Russian forces have maintained pressure on Kostiantynivka in Donetsk Oblast through incremental advances, small-unit infiltrations, and flanking maneuvers since the battle intensified in late 2025, turning parts of the city into a contested gray zone. Ukrainian units, including mechanized brigades, have repelled multiple assaults near the city and surrounding settlements as recently as mid-September 2026, though Russian artillery, drones, and glide bombs continue to degrade logistics and positions. Analysts note slow Russian progress without rapid breakthroughs, consistent with high casualties and limited territorial gains across the broader front. Trader sentiment reflects ongoing urban fighting, Ukrainian defensive resilience in the fortress belt, and the absence of confirmed major shifts in control that would resolve specific location-based outcomes.

The building station will be considered captured if any part of the buildings grey area 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 the specified date, 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 area, any subsequent loss of control will not be considered towards the resolution of this market.
