ChatGPT reclaims 55.5% of AI chatbot web traffic as Gemini's rebound fades

Similarweb traffic data reported by The Decoder shows ChatGPT clawing back web traffic share: it now accounts for 55.5% of visits to AI chatbot websites, up from 52.7% three months earlier. Google Gemini, which had staged a strong comeback, is slipping again, down to 25.6% from a recent peak of 27.8%. Looked at year over year, the picture is different: ChatGPT's share has fallen sharply from 73.3% a year ago, even after its recent recovery. Gemini's share has doubled over the same period, and Anthropic's Claude has grown from 1.9% to 9.3%. The rest of the field remains small: DeepSeek holds 3.4%, Grok 2.4%, Microsoft's Copilot 1.6%, and Perplexity 0.9%.

The article stresses that these numbers cover website traffic only, and that this likely undercounts Gemini and ChatGPT usage. Google can route many mobile Gemini interactions through its Android ecosystem, for example by sending push notifications that open the Gemini app directly with a summary instead of a web link, so that activity never shows up in web-traffic measurements. OpenAI, similarly, is pushing its mobile ChatGPT app and a new desktop version called ChatGPT Work, neither of which is captured by these website-traffic figures either.

Key facts

  • ChatGPT's share of AI chatbot website traffic rose to 55.5%, up from 52.7% three months earlier, per Similarweb data cited by The Decoder.
  • Google Gemini's share fell to 25.6% after a comeback that had briefly pushed it to 27.8%.
  • Year over year, ChatGPT's share is down sharply from 73.3%, even with its recent gains.
  • Anthropic's Claude grew from 1.9% to 9.3% year over year, while Gemini's share doubled over the same period.
  • DeepSeek (3.4%), Grok (2.4%), Copilot (1.6%) and Perplexity (0.9%) remain minor players by this measure.

Why it matters

The numbers put a figure on a shift that has been visible anecdotally: ChatGPT's dominance of AI chatbot usage has eroded a lot over the past year, even though it has clawed back some ground in the last three months. A year-over-year drop from 73.3% to 55.5% is a large swing in a market this young, and it comes alongside real gains for both Gemini and Claude, meaning the recovery is happening against genuine, not just cyclical, competition.

Who it affects

The comparison covers the leading consumer AI chatbots: OpenAI's ChatGPT, Google's Gemini, Anthropic's Claude, and smaller players DeepSeek, Grok, Copilot and Perplexity. It matters most to OpenAI and Google, whose shares are moving in opposite short-term directions, and to Anthropic, whose Claude has grown roughly fivefold in share over the year even though it is still a small slice of overall traffic.

How to use it

The figures are a snapshot of relative standing, not a definitive market map. Anyone citing them should note the metric precisely: it is a percentage share of website traffic among AI chatbots, not total users, sessions or revenue, and the three-month and year-over-year comparisons are relative-time windows without stated calendar dates.

How solid is it

The data is attributed only to Similarweb, with no named analyst or company spokesperson quoted, and The Decoder does not disclose the underlying visit or session counts behind the percentages. The figures measure website traffic specifically, which the article itself flags as an incomplete picture of actual usage.

Risks and caveats

The article's own caveat is the important one: website traffic misses substantial app-based usage. Google can route mobile Gemini interactions through Android push notifications that open the Gemini app with a summary and never touch the web, and OpenAI is pushing both a mobile ChatGPT app and a new desktop app, ChatGPT Work, neither of which shows up in these stats. That means Gemini's and ChatGPT's real usage shares could both be understated relative to what website-only figures suggest, and the article gives no reason for why Gemini's comeback happened or why it is now fading again.
