Russian forces have conducted limited infiltration attempts and small-group advances into northern and peripheral areas of Kupiansk in Kharkiv Oblast through mid-2026, yet Ukrainian defenses have prevented consolidated control over the city or key sites such as the Pivdennyi railroad station. Ukrainian counteroperations in late 2025 and early 2026 recaptured most of the urban area after earlier Russian claims of seizure, leaving fragmented fighting in a gray zone. Persistent Ukrainian drone strikes, artillery interdiction, and fortified positions have slowed Russian momentum, with recent assessments showing stalled progress and equipment losses despite intensified pressure from multiple axes. Trader probabilities remain low for full Russian capture by December 31, 2026, reflecting the resource demands of parallel fronts in Donetsk Oblast and the absence of rapid breakthroughs.

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.
