What could move it
- Any escalation in military activity or direct engagement between NATO and Russian forces would likely push odds higher; conversely, diplomatic developments or de-escalation could drive them lower.
- The resolution hinges on a specific definition of 'military encounter' involving use of force—ambiguous or borderline incidents near the deadline may create resolution uncertainty.
- With roughly two years until the December 2026 deadline, significant time remains for new geopolitical shocks to materially shift the odds.
