How it resolves

The rules, word for word as Polymarket publishes them:

This market will resolve to "Yes" if there is a military encounter between the military forces of a NATO country and Russia between September 23 and December 31, 2025, 11:59 PM ET. Otherwise, this market will resolve to "No". A "military encounter" is defined as any incident involving the use of force such as missile strikes, artillery fire, exchange of gunfire, or other forms of direct military engagement between NATO and Russian military forces. Non-violent actions, such as airspace violations, firing of warning shots (such as the June, 2021 Black Sea Confrontations between Russian forces and HMS Defender), or cyberattacks will not qualify. Interception of missiles or other one-way attack or loitering munitions (e.g. Shahed drones) which are targeting a 3rd party other than the listed countries or their respective forces will not alone qualify. Shooting down UAVs which are not munitions (e.g. MQ-9, Orlan 10, Orion, Bayraktar TB2, etc.) will qualify. Intentional physical collisions, including aerial interceptions and naval ramming without the direct use of weaponry, such as the 2023 Black Sea incident—where a Russian Su-27 damaged a U.S. MQ-9 Reaper drone's propeller, leading to its crash— will not qualify regardless of damage. Military contractors will qualify only if confirmed to be operating under the direct command or coordination of the respective state’s armed forces (e.g. the Battle of Khasham would not qualify). The resolution source for this market will be a consensus of credible reporting.

How results are settled:
Polymarket markets are typically settled through UMA's optimistic oracle: a result is proposed after the event, can be disputed during a challenge window, and is final once undisputed or decided.

How to read these odds

A share of each outcome costs its chance in cents and pays $1 if it happens, so 15% means about 15¢ a share and roughly 6.9x back if right. On a ladder of dates or levels each rung is its own yes/no market, so the prices don't add up to 100%. Guides: reading Polymarket odds, odds to probability, glossary.
