Tier C — AI-reviewed by GPT-6 Luna, evidence as of 2026-10-19.
As of 2026-10-19 23:03 UTC — source: Polyscan AI review, n=1 for this pair
The review confirmed one divergence: “Any portion versus majority of territory”.
The phrase the review relied on most, one per venue: Kalshi: “purchases at least part of Greenland from Denmark” Polymarket: “transfer of the majority of the territory of Greenland”
Kalshi asks whether the US purchases at least part of Greenland; Polymarket asks whether the US officially announces sovereignty, defined as a transfer of most of the territory. A purchase of a small portion can therefore resolve Yes on Kalshi and No on Polymarket.

This market will resolve to "Yes" if the United States officially announces that Greenland will come under US sovereignty by December 31, 2026, 11:59 PM ET. Otherwise this market will resolve to "No". Sovereignty is defined as the transfer of the majority of the territory of Greenland from its current status as an autonomous territory within the Kingdom of Denmark to being under the formal governance or jurisdiction of the United States, either as a state, territory, or other classification within the US system. An official announcement made by the United States and Denmark that Greenland will come under US sovereignty will qualify, even if the actual transfer of sovereignty is yet to occur. Only announcements of official agreements or actions (e.g. executive order, signed legislation, etc.) will count - mere posts on Social Media will not. The resolution source for this market will be official information from the governments of the US, Greenland, and Denmark, however a consensus of credible reporting confirming that Greenland has come under U.S. sovereignty will also qualify.
