Russian forces have conducted incremental advances toward and into Kostiantynivka since early 2026, employing small-unit infiltrations that created contested gray zones rather than rapid encirclement. By late July 2026, Ukrainian reports and ISW assessments indicated ongoing fighting in central areas, with Russian troops present but unable to consolidate full control despite claims of capture earlier that month. The city anchors Ukraine’s eastern fortress belt in Donetsk oblast, and its status affects logistics toward Sloviansk and Kramatorsk. Trader sentiment on full Russian capture by a given date reflects the slow pace of these urban operations, Ukrainian drone and artillery responses, and the absence of confirmed operational breakthroughs in the subsequent weeks.

Kostyantynivka will be considered captured if the entirety of the municipality 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 resolution date, 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.
The territory of the municipality is shaded in light grey and is distinguished from bordering municipalities with a darker grey line. If all area within the municipality is shaded in red, however, the shading does not precisely match up with the border such that there is a tiny amount of grey along the border of the city, this will still qualify for a "Yes" resolution.
Once Russia captures the entirety of the specified area, any subsequent loss of control will not be considered towards the resolution of this market.

The primary resolution source for this market will be the ISW Ukraine map. If the ISW map is rendered unavailable, information from DeepStateMap (https://deepstatemap.live/) may be used. If information from both the ISW and DeepStateMap are rendered permanently unavailable, a consensus of credible reporting may be used.
Note: Any temporary glitches or errors in the map will not be considered.
If Russia comes into control of this territory as a result of a negotiated settlement, this will qualify for a 'Yes' resolution, regardless of whether it is shaded red in the ISW map. An announcement of a negotiated settlement that gives Russia de jure control will not qualify. Actual control must be established.
