Context
The probability currently stands at 3.8%. The 24-hour change is -0.4 pts. The line has been relatively stable, with only minor fluctuations. The market resolves based on incidents between May 28 and May 29, 2027. A qualifying military encounter requires direct use of force—missile strikes, artillery fire, or exchange of gunfire. Non-violent actions like airspace violations, warning shots, and cyberattacks are excluded. Intentional physical collisions without weapons, such as the 2023 Black Sea drone incident, also do not count. Military contractors only count under direct state command. Resolution relies on a consensus of credible reporting. The odds could shift as the resolution deadline of May 29, 2027 approaches. Any credible reports of an armed engagement between US and Russian forces would directly affect the probability.
