Resolution criteria

This market will resolve to “Yes” if, according to the ISW map, Russia captures the Kostyantynivka railroad station located on Pravoberezhna vulytsia by September 30, 2026 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, 2026, 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. Train Station ...
