This market will resolve to “Yes” if, according to the ISW map, Russia captures the Kupyansjk-Vuzlovij railroad station located between Zaliznychna Vulytsia and Zaliznychnykiv Ploshcha (49.654359° N, 37.644326° E) by February 28, 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 February 28, 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 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.

If the ISW map is rendered unavailable, information from DeepStateMap (https://deepstatemap.live/) may be used. If information from both the ISW and DeepStateMap are rendered permanently unavailable, a consensus of credible reporting may be used. Note: Any temporary glitches or errors in the map will not be considered.
Russian forces have sustained offensive pressure in the Kupiansk direction throughout 2026, focusing infiltration missions and incremental advances to approach Kupiansk-Vuzlovyi, a key railway junction southeast of Kupiansk that could disrupt Ukrainian logistics on the Oskil River's west bank. Ukrainian reports and assessments from mid-August confirm ongoing Russian activity in the immediate Kupiansk-Vuzlovyi and Kivsharivka sectors alongside Ukrainian counterattacks that have regained ground in northern areas near Zapadne. Russian military statements have repeatedly claimed control or encirclement of the settlement since January, but these assertions lack corroboration from geolocated evidence or independent analysis, with Ukrainian forces retaining positions. Broader Russian efforts to envelop Kupiansk continue without confirmed seizure of the junction itself. Scheduled or intensified operations in the coming weeks could influence momentum before any market resolution window.
