Will US withdraw from NATO before 2027?
🗂 Part of event: Will US withdraw from NATO by...? →💡 What the odds say
The market puts this at about a 3% chance — almost no chance.
No money — just record your call and see if you were right. Yes is at 3% right now.
The market sees a US withdrawal from NATO before 2027 as highly unlikely (3% Yes), despite ongoing political tensions and public discussions about a managed exit, because no formal denunciation has been initiated and alliance officials publicly downplay the risk.
📊 Base rate: Since NATO's founding in 1949, no member state has ever formally withdrawn under Article 13, making the historical base rate for any withdrawal essentially 0%.
What's driving it
- • A July 2026 news article from the Independent Institute explicitly argues for a managed US exit, keeping the idea in public discourse but not reflecting official action (Independent Institute, Jul 17).
- • In early July 2026, Trump reportedly mused about cutting US troops in Europe by a third to pressure NATO, signaling ongoing friction but stopping short of withdrawal (CNN, Jul 7).
- • Reuters reported in late June 2026 that Turkey stated NATO is adjusting to the security landscape and the US is not withdrawing, reinforcing the status quo (Reuters, Jun 30).
- • A June 2026 DW article captured the contrast: the US lashes out rhetorically while the NATO Secretary General insists everything is fine, suggesting no imminent break (DW.com, Jun 18).
The case for YES
- • A formal notice of denunciation under Article 13 could be submitted at any time by the President without congressional approval, and the market's resolution criteria count even a notice that is later halted by judicial action.
- • The Independent Institute's July 2026 article advocating a managed exit indicates that influential policy voices are preparing the intellectual groundwork for withdrawal (Independent Institute, Jul 17).
- • Trump's reported consideration of a one-third troop cut in Europe (CNN, Jul 7) shows a willingness to escalate pressure on allies, which could culminate in a formal withdrawal notice if demands are not met.
The case for NO
- • Reuters reported in June 2026 that Turkey, a key NATO member, explicitly stated the US is not withdrawing, reflecting insider knowledge of alliance stability (Reuters, Jun 30).
- • The Council on Foreign Relations noted at the June 2026 NATO Summit that Europe faces an accelerating US decoupling, but decoupling is not withdrawal—it is a gradual process that does not trigger the market's resolution (Council on Foreign Relations, Jun 30).
- • No official US government statement or legislative bill has proposed initiating a withdrawal, and the 3% odds imply the market sees such a dramatic step as extremely unlikely within the remaining 18 months.
What to watch
- • The US presidential election in November 2026: if a candidate openly advocating NATO withdrawal wins, odds could spike toward Yes; if a pro-NATO candidate wins, odds would drop further toward No.
- • Any official statement from the US State Department or White House about reviewing NATO commitments would push odds up, while a reaffirmation of Article 5 commitments would push them down.
- • A NATO summit or emergency meeting before year-end 2026 where the US makes concrete demands or threats could increase Yes odds if it signals an ultimatum.

Resolution criteria
This market will resolve to "Yes" if the United States formally initiates a withdrawal from NATO or provides an official notice of denunciation to NATO by December 31, 2026, 11:59 PM ET. Otherwise, this market will resolve to "No". A notice of denunciation refers to the submission of a notice of withdrawal as per Article 13 of the North Atlantic Treaty. Any action meeting these criteria will qualify for a “Yes” resolution regardless of if its implementation is immediately halted or delayed by judicial or other actions. The U.S.'s exit from NATO’s integrated military command structure will not be sufficient to resolve this market to "Yes". The resolution source will be official information from the US government and NATO, however a consensus of credible reporting may also be used.
ⓘ A market settles under its own written rules, which can lag what looks decided in the news — so the price may not move to 100% the moment an outcome seems obvious.
