Resolution criteria on PolyGram: This market will resolve to “Yes” if, according to the ISW map, Russia captures the intersection at 48.313021° N, 36.925497° E in Serhiivka, Donetsk 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.

Market outcomes
| April 30 | 0% YES | 100% NO |
| May 31 | 4% YES | 96% NO |
Serhiivka is a small settlement in Donetsk Oblast positioned along the contested frontline between Russian and Ukrainian forces. The market concerns whether Russian forces will establish control over a specific intersection within the settlement by 31 May 2026, as documented by the Institute for the Study of War's publicly maintained control map. Current order book activity on Polymarket reflects zero probability, indicating traders assess Russian capture of this precise location as extremely unlikely within the specified timeframe.
The 0% implied probability reflects the broader stalemate characterising the Donetsk frontline since late 2022. Comparable settlements in the oblast have changed hands infrequently over the past eighteen months, with Russian advances measured in kilometres rather than towns. Historical precedent suggests that capturing and holding specific urban coordinates requires sustained offensive momentum, concentrated resources, and Ukrainian defensive collapse—conditions largely absent in this sector. The ISW map's granular tracking means resolution depends on documented Russian control rather than tactical proximity.
Traders monitoring this market should track Russian offensive operations in central Donetsk, particularly any breakthrough attempts near Pokrovsk or repositioning of mechanised units toward Serhiivka's vicinity. Recent reporting from the Financial Times and Ukrainian military assessments indicate Russian forces remain stretched across multiple fronts, limiting capacity for new offensives. The settlement's distance from major Russian-held logistics hubs and its position within Ukrainian-controlled territory create substantial friction against capture. Any significant shift in frontline dynamics or Russian force concentration would warrant reassessing the current probability assessment.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a two-hour dispute window opens, and if no one stakes a counter-claim the payout is final. Contested outcomes escalate to UMA token-holder voting. Payouts clear in USDC to the winning side.
The mechanics for trading "Will Russia capture Serhiivka by...?" are the same as any other PolyGram event contract. Each YES share resolves to $1 if the event happens, or $0 if it doesn't. The current price between 0¢ and 100¢ is the market's probability estimate, set live by the order book.
$6K in lifetime turnover and $2K of resting liquidity puts this market in the below the median by volume for ukraine contracts on PolyGram. Order-book depth is thin — large orders may need to be split across the book or executed as limit orders.
The market has been open for around a month — fresh enough that information asymmetry remains a real factor.
Higher-volume markets tend to have tighter spreads and faster price discovery — meaning the displayed YES/NO percentages are more likely to reflect the true crowd-implied probability rather than a single trader's directional view.
Resolution is handled by the UMA optimistic oracle on Polygon. A proposer submits the outcome, a 2-hour dispute window opens, and if uncontested the payout is final. Contested outcomes escalate to UMA token holders.
This prediction market is scheduled to close on 31 May 2026. After the resolving event occurs, settlement typically clears within 24 hours once the UMA optimistic oracle confirms the outcome. All payouts are in USDC on the Polygon network.

Prediction-market positions can lose 100% of staked capital. Outcomes are uncertain by definition — historical accuracy of crowd-implied probabilities is high in aggregate but not for any single market. PolyGram does not provide investment advice. Trade only with capital you can afford to lose.
Regulatory status varies by jurisdiction. Germany, the United States, and most EU countries treat Polymarket-style event contracts under one of three frameworks: financial derivative, gambling product, or unregulated novel asset. Consult local counsel before trading.
