The market-implied probability of a Russian capture by year-end 2026 currently sits at 14.0%. This market resolves “Yes” if the Institute for the Study of War (ISW) map shows the station shaded red by the resolution date of Jan 1, 2027. The shading must persist through the next full ISW daily update cycle, and temporary glitches are disregarded. A negotiated settlement that results in actual Russian control would also trigger a “Yes,” even without map shading. Once captured, any subsequent loss of control does not reverse the resolution. Battlefield developments around Kupiansk, updates to the ISW map, and the approach of Jan 1, 2027 are the formal conditions that could shift the number. A peace deal handing over control would also affect the market, per the stated rules.
FAQ
What is the primary resolution source?
The ISW Ukraine map, with DeepStateMap as a backup and credible reporting if both are unavailable.
How is the railroad station considered captured?
Any part of the station icon shaded red on the ISW map qualifies, provided the shading persists through the next full daily update.
What if ISW skips a day?
The red shading must then persist until the next finalized ISW update, regardless of the date.
Does a negotiated settlement count?
Yes, if Russia gains actual control of the territory, even in the absence of red shading on the map.
What happens if Russia captures the station but later loses it?
Only the first capture matters; subsequent changes do not affect resolution.
