Will the US take control of any part of Greenland?
A U.S. acquisition of any part of Greenland before 2029 is possible only in a very loose, exceptional sense, and a formal territorial transfer looks highly unlikely. My independent estimate is well below the market price, because the political, legal, and diplomatic barriers are enormous.
Analysis
The core issue is what “take control” means in practice. If the market settles for a narrow interpretation such as a long-term base expansion, special security zone, or some form of U.S. administrative control negotiated with Denmark and Greenland, the odds are not literally zero. But if the question implies the United States actually acquires sovereignty over any part of Greenland, that would require an extraordinary political agreement among Denmark, Greenlandic leaders, and the United States, plus likely broad public support in Greenland and Denmark. That is a very high bar, and there is no structural momentum pointing toward it today.
The strongest argument for Yes is that Greenland has persistent strategic value for the United States, especially for Arctic defense, missile warning, and competition with Russia and China. A more assertive Trump administration could try to force negotiations or seek some unusual arrangement that looks like control even if it falls short of outright annexation. Still, prior interest in Greenland has not translated into a credible path to territorial transfer, and the practical obstacles are steep: Denmark is a NATO ally, Greenland has its own political identity and self-government, and any transfer of territory would be diplomatically explosive.
Compared with the current market price of 25%, the market appears too optimistic on a genuine acquisition outcome. The most likely resolution is that no part of Greenland is formally acquired by the United States before 2029, even if rhetoric, military cooperation, or investment interest intensify. The market may be pricing in a vague loophole around leases or control arrangements, but absent very specific wording in the contract, the base rate for actual U.S. acquisition is low.
Arguments
For
- The U.S. has strong strategic reasons to seek greater presence in Greenland, which could create pressure for an unusual arrangement.
- If the contract defines “control” broadly, a lease, exclusive-use zone, or similar concession could qualify.
Against
- Greenlandic and Danish political resistance makes a genuine transfer of territory extremely unlikely.
- There is no clear near-term pathway from strategic interest to legal acquisition of territory.
Key drivers
- Formal territorial acquisition would require unprecedented agreement from Denmark and Greenland.
- Strategic interest in the Arctic could produce cooperation short of sovereignty transfer.
Risk factors
- The market may interpret a security lease or base expansion as “control,” even without annexation.
- A Trump administration could pursue unusual diplomatic pressure that raises the chance of an outlier arrangement.
Scenarios
Best case
The United States negotiates a highly unusual arrangement that grants it exclusive control over a small area for military or strategic purposes, and the market treats that as a Yes.
Most likely
The U.S. increases rhetoric and strategic engagement around Greenland, but no formal acquisition or comparable control arrangement occurs before 2029.
Worst case
No part of Greenland changes sovereignty or control, and the U.S. relationship remains limited to cooperation and existing military access.

AI11%MKT93%Edge-82HypedI think there is still a meaningful chance of at least one Fed cut in 2026, but the market is pricing in a very strong hold case for a reason. My estimate is that there is about an 11% chance of no rate cuts at all in 2026.

How many more Millennium Prize Problems will AI solve in 2026?
AI88%MKT19%Edge+69Hidden GemI think there is a strong chance that no qualifying Millennium Prize Problems will be counted for 2026 under this market’s rules, even though OpenAI’s Navier-Stokes claim makes the broader “AI solved a Millennium Problem” narrative look more plausible. The exclusion of Navier-Stokes from resolution is the key reason the zero-solved outcome still looks likelier than not.

Will OpenAI or Anthropic IPO first?
AI34%MKT95%Edge-61HypedMy independent view is that OpenAI is less likely than the market implies to be the first of the two to IPO. The current reporting tilt favors Anthropic moving earlier, and OpenAI’s process appears more valuation- and timing-constrained.
