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 April 30, 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.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.

The resolution source will be official information from the US government and NATO, however a consensus of credible reporting may also be used.President Trump has recently weighed a U.S. withdrawal from NATO following allies' refusal to assist in operations related to the Strait of Hormuz and Greenland amid the Iran conflict, with White House Press Secretary Karoline Leavitt confirming on April 8, 2026, that such a move would require congressional approval. A 2024 National Defense Authorization Act provision mandates a two-thirds Senate supermajority or legislative action to terminate membership, presenting significant institutional barriers despite NATO's Article 13 allowing one-year notice. No formal withdrawal process has begun, and upcoming talks between Trump and NATO Secretary General Mark Rutte could clarify alliance commitments, while public polls show majority U.S. support for continued membership. Traders assess low near-term probability given legal hurdles and bipartisan congressional opposition.
