Russian forces continue limited offensive operations in Sumy Oblast to establish buffer zones along the border, claiming control of small villages such as Myropillya in early May 2026 while Ukrainian units conduct counterattacks that have repelled several platoon-sized assaults. These incremental advances have secured key routes near Yunakivka and Nova Sich but remain far from the regional capital, with Russian milbloggers noting stalled redeployments and Ukrainian intelligence strikes disrupting Chechen units in the sector. A May 15 prisoner exchange involving detainees from the Sumy direction highlights ongoing diplomatic channels amid the fighting. Scheduled military developments, including potential reinforcements or Ukrainian deep strikes, could influence the pace of any further border incursions before the market's resolution window closes.

This market will resolve to “Yes” if, according to the ISW map, Russia captures the Sumy railroad station located on Pryvokzalna ploscha by March 31, 2027, 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 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.
