OpenAI's ChatGPT has reached an estimated one billion global monthly active app users, marking one of the fastest adoption curves in consumer technology history.
According to estimates from market intelligence firm Sensor Tower, ChatGPT crossed the one-billion monthly active users mark in May — roughly three years after launch, Reuters reported on Tuesday.
The platform has outpaced the growth trajectories of apps including TikTok, Instagram, YouTube and Google Maps.
While ChatGPT dominates in overall reach, rival AI startup Anthropic is showing signs of rapid momentum.
Sensor Tower estimates Claude reached 56 million global monthly active app users in the second quarter to date.
The company's app recorded year-over-year monthly active user growth of roughly 640%, significantly faster than ChatGPT's estimated 62% growth rate over the same period.
The battle for AI users is increasingly translating into competition for engagement.
Sensor Tower said U.S.-based ChatGPT users who installed Claude during the first quarter spent about 5% less time using ChatGPT one month later than their average usage over the previous eight months.
The rivalry also comes as both companies appear to be moving closer to public markets. Anthropic confidentially filed for a U.S. initial public offering on Monday, while reports indicate OpenAI could file for an IPO in the coming weeks.
