This market tracks whether the United States will acquire control of any land territory that is part of Greenland through a binding agreement or legal instrument establishing transfer of sovereignty or jurisdiction. Aggregating data from Polymarket and Opinion, the consensus probability stands at 11.5% for a US acquisition occurring by the end of 2026. Resolution will be determined by official information from the governments of the United States, Denmark, and Greenland, with credible reporting used as supporting consensus. Watch for any formal diplomatic announcements or signed agreements before the December 31, 2026 resolution deadline.

Unified Resolution Criteria (Consistent across platforms)
Both platforms employ identical resolution criteria, qualifying events, exclusions, and source hierarchy with no material divergence.Primary resolution logic: Official information from the governments of the United States, Denmark, and Greenland; consensus of credible reporting may also be used.Core resolution logic:
- Transfer of Sovereignty: A binding agreement or legal instrument must result in a defined area of Greenland coming under formal U.S. sovereignty (e.g., U.S. state, territory, possession, or other political classification), even if the effective date occurs after the market deadline.
- Acquisition of Primary or Exclusive Jurisdiction or Control: A binding agreement or legal instrument must establish a defined area in Greenland where the U.S. has primary or exclusive jurisdiction or control such that Denmark and Greenland's ordinary legal authority does not apply except by U.S. permission, even if the effective date occurs after the market deadline.
- Use of Force: The U.S. acquires primary or exclusive jurisdiction or control over a defined area of Greenland through military or coercive means.
- Binding Instrument Requirement: An announcement qualifies only if accompanied by or consisting of a binding agreement or legal instrument (enacted legislation, signed treaty, signed agreement text, or executive action implementing such agreement) that unambiguously creates the transfer or acquisition.
- Non-Qualifying Arrangements: Non-binding statements, negotiations, proposals, frameworks, MOUs, basing rights, access agreements, SOFA-type arrangements, COFA-type arrangements, commercial concessions, leases, or other permissions to use land do not qualify.
- Baseline Exclusion: Any qualifying U.S. jurisdiction or control in Greenland that existed at market creation does not count as new qualifying control.
Edge cases & clarifications:
- Effective Date After Deadline: A binding agreement or legal instrument signed, enacted, or executed by December 31, 2026, 11:59 PM ET qualifies even if the actual transfer or handover of territory or jurisdiction occurs after that deadline.
- Guantanamo-Style Arrangement: An exclusive or primary U.S. jurisdiction and control arrangement over a defined zone in Greenland where Denmark and Greenland's ordinary legal authority does not apply except by U.S. permission qualifies as acquisition of primary or exclusive jurisdiction or control.
- Partial Territory Acquisition: Acquisition of any portion or defined area of Greenland, not necessarily the entire island, satisfies the resolution criteria.
- Credible Reporting Consensus: If official government sources are unavailable or conflicting, a consensus of credible reporting from major news organizations and international bodies may be used as a secondary resolution source.
- Pre-Existing Arrangements: Any U.S. jurisdiction, control, or basing rights that existed prior to market creation are excluded and do not count toward resolution.
Polymarket
This market will resolve to “Yes” if the United States acquires control of any land territory that is part of Greenland by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to “No”. Only the transfer of sovereignty, or the acquisition of primary or exclusive jurisdiction or control qualifies. 1. Transfer of Sovereignty: This will qualify if a binding agreement or legal instrument results in a defined area of Greenland coming under the formal sovereignty of the U.S. (e.g., incorporated as a U.S. state, territory, possession, or other U.S. political classification), even if the effective date occurs after the market deadline. 2. Acquisition of Primary or Exclusive Jurisdiction or Control: This will qualify if a binding agreement or legal instrument establishes a defined area in Greenland in which the U.S. has primary or exclusive jurisdiction or control over the territory, such that the ordinary legal authority of Denmark and Greenland do not apply,except by U.S. permission. Such agreements or instruments will qualify even if the effective date occurs after the market deadline. 3. Use of Force: If the U.S. acquires primary or exclusive jurisdiction or control over a defined area of Greenland through force, this will also qualify. An announcement will qualify only if it is accompanied by or consists of a binding agreement or legal instrument (e.g., enacted legislation, a signed treaty, the signed text of an agreement, or an executive action implementing such an agreement) that unambiguously creates a transfer of sovereignty, or primary or exclusive jurisdiction or control, even if this transfer or acquisition takes effect after the market deadline. Non-binding statements, negotiations, proposals, frameworks, or MOUs will not alone qualify. Basing rights, access agreements, SOFA-type arrangements, COFA-type arrangements, commercial concessions, or other permissions to use land (including leases) will not alone qualify. Any qualifying U.S. jurisdiction or control in Greenland that existed at market creation will not count as new qualifying control. Examples of qualifying events include but are not limited to treaty or piece of legislation that makes any portion of Greenland a U.S. territory or possession, even if the handover date for such territory or possession is later); or, a Guantánamo-style arrangement establishing a defined zone in Greenland under exclusive or primary U.S. jurisdiction and control, where Denmark and Greenland’s ordinary legal authority does not apply except by U.S. permission. The primary resolution source for this market will be official information from the governments of the United States, Denmark, and Greenland; however, a consensus of credible reporting may also be used.

Frequently asked questions
Prediction markets like this one typically embed forward-looking expectations that differ from traditional polling. While polls measure current public opinion or expert sentiment at a snapshot in time, traders are pricing the actual probability of an acquisition occurring by year-end 2026. Markets incentivize accuracy through real money, so odds often reflect deeper analysis of diplomatic negotiations, political feasibility, and geopolitical leverage than surveys capture. Comparing this market's odds to any available expert forecasts or policy analysis can reveal whether traders are pricing in tail risks or consensus views that public discourse has not yet fully priced in.
Polymarket and Opinion can show different implied probabilities on the same event for several reasons. Polymarket and Opinion can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Differences in user base expertise, regional trader concentration, and liquidity availability mean each platform may weight the same news or geopolitical signals differently. Platform-specific fee structures and withdrawal policies also influence how aggressively traders commit capital. Additionally, timing lags in order-book updates or asymmetric information arrival across venues can create temporary spreads. These divergences are normal and often present arbitrage opportunities for traders monitoring both platforms simultaneously.
This market resolves around Dec 31, 2026, at which point the outcome is confirmed based on whether any portion of Greenland has been formally acquired by the United States. Resolution hinges on verifiable public reporting from credible sources documenting an actual territorial transfer or acquisition agreement. The bar is whether a measurable acquisition has occurred, not whether negotiations were attempted or proposals were made. Once the end date passes and reporting is finalized, the market settles according to the outcome.
Key catalysts include official statements from US or Greenlandic leadership regarding territorial negotiations, any formal acquisition proposals or agreements, changes in Danish or Greenlandic political leadership, geopolitical developments affecting Arctic strategy, and major media coverage of US interest in Greenland. Economic announcements about resource extraction or strategic infrastructure in Greenland could also shift trader conviction. Diplomatic meetings, congressional testimony, or leaked negotiation details would likely trigger sharp repricing. Closer to year-end, the absence of any acquisition announcement would gradually push odds lower, while any credible acquisition news would spike them higher.
