Russian forces have conducted limited offensive operations in northern Sumy Oblast through August 2026, focused on establishing buffer zones along the border, but assessments from the Institute for the Study of War show no confirmed territorial gains in recent weeks amid Ukrainian counterattacks near areas such as Mogrytsia and Sadky. Earlier Russian claims of advances into villages like Loknia and Myropilske have yielded only incremental progress at high cost, with overall offensive pace across Ukraine slowing sharply compared to prior periods. Ukrainian defenses have adapted effectively to repel probes while sustaining artillery and drone pressure, and Russian efforts remain constrained by manpower limits and competing priorities on other fronts. These dynamics underpin low trader-assigned probabilities for city capture by near-term deadlines, though continued border strikes and any shifts in Ukrainian force allocation or external support could influence ground conditions within resolution windows.

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 March 31, 2027, 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 if it is shaded red in the ISW map. An announcement of a negotiated settlement which 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.
