Russia x Ukraine ceasefire in 2025?

This market will resolve to "Yes" if there is an official ceasefire agreement, defined as a publicly announced and mutually agreed halt in military engagement, between Russia and Ukraine by December 31, 2025, 11:59 PM ET. If the agreement is officially reached before the resolution date, this market will resolve to "Yes," regardless of whether the ceasefire officially starts afterward. Any form of informal agreement will not be considered an official ceasefire. Humanitarian pauses will not count toward the resolution of this market. This market's resolution will be based on official announcements from both Russia and Ukraine; however, a wide consensus of credible media reporting stating an official ceasefire agreement between Russia and Ukraine has been reached will suffice.

How trading works

Polymarket uses a central limit order book (CLOB) model — you can buy or sell shares of any outcome at the current market price, or place limit orders at your target price. All positions are settled in USDC when the market resolves.

Resolution

Markets resolve through UMA's Optimistic Oracle. After the market closes, a proposer submits a resolution, followed by a 2-hour dispute window. If no dispute is raised, the resolution is accepted. Disputed markets go to UMA token holder vote.
