Market context
Kostyantynivka, a city of roughly 70,000 people in Donetsk Oblast, remains under Ukrainian control despite sustained Russian advances across the region since February 2022. The 0% implied probability on Polymarket reflects the settlement condition's specificity: full municipal capture as verified by ISW's colour-coded map, not partial encirclement or tactical gains. USDC holders pricing this contract on Polygon are effectively betting against Russian forces completing a full takeover of the municipality by 31 December 2026—a two-year window that currently prices such an outcome as negligible.
Russian forces have captured roughly 70% of Donetsk Oblast since the invasion began, yet several cities including Kostyantynivka have resisted complete enclosure despite proximity to active frontlines. Comparable cases like Mariupol (fully captured by May 2022) and Sievierodonetsk (captured by June 2022) took months of grinding urban warfare; Bakhmut required seven months. Kostyantynivka's larger population and Ukrainian defensive commitment suggest a slower conquest timeline if one occurs at all. The 0% pricing may underestimate tail risk given the contract's two-year duration and the unpredictability of attrition-based warfare.
Traders should monitor ISW map updates weekly, which represent the sole settlement mechanism. Recent reporting from the Institute for the Study of War (December 2024) indicates Russian forces are advancing methodically but slowly in Donetsk, with Kostyantynivka remaining several kilometres from active contact lines. Ukrainian military capacity, Western ammunition supplies, and any negotiated settlement would materially affect capture probability. The contract's extreme underpricing relative to historical conquest timelines suggests potential value for those assessing non-zero completion odds.

Resolution & payout
Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.
Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
FAQ
- Is this market available outside the US?
- Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.
- How does resolution work?
- Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.
- What's the difference between YES and NO shares?
- A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
- What does Polymarket cost to trade?
- Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.
- How reliable are the quoted odds?
- The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
