ChatGPT and OpenAI Statistics 2026: Users, Revenue, Market Share and Growth Data

Key ChatGPT Stats

• ChatGPT had more than 900 million weekly active users worldwide by December 2025, up from 300 million a year earlier.
• ChatGPT had an estimated 67.7 million monthly active users in the US based on eMarketer’s latest estimate.
• 34% of US adults said they had used ChatGPT as of June 2025, rising to 58% among adults ages 18 to 29.
• ChatGPT Plus had more than 10 million paying subscribers, while ChatGPT Enterprise, Team, and Edu together had more than 5 million paying users.
• ChatGPT accounted for 62.5% of B2C subscription sales among AI tools in June 2025.
• OpenAI’s monthly revenue reached $1 billion in October 2025, implying a $12 billion annualized run rate.
• OpenAI had raised $57.9 billion across nine funding rounds and was reported at a $500 billion valuation by late 2025.
• Average time spent per ChatGPT web session reached 12 minutes and 24 seconds in November 2024.

ChatGPT entered 2026 with a scale gap that still looks unusual even by consumer internet standards. The core product is no longer just a breakout chatbot. It is a mass-market consumer service, a growing enterprise software line, and the distribution layer for OpenAI’s broader product strategy.

The numbers also show why ChatGPT and OpenAI need to be read together. Some of the most important usage signals sit at the product layer, such as weekly active users and paid subscribers, while the clearest business signals sit at the company layer, including revenue, valuation, funding, and employee growth.

How Many People Use ChatGPT?

The latest figure in your source set puts ChatGPT at more than 900 million weekly active users worldwide in December 2025. That is a sharp acceleration from 100 million in November 2023, 200 million in August 2024, 300 million in December 2024, and 400 million in February 2025, before growth continued through 700 million in August 2025 and 800 million in October 2025. That trajectory matters because it shows ChatGPT adding hundreds of millions of weekly users in under a year, not simply defending an early lead.

One caution is that not every user metric in the available data measures the same thing. The 900 million figure is weekly active users worldwide, while the 67.7 million US figure is monthly active users, and the 34% adoption statistic measures Americans who say they have ever used ChatGPT. Those numbers are directionally consistent, but they are not interchangeable. Taken together, they show both enormous global reach and meaningful mainstream penetration in the US market.

ChatGPT User Growth Timeline

The user growth curve is one of the clearest signals in the dataset because it covers several major checkpoints rather than a single headline number. Growth did not flatten after the initial launch wave. Instead, ChatGPT kept compounding from a large existing base, which is harder to do than simply posting big early percentages from a small denominator.

That pattern also helps explain why OpenAI’s broader business metrics have moved so quickly. A product that reaches hundreds of millions of weekly users has a larger funnel for upgrades, enterprise conversions, API expansion, and adjacent product launches. In practical terms, distribution is now one of OpenAI’s strongest competitive assets.

ChatGPT Adoption in the United States

In the US, the strongest broad adoption number in the dataset is that 34% of adults said they had ever used ChatGPT as of June 2025, up from 18% in July 2023. That is a large move in a short period for a product category that barely existed at mainstream scale two years earlier. The age split is just as notable: 58% of adults ages 18 to 29 reported having used ChatGPT, compared with 41% for ages 30 to 49, 25% for ages 50 to 64, and 10% for adults 65 and older. [Pew Research Center]

eMarketer’s estimate of 67.7 million monthly active users in the US adds a different layer to the picture. Survey-based “ever used” data tells us ChatGPT has crossed into mainstream awareness, while MAU estimates suggest that awareness is converting into repeat usage at significant scale. Together, those figures point to a product that is no longer confined to students, developers, or early adopters. [eMarketer]

ChatGPT Use Frequency by Country

The Reuters Institute data in your source set is useful because it measures behavior instead of awareness. In that survey, 22% of respondents in the United States said they use ChatGPT at least once a month, made up of 7% daily, 11% weekly, and 4% monthly users. Denmark showed a comparable monthly reach through a different mix of frequent and occasional usage, while Japan posted the lowest reported use across the six-country sample. [Reuters Institute]

This is not a traffic table, and it does not measure every market in which ChatGPT is strong. Still, it offers a useful snapshot of how frequently people say they return to the product after first trying it. The US stands out not only for reach, but for a relatively high daily-use share, which matters more for monetization and habit formation than one-off trial.

Paid Subscribers and Enterprise Growth

ChatGPT’s consumer subscription business is now large enough to matter on its own. According to OpenAI COO Brad Lightcap, ChatGPT had more than 10 million paying subscribers, and The Information report linked in your source set says the figure had passed 11 million. Retention data from Earnest Analytics suggests this base is relatively sticky, with more than 89% of subscribers still paying after one quarter and 74% still paying after three quarters. That matters because retention is often the difference between a curiosity product and a durable subscription business. [The Information] [Earnest Analytics]

Enterprise traction is also moving fast. The available figures indicate more than 5 million paying users across ChatGPT Enterprise, Team, and Edu, up from 600,000 reported in April 2024 and 150,000 users from 260 organizations in January 2024. Even allowing for changes in how those categories are grouped, the direction is clear: OpenAI has moved from early pilot demand into a much larger seat-based enterprise business. [Bloomberg] [Reuters] [CNBC]

The paid mix is also expanding upward. ChatGPT Pro launched at $200 per month in December 2024, and Earnest Analytics estimated that Pro already represented 5.8% of OpenAI consumer sales by January 1, 2025. Sam Altman also said Pro was unprofitable because usage was so heavy, which is a reminder that strong demand does not always translate neatly into margin when inference costs are still high.

Engagement, Market Share, and Traffic Signals

Usage depth matters almost as much as reach, and the strongest engagement datapoint in the source set is Semrush’s estimate that the average ChatGPT web session lasted 12 minutes and 24 seconds in November 2024. For a utility product, that is a meaningful amount of attention. It suggests users are not only arriving; they are spending enough time in-session to complete substantial tasks. [Semrush]

On the commercial side, ChatGPT accounted for 62.5% of B2C subscription sales among AI tools in June 2025, according to Earnest Analytics, and 59.47% of monthly web traffic to the top 50 generative AI web products by December 2025 in the broader market snapshots cited in your raw data. Those are two different market-share lenses, but both point in the same direction: ChatGPT remained the category’s center of gravity even as rivals gained visibility.

OpenAI Revenue, Funding, Valuation, and Workforce

OpenAI’s business metrics now reflect the scale of ChatGPT’s distribution. The company reached $1 billion in monthly revenue in October 2025, equal to a $12 billion annualized revenue run rate, according to The Information. That is a useful benchmark because it ties user growth to actual monetization rather than attention alone. [The Information]

Capital formation has expanded alongside revenue. The raw source set lists $57.9 billion in total funding across nine rounds, and a valuation that rose from $86 billion in February 2024 to $500 billion by late 2025. OpenAI also had more than 3,700 employees worldwide and active roles across 14 office locations, which helps frame the organizational scale required to support its product, research, and infrastructure ambitions.

What the Data Tells Us

The main signal in this dataset is not simply that ChatGPT is big. It is that OpenAI has turned ChatGPT’s lead into a multi-layered business with consumer scale, enterprise penetration, subscription depth, and revenue momentum all reinforcing one another. The exact figures will keep moving, but the structure of the story is already visible: ChatGPT is no longer just an AI app with breakout adoption. It is the distribution engine behind one of the largest and fastest-scaling AI companies in the market.
