In brief
Polymarket's prediction market assigns only a 6.5% probability to the US acquiring any part of Greenland by December 31, 2026. Recent deployment of Danish conscripts to Greenland and firm opposition from Copenhagen and Nuuk make a binding agreement or transfer of sovereignty highly improbable this year.
Introduction
President Donald Trump's repeated calls for the US to acquire Greenland have reignited geopolitical tensions in the Arctic. While the idea has been floated since 2019, the 2026 deadline for a potential acquisition now appears increasingly unrealistic. Polymarket bettors are heavily favoring the 'No' outcome, and recent developments on the ground reinforce that view.
What to know
On September 2, 2026, Reuters reported that Denmark has sent conscripts to Greenland for the first time in recent history, signaling a boost to Arctic defenses amid US demands. The South China Morning Post confirmed the deployment, noting that Trump has repeatedly sought to acquire the semi-autonomous Danish territory, citing national security concerns. Both Denmark and Greenland have firmly rejected any transfer of sovereignty. The market's resolution criteria require a binding agreement or legal instrument—such as a treaty, legislation, or executive action—that unambiguously transfers sovereignty or establishes exclusive US jurisdiction. Non-binding statements, negotiations, or leases do not qualify. As of September 2026, no such instrument exists, and the conscript deployment underscores Denmark's commitment to maintaining control.

The factors at play
- Danish military reinforcement: The conscript deployment to Greenland signals a clear intention to defend the territory, reducing the likelihood of a voluntary transfer.
- Political opposition: Both Denmark and Greenland's governments have publicly rejected any US acquisition, making a negotiated deal politically toxic.
- Legal hurdles: Any transfer would require complex treaty negotiations, likely years in the making—not achievable by end of 2026.
- US domestic politics: With Trump still in office, the push continues, but without concrete legislative or executive action, the market sees little chance.
- Use of force: While the market would resolve 'Yes' if the US used force to gain control, such a scenario is extremely unlikely given NATO alliances and international law.
Our prediction
According to our analysis, the most likely outcome is No. Polymarket currently assigns a probability of 93.5% to No, while our internal estimate is 96%. The slight difference stems from the recent conscript deployment, which further solidifies Denmark's position and reduces any residual chance of a surprise deal. We see no credible path to a binding agreement by December 31, 2026.
Risks and uncertainties
- Unexpected diplomatic breakthrough: A last-minute treaty or executive agreement cannot be entirely ruled out, though it would require a dramatic reversal from Denmark and Greenland.
- Escalation of US pressure: Trump could impose economic sanctions or other coercive measures, potentially forcing negotiations.
- Change in Greenlandic leadership: A pro-US independence movement could theoretically negotiate a separate deal, but no such movement currently holds power.
- Military incident: A conflict in the Arctic could lead to a US takeover, but this remains a low-probability tail risk.
Conclusion
The Polymarket odds reflect a realistic assessment: the US acquiring part of Greenland in 2026 is a long shot. Denmark's conscript deployment is the latest sign that the status quo will hold. Unless a dramatic geopolitical shift occurs, the 'No' outcome is virtually certain.
