ChatGPT remains the most popular chatbot worldwide, but Google's Gemini is quickly catching up

​While OpenAI’s ChatGPT maintained the first-mover advantage in the AI ​​market for a while, it soon had enough competition in the field, not only from American competitors such as Google’s Gemini and xAI’s Grok, but also from Chinese such as Qwen and DeepSeek. However, the latest data shows that ChatGPT is still the most popular chatbot on the market, although its popularity has steadily declined over the past year. According to the latest SimilarWeb data, there has been a 13 percentage point drop in ChatGPT market share over the past 12 months, suggesting that the competition is finally starting to chip away at OpenAI’s overwhelming lead. Meanwhile, Google Gemini, which recently had a viral moment with its Nano Banana model, is now firmly in second place and has gained significant market share in the last few months. Another winner was Aravind Srinivas-led Perplexity AI, which steadily gained ground from 1.7% a year ago to 2.4%, according to the latest data. Meanwhile, the biggest loser was DeepSeek, which peaked at 6.8% about six months ago and took second place in the AI ​​market. Since then, however, the Chinese AI model has slowly lost ground and today stands at 3.7%. ​DeepSeek had a viral moment of its own at the start of the year when its global launch shattered all notions of Western supremacy in the AI ​​race. Since then, DeepSeek has not been able to repeat similar success with a large model launch, while OpenAI, Google and others have launched new models one after another, and even Chinese competitors such as Qwen have become popular on social media.

The data shows that Grok AI peaked at 3.1% about six months ago and has fallen to 2.0% as of today, falling even behind Perplexity. The data also shows that Microsoft’s Copilot remained relatively steady, from 1.1% to 1.2%, while Anthropic’s Claude registered a slight increase, from 1.7% to 2.0% in the 12-month period. As of today, October 19, ChatGPT has a market share of 74.1%, followed by Gemini at 12.9%, DeepSeek at 3.7%, Perplexity at 2.4%, Claude at 2.0%, and Copilot at 1.2%.
