OpenAI says ChatGPT is expected to reach 700 million weekly active users this week—an impressive climb from 500 million reported at the end of March. In a post on X, Nick Turley, OpenAI’s vice president and head of the ChatGPT app, celebrated the milestone and the fourfold growth over the past year.

The surge signals ChatGPT’s continued success as a consumer app and its growing integration into daily life. Market watchers emphasize that this level of adoption mirrors some of the fastest growth trajectories ever seen in consumer software.

Meanwhile, renewed figures from Reuters highlight that OpenAI has also reached $12 billion in annualized revenue, driven in part by the expanded user base spanning both individual and business customers.
