One assistant grew its web traffic about 306% in a single quarter. That is Claude, which went from roughly 203 million web visits in January 2026 to about 824 million in April 2026, according to web-visit-share estimates reported in mid-2026. In the same window, Google Gemini quietly took the number-two spot, holding around 27.4% of worldwide web-visit share after roughly doubling β up about 104% in six months. The AI assistant race is no longer a one-horse story.
It is still a race ChatGPT leads. It crossed roughly 1 billion users earlier in 2026 and remains the default for most people who type a question into a chatbot. But the share numbers underneath that lead are moving fast, and they tell you where the next year of competition is heading. One caveat before the numbers: web-visit share is a single metric. It measures traffic to websites, not app installs, paying customers, or revenue. Treat it as one lens, not a scoreboard.
The leaderboard right now
| Assistant | Web-visit share | Recent growth | Why |
|---|---|---|---|
| ChatGPT | Clear overall leader (~1B users) | Steady, lead by scale | First-mover, brand, default habit |
| Google Gemini | ~27.4% | ~104% in six months | Distribution through Search, Android, Workspace |
| Claude (Anthropic) | ~8.2% worldwide | ~306% in one quarter | Coding, agents, enterprise; smaller base |
These are web-visit-share figures (SimilarWeb-style estimates), not user counts or revenue. A small base can produce a huge percentage jump, and a huge user base can sit on flat share. Read each column for what it is.
Why Gemini is climbing
Google did not win second place by building a better chatbot than everyone else. It won by putting Gemini where people already are. Search, Android, Chrome, Gmail, Docs β Google ships Gemini into products that billions of people open every day without choosing to.
That is the whole story behind ~27.4% and ~104% growth in six months. When an AI answer appears at the top of a search result, or a "help me write" button sits inside the email a user was already drafting, adoption does not require a decision. It requires nothing. Default distribution is the most durable advantage in consumer software, and Google has more of it than any rival. The web-visit-share jump is what that distribution looks like when it is switched on at scale.
The risk for Google is the same as the advantage: a lot of that traffic is passive. People landing on a Gemini answer through Search are not the same as people who chose Gemini. But share is share, and right now it is climbing faster than anyone except the much smaller challenger below.
Why Claude is the fastest-growing
Claude's ~306% jump in one quarter is the most dramatic number in the data, and the asterisk matters: it started from a smaller base. Going from ~203 million to ~824 million web visits is easier in percentage terms than moving a billion-user product. The percentage is real, but so is the context.
What is driving it is narrower and stickier than mass-market chat. Claude has become a default tool for software developers, for the new wave of AI "agents" that chain together multi-step tasks, and for enterprises that care about reliable, controllable output. Agents are a defining trend of 2026 β systems that do not just answer a question but carry out a sequence of actions β and that work tends to route through models built for it. Anthropic has leaned into that lane. The result is a smaller share of total traffic (~8.2% worldwide) growing faster, in relative terms, than anyone else on the board.
The open question is whether Claude can convert technical and enterprise strength into the kind of everyday-consumer habit that ChatGPT and Gemini already own. The growth rate says momentum. The base size says there is a long way to go.
Why ChatGPT still leads
Strip away the share movement and one fact holds: ChatGPT passed roughly 1 billion users earlier in 2026. No competitor is close on raw scale.
The lead is built on being first and being the name. ChatGPT defined what "AI chatbot" means for most people, and that brand position is hard to dislodge even as rivals grow their share faster. When someone who has never used an AI assistant decides to try one, ChatGPT is still the default guess. First-mover advantage plus a household name plus a billion users is a deep moat, and percentage-growth charts on smaller competitors do not drain it overnight.
The honest read: ChatGPT can lose share and still lead by scale for a long time. Share shifts and absolute size are different races. ChatGPT is losing some of the first while comfortably winning the second.
The wildcard: Apple's Siri
None of the numbers above account for the largest distribution event still loading. Apple is rolling out a redesigned, AI-powered Siri in 2026, built into devices that more than a billion people already carry.
That matters because of who it reaches. The people most likely to use an AI assistant have mostly tried one already. The people who never opened ChatGPT β who find chatbots intimidating, pointless, or invisible β are exactly the people who will get a smarter Siri whether they sought it out or not. If Apple makes the everyday assistant good, it could bring AI to a population that the current leaderboard does not measure at all. None of these web-visit-share figures capture a request spoken to a phone. Siri is the variable that could redraw the map without showing up in a web-traffic chart.
What it actually means for you
There is no single winner in mid-2026, and pretending otherwise misreads the data. There is a scale leader (ChatGPT), a distribution leader gaining fast (Gemini), and a relative-growth leader with a narrower base (Claude). Pick by use case, not by headline.
If you write code, build agents, or need controllable enterprise output, Claude's traction is not an accident β that is the work it is built around. If you live inside Google's products, Gemini meets you there with zero setup. If you want the broadest, most general-purpose assistant with the largest community and ecosystem, ChatGPT remains the safe default. And if you have never tried any of them, the easiest entry point may soon be the phone already in your pocket.

The numbers will move again next quarter. The lesson holds: watch share and scale separately, and never mistake one metric for the whole race.
