Resolution criteria on PolyGram: 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.
PolyGram is an on-chain prediction market where you trade YES or NO outcome shares with real USDC on Polygon. For this market, buy YES if you believe the event will happen, or NO if you think it won't. Your maximum loss is your stake — winning shares pay $1.00 each at resolution. Unlike sportsbooks, there is no house edge: prices are set by supply and demand from other traders and reflect the crowd's real-time probability.
Market outcomes
| December 31, 2025 | 0% YES | 100% NO |
| June 30, 2026 | 1% YES | 99% NO |
| December 31, 2026 | 7% YES | 94% NO |
NATO membership withdrawal or formal denunciation notice by any member state before 31 December 2025 remains an extraordinarily low-probability event, reflected in the 0% implied probability on Polymarket's order book. The threshold for resolution is strict: a country must either formally withdraw or submit an official notice of denunciation under Article 13 of the North Atlantic Treaty. Merely exiting NATO's integrated military command structure—as France did in 1966, later rejoining in 2009—would not trigger a "Yes" resolution. The current market pricing suggests traders assess the institutional and political barriers to withdrawal as near-absolute within this timeframe.
Historical precedent offers limited guidance. No NATO member has ever formally withdrawn since the alliance's founding in 1949. France's temporary departure from integrated command was a political gesture that stopped short of treaty denunciation. Hungary and Poland have experienced severe tensions with NATO leadership over judicial independence and democratic standards, yet neither has signalled withdrawal intent. Turkey has periodically threatened to leave over Kurdish policy and arms embargoes, but these threats have not materialised into formal notice.
The primary catalyst traders should monitor is any formal announcement from a member government regarding withdrawal procedures or denunciation notices. Recent rhetoric from certain political figures regarding NATO burden-sharing and defence spending has intensified, particularly following the 2024 US election cycle. However, the distinction between political posturing and actionable legal steps remains significant. Any credible news reporting a government's submission of denunciation notice to NATO's Secretary-General would represent the decisive trigger for market movement.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "Will any country leave NATO by 2025?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$1.1M in lifetime turnover and $53K of resting liquidity puts this market in the top 2% by volume for world contracts on PolyGram. Order-book depth is strong — order books support five-figure trades with single-cent slippage.
Last 24 hours alone saw $1K in turnover, consistent with the market's lifetime daily-average pace.
The market has been open for 16 months — long enough that the order book is mature and price is well-anchored to fundamentals.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a 2-hour dispute window opens, and if uncontested the payout is final. Contested outcomes escalate to UMA token holders.
This prediction market is scheduled to close on 31 December 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
