ChatGPT at scale: How fast it’s growing
When ChatGPT launched on November 30, 2022, it became the fastest-growing app in history - reaching 1 million users in just 5 days and 100 million within two months.
By early 2025, growth had gone exponential. ChatGPT had 400 million users, 15.5 million Plus subscribers, and 1.5 million enterprise customers, handling more than 1 billion queries every day.
And it didn’t stop there, by July 2025, ChatGPT reached 700 million weekly active users, and by September 2025, OpenAI’s CEO Sam Altman confirmed it had surpassed 800 million weekly users, nearly 10% of the world’s adult population.
Traffic data confirms the dominance: ChatGPT.com receives over 5 billion visits per month and ranks as the #5 most visited website globally.
Users are highly engaged, too:
To put this in perspective, ChatGPT users send over 2.5 billion prompts per day. That’s more than 28,000 prompts every second!

Users are highly engaged, too:
- each session lasts an average of 13 minutes and 34 seconds,
- the bounce rate is just 37.07%.

💡 Growth Tip:
These numbers show why ChatGPT has become its own search ecosystem. If you want to stay visible inside AI-generated answers and summaries, optimize for platforms like Google AI Mode and AI Overview. That’s where search traffic is heading next.

Who uses ChatGPT (and where)
In just two years, ChatGPT usage has gone from being tech-heavy and male-dominated to broad, balanced, and global.
At launch, ChatGPT’s user base leaned heavily male - about 80% of early users had typically masculine first names. But by mid-2025, that gap had completely closed, with women slightly more represented at 52% of active users.
Age patterns have shifted too. Nearly half of all ChatGPT messages are now sent by users under 26, but usage is growing across every age group. That’s a strong sign that generative AI isn’t just for students or professionals - it’s becoming part of everyday digital life.
Geographically, the platform is expanding fastest in places you might not expect. By May 2025, ChatGPT adoption in low-income countries was growing 4x faster than in high-income ones. That’s a big shift - it means the AI revolution is becoming truly global, not just concentrated in the U.S. or Europe.

💡 Growth Tip:
AI tools like ChatGPT are globalizing how people find and process information. If your website serves multiple markets, this is your cue to start thinking about international SEO - language targeting, localized schema, and regional search intent.

How people actually use ChatGPT
So what are 800 million people actually doing with ChatGPT every week? Turns out, most of us aren’t coding - we’re asking, writing, and learning.
According to OpenAI’s usage study, nearly 80% of all ChatGPT conversations fall into three broad categories:
Of these, writing leads the pack (especially at work) accounting for 40% of work-related messages as of mid-2025. Interestingly, about two-thirds of these writing tasks involve improving user text (editing, critiquing, translating) rather than creating new content from scratch.
Meanwhile, Practical Guidance makes up roughly 29% of all use, and Seeking Information has doubled from 14% to 24% in just one year. Today people are treating ChatGPT as an advisor, not just a writing assistant.
The “intent” mix of ChatGPT conversations is equally revealing:
And over time, the “Asking” share is growing fastest - up from 50% to 51.6% by mid-2025, while “Doing” has dropped to 34.6%.
About 30% of total ChatGPT usage is work-related, while 70% happens outside work. When people use it for their jobs, 81% of messages connect to high-level activities like getting information, making decisions, and solving problems.
According to OpenAI’s usage study, nearly 80% of all ChatGPT conversations fall into three broad categories:
- Practical Guidance – tutoring, how-to advice, brainstorming, and creative ideation.
- Seeking Information – research, product comparisons, recipes, and fact-checking.
- Writing – emails, reports, editing, translating, and content creation.

The “intent” mix of ChatGPT conversations is equally revealing:
- 49% Asking - people seeking help, advice, or clarity
- 40% Doing - task-focused requests like writing, planning, or coding
- 11% Expressing - reflection, exploration, and play.

💡 Growth Tip:
If you’re creating content or services for professionals, think about this: your audience already uses ChatGPT to get advice and compare answers. The better your site’s structure, schema, and clarity, the more likely it is to be cited or summarized inside AI platforms. Start exploring that shift with Answer Engine Optimization (AEO).

ChatGPT in business & enterprise
ChatGPT is becoming a standard part of business operations, from small startups to Fortune 500 companies.
Data shows that 49% of U.S. companies are already using ChatGPT in some capacity. Even more impressive, over 2 million businesses worldwide have now integrated it into their workflows.
That makes ChatGPT the most widely adopted AI tool across both home and workplace environments. Among AI users 83.27% use ChatGPT at home, 70.8% use it at work.
About 1 in 4 businesses reported savings between $50,000 and $70,000 by using ChatGPT to streamline tasks like content writing, support automation, and data analysis.

Costs, energy & scale behind ChatGPT
Behind every ChatGPT answer is a serious amount of computing power and cost. Training and running these large language models isn’t cheap or simple, and the numbers behind them show just how massive the infrastructure really is.
When OpenAI trained GPT-3, it reportedly cost around $12 million for a single training run. By comparison, training GPT-4 cost roughly $100 million - nearly 10 times more. These are investments on a scale that only a few organizations in the world can handle.
Operating ChatGPT is also energy-intensive. Each 5 to 50 prompts answered uses about 500 milliliters of water - that’s the cooling requirement for the supercomputers that power the model. As usage keeps growing, that environmental cost is becoming part of the AI conversation.
Financially, OpenAI ranks among the most funded machine-learning companies in the world, with over $1 billion in funding as of January 2023. Considering its user base now exceeds 800 million weekly active users, that funding has clearly paid off - but sustaining it at scale will depend on efficiency, infrastructure, and continued innovation.

What these ChatGPT statistics mean for businesses
Today, customers don’t just type keywords into Google. They ask full questions inside AI platforms like ChatGPT, Google AI Mode, or Gemini - and expect clear, contextual answers. That shift is exactly why strategies like Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO) matter more than ever.
Here’s how these ChatGPT statistics connect directly to business growth:
Here’s how these ChatGPT statistics connect directly to business growth:
- 800M weekly users means your audience is already here. Treat ChatGPT as a discovery channel, not just a productivity tool.
- The 2M+ businesses using ChatGPT show how fast companies are integrating AI into workflows. If you’re not, your competitors probably are.
- The fact that 49% of U.S. companies already use ChatGPT highlights how AI + SEO integration is now standard, not experimental.
- With 74.7% chatbot market share, ChatGPT has become an ecosystem of its own - much like search engines did 20 years ago.
