Kalshi's longer-dated contract (before January 21, 2029) prices in 23%, which is structurally higher simply because it spans Trump's full second term rather than just the next few months, giving diplomacy or a "framework of a future deal" floated after Trump's Davos meeting with NATO's Rutke more time to materialize.

Descriptions normalized for comparison (outcome names replaced with [OUTCOME]) Highlight differences 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.

Kalshi

If the United States acquires any part of Greenland before Jan 21, 2029, then the market resolves to Yes.

Additional Settlement Rules An announcement by the United States and the entity that controls any part of Greenland that it will happen is also encompassed by the Payout Criterion. any part of Greenland must come under formal governance or jurisdiction of the United States, either as a state, territory, or other classification within the US system, where it was not previously. Merely leasing a given part in territory – for example, setting up a military base on leased territory – is not encompassed by the Payout Criterion.
