- Will US withdraw from NATO before 2027?3¢
- Will US withdraw from NATO by August 31?<1¢
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.
Legal and procedural barriers continue to constrain prospects for formal U.S. withdrawal from NATO. A 2023 statute, signed into law by President Biden and co-sponsored by then-Senator Marco Rubio, requires either a two-thirds Senate vote or separate congressional authorization before any president can terminate the treaty. The Trump administration has accelerated force posture reviews, announced reductions in U.S. troops and capabilities assigned to NATO plans, and shifted leadership of certain commands to European allies, yet no notification process or Senate debate on exit has begun. European members have committed to filling gaps in the NATO Force Model ahead of upcoming summits, while congressional leaders across parties have signaled opposition to unilateral action. These dynamics keep trader attention on incremental burden-sharing adjustments rather than outright alliance termination.
