Market context
Russia would need to take the Havrylivka intersection at 48.0728° N, 36.5235° E and keep it shaded red on the ISW map before the market can resolve **Yes**. As of the latest ISW assessments, Russian forces have repeatedly reported offensive activity in nearby directions but have not been credited with confirmed advances on 27 July, which keeps the implied path to capture narrow and mechanically dependent on a visible map change rather than claims alone.[1][7]
For a trader reading this as a tooling problem, the cleanest signal set is the ISW map itself, not front-line headlines. Comparable recent ISW updates show a pattern of claimed push efforts without confirmed gains, including no confirmed advances on 1, 18 and 27 July, while Ukrainian reporting has continued to describe active defence and counter-strike pressure across multiple sectors.[1][3][9] That history supports a low baseline probability unless the specific intersection appears red and stays that way through the relevant settlement rules.[2][8]
Catalysts to watch are sector-specific assault reports, any Ukrainian withdrawals from the Oleksandrivka/Pokrovsk-adjacent axis, and the next ISW map update after major ground actions. A programmatic workflow would typically poll the map layer or cached imagery on a schedule, alert on any red shading touching the target coordinate, and then verify persistence across subsequent updates before treating it as settlement-relevant; this matters because the market only counts a sustained change, not a transient glitch.[8] Recent battlefield reporting still points to heavy but inconclusive fighting, with 147 engagements on 25 July and no confirmed Russian gains in the latest ISW note, so the main trigger remains a true map revision rather than tempo alone.[1][6][7]
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.
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.
- 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.
- Do I need to KYC for this market?
- On Polymarket directly, no — it's wallet-based. Intermediary brokers like Kalshi Fees trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.
- 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.
