Key Takeaways
- 900 million weekly active users as of February 2026 – bigger than the US and EU combined.
- ChatGPT grew 200% in 12 months, from 300 million to 900 million weekly users.
- OpenAI confirmed 50 million paying subscribers in February 2026 – the first public disclosure.
- By default, OpenAI uses your chats to train its models – most users never opt out.
The Story Behind the Numbers
ChatGPT’s growth over the past year is unlike anything the internet has seen before. In early 2025, ChatGPT had 300 million weekly active users. By mid-2025, that number had grown to 700 million. By February 2026, it reached 900 million. That is a 200% increase in roughly 12 months.
To put it in perspective: 900 million people is larger than the combined population of the United States and the European Union. Every week. On one platform. OpenAI also reported 50 million paying subscribers as of February 2026 – the first time the company has publicly shared that figure. That scale fits the broader market, where 1 in 6 people on Earth used a generative AI tool in H2 2025.
This is no longer a tech experiment. ChatGPT has become mainstream digital infrastructure.
Why This Data is Important
When 900 million people use a single platform every week, it is worth understanding what that means for your personal data.
By default, OpenAI uses your ChatGPT conversations to improve its models. You can turn this off in settings – but most users never do. The more people rely on ChatGPT for work, health questions, or personal decisions, the more sensitive that data becomes. That concern extends beyond one platform, with 47,400+ publicly listed AI tools now creating new places where user data can be collected.
A VPN will not change what OpenAI can see in your prompts. But it does mask your IP address – the identifier that links your activity to your location and device. For users who want an extra layer of separation, hiding your IP is a straightforward starting point.
Looking Ahead: Future Outlook
From 300 million to 900 million weekly users in one year is a significant shift – and there is no sign of it plateauing yet.
More users means more data, more influence over how people find information, and more pressure on regulators worldwide. The EU’s AI Act is already responding to this shift. That pressure grows because every AI prompt can reveal personal data.
For everyday users, the question is no longer whether to use AI. It is how to use it thoughtfully.
