NATO's institutional framework, treaty obligations, and recent summits have sustained alliance cohesion despite U.S. force reviews and calls for greater European burden-sharing under the NATO 3.0 concept. As of October 2026, the Ankara summit communiqué reaffirmed Article 5 commitments, while Secretary General Mark Rutte emphasized rebalancing toward a stronger European pillar within the existing structure, supported by rising allied defense investments and ongoing coordination against Russian hybrid threats. Traders assign 98.6% probability to no dissolution before 2027 because formal exit requires congressional approval and lacks momentum, with adjustments focused on troop posture rather than treaty termination. Unlikely triggers that could still shift odds include abrupt U.S. legislative changes or a severe transatlantic crisis over conflict escalation before the end of 2026.
