Traders assign a 95.5% probability against NATO invoking Article 5 before 2027, reflecting sustained absence of armed attacks on alliance territory despite active conflicts in Ukraine and related tensions. Recent diplomatic channels, alliance force posture adjustments on the eastern flank, and restraint by key actors have prevented direct spillover into member states. Historical precedent shows Article 5 activation only once in response to a clear external assault, underscoring high thresholds. Scenarios that could still alter outcomes include escalation involving NATO border incursions or proxy actions triggering collective defense obligations within the resolution window.
