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 by November 30, 2025, at 11:59 PM ET. Kupiansk 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 November 30, 2025, 11:59 PM ET, the market will resolve to “No”. The territory of the municipality is shaded in light grey and is distinguished from bordering municipalities such as "Moskovka" with a darker grey line. If all area within the municipality is shaded in red, but 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. 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. Once Russia captures Kupiansk, any subsequent loss of control will not be considered towards the resolution of this market. Kupiansk Location: https://polymarket-upload.s3.us-east-2.amazonaws.com/Kupiansk+location.jpeg Location on Google maps: https://maps.app.goo.gl/ngCjTi39GSjbzaC46 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 which 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.

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.
