Resolution criteria on PolyGram: 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”.

Kupiansk-Vuzlovyi is a railway junction in eastern Ukraine's Kharkiv Oblast, located roughly 40 kilometres south-east of the city of Kupiansk. Russia has pursued incremental territorial gains in this sector since its 2022 invasion, though progress has been measured in hundreds of metres per month rather than kilometres. The specific resolution criterion—whether the ISW map shows the station shaded red by 28 February 2026—depends on Russian military capability to advance through contested terrain whilst Ukrainian forces maintain defensive positions. The current 0% implied probability on Polymarket's order book reflects trader assessment that such a capture within the next fourteen months remains highly unlikely given the frozen or slowly-shifting frontline dynamics observed throughout 2024.
Historical precedent suggests caution in dismissing low-probability military outcomes entirely. Russia captured Mariupol's Azovstal steelworks in May 2022 after months of siege; conversely, Ukrainian forces retook Kharkiv city and surrounding areas in September 2022 despite earlier Russian advances. The Kupiansk sector has seen Russian forces stall repeatedly when attempting to consolidate gains, with Ukrainian counterattacks periodically disrupting supply lines. The fourteen-month timeframe to resolution is substantial enough that force composition, ammunition availability, and command decisions could shift materially.
Traders should monitor Russian offensive tempo in Kharkiv Oblast, particularly any sustained breakthrough operations near Kupiansk. Western military aid announcements and Ukrainian force rotations will influence defensive capacity. The ISW map updates regularly based on verified frontline reports; traders relying on this resolution criterion should track ISW's methodology changes and any disputes over territorial control claims near the station coordinates.
