Market context
Grass Court Championships: Elina Svitolina vs Eva Lys. The market is currently pricing the outcome at 100% YES, meaning crowd-implied probability sits at that level. Settlement is scheduled for 2026-06-24T09:00:00Z. Unlike a sportsbook, the price you see is set by buyers and sellers competing in a live order book — there is no house edge or bookmaker margin to fade.
World-affairs prediction markets price discrete geopolitical outcomes — ceasefires, treaty signings, leadership transitions — and tend to drift on rumour and snap-correct on official announcements.
Watch for the underlying catalysts that move this category: each official announcement, dataset release, or scheduled milestone generally produces a step change in the implied probability. Trades execute instantly on Polygon, and shares pay $1 each at resolution if your side wins.
Methodology
We track Grass Court Championships: Elina Svitolina vs Eva Lys on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.
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
- 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.

- Zero. Prediction Market UK routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- How fast are USDC deposits?
- Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.
