ChatGPT hits a billion monthly app users despite souring public AI sentiment

ChatGPT reached one billion monthly active users (regular monthly visitors) in May 2024, making it the fastest app ever to hit this milestone in roughly 3.5 years since launch. Despite growing public concern about AI risks from figures like the Pope and tech leaders, AI app usage continues to surge, with competitors like Claude and Meta AI growing much faster than ChatGPT year-over-year, though ChatGPT still leads overall.
