AI now has more than a billion users on more than one platform. ChatGPT reaches 1.2 billion people a week, the Gemini app has passed 1 billion monthly users, and Google’s AI Overviews reach 2.5 billion people every month.
Behind those numbers, the market is maturing fast. Nearly one in five working-age people worldwide now use generative AI, more than half of US businesses on Ramp’s platform pay for it, and global AI spending is forecast to hit $2.67 trillion this year. At the same time, the leading labs are closer than ever: Anthropic has overtaken OpenAI in US business adoption, Gemini owns a quarter of AI web traffic, and ChatGPT’s share has stabilised after a year of decline.
This post pulls together the most important AI usage statistics available as of October 2026: how many people use AI, which platforms they use, how businesses are adopting it, and where the money is going.

How Many People Use AI in 2026?
18.8% of the world’s working-age population (aged 15-64) used generative AI in Q2 2026, up from 17.8% in Q1, according to Microsoft’s Global AI Diffusion Report (September 2026). Usage rose in almost every economy measured.
Takeaway: nearly one in five working-age people worldwide now use AI – roughly 940 million people.
AI use is 28.8% in the Global North and 16.2% in the Global South, and the gap widened from 12.1 to 12.6 percentage points in a single quarter.
Takeaway: AI is spreading everywhere, but it’s spreading fastest where adoption is already highest.
AI Adoption by Country

Perplexity’s referral share has fallen from 12.07% in April 2025 to 4.31%. More in our Perplexity AI Stats post.
Takeaway: Perplexity is losing referral share even as its revenue grows quickly.
Business & Enterprise AI Adoption
Nearly 9 in 10 organisations use AI in at least one business function, and 44% say AI is now scaling across the enterprise (up from 38%), per McKinsey’s State of AI 2026 survey (1,719 respondents, 97 countries, published August 2026).
Takeaway: the move from AI pilots to company-wide rollouts is finally happening.
56% of organisations now use AI in three or more business functions, up from 51% a year earlier.
Takeaway: AI is spreading beyond IT and marketing into the rest of the business.
Only 37% of respondents attribute any EBIT impact to AI, roughly the same as a year earlier.
Takeaway: adoption is up, but proving bottom-line value is still the hardest part.
56.1% of US businesses on Ramp’s platform paid for AI in August 2026, while the US Census Bureau’s survey put business AI use at 22.1%.
Takeaway: the answer to “how many businesses use AI?” depends heavily on who you ask – Ramp’s tech-leaning customer base adopts much faster than the average US firm.
80.6% of US technology and media businesses now pay for AI tools, followed by finance and insurance at 73.1% and manufacturing at 60.4% (Ramp data, via Benzinga).
Takeaway: AI is no longer just a tech-sector tool – finance and manufacturing are catching up fast.
43.8% of US businesses on Ramp paid for Anthropic in August 2026, versus 39.8% for OpenAI, according to the Ramp AI Index.
Takeaway: in business adoption, Claude has overtaken ChatGPT – the opposite of the consumer picture.
The effective price of AI fell 41%, from $1.15 to $0.68 per million tokens, between March and September 2026, and top-spending firms cut per-employee AI spend by 9.7% in August.
Takeaway: AI is getting much cheaper, and businesses are switching to cheaper standard models wherever they can.
The Money: Revenue, Valuations and IPOs
Worldwide AI spending is forecast to reach $2.67 trillion in 2026, up 49.5% from $1.79 trillion in 2025, with infrastructure making up around $1.48 trillion, according to Gartner’s September forecast, as reported by THE Journal. Gartner expects $3.64 trillion in 2027.
Takeaway: more than half of all AI spending is going on data centres and chips, not software.
| Company | Latest Revenue Run-Rate | Latest Valuation | IPO Status |
| OpenAI | $40B+ (mid-Aug 2026) | $852B | Expected 2027 |
| Anthropic | $65B+ (late Jul 2026) | $965B | Nasdaq chosen; timing unconfirmed |

Takeaway: on the latest confirmed figures, Anthropic’s run-rate is ahead of OpenAI’s – though unconfirmed reports suggest OpenAI’s may have jumped to around $70 billion by late September.
Anthropic reported its first profitable quarter in Q2 2026 (on an adjusted operating basis), and has told shareholders it expects a second in Q3. Full details in our Claude AI Stats post.
Takeaway: the first frontier AI lab to turn an adjusted profit isn’t the biggest one.
OpenAI’s enterprise revenue overtook its consumer revenue on August 14, 2026, and its ChatGPT ad business hit a $1 billion run-rate in under 200 days. See our ChatGPT Stats post.
Takeaway: the AI business model is shifting from consumer subscriptions to enterprise contracts and advertising.
Google Cloud revenue grew 82% to $24.8 billion in Q2 2026, with a $514 billion backlog. Our Google Gemini Stats post has the full breakdown.
Takeaway: Google is turning Gemini into one of the fastest-growing cloud businesses on record.
SpaceX’s AI segment (Grok and X) grew revenue 247% year on year to $2.56 billion in Q2 2026, mostly from selling compute. More in our Grok AI Stats post.
Takeaway: Grok’s parent makes most of its AI money from infrastructure, not chatbot subscriptions.
The Rise of AI Agents
AI agents – tools that carry out multi-step tasks rather than just answer questions – are the fastest-moving part of the market.
40% of organisations with $1 billion+ in revenue are now scaling AI agents, up from 27% a year ago, while smaller organisations are flat at 22% (McKinsey, 2026).
Takeaway: big companies are pulling ahead on agents – smaller firms risk getting left behind.
OpenAI’s AI coding and work products (including Codex) reached 20 million weekly users, and OpenAI launched Dots, an always-on ChatGPT agent, at DevDay in September 2026.
Takeaway: agents have gone mass-market in under a year.
Claude Code is running at a $2.5 billion+ run-rate (latest official figure) with 2 million+ weekly users, and Barclays expects half its developers to use it by the end of 2026.
Takeaway: coding agents are now one of the biggest revenue lines in AI.
OpenClaw, the open-source agent, has 390,570 GitHub stars and around 13.5 million monthly npm downloads, making it the most-starred software project on GitHub. Full story in our OpenClaw AI Stats post.
Takeaway: the agent boom isn’t just coming from the big labs – open source is a huge part of it.
SpaceXAI’s Grok Bot agent reached 418,000 users within about a month of launch, and Perplexity Computer now runs inside Microsoft 365.
Takeaway: every major AI company now has an agent product.
AI Usage Statistics October 2026: Key Takeaways
As of October 2026, AI has crossed into true mass adoption: two billion-user consumer products, nearly one in five working-age people using generative AI, and more than half of tech-forward US businesses paying for it.
The platform picture has settled into a clear shape. ChatGPT leads on reach and referral traffic, Gemini leads on distribution through Search and Android, and Claude leads on business adoption and revenue growth. Grok, Perplexity and DeepSeek are fighting for what’s left.
The next few months have three clear things to watch: whether ChatGPT’s web-share rebound holds, how Anthropic’s IPO is received, and whether falling AI prices squeeze the frontier labs’ revenue growth.
