ChatGPT Continues to Dominate Search Market with Mega 80% Share

It looks like the world of search is being taken over by AI, and ChatGPT might be a good reason to blame.

Classic search engines are witnessing a general decline, while ChatGPT is leading the race of AI search with a mega 80% share as per recent stats published by Similarweb. It shared how the past six months saw OpenAI’s tool maintain a strong lead despite the ups and downs that came its way.

The classic search engines are struggling in terms of growth as AI tools begin to reshape how users look for data online. As far as today’s image is concerned, ChatGPT’s market share keeps rebounding to 80%, while one month ago, it was 77%. The AI giant continues to dominate while others just sit and watch from afar.

Classic search engines decline steadily, while ChatGPT surges, reshaping how users find and interact with online information.

DeepSeek is down to 6.5% while Google’s AI networks stand at 5.6%, and Perplexity has hit 1.5% while Grok witnesses 2.6%. These figures are part of the bigger AI global picture, which was rolled out by Similarweb. Classic search engines keep losing market share, and one of the most important findings is that classic search engines aren’t growing fast enough. From Google and Bing to Yahoo, Baidu, and DuckDuckGo, it’s on the losing end of things.

Classic search displayed a steady fall of 1 to 2% when compared to data seen in the previous year. It’s crucial to mention how Google has seven times as the users as ChatGPT but yet the latter is picking up the pace to become the front runner.

AI is really altering the world of search, and some AI domains are experiencing faster growth than the next. Common examples include growth in general AI tools, voice generators, music generators, and DevOps with Code completion. Furthermore, some AI domains are getting smaller, like content generation, client support, and legal AI.

You need to remember it’s now only the world of search that’s getting impacted by AI. So many other digital sectors face major changes, like Education tech, freelance domains, and website builders. Right now, design platforms continue to grow 10% YOY, and that might hint at how AI assists instead of replacing the services.

Does this mean classic SEO matters or not? The answer is that it’s just not enough. Classic search traffic keeps falling, and you need to branch out.

The data produced in this report shows how constant negative growth for classic search engines, along with ChatGPT’s leading market position, hints at a huge shift in data discovery. So the take-home message here is to make the most of AI-based search while ensuring practices that work in classic search. This balance will lead to success for search marketers in 2025 and even further.
