Will Russia capture Siversk by August 31?

This market will resolve to “Yes” if, according to the ISW map, Russia captures the Siversk railroad station located off of Zaliznychna Vulytsia by August 31, 2025 at 11:59 PM ET. The railroad station will be considered captured if any part of the train station icon is shaded red on the ISW map (https://storymaps.arcgis.com/stories/36a7f6a6f5a9448496de641cf64bd375) by the resolution date. If the area is not shaded red by August 31, 2025, 11:59 PM ET, the market will resolve to “No”. Once Russia captures the railroad station, any subsequent loss of control will not be considered towards the resolution of this market. If Russia comes into control of this territory as a result of a negotiated settlement, this will qualify for a 'Yes' resolution, regardless of if it is shaded red in the ISW map. An announcement of a negotiated settlement which gives Russia de jure control will not qualify. Actual control must be established.

If the ISW map is rendered unavailable, information from DeepStateMap (https://deepstatemap.live/) may be used. If information from both the ISW and DeepStateMap are rendered permanently unavailable, a consensus of credible reporting may be used. Note: Any temporary glitches or errors in the map which will not be considered.

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.
