OpenAI’s rivals are gaining on its flagship product. ChatGPT's early lead among individual users appears to be shortening as rivals like Google’s Gemini close in on its app and web market share—a shift that could complicate the company’s reported plans to IPO later this year.
OpenAI’s ChatGPT app market share plummeted from 69.1% in January 2025 to 45.3% the following year, according to data from mobile intelligence data
provider Apptopi. Over the same period, Google’s Gemini chatbot app increased its market share from 14.7% to 25.2%. It’s not just OpenAI’s app market share that has taken a hit; rivals have also been gaining in terms of web traffic. On the enterprise front, Anthropic has been showing significant momentum. According to one
survey, the AI lab holds
about a third of the enterprise market, compared with 25% for OpenAI and about 20% for Google Gemini.
The trends paint a picture of an increasingly competitive AI landscape with OpenAI facing challenges on multiple fronts: losing consumer market share to Google’s Gemini, contending with Anthropic’s enterprise momentum, and navigating fast-growing competitors like xAI’s Grok. If ChatGPT’s consumer market share continues to drop, that could complicate OpenAI’s potential IPO plans—especially if Anthropic, which is reportedly considering going public, manages to go public ahead of them.—
