AI の回答 301025 件のデータ調査:ChatGPT、Gemini、Perplexity、Claude、Grok が Microsoft をどのくらいの頻度で引用しているかを、13 か月にわたって月ごとに分析しました。

Microsoft is cited in 1.03% of measured answers over the last three months, which places it seventh of the platforms tracked. It is cited by all five models, most often by Gemini at 1.89% and least often by Grok at 0.09%.
Microsoft properties are cited mostly as documentation, which is why the rate concentrates in cybersecurity and consulting.
A citation rate of 2% means the source was cited twice for every 100 measured answers. Rates are computed per model against the number of answers of that model, so a model with a smaller sample never distorts a column. A source cited several times inside one answer is counted once per company block, which keeps a single verbose answer from dominating a month.
The gap between the model that cites Microsoft most and the one that cites it least is 1.8 points. That spread, not the average, is what should decide a budget: the same work returns most on Gemini and least on Grok. Across all tracked platforms, Microsoft ranks seventh.
Over the 13 months measured, Microsoft moved from 0.72% in August 2025 to 0.87% in August 2026, with a peak of 2.19% in October 2025. Averaged over the first three months against the last three, the movement is minus 0.6 points.
This is a documentation effect rather than a brand effect. When a question touches software, security or workplace tooling, the models reach for vendor documentation, and Microsoft has the largest documentation surface in that space. The practical lesson generalises: in technical markets, documentation is the format the models cite, and most companies publish marketing pages where documentation would earn the slot. Writing the reference page you keep postponing is the closest thing to a repeatable tactic this dataset offers.
