The question addresses whether the United States will formally withdraw from the North Atlantic Treaty Organization before April 30, 2026. NATO, established in 1949, has served as the primary collective defense alliance for North America and Europe. The current 1% probability reflects market participants' assessment that full US withdrawal within this timeframe is extremely unlikely, despite ongoing political debates about alliance structures and burden-sharing. The market is resolvable through official statements from US government authorities or NATO announcements regarding formal withdrawal procedures. Resolution would require explicit notification and completion of formal withdrawal protocols as outlined in NATO's founding treaties. The 1% odds suggest traders view the scenario as highly improbable but acknowledge non-zero geopolitical risk. Trading volume of $81,252 over 24 hours indicates moderate market interest in this outcome, with $176,805 in available liquidity supporting both bullish and bearish positions. The odds trajectory has remained near historical lows, reflecting consistent market consensus on the stability of US NATO membership through the resolution period.
