Frequently asked questions

Does AI share differ between the world and Japan?
Yes. In market share for Jun 2026, ChatGPT stands out worldwide at about 78%, while in Japan Gemini holds a higher share than the world average, reaching double digits (source: StatCounter).
How often is the AI share data updated?
Every month we save StatCounter's public data as a monthly snapshot and update the history, month-over-month change and fastest risers/fallers. Each month's report is kept as an archive.
Are “market share” and “usage” the same?
Not exactly. Here, market share is a metric based on web-referral traffic via AI chatbots and does not fully represent usage across all users. Rankings change with the measurement method.
