AI, OpenAI’s CEO, Sam Altman, recently announced a massive new milestone: ChatGPT now boasts over 800 million weekly active users. This figure, unveiled at the company’s recent DevDay keynote, confirms the platform’s incredible trajectory, transforming it from a viral sensation into one of the fastest-scaling software services in history.
“Today, 4 million developers have built with OpenAI,” Altman said. “More than 800 people use ChatGPT every week, and we process over 6 billion tokens per minute on the API. Thanks to all of you, AI has gone from something people build play with to something people build with every day.” Altman made the announcement during the keynote presentation for OpenAI’s Dev Day, which also included announcement for new tools for building apps inside of ChatGPT, as well as constructing more complex agentic systems. “This will enable a new generation of apps that are interactive, adaptive, and personalized, that you can chat with,” Altman said.
The jump to 800 million weekly active users highlights an accelerating growth rate. To put this in perspective:
- March 2025: The platform reported approximately 500 million weekly users.
- August 2025: That number was approaching 700 million.
- October 2025: The latest announcement confirms a further surge to 800 million.
This continuous, sharp acceleration underscores a critical shift: AI is no longer a curiosity; it’s an everyday utility for a significant portion of the global population.
Crossing 800 million weekly active users isn’t just a headline — it’s a turning point. ChatGPT has moved from an AI experiment to a core component of how people, organizations, and developers interact with intelligence.
That said, milestones aren’t destinations. The real judgment will come in how OpenAI balances scale, reliability, security, ethics, and monetization. If they play the next moves well, they won’t just be the most used AI tool — they’ll define how AI is woven into everyday life.
As AI moves from “something people play with to something people build with every day” (as Sam Altman noted), the sheer scale of ChatGPT’s user base ensures it will remain at the forefront of this transformative technological era. The question now isn’t if AI will change the world, but rather how quickly and completely it will do so.
