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.

A prediction market is a real-money contract that pays $1 per YES share if the stated outcome occurs, and $0 if it does not. The current price is therefore the crowd's probability estimate — set by thousands of traders competing in a live order book, not a bookmaker. PolyGram routes your order into the same Polymarket venue, adds an email-first login and USDC deposits, and settles on Polygon within minutes of the result.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
