Will the US take control of any part of Canada?
The chance of the United States acquiring any part of Canada before 2029 is extremely low. Even allowing for political volatility and rhetoric, a territorial transfer would require an extraordinary collapse in Canadian sovereignty and would face overwhelming legal, diplomatic, and military barriers.
Analysis
My independent estimate is that this resolves Yes at about 2%. The key reason is that “take control of any part of Canada” implies an actual change in sovereignty or effective control, not just heated rhetoric, trade pressure, or symbolic disputes. For this to happen, Canada would need to voluntarily cede territory, suffer an unprecedented internal breakdown, or face some form of coercive occupation or treaty settlement, all of which are extraordinarily remote within the remaining timeframe.
The strongest argument for Yes is that U.S.-Canada relations are asymmetric, and a highly disruptive political environment could in theory create unusual leverage over a small or strategically important area, especially if domestic instability in Canada were severe. But even that is a stretch: Canada is a stable allied democracy, deeply integrated with the United States yet strongly resistant to any sovereignty loss, and any attempt by Washington to assert control would trigger immediate Canadian, legal, NATO-adjacent, and global backlash. There is also no plausible mainstream policy path under which an American administration could absorb part of Canada without causing a major constitutional and international crisis.
The market’s 9.9% Yes price looks materially too high for the actual territorial-control question. Some of that may reflect traders loosely pricing in provocations, tariffs, border disputes, or headline-grabbing rhetoric rather than a real acquisition event. Those scenarios can be noisy and politically salient, but they are not close substitutes for the United States acquiring Canadian territory, which remains a near-tail event.
Arguments
For
- A small, strategically important area could theoretically change hands under extraordinary circumstances such as a treaty, referendum, or state collapse.
- U.S.-Canada dependence creates some geopolitical leverage, which can lead traders to assign a nonzero probability to extreme outcomes.
Against
- Canada is a stable sovereign state with strong institutions, making territorial loss to the United States extraordinarily unlikely.
- Any U.S. attempt to seize or control Canadian territory would provoke overwhelming domestic and international opposition.
Key drivers
- Any actual transfer of Canadian territory would require exceptional legal and diplomatic conditions that are not presently visible.
- Political rhetoric or trade conflict could raise perceived odds, but it does not meaningfully translate into sovereignty change.
Risk factors
- A severe Canadian constitutional crisis or regional secession movement could create a narrow path to some form of U.S. control.
- The market may be interpreting ambiguous future events as satisfying the question even if they fall short of true territorial acquisition.
Scenarios
Best case
A narrow territorial or administrative transfer occurs through an extraordinary but peaceful political process, such as a local referendum followed by an unusual bilateral agreement.
Most likely
The United States and Canada remain territorially unchanged, with occasional political friction that never approaches actual acquisition or control.
Worst case
No part of Canada changes hands, and the period is limited to rhetorical conflict, trade disputes, or isolated border tensions.

How many Fed rate cuts in 2026?
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.
