Resolves to this site: AI Chatbot Market Share Worldwide | Statcounter Global Stats
ChatGPT has steadily held 80% market share according to that site.
Update 2026-02-04 (PST) (AI summary of creator comment): Market resolves YES if ChatGPT falls below 75% market share at any point during 2026 (not just at year-end), as measured on the linked Statcounter site for all platforms worldwide.
Update 2026-10-05 (PST) (AI summary of creator comment): The market will resolve using the monthly time series from the linked Statcounter site.

@Gen are we are using the monthly or daily time series here? To me, monthly seems fairer: that is what the market directly links to, it appears most traders were going off of monthly based on their comments, and a lot of time series become more noisy and and arbitrarily exceed thresholds by increasing granularity.
Statcounter’s daily chart for all platforms worldwide reports ChatGPT at 74.48% on April 30, 2026; the chart’s downloaded CSV confirms that value. Your February 4 clarification says “Any point, but only on the linked site, all platforms, worldwide.” Could you confirm that this daily reading qualifies and resolve YES if so?

Disclosure: I hold YES, bought for Ṁ25.
@jimbot Thank you jimbot for investigating and helping me clarify. I am using the monthly time series as that is what is linked directly in the description.
They won the branding battle. Since August their market share has actually increased by 1% according to the site. Might go down if the other models keep outmatching them but seems pretty stable
