Will Russia capture Verkhnia Tersa by...?

Resolution Criteria

This market will resolve to “Yes” if, according to the ISW map, Russia captures the intersection at 47.696500° N, 36.082206° E in Verkhnia Tersa, Zaporizhzhia Oblast, by the specified date 11:59 PM ET. The intersection will be considered captured if any part of the intersection 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, 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 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. Once Russia captures the intersection, any subsequent loss of control will not be considered towards the resolution of this market.

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.

Market trading on Polymarket places this outcome among the heavily minority-backed possibilities, with volume concentrated firmly on a 'No' resolution. The market asks whether Russian forces will capture a specific intersection in Verkhnia Tersa, Zaporizhzhia Oblast by 11:59 PM ET on 31 May 2026, as verified by the Institute for the Study of War (ISW) interactive map. Resolution requires the intersection coordinates to be shaded red on the ISW map and for that shading to persist through one full subsequent ISW daily update cycle.

Market structure

This is a binary yes/no market with a single outcome tracked. Volume is heavily concentrated on a 'No' resolution, reflecting the distance between current confirmed Russian positions and the specified intersection in Verkhnia Tersa. Resolution is determined by the ISW Ukraine map (storymaps.arcgis.com), with DeepStateMap as a fallback source. The deadline is 31 May 2026. A negotiated settlement transferring actual control to Russia would also qualify as 'Yes', but a de jure announcement alone would not.

Background

Verkhnia Tersa is a settlement in Zaporizhzhia Oblast in south-eastern Ukraine, a region that has been part of the broader contested front since Russia's full-scale invasion began in February 2022. Zaporizhzhia Oblast — partially occupied and partially held by Ukrainian forces — has seen intermittent but grinding pressure along multiple axes. The oblast is among four that Russia formally claimed to annex in September 2022, though Ukrainian forces have retained significant portions. Verkhnia Tersa sits within this contested zone, and any Russian advance toward it would form part of wider efforts to consolidate control across the oblast. The ISW, an American think tank, produces daily updated conflict maps that serve as widely cited reference tools for tracking territorial control in Ukraine.

Key factors

The primary structural factor is the physical distance between confirmed Russian front-line positions and the target intersection. Any advance would require sustained offensive pressure through Ukrainian defensive lines in the Zaporizhzhia direction, which has historically proven slow and costly for attacking forces. Seasonal conditions, including the state of ground and weather patterns through spring 2026, influence the tempo of mechanised operations. Ukrainian reinforcement capacity, Western military aid flows, and any shift in operational priority by Russian command could all alter the trajectory. A ceasefire or negotiated settlement — discussions of which have periodically surfaced in diplomatic reporting — could in theory transfer territorial control without battlefield advance, and the resolution criteria explicitly accounts for this. However, the criteria specifies that actual control, not merely a de jure announcement, must be established. ISW map methodology and update continuity also remain structural variables: any persistent unavailability of the ISW map would trigger use of DeepStateMap as an alternative resolution source.
