Will Russia capture all of Kupiansk by...?

Resolution Criteria

This market will resolve to “Yes” if, according to the ISW map, Russia captures the entirety of Kupiansk, Kharkiv Oblast, (49.713460° N, 37.614763° E) between market creation and the specified date, 11:59 PM ET. Kupiansk will be considered captured if the entirety of the municipality 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”. The boundaries of the municipality are those shown under the “Ukrainian Settlements” layer on the ISW map. If all area within the municipality is shaded under a qualifying layer, however, the shading does not precisely match up with the border such that there is a tiny amount of unshaded area along the border of the municipality, this will still qualify for a "Yes" resolution. For the purpose of this market, areas separated from the main municipality through a darker grey line, such as in the southeast of Kupiansk (https://polymarket-upload.s3.us-east-2.amazonaws.com/h-b99a52275d.png), will not count towards the municipality. 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. Kupiansk Location: https://polymarket-upload.s3.us-east-2.amazonaws.com/Kupiansk+location.jpeg 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.

Russia has not captured the entirety of Kupiansk according to current ISW mapping, and prediction market volume is heavily concentrated against full Russian control of the municipality by the available deadlines. The market structures resolution across multiple date-specific outcomes, with the furthest deadline of 30 June 2026 attracting minimal backing. Resolution depends on the ISW Ukraine map showing the entire Kupiansk municipality shaded red by the relevant date.

Market structure

The market offers five outcome windows for full Russian capture of Kupiansk, each resolving on a distinct date up to 30 June 2026. Volume is heavily concentrated away from any 'Yes' outcome, with the June 2026 deadline — the most permissive available — attracting negligible backing. Resolution requires the entirety of the Kupiansk municipality to appear red on the ISW ArcGIS story map. Fallback sources are DeepStateMap and, if both are unavailable, a consensus of credible reporting.

Background

Kupiansk is a strategically significant rail and logistics hub in Kharkiv Oblast, eastern Ukraine, situated on the Oskil River. Russia briefly occupied the city following its February 2022 invasion but Ukrainian forces liberated it in September 2022 during a rapid counter-offensive. Since late 2022 and through 2023–2025, Russian forces have conducted sustained pressure along the Kupiansk axis, advancing incrementally in surrounding villages and exerting fire control over approaches to the city. The town's road and rail infrastructure makes it a longstanding Russian operational objective, and fighting in the broader district has been among the most attritional of the war. Despite sustained pressure, Ukrainian forces have maintained positions within and around the municipality throughout this period.

Key factors

The pace of Russian advance on the Kupiansk axis depends on several interconnected variables. Ukrainian defensive reinforcements, artillery availability, and Western materiel deliveries directly affect the ability to hold prepared positions along the Oskil River line. Russian force generation — including the rate of personnel replacement and armoured vehicle availability — determines offensive tempo. Seasonal conditions, particularly autumn mud and winter freeze-thaw cycles, historically influence mechanised movement in this region. Any broader ceasefire negotiation or pause in hostilities would halt territorial changes relevant to resolution. The resolution criteria specifically include negotiated transfer of actual control, meaning a peace agreement granting Russia de facto possession would qualify even without ISW map shading. Conversely, a negotiated settlement that remains unimplemented would not. ISW mapping methodology, which relies on reported geolocated evidence, can also lag real battlefield developments by hours or days, creating a gap between military reality and the resolution source.
