Will any country leave NATO by December 31, 2026? Odds: 12.0% YES on Polymarket. See live prices and trade this market.
The market pricing NATO exit at 12% reflects sustained political tensions within the alliance but maintains that departure remains unlikely, a question gaining urgency as the 2024 U.S. presidential election approaches and Donald Trump leads Republican primary polls while openly questioning America’s NATO commitment.

Market Analysis
The bull case centers on Trump’s potential return to the White House in January 2025, giving him nearly two years to execute NATO withdrawal before the market closes. Trump previously explored Article 13 withdrawal during his first term, and his recent statements suggest even stronger skepticism toward collective defense obligations. Turkey presents another exit vector—President Erdogan has threatened withdrawal multiple times over Syria policy disagreements and arms embargoes, while cultivating closer ties with Russia. Hungary under Viktor Orbán represents a third possibility, as Budapest has blocked aid to Ukraine and maintained warm relations with Moscow, creating friction that could escalate to formal departure. The one-year notice period required under Article 13 means any country triggering withdrawal by December 31, 2025 would satisfy market conditions.
The bear case emphasizes the massive institutional inertia preventing NATO exit. Congressional Republicans passed legislation in 2023 requiring Senate approval for U.S. withdrawal, creating a legal obstacle even under Trump. Turkey, despite repeated threats, benefits enormously from NATO membership through military aid, intelligence sharing, and protection of its Article 5 guarantee—actual departure would leave Ankara strategically isolated. Economic and security costs of exit are prohibitive for any member state. Historical precedent strongly favors stability: no country has ever invoked Article 13 in NATO’s 75-year history, and even France’s 1966 withdrawal from military command kept it within the political alliance.
Key catalysts include the November 2024 U.S. presidential election outcome, Trump’s potential January 2025 inauguration, and Turkey’s May 2028 presidential election—though Erdogan could act sooner if tensions over Sweden’s completed NATO accession or F-16 sales flare again. Watch for any formal Article 13 notification, which requires one year’s written notice to the U.S. State Department. NATO’s 75th anniversary summit in July 2024 and the 2025 summit could produce confrontations triggering withdrawal discussions. The critical deadline is actually December 31, 2025, when any departing nation must submit notice to meet the market’s end date.

Frequently Asked Questions
Would a U.S. withdrawal from NATO’s military command structure without full Article 13 withdrawal resolve this market as YES?
No, the market specifically asks about countries leaving NATO entirely. Partial withdrawal from command structures, as France did from 1966-2009 while remaining a political member, would not trigger a YES resolution.
If a country formally announces withdrawal in late 2026 but the one-year notice period extends past the December 31, 2026 deadline, does that count?
This depends on exact market resolution criteria, but typically the notification date rather than effective exit date would matter. Traders should verify whether “leave” means filing Article 13 notice or completing the full withdrawal process.
Could Trump withdraw the U.S. from NATO through executive action despite the 2023 law requiring Senate approval?
Trump could attempt executive withdrawal claiming commander-in-chief authority, triggering a constitutional crisis and likely Supreme Court case, though such action would face immediate legal challenges and the process would extend well into 2025 or beyond.
