The market asks whether Russian forces will control the entire municipality of Kupiansk by 11:59 PM ET on November 30, 2025. Resolution hinges on the Institute for the Study of War’s interactive map of Ukraine, which tracks territorial control daily. A “Yes” requires the municipality’s light-grey area to be fully shaded red, indicating Russian occupation. Small mapping discrepancies along the border are disregarded, as long as the shading broadly matches the municipal boundary. One exception: a detached section in the southeast, separated by a darker grey line, is not considered part of the municipality for this market. Should a negotiated settlement grant Russia actual control over Kupiansk, the market would also resolve to Yes, even if the ISW map does not show red shading. An announcement of de jure control without physical occupation, however, would not suffice. Currently, traders assign a 0.0% probability to a capture by November 30. The same odds, 0.0%, apply to deadlines of December 31 (likely 2026), January 31, March 31, and June 30. The lone exception is the market for capture by December 31, most probably 2025, which stands at 13.5%. This suggests that market participants see almost no chance of Russia taking Kupiansk in the next few months, but a modest possibility by the end of this calendar year. Total trading volume across all Kupiansk-related capture markets is roughly $1.98 million, reflecting steady interest in a strategically important junction city on the Oskil River. The primary resolution source is the ISW map; if that becomes permanently unavailable, the DeepStateMap would be used, followed by a consensus of credible reports. The market’s design accounts for the fluidity of frontline mapping: temporary glitches in the ISW map are ignored, and once Russia captures the city, any subsequent loss of control does not reverse the resolution.

FAQ

What does “capture” mean for this market?

The entire Kupiansk municipality must be shaded red on the ISW Ukraine map, indicating Russian control. A small amount of grey along the borders is tolerated, but the southeast exclave is not included. Negotiated handover with actual control also counts.

Why is the probability for November 30 at 0%?

Prediction markets reflect collective expectations; traders currently see no chance of Russia achieving this by that date. The specific factors behind this assessment are not provided in the market data.

What happens if Russia captures Kupiansk after November 30, 2025?

The market resolves to No. Subsequent captures do not affect the resolution, even if they occur before other deadlines listed in related markets. Each deadline operates as a separate contract.

What is the ISW map, and why is it used?

The Institute for the Study of War produces a regularly updated, interactive map of control in Ukraine. It serves as a transparent, third-party source for verifying territorial claims in this market.

How much money has been traded on this event?

About $1.98 million in volume across all Kupiansk capture markets.
