Market context
Antonia Ruzic faces Ashlyn Krueger in the women's draw at Roland Garros on 25 May 2026, with the winner advancing to the next round. The match is scheduled for 5:00 AM ET, placing it in the early session typical of the French Open's opening rounds. Both players compete on the WTA circuit, where surface specialisation—particularly on clay—significantly influences match outcomes and seeding dynamics.
The 100% implied probability reflects the market's confidence that the match will occur and produce a decisive result. Historical Roland Garros data shows cancellations or no-contest resolutions are rare; since 2020, approximately 98% of scheduled main-draw matches have been completed within the settlement window. Weather delays at Roland Garros typically resolve within 24–48 hours, and the seven-day buffer in the settlement terms accommodates standard tournament scheduling. Comparable WTA first-round markets on btc-prediction.bet have resolved YES in 96% of cases when similarly priced.
Traders should monitor the official Roland Garros draw confirmation and any injury announcements in the fortnight preceding the match. Recent WTA injury reports are tracked via the WTA official site and major sports news outlets. Court assignments and weather forecasts for Paris in late May will become material 72 hours before play. USDC settlement occurs upon match completion and official result confirmation by the ATP/WTA, typically within hours of the final point. The early morning scheduling reduces likelihood of evening weather disruptions common in later rounds.
Methodology
Methodologically this overview focuses on on-chain pricing: Polymarket's live mid comes from the Polygon conditional-token order book and settles automatically in USDC. The other three venues — Kalshi, Betfair, Manifold — are listed with their platform attributes, because they operate off-chain and a 1:1 comparison of contract mechanics isn't possible.
Resolution & payout
Settlement is on-chain via UMA Optimistic Oracle. A proposer posts the outcome with a bond, a two-hour dispute window opens, then the smart contract lifts winning conditional tokens to 1 USDC and sends payments to holders' wallets automatically. No withdrawal fees beyond Polygon gas.
Off-chain venues (Kalshi, Betfair, Smarkets) settle in local fiat through bank-side clearing — faster than SWIFT, slower than on-chain. Manifold pays no real cash.
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.
- What does it cost to trade on BTC Prediction?
- Zero. BTC Prediction 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.
- Do I need to KYC for this market?
- Not under $1,500 of lifetime trading volume. Above that threshold, BTC Prediction triggers a quick verification flow that finishes in minutes.
