ChatGPT reaches 900M weekly active users

ChatGPT has reached 900 million weekly active users, OpenAI announced Friday, putting the AI chatbot within striking distance of 1 billion. OpenAI also shared that it now has 50 million paying subscribers.

“Subscriber momentum accelerated meaningfully to start the year, with January and February on track to be the largest months for new subscribers in our history,” the company wrote in a blog post. “People use ChatGPT to learn, write, plan, and build. As usage scales, the product improves in ways people feel immediately: faster responses, higher reliability, stronger safety, and more consistent performance.”

The new weekly active user figure marks a jump of 100 million users from the 800 million that OpenAI reported in October 2025.

OpenAI shared the new numbers as part of its announcement that it has raised $110 billion in private funding, marking one of the largest private funding rounds in history. The new funding includes a $50 billion investment from Amazon, along with $30 billion each from Nvidia and SoftBank, at a $730 billion pre-money valuation. The round remains open, and the company expects more investors to join.
