ChatGPT still reaches 1.2 billion people every week. OpenAI repeated the figure in early November, with consumer product lead Adam Fry saying weekly users had grown from 1 billion to 1.2 billion in two months, and CFO Sarah Friar adding that 300 million people now use ChatGPT for health and wellness and 200 million for personal finance.
The bigger shift is on the business side. Enterprise now makes up more than half of OpenAI’s revenue, President Greg Brockman says the company should be ready to go public in 2027, and OpenAI is reportedly raising around $20 billion at a valuation of about $1.25 trillion – scaled back from its first target after a sharp sell-off in AI stocks in early November.
On the web, ChatGPT’s share of AI traffic has now risen for four months in a row. Here are the most recent ChatGPT stats as of November 2026.

ChatGPT User Stats
1.2 billion weekly users (November 2026). OpenAI first cited the figure at DevDay on September 29, 2026, and consumer product lead Adam Fry repeated it on November 2, saying weekly users had grown from 1 billion to 1.2 billion in two months (via Sacra). That’s up from 900 million in February 2026.
Takeaway: ChatGPT added 300 million weekly users in seven months – roughly the population of the US.
300 million people use ChatGPT for health and wellness, and 200 million for personal finance, CFO Sarah Friar told CNBC on November 6, 2026 (via FourWeekMBA).
Takeaway: a quarter of ChatGPT’s weekly users now turn to it for health questions – a sign it’s becoming an everyday utility, not just a work tool.
| Date | ChatGPT Weekly Users |
| November 2026 | 1.2 billion (reconfirmed) |
| September 2026 | 1.2 billion |
| February 2026 | 900 million |
| October 2025 | 800 million |
| July 2025 | 700 million |

Takeaway: weekly users have tripled in 19 months – there’s no sign of a growth ceiling yet.
ChatGPT became the fastest app ever to reach 1 billion monthly users (June 2026, Sensor Tower).
Takeaway: it beat TikTok, Instagram and every other consumer app to the milestone.
~50 million paying subscribers across Plus, Pro, Business and Enterprise (OpenAI, early 2026).
Takeaway: only around 4% of weekly users pay – which is exactly why OpenAI has moved into advertising.
2 million+ business customers.
Takeaway: business adoption is accelerating, with OpenAI’s business customer count up 32% month on month in July alone.
20 million weekly users of OpenAI’s AI coding and work products (Codex, ChatGPT Work and related tools), per slides shown at an August 19 all-hands.
Takeaway: agents and coding tools are now a mass-market product, not a developer niche.
ChatGPT Market Share Stats
The market-share picture depends heavily on which data source you use – and in the latest numbers, ChatGPT is holding up better on web than on mobile.
56.4% of global AI web traffic (September 2026). Similarweb’s latest full breakdown, published October 12, shows ChatGPT’s share rising for a fourth straight month, from a summer low of 52.7% to 56.4%, as Gemini slipped to 25.0% (via OfficeChai). chatgpt.com remained the 5th most-visited website in the world in October.
Takeaway: ChatGPT’s recovery on the web is steady but slow – roughly a point a month.
| AI Platform | August 2026 | September 2026 |
| ChatGPT | 55.5% | 56.4% |
| Gemini | 25.6% | 25.0% |
| Claude | 9.3% | 9.6% |
| DeepSeek | 3.4% | 3.4% |
| Grok | 2.4% | 2.3% |
| Copilot | 1.6% | 1.5% |
| Perplexity | 0.9% | 0.9% |
Source: Similarweb, published October 12, 2026 (via OfficeChai). Similarweb’s October update, published November 10, put Claude at 11.5% (via FourWeekMBA).
Takeaway: even after the rebound, ChatGPT is around 15 points below where it was a year ago (71.8% in October 2025) – nearly all of it lost to Gemini and Claude.
46.4% of the global AI assistant app market (Sensor Tower, end of May 2026), with Gemini on 27.7% and Claude on 10.3%, as reported by TechCrunch.
Takeaway: on apps, ChatGPT no longer holds a majority – the first time since it launched in November 2022.
51.58% of AI chatbot referral traffic (Statcounter, October 2026), down from 79.4% in August, with Gemini on 28.86% and Perplexity on 15.04% (via The Digital Elevator). In the US, ChatGPT’s lead is narrower still: 37.10% versus Gemini’s 35.42%.
Takeaway: ChatGPT is still the biggest AI referral source for websites, but Statcounter’s October figures show a sharp swing towards Gemini and Perplexity – watch whether it holds before rewriting your AI search strategy around it.

Takeaway: whatever the share numbers say, ChatGPT is still the AI service people visit most.
OpenAI’s crawl-to-referral ratio improved to 309:1 in Q3 2026 – the best of any AI lab, versus 988:1 for Anthropic and 1,083:1 for Perplexity (Cloudflare Radar via TechnologyChecker).
Takeaway: ChatGPT now sends more traffic back to the sites it reads than any other AI lab – though still far less than Google.
OpenAI Revenue & Valuation Stats
$40 billion+ annualised revenue run-rate (mid-August 2026). CNBC reported CFO Sarah Friar told shareholders the run-rate was growing more than 20% month on month in July. Sacra estimates OpenAI reached around $50 billion in annualised revenue in September 2026, though OpenAI hasn’t confirmed a newer figure.
Takeaway: OpenAI’s revenue run-rate has more than doubled since the start of 2026.
Enterprise revenue overtook consumer revenue on August 14, 2026, and on November 4, President Greg Brockman confirmed enterprise now accounts for more than half of OpenAI’s sales (Reuters, via The Star). OpenAI entered the year at a 60/40 consumer-to-enterprise split.
Takeaway: ChatGPT is no longer mainly a consumer business – enterprise is now the growth engine.
Q2 2026 revenue: $6.7 billion, up 18% on Q1’s $5.7 billion – with an operating loss of $12.3 billion, widening from $9.3 billion.
Takeaway: revenue is growing fast, but losses are growing faster.
ChatGPT Ads: $1 billion annualised run-rate by August 31, 2026, less than 200 days after a February US launch. Ads now run in 60+ countries for Free and Go users.
Takeaway: advertising has become a billion-dollar line faster than almost any ad product in history – expect AI ads to be a big topic for marketers in 2027.
A ~$1.25 trillion valuation in the works. OpenAI is reportedly raising around $20 billion at about $1.25 trillion, scaled back from an initial plan to raise $30 billion at $1.4 trillion as AI stocks sold off (via NewsBytes). Its last closed round, in March 2026, valued it at $852 billion.
Takeaway: even after markets cooled, OpenAI’s valuation is heading well past the trillion-dollar mark.
IPO expected in 2027. OpenAI confidentially filed a draft S-1 on June 8, 2026. Asked on November 4 whether OpenAI would be IPO-ready next year, Brockman said “I think so”, and Friar told CNBC on November 6 that the Democratic gains in the US midterms hadn’t changed the plan.
Takeaway: OpenAI is letting Anthropic go first – expect its own listing in 2027.
~$278 billion of projected negative free cash flow from 2026 to 2030, per a presentation reported by the Financial Times via Reuters, against revenue forecast to rise from $36 billion this year to $350 billion in 2030.
Takeaway: OpenAI is betting the farm on compute – profitability isn’t expected until around 2030.
Other Recent ChatGPT Developments
- GPT-6 Astra launched on September 3, 2026, followed by cheaper GPT-6 Sol and Luna models on September 22. Demand was high enough that OpenAI paused new $200 Pro sign-ups on September 10.
- Dots, an always-on ChatGPT agent, and a new $500/month Pro tier were announced at DevDay.
- ChatGPT Atlas, OpenAI’s standalone browser, was shut down on August 9, 2026, with its features folded into the ChatGPT desktop app.
- ChatGPT for Teens launched globally on August 18, 2026, with stronger content protections and parental controls.
Takeaway: OpenAI’s product focus has shifted firmly from chat to agents that do work on your behalf.
The Bigger Picture
As of November 2026, ChatGPT is still the biggest AI product in the world – 1.2 billion weekly users, a $40 billion+ revenue run-rate, a billion-dollar ad business, and a share of AI web traffic that’s rising again. Enterprise is now OpenAI’s main business, and a trillion-dollar-plus valuation is in reach.
The competition is closer than ever, though. Gemini has passed 1 billion users and is gaining fast on referral traffic, Claude leads in US business adoption and is about to go public first, and Meta Muse has shown how quickly a new AI agent can scale. The markers to watch now are OpenAI’s new funding round, how the market receives Anthropic’s IPO, and whether ChatGPT can keep clawing back web share.
