ChatGPT is losing market share as Google Gemini gains ground
New data suggests that ChatGPT is losing its market share to Gemini on the web. It’s unclear if Gemini is also gaining ground in the mobile space.
In a new report, website analytics company SimilarWeb reports that ChatGPT’s market share dropped to 65% in January, which is approximately 20% lower than its 86% share in January 2025.
SimilarWeb data shows that Gemini surpassed the 20% share benchmark, while Grok surpassed 3% and is approaching DeepSeek.
| Time | ChatGPT | Gemini | DeepSeek | Grok | Perplexity | Claude | Copilot |
|---|---|---|---|---|---|---|---|
| 12 Months Ago | 86.7% | 5.7% | – | – | 1.9% | 1.5% | 1.5% |
| 6 Months Ago | 78.6% | 8.6% | 4.8% | 2.1% | 1.6% | 1.5% | 1.1% |
| 3 Months Ago | 74.1% | 12.9% | 3.7% | 2.0% | 2.4% | 2.0% | 1.2% |
| 1 Month Ago | 68.0% | 18.2% | 3.9% | 2.9% | 2.1% | 2.0% | 1.2% |
| January 2026 | 64.5% | 21.5% | 3.7% | 3.4% | 2.0% | 2.0% | 1.1% |
The data also reveals that fewer people use AI tools during the holidays.
For example, over the last few weeks, the daily average visits to all tools dropped to August-September levels. As people return to work, numbers are climbing back.
Regardless, it’s quite obvious that ChatGPT is finally starting to lose popularity, as other options are now slowly catching up.
In fact, independent tests have shown that Claude Code is far better than ChatGPT for complex code, while Gemini wins in AI images with realistic quality.
Meanwhile, OpenAI has been internally mulling a strategy to roll out ads on ChatGPT.
We haven’t seen ads on ChatGPT because the company fears that ads could upset its loyal audience, especially at a time when consumers are finding Gemini to be better.
