OpenAI’s ChatGPT has reportedly reached 1 billion monthly active users worldwide, making it the fastest app to achieve this milestone, according to estimates from market research firm Sensor Tower.
The app reached this mark in May, about three years after its mobile launch. Its growth has been faster than popular apps like Google Maps, TikTok, Instagram, and YouTube.
However, this number has not been officially confirmed by OpenAI and is currently based on third-party estimates.
ChatGPT was launched on iPhones in May 2023 and on Android devices in July 2023, helping it quickly reach users around the world.
At the same time, competition in the AI market is increasing. Anthropic’s Claude AI app reportedly had around 56 million monthly active users, although ChatGPT remains far ahead in total users.
According to Sensor Tower, some users who started using Claude spent slightly less time on ChatGPT, showing growing competition between AI platforms.
The milestone comes as technology companies continue investing heavily in artificial intelligence. AI has become a major focus at industry events such as Google I/O and Microsoft Build.
There are also reports that both OpenAI and Anthropic are preparing for stock market listings (IPOs) in the future.
If OpenAI confirms the 1 billion-user milestone, it would further strengthen ChatGPT’s position as the world’s leading consumer AI application.
