Summary

This market will resolve to “Yes” if, according to the ISW map, Russia captures the Kostyantynivka railroad station located on Pravoberezhna vulytsia by June 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 June 30, 2026, 11:59 PM ET, the market will resolve to “No”. For any change on the ISW map to qualify for this market’s resolution, the relevant shading indicating Russian control must persist through the next full ISW daily update cycle. If ISW skips a day, shading must persist until the next finalized ISW update is published, regardless of the date. Any continuous shading which reflects either “Assessed Russian Control”, “Assessed Russian Advance In Ukraine”, or “Assessed Russian Gains in the Past 24 Hours” will qualify. “Assessed Russian Infiltration Areas in Ukraine” will not qualify. 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.
