New market signals suggest Google’s Gemini is under pressure in the AI market, with ChatGPT and Claude appearing to gain relative strength. The picture is not based on one perfect measurement. It comes from three different data points, each with its own limits, but all pointing toward weaker Gemini usage.
What the new market data says
The clearest shift comes from AI text recognition platform Pangram, which analyzed model market shares based on submitted texts. In that dataset, the leading provider has held over 50 percent every month since tracking began, while Anthropic moved from 4.3 to 14.9 percent.
Pangram’s data also shows a sharp decline for Gemini. According to the source article, Gemini fell from 12 percent to just 1.9 percent in July 2026. Pangram described that drop as a "collapse."
The gains for Anthropic were mainly seen in technical and scientific fields. That matters because those are areas where model choice can be especially deliberate: users often select tools based on whether the output is useful for complex writing, reasoning or domain-heavy work.
Why Gemini’s decline is difficult to dismiss
No single dataset can fully capture AI usage. Pangram mostly reflects writing tasks, and the source notes that Gemini has always trailed Claude and ChatGPT in that area. That means Pangram should not be treated as a complete map of the AI market.
But Pangram is not the only signal. The source article also says OpenRouter data reflects a similar movement. OpenRouter has its own blind spot, because it skews toward open-weight models, but its direction still lines up with Pangram’s findings.
Similarweb adds a third view. Its data shows Google’s website market share dipped last month from 27 to 26.8 percent. That decline is small on its own, and the same source says the figure was just 9.4 percent a year ago, so the broader website trend still looks much stronger than it did then.
Even so, when three sources with different weaknesses point toward softer Gemini usage, the pattern becomes harder to ignore. The issue is not that any one dataset is definitive. The issue is that the combined picture is consistent.
The measurement problem
AI market share is hard to measure cleanly because people reach these systems through many different channels. Some users visit websites. Others use mobile apps. Some access models through routing platforms, and others submit generated text to services that detect or classify AI output.
The source article highlights those limitations directly:
- Pangram mostly measures submitted texts, especially writing-related use cases.
- OpenRouter skews toward open-weight models.
- Similarweb does not include mobile apps.
- Google claims one billion monthly Gemini App users, but monthly active users is described as a very low-quality signal.
That last point is important. A large monthly user number can show reach, but it does not necessarily reveal intensity, loyalty or whether users prefer one model over another for serious tasks. A person can count as active without making a product central to their workflow.
By contrast, usage patterns in submitted texts or model routing can reveal where people are turning when they need a system to produce work. Those signals are also incomplete, but they can expose preference shifts that broad user counts may hide.
What this means for Google
The source article connects the market data to a recent leadership shakeup at Google DeepMind, which saw several senior figures depart, including Demis Hassabis. It does not prove that market share pressure caused those departures. But it does suggest a possible explanation for why Google’s AI organization may be under strain.
For Google, the challenge is not simply visibility. The company says Gemini App has one billion monthly users. The harder question is whether those users are choosing Gemini when they have alternatives such as ChatGPT and Claude.
Pangram’s numbers suggest that, at least in the writing tasks it sees, Gemini has lost substantial ground. Anthropic’s rise from 4.3 to 14.9 percent shows Claude gaining traction, especially in technical and scientific fields. The leading ChatGPT-related share staying over 50 percent every month since tracking began shows continued strength at the top of the market.
Similarweb complicates the picture because Google’s website market share remains far above where it was a year ago. A dip from 27 to 26.8 percent last month is not the same as a broad collapse. But combined with the Pangram and OpenRouter signals, it supports the broader conclusion that Gemini’s momentum looks weaker than its headline app-user figure might suggest.
The bottom line
The available evidence is imperfect, but it is not random. Pangram, OpenRouter and Similarweb each view a different slice of AI usage. Each has blind spots. Yet all three indicate that Gemini is losing ground relative to key rivals.
The most striking figure remains Pangram’s July 2026 reading: Gemini down from 12 percent to 1.9 percent. In a market where ChatGPT continues to command more than 50 percent in Pangram’s tracking and Claude is rising, Google’s AI product faces a clear perception and usage challenge.
