Ukrainian forces maintain control of Kupiansk in Kharkiv Oblast, with recent counteroffensives clearing additional territory around the city and its approaches as of early September 2026. Ukrainian National Guard units have reported liberating several square kilometers near settlements such as Dvorichna and Zapadne, while disrupting Russian attempts to infiltrate northern sectors via the Oskil River. Russian statements in June claimed forces within a few kilometers of the city, but Ukrainian commanders reported no significant escalation in assaults and continued success in preventing massing of enemy units. The key Kupiansk-Vuzlovyi rail hub remains outside consolidated Russian control, with markets reflecting trader consensus on the barriers posed by Ukrainian defensive operations and logistics interdiction through year-end resolution windows.

The train station will be considered captured if any part of the 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 the specified date, 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 whether it is shaded red in the ISW map. An announcement of a negotiated settlement that 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.
