A direct military clash between NATO and Russia remains a tail risk that markets are attempting to price. The contract asking whether such an encounter will occur by December 31, 2026 trades at 23.5%, placing it in a substantial minority view territory. This means that while a clash is not the baseline assumption, the probability is high enough to be taken seriously. The market’s resolution rules are specific: it will settle to 'Yes' if a military encounter occurs between September 23 and December 31, 2025, 11:59 PM ET, involving the use of force such as missile strikes, artillery fire, or exchanges of gunfire. The definition explicitly excludes non-violent incidents like airspace violations, warning shots, or cyberattacks. Interceptions of one-way attack drones targeting third parties do not count, though shooting down non-munition UAVs, such as surveillance drones, would qualify. Intentional physical collisions, even if they cause damage—like the 2023 Black Sea incident where a Russian jet damaged a US drone—are also excluded. Military contractors are only covered if under direct state command. Volume has reached $6.4M. These fluctuations suggest continued reassessment of the risk, though it remains a minority view.
