Will the US take control of any part of Greenland?
I գնահատimate a low-single-digit to high-single-digit chance that the United States formally acquires control of any part of Greenland before 2029. The political and legal barriers are enormous, but the phrasing is broad enough that a narrow security or basing arrangement makes this possible in a very small tail scenario.
Analysis
A formal US acquisition of any part of Greenland would require Denmark and likely Greenlandic authorities to agree to a transfer, lease, or sovereignty change, and there is no visible structural path to that outcome. Greenland has strong local autonomy, Danish constitutional constraints are significant, and any sale or cession of territory would face intense domestic, European, and geopolitical resistance. The most plausible route is not annexation but a limited basing, access, or long-term security arrangement, which may not qualify as taking control under most market interpretations unless the wording is read very broadly.
The strongest argument for Yes is that the market question is unusually permissive. If the United States were to secure a long-term lease, exclusive control of a port, airfield, mineral site, or another small territory under a bilateral security deal, some forecasters might count that as acquiring part of Greenland. Trump-era rhetoric also keeps the tail alive because it can create negotiation pressure or unconventional deal-making attempts, even if the baseline probability remains tiny. That said, the absence of any concrete diplomatic process makes the event far from likely.
Compared with the current market price of 22% Yes, I think the market looks materially too high. A 22% price implies this is close to a one-in-four event, but the real-world constraints make it much closer to a long shot. The most likely reason for the elevated price is that traders are overweighting headline risk, ambiguous wording, and the possibility of a narrow technical interpretation of 'control,' rather than the far harder hurdle of actual territorial acquisition.
Arguments
For
- The question is broader than outright annexation, so a lease, exclusive base, or special jurisdiction agreement could count as success.
- Trump-era unconventional diplomacy and Greenland’s strategic value keep a small but real tail risk alive.
Against
- Denmark and Greenland would almost certainly resist any sovereignty transfer or territorial sale.
- There is no known negotiation track, legal framework, or public momentum toward US acquisition of Greenlandic territory.
Key drivers
- Any true transfer of Greenlandic territory would require extraordinary political agreement from Denmark and Greenland.
- The market wording is broad enough that a narrow lease or exclusive control arrangement could potentially satisfy some interpretations.
Risk factors
- A geopolitical crisis or security deal could produce an unexpected US foothold that a market adjudicator counts as control.
- Ambiguity over what counts as 'any part' could turn a limited base or lease into a Yes resolution.
Scenarios
Best case
The US secures a long-term agreement for exclusive control over a strategically important parcel, base, or port in Greenland, and the market resolves it as an acquisition of part of Greenland.
Most likely
The US continues to seek cooperation and expanded basing or security access, but no arrangement rises to the level of acquiring any part of Greenland.
Worst case
No transfer, lease, or exclusive territorial control is established, and Greenland remains entirely under Danish sovereignty and Greenlandic self-rule.

Will the U.S. invade Iran before 2027?
AI84%MKT14%Edge+70Hidden GemThe market looks substantially more likely to resolve Yes than the current price suggests because the reporting already describes U.S. military action in Iran in 2026, and the war is still active with no durable settlement. The main uncertainty is definitional, since a strict ground-control invasion is harder to confirm than strikes and wider offensive operations.

AI66%MKT11%Edge+55Hidden GemI think Starbucks is materially more likely than not to report more than 41,800 global stores in 2026. The market appears to be pricing in a slowdown that is possible, but the threshold is low enough relative to Starbucks’ historical footprint growth that Yes should be favored.
