ChatGPT Nears 900 Million Weekly Active Users But Gemini is Catching Up

The competition between AI chatbots has been heating up, with Google’s Gemini nipping at OpenAI’s heels. On Monday, I wrote about how Gemini’s share of weekly mobile app downloads increased in late November following the release of Gemini 3, according to data from research firm Sensor Tower, which says it tracks 5 million consumers globally. 

Gemini’s growth is also evident on the web. Between August and November, Gemini’s global website visits doubled while ChatGPT’s rose about 1% over the same period, according to the Sensor Tower data. Monthly active users tell a similar story during the period: Gemini’s increased roughly 30% to 346 million while ChatGPT’s rose about 5% to 810 million. 

These figures explain why OpenAI CEO Sam Altman called an internal “code red” to focus on ChatGPT and delay other initiatives.
