ChatGPT Surges to 700 mn Weekly Users, Quadruples Growth in a Year
OpenAI reports three million paying business clients as of March 2025
ChatGPT is on track to surpass 700 million weekly active users this week—up from around 500 million at the end of March and a staggering 4× increase year-over-year, according to Nick Turley, OpenAI’s VP & head of the ChatGPT app. That rapid rise underscores ChatGPT’s emergence as one of the fastest-growing consumer applications ever.
With its user base scaling so quickly, usage figures have surged alongside: ChatGPT now processes over 2.5 billion prompts daily, including 330 million from U.S. users alone. Meanwhile, OpenAI’s annualised revenue has doubled to approximately $12 billion, despite a projected cash burn of around $8 billion in 2025.
Earlier this year, OpenAI’s Chief Operating Officer, Brad Lightcap revealed that ChatGPT crossed an impressive 400 million weekly active users (WAU), with over 2 million business users leveraging the tool for work.
The platform now supports a diverse community of individual and enterprise users, with over 3 million business customers and paid subscriptions on the rise—OpenAI reports three million paying business clients as of March 2025.
“Every day, people and teams are learning, creating, and solving harder problems. Big week ahead,” Turley wrote, expressing gratitude to OpenAI’s team for “making ChatGPT more useful and delivering on our mission so everyone can benefit from AI.”
As usage and revenue surge, ChatGPT is reshaping how organizations and individuals access information—shifting behaviors away from legacy search engines and redefining digital productivity.
Recently, OpenAI CEO Sam Altman issued a stark warning: conversations with ChatGPT are not legally private, even when used for therapy or emotional support.
Unlike human professionals—therapists, lawyers, or doctors—interactions with AI lack legal protections like doctor-patient or attorney-client privilege.
