. Programming is especially common in engineering and IT, while marketing and sales rely more heavily on writing, research, and media generation.

ChatGPT’s Effect on Technical Skills

Finding from BCG Study	Improvement
Technical task 1	49 percentage points higher
Technical task 2	20 percentage points higher
Technical task 3	18 percentage points higher

These figures come from a Boston University and BCG study cited in the OpenAI report. The study compared consultants who received ChatGPT training with a control group. The ChatGPT group scored 49, 20, and 18 percentage points higher on three technical tasks.

ChatGPT and Workplace Productivity

ChatGPT in Business and Enterprise

ChatGPT has become a significant workplace tool rather than something used mainly by individual consumers.

92% of Fortune 500 companies are active ChatGPT customers. There are more than 7 million active enterprise and workplace seats, along with more than 9 million paying business users.

More than 1 million organizations reportedly have a paid ChatGPT business account.

US business adoption of paid AI services reached 50.4% in March 2026. OpenAI was the leading vendor, with 35.2% of US businesses using its services.

However, adoption does not automatically translate into effortless productivity. A survey of more than 1,100 enterprise AI users found that 58% spend at least three hours each week revising or redoing AI-generated output.

ChatGPT and Education

Students are among the most active users of generative AI.

84% of US high school students had used generative AI for schoolwork by May 2025. ChatGPT specifically had been used by 69% for assignments and homework.

Among UK undergraduates, 95% reportedly use AI tools, with 94% using them for assessed work.

Other education figures include:

Finding	Figure
US teens who have used ChatGPT	59%
US teens using AI chatbots for schoolwork	54%
Teens using AI for most/all schoolwork	10%
University students globally using ChatGPT academically	66%
Students using AI for homework help	62%
UK students putting AI-generated text directly into assessed work	12%
College professors aware of ChatGPT	82%
Professors concerned about AI-enabled cheating	72%

Students are not using ChatGPT for just one type of task. Common uses include understanding assignments, brainstorming ideas, finding facts, and drafting or revising writing.

ChatGPT Mobile App Statistics

Mobile usage has become another major part of ChatGPT’s growth.

ChatGPT crossed 1 billion global monthly active app users in May–June 2026.

During 2025:

• App downloads increased 148%.
• In-app purchase revenue increased 254%.
• Total time spent inside the app increased 426%.

ChatGPT ranked second worldwide among apps by downloads and was the third-highest-grossing app of 2025.

Mobile revenue reached approximately $1.35 billion in fiscal 2025, representing 673% year-over-year growth.

The broader generative AI app market grew rapidly as well. Downloads reached 3.8 billion in 2025, while in-app purchase revenue exceeded $5 billion.

Is ChatGPT Replacing Google?

ChatGPT is changing search behavior, but the available figures do not support the idea that people have simply stopped using Google.

Similarweb found that 95% of ChatGPT users also use Google. That figure remained unchanged between September 2025 and May 2026.

At the same time, 37% of consumers reportedly now begin some searches with an AI tool rather than a traditional search engine.

Google still sends vastly more referral traffic to websites. Ahrefs estimated that Google sends roughly 190 times more referral traffic than ChatGPT.

Interestingly, visitors arriving through ChatGPT can be more engaged. AI-referred visitors spend around 15 minutes on a website, compared with approximately eight minutes for Google visitors.

This suggests that AI search and traditional search are currently operating alongside each other rather than one completely replacing the other.

ChatGPT, Jobs and Productivity

The employment story around ChatGPT is more complicated than early predictions suggested.

A Danish study covering 25,000 workers across 7,000 workplaces found high AI adoption among companies that provided both AI tools and training. Yet the study found no measurable effect on wages or hours two years after adoption.

At the task level, however, productivity gains are easier to identify.

Research by Noy and Zhang found a 37% reduction in time spent on writing tasks. Another study involving customer-support workers measured a 15% productivity gain from a GPT-based assistant.

The data therefore points toward a distinction between saving time on individual tasks and creating measurable changes across the entire labor market.

How Much Energy and Water Does ChatGPT Use?

The environmental cost of AI is difficult to reduce to one number because different studies measure different things.

OpenAI’s reported average electricity use is 0.34 watt-hours per query. Its reported direct water use is 0.000085 gallons per query.

Independent estimates can be considerably higher for longer or more demanding AI workloads. One estimate puts GPT-5 reasoning-mode energy consumption at 18–45 watt-hours per prompt.

Another academic estimate calculated approximately 519 milliliters of water for a 100-word GPT-4 response using a broader methodology that includes water associated with electricity generation.

The difference between these numbers is largely about methodology. A short standard query and a long reasoning-heavy request do not consume the same amount of computing resources, and direct data-center cooling water is different from the broader water footprint associated with electricity generation.

ChatGPT’s Influence on Buying Decisions

ChatGPT is also becoming part of the customer journey.

The September 2026 figures show that travel and hospitality has the highest share of customers using ChatGPT somewhere during the purchasing process.

Industry	Customers using ChatGPT	Estimated financial impact
Travel & Hospitality	47%	$1.48 trillion
Retail & CPG	36%	$1.11 trillion
IT Services	34%	$936 billion
Lifestyle, Health & Wellness	32%	$891 billion
Food & Beverage	32%	$546 billion
Home Services	31%	$385 billion
Healthcare	29%	$378 billion
Automotive	29%	$243 billion
B2B SaaS	28%	$229 billion
Advertising & Marketing	27%	$156 billion
Fintech	25%	$135 billion
Insurance	23%	$104 billion
Real Estate	21%	$66 billion
Financial Services	21%	$21.7 billion
Education	19%	$12.6 billion

What Do These ChatGPT Statistics Tell Us?

The numbers paint a more interesting picture than a simple story of rapid user growth.

ChatGPT is still growing. Its user base continues to expand, although growth is no longer as explosive as it was during its first two years.

Its audience is becoming broader. The gender balance has moved considerably closer to parity, while usage has spread beyond younger technology-focused users.

Competition is increasing. Gemini, Claude, Copilot, and other services are capturing a larger portion of the expanding AI market. ChatGPT can therefore gain users while simultaneously losing market share.

Revenue is growing faster than many traditional software businesses ever manage. But OpenAI’s large losses show that enormous usage does not automatically translate into profitability.

Businesses are adopting AI at scale. Millions of workplace users and more than a million paying business organizations indicate that ChatGPT is no longer limited to individual experimentation.

Education is already deeply affected. Students are using AI for research, explanations, brainstorming, writing, and homework, while schools and universities continue working out where assistance ends and academic misconduct begins.

AI is changing search without eliminating traditional search. A large majority of ChatGPT users still use Google, suggesting that people are adding AI to their information habits rather than completely abandoning existing search engines.

Productivity gains are real, but broader labor-market effects remain less clear. Studies show meaningful time savings on specific tasks, while large-scale research has yet to show comparable economy-wide effects on wages or employment.

Final Thoughts

ChatGPT’s biggest statistic may not be any single number.

The more important change is how many different roles the product now occupies. The same service can be used as a research assistant in the morning, a writing tool in the afternoon, a coding assistant at work, and a study partner at night.

Its reach now extends across hundreds of millions of people, businesses, schools, mobile devices, search behavior, and purchasing decisions.

At the same time, the 2026 data shows that ChatGPT is entering a different phase. The question is no longer whether people will use AI. They already do.

The more important questions are how deeply AI becomes embedded in everyday work, whether competitors can narrow ChatGPT’s lead, how much value businesses actually get from adoption, and whether the productivity gains seen in individual tasks eventually translate into larger changes across the economy.

Data in this article is based on the supplied September 2026 source, which compiles figures from OpenAI, Pew Research Center, First Page Sage, Sensor Tower, Similarweb, Reuters, RAND, HEPI/Kortext, the Digital Education Council, and other named sources.
