Market context
Russia has not yet been shown to control the Havrylivka intersection on the ISW map, and the market’s current 0% YES implies traders see a capture by the end-2026 settlement window as a very low-probability event. That fits the wider front line picture in late July: ISW said Russian forces had been losing ground at an average of about 1.6 square kilometres per day over the preceding period, while separate ISW updates on 24–26 July reported no confirmed advances on those days. [1][3][10]
For context, comparable ISW-tracked pockets tend to move only when Russia can convert infiltration into durable consolidation, not merely temporary penetration. ISW’s 5 July assessment said Russian forces had infiltrated Kostyantynivka but had not consolidated or seized it, and Ukrainian officials and Russian milbloggers disputed Russian claims of capture; that same pattern is the main reason short-dated capture markets often trade below the headline intensity of fighting. Cross-platform pricing also appears restrained: Polymarket’s own Havrylivka contract showed a leading outcome at only 5% in early May, with the shortest-dated outcome at 0%, indicating that prediction-market participants have not been pricing in near-term seizure. [2][8]
Traders should watch whether the front shifts from pressure to map-visible control near the Oleksandrivka axis, because any red shading on the ISW map must persist through the resolution timestamp to count. Recent reporting from the Ukrainian General Staff and media summaries has continued to place the heaviest Russian assault tempo farther south and east, especially around Pokrovsk, while the Kharkiv and Dnipro-adjacent sectors have seen sporadic or no confirmed advances on several recent days. If Russia fails to produce a sustained breakthrough before autumn, the 0% crowd-implied line may stay anchored; if a local collapse does occur, the move would likely show up first in ISW shading rather than in rhetoric or single-day claims. [4][5][7][9]
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
