How this market resolves

This market will resolve to “Yes” if, according to the ISW map, Russia captures the Sumy railroad station located on Pryvokzalna ploscha by September 30, 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 September 30, 2025, 11:59 PM ET, the market will resolve to “No”.

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.

Once Russia captures the railroad station, any subsequent loss of control will not be considered towards the resolution of this market.
