Market context
Huliaipole, a municipality in Zaporizhzhya Oblast in south-eastern Ukraine, remains under Ukrainian control as of late 2024. The market asks whether Russian forces will capture the entire town by 28 February 2026. The 0% crowd probability reflects the current military stalemate in the region, where Russian advances have slowed considerably since the initial 2022 offensive. ISW mapping serves as the sole arbiter, requiring the entire municipality to appear shaded red on their ArcGIS interface for settlement.
Comparable cases from the Donbas conflict show that municipal-level captures typically require sustained offensive momentum and logistical capacity. Mariupol took roughly three months of intense urban warfare; Sievierodonetsk fell after weeks of grinding attrition. Huliaipole lies roughly 40 kilometres from the nearest Russian-held territory, meaning any assault would demand either a major breakthrough or a prolonged encirclement strategy. The current front lines have moved little in this sector since mid-2023, and Russian forces face manpower constraints documented by Ukrainian and Western intelligence assessments.
Traders monitoring this market should track Russian force deployments in Zaporizhzhya Oblast, particularly any concentration of mechanised units or engineering assets signalling offensive preparation. Announcements from Ukraine's General Staff regarding defensive fortifications or counteroffensive operations in the region carry weight. Winter conditions typically reduce offensive operations, though this depends on ground freeze patterns. Polymarket and Kalshi both carry this contract; Polymarket displays decimal odds whilst Kalshi uses American odds, and fee structures differ materially on smaller-volume markets like this one. Settlement hinges entirely on ISW's cartographic decisions, which occasionally lag ground reality by weeks.
Methodology
We read Will Russia capture all of Huliaipole by 2026? from four platform perspectives: Polymarket (on-chain CLOB), Kalshi (CFTC-regulated exchange), Betfair Exchange (sports book exchange), Smarkets (peer-to-peer betting exchange). Polymarket's live mid is the canonical probability; the side-by-side columns benchmark fees, KYC, settlement currency and deposit rails so you can choose the venue that fits your jurisdiction and trade size.
Resolution & payout
Polymarket settles via UMA Optimistic Oracle on Polygon. A proposer posts the outcome with a bond, the two-hour window runs, then the smart contract pays USDC.
Kalshi settles USD through the CFTC-regulated clearinghouse — the cleanest variant, with heavier KYC. Betfair Exchange settles in account currency (GBP/EUR), net of 2-5% commission. Smarkets follows the same model as Betfair with a lower default 2% commission.
