ChatGPT traffic share is back at 55.5% of global visits across generative AI interfaces, up from 52.7% three months earlier. Gemini gives back most of what it gained and slides to 25.6%. Behind them, Claude went from 1.9% to 9.3% in a year, the steepest relative climb on the board.
Key Takeaways
- ChatGPT 55.5%, Gemini 25.6%, Claude 9.3% of web visits in August
- Gemini drops 2.2 points in a quarter after a comeback that did not hold
- The panel covers web traffic only, with mobile app usage left out entirely

ChatGPTThree points recovered in a single quarter
The August reading breaks a balance that had looked settled since spring. ChatGPT traffic share stands at 55.5% of global visits to generative AI interfaces, against 52.7% in the May reading. Close to three points recovered in one quarter, after twelve months of steady decline.
The move runs the other way at Google. Gemini falls back to 25.6% after touching 27.8% in the previous reading. Its year-long climb remains large, but the curve flattened exactly when the assistant looked like it was locking in momentum.
The numbers come from audience measurement firm Similarweb, whose quarterly readings of visit share across generative AI platforms serve as the sector’s shared reference, since the labs themselves publish nothing comparable.
The rest of the board fits in four lines. DeepSeek at 3.4%, Grok at 2.4%, Copilot at 1.6%, Perplexity at 0.9%. None of the four clears 5%, even though three of them sit inside groups with consumer distribution already in place. Copilot is the sharpest case: native placement inside the most widely deployed office suite in the working world still leaves Microsoft’s assistant under 2% of web visits.
Over twelve months, the OpenAI slide is still the structural number: 73.3% in summer 2025, 55.5% today. ChatGPT traffic share lost close to eighteen points in a year, and this quarter is the first interruption in that slope.
For an engineering lead, a quarterly swing like this carries one practical consequence. An audience consolidating around a dominant platform means third-party integrations, browser extensions and vendor connectors keep shipping there first. The availability gap between the leader and the runner-up stays the real hidden cost of a tooling choice, well ahead of the monthly seat price.
What the reading really confirms is a market that stops being a monopoly without becoming a duopoly. Anthropic had already passed OpenAI on the enterprise side for the first time, and the consumer picture now moves the same way, several quarters behind.
Claude multiplies its share by five in a year
The most interesting line on the board is not the first one. Claude moves from 1.9% to 9.3% of visits in twelve months. In proportional terms that beats everything else on the list, Gemini included, over the same window.
That climb did not come from a consumer campaign. It tracks professional usage spilling out of engineering teams into writing, document analysis and agent orchestration. We flagged the shift when Claude’s consumer base jumped 75% against ChatGPT.
For a team picking its stack, the read is direct. An assistant holding 9% of visit share is no longer a niche bet, it is an established secondary standard, with the integration ecosystem and documentation depth that status brings.
Monetization moves on the same track at OpenAI, which opened a 125 dollar Premium seat on its business tier. Winning back audience points and lifting average revenue are two separate motions, and the second explains part of the first: a product that segments holds its heavy users better.
On the competitive side, a firmly held third place changes the math for everyone below. A player parked above 9% captures the comparison articles, the default integrations and the enterprise test budgets, which mechanically drains the attention window left for challengers. Chinese models and European alternatives now split a residual space worth under 8% combined on this reading.
The caveat is that Claude climbs from a very low base. Going from 1.9% to 9.3% is spectacular in relative terms and far less so in absolute visit volume against the top two. The threshold that will actually matter sits around 15%, where a third player becomes unavoidable in comparisons and default integrations.

What this ranking does not measure
The methodological limit is stated openly and it weighs heavily. The panel covers web traffic, meaning visits to websites. Mobile applications are not counted, on iOS or on Android.
That gap hits Google hardest. A large share of Gemini interactions happens through direct app opens or through entry points wired into Android itself, outside any browser. A web-only reading structurally understates real usage of Google’s assistant. The same applies to any assistant reached through a system-level shortcut, a keyboard integration or a voice trigger, none of which register as a site visit. What the panel captures well is the deliberate act of opening an interface to work in it, which is a narrower behaviour than daily assistant usage.
The bias cuts against OpenAI too, whose mobile apps and desktop client escape the same count. The comparison stays useful because it is consistent from quarter to quarter, not because it captures total usage.
For teams building on these platforms, the practical takeaway is to stop treating this board as market share. It is a web traffic indicator, useful for reading an awareness and acquisition trend, useless for sizing an integration or justifying a technical choice.
A second caution applies to reading the swings. One isolated quarter is not a trend, especially on a panel counting visits rather than active sessions or time spent. Two consecutive readings pointing the same way are worth more than a single dramatic turn, and that is exactly what the next quarter will settle.
The next reading will show which of the two moves was the anomaly. Either the ChatGPT traffic share recovery closes a curiosity cycle for alternatives, or it reflects a seasonal bump and the yearly slope resumes next quarter.
