- Will Russia capture Sumy by March 31, 2027?3¢3%
Russian forces continue limited offensive operations along the northern Sumy Oblast border to establish a security buffer zone, yet assessments from the Institute for the Study of War show no confirmed advances into deeper Ukrainian-held territory as of mid-October 2026. Ukrainian units have conducted successful counterattacks northeast of Sumy city, including geolocated gains southeast of Yunakivka, while repelling Russian attempts to expand positions near settlements such as Ryasne and Sadky. Russian claims of substantial territorial seizures in the region remain significantly overstated relative to verified control, with incremental fighting focused on border areas rather than the city itself. Ongoing artillery, drone, and glide bomb strikes target Sumy region communities, but the absence of major breakthroughs or shifts in force posture sustains trader consensus around low probabilities for near-term capture of Sumy. Continued attritional dynamics and Ukrainian defensive actions remain the primary variables influencing market pricing.
Rules
This market will resolve to “Yes” if, according to the ISW map, Russia captures the Sumy railroad station located on Pryvokzalna ploscha between market creation and the specified date, 11:59 PM ET. The railroad station will be considered captured if any part of the train station icon is shaded under a below specified layer on the ISW map (https://storymaps.arcgis.com/stories/36a7f6a6f5a9448496de641cf64bd375) by the resolution date. Otherwise, the market will resolve to “No”. For any change on the ISW map to qualify for this market’s resolution, the relevant shading 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 under the following layers will qualify: - Assessed Russian-Controlled Terrain - Assessed Russian Advances Shading under the following layers will not qualify: - Assessed Russian Infiltration Areas - Claimed Russian Territory Once a qualifying condition is met, any subsequent loss of control will not be considered towards the resolution of this market. If Russia comes into control of the specified territory as a result of a negotiated settlement, this will qualify for a 'Yes' resolution, regardless of whether it is shaded under a qualifying layer on the ISW map. However, an announcement of a negotiated settlement that gives Russia de jure control will not qualify. Actual control must be established.
