ChatGPT Regains Dominance: Web Traffic Share Hits 55.5% as Gemini’s Surge Fades
ChatGPT has clawed back to 55.5 percent of web traffic share among major AI chatbots, reversing a brief dip that saw Google’s Gemini peak at 22 percent. The recovery underscores OpenAI’s staying power as users return after a seasonal slump.
The data, drawn from Similarweb and analyzed by a third-party researcher, tracks monthly visits to the leading AI chatbot platforms. ChatGPT’s share hit a low of 48.6 percent in February 2025 before rebounding sharply in March and April.
Gemini’s rise proved temporary. It jumped from 15.5 percent in January to 22 percent in February, but then fell back to 17.5 percent by April.
The Lede: Who, What, When, Why
- Who: OpenAI’s ChatGPT and Google’s Gemini are the main competitors in this analysis.
- What: ChatGPT’s web traffic share climbed back to 55.5 percent in April 2025.
- When: The shift occurred over the first four months of 2025.
- Why: The February dip was likely a seasonal effect, not a fundamental loss of users. Gemini’s February spike appears to have been a one-time event.
How the Numbers Shifted
Monthly visits to ChatGPT’s web platform fell from 3.7 billion in January to 3.1 billion in February. But by April, traffic rebounded to 3.8 billion, setting a new record for the platform.
Gemini’s visits peaked at 1.8 billion in February, then dropped to 1.3 billion by April. The absolute numbers show that while Gemini gained share temporarily, it did not sustain the growth.
Why ChatGPT Recovered
Multiple factors explain the rebound. OpenAI’s product updates likely played a role. The company launched GPT-4 Turbo in April 2025, reportedly improving speed and accuracy.
Seasonal patterns also matter. February typically sees lower traffic across many web services. The dip was not unique to ChatGPT.
User loyalty remains strong. Despite growing competition, ChatGPT’s brand recognition and ecosystem (including plugins and DALL-E integration) keep users returning.
What Gemini’s Decline Means
Google’s chatbot failed to hold its February surge. The spike may have been driven by marketing or a temporary news cycle, rather than sustainable user acquisition.
Gemini’s integration into Google Search and other products hasn’t translated into a leading web chatbot position. Users still prefer ChatGPT for standalone conversations.
The Broader Market Picture
- Perplexity AI held steady at around 3.5 percent share.
- Claude (Anthropic) remained below 5 percent.
- Microsoft Copilot saw a slight decline to 8.5 percent.
No other chatbot has broken the duopoly of ChatGPT and Gemini. The top two platforms control over 73 percent of all web traffic to AI chatbots.
What This Means for Users
For everyday users, ChatGPT remains the default choice. Its reliability and feature set outweigh the appeal of newcomers. The data suggests that switching costs are real: once users settle into a chatbot, they rarely leave.
For developers and businesses, the takeaway is clear: investment in ChatGPT’s ecosystem is still the safest bet for reaching the largest audience.
