This market will resolve to "Yes" if any member state formally withdraws from NATO or provides an official notice of denunciation to NATO by December 31, 2025, 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. A country's exit from NATO’s integrated military command structure will not be sufficient to resolve this market to "Yes". That country must either withdraw or submit a notice of denunciation to trigger a "Yes" resolution. The resolution source will be official information from the relevant government and NATO, however a consensus of credible reporting may also be used.

"context_description": "President Trump's recent threats to withdraw the United States from NATO, following allies' refusal to support US-led actions in the Strait of Hormuz amid escalating tensions with Iran, have fueled speculation and driven trader sentiment. European members including France, Italy, and Spain blocked US overflights and declined involvement, prompting Trump's public warnings of a \"very bad future\" for the alliance without greater burden-sharing. However, US law—including the 2024 National Defense Authorization Act—requires two-thirds Senate approval for exit, presenting major procedural hurdles under Article 13's one-year notice provision. No other NATO members have issued formal denunciations or shown intent to leave, with historical precedent showing no permanent withdrawals since Greece's 1974-1980 hiatus. Odds remain low as traders weigh rhetorical pressure against entrenched legal barriers and alliance inertia, absent imminent catalysts like congressional votes or diplomatic breakthroughs.",
