3 years old, 800 million users, 29,000 prompts a second: ChatGPT's meteoric rise, by the numbers

In a remarkable journey since its launch, ChatGPT has rapidly evolved into one of the most popular technologies today, boasting an astonishing 800 million weekly active users as of September 2025. Initially launched in November 2022, the AI chatbot has transformed the way individuals and businesses interact with technology, establishing OpenAI as a frontrunner in the artificial intelligence landscape. The rise of ChatGPT has been nothing short of meteoric. Users have crafted millions of custom iterations, expanding its capabilities far beyond simple text responses. ChatGPT is now accessible in over 150 countries and has significantly impacted OpenAI's valuation, which surged to nearly $500 billion, making it one of the most valuable startups in history. As of July 2025, users were sending a staggering 18 billion messages weekly, averaging about 29,000 messages per second. This surge in interaction reflects a shift in user behavior, with non-work-related communications rising dramatically from 53% in June 2024 to 73% by mid-2025. This indicates that ChatGPT is not just a tool for productivity, but also a significant player in personal and recreational communication. OpenAI has continually improved ChatGPT's functionality, transitioning from the initial GPT-3.5 model to the more advanced GPT-5, which debuted in 2024. The latest model promises enhanced performance in various tasks, including writing, coding, and health inquiries, while minimizing inaccuracies and improving user experience. Interestingly, the user demographic has also evolved. Initially dominated by users with masculine names, the gender gap has nearly closed, with women now slightly outnumbering men on the platform. This shift suggests broader acceptance and utilization of the technology across diverse user groups. Further solidifying its position in the market, OpenAI announced in November 2025 that it had reached one million business customers. These organizations utilize ChatGPT for various purposes, either through dedicated business platforms or direct model consumption. As ChatGPT continues to innovate and expand its features, such as AI-driven shopping and group chat capabilities, its impact on everyday life and work environments is profound. With more than 3 million custom versions created by users, the chatbot is redefining how people interact with AI, making it an integral part of modern communication.
