Market context
Cobolli and Svajda are scheduled to meet in the opening rounds of Roland Garros on 31 May, with the Italian ranked substantially higher and favoured at 89 per cent by the crowd. The match timing—5:00 AM ET—places it in the early-morning slot typical of Roland Garros scheduling, which occasionally sees weather-related delays or court reassignments that could affect preparation and momentum. No significant injury reports or withdrawals have emerged for either player in the past 48 hours.
Cobolli's seeding advantage and recent form provide the foundation for the high probability. The 22-year-old Italian has climbed to around 30th in the ATP rankings and reached multiple ATP 250 finals in 2024–2025, establishing himself as a consistent performer on clay. Svajda, an American ranked outside the top 100, has limited clay-court pedigree and no previous main-draw victories at Grand Slams. Historical matchups between players with this ranking disparity at Roland Garros favour the higher-ranked competitor in roughly 85–90 per cent of cases, aligning closely with current market pricing.
Traders should monitor the official Roland Garros draw confirmation and any late weather forecasts for Paris in late May, as thunderstorms occasionally force schedule compression. Court assignments will be published closer to the event date. Cobolli's performance in the week leading up to Roland Garros—particularly any ATP 250 events in May—could shift confidence if he shows fatigue or injury concerns. Svajda's recent match results will be less influential given the baseline expectation, but a surprise run at a preceding tournament could tighten odds marginally.
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.
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?
- Prediction Today is available in most jurisdictions where Polymarket isn't directly accessible. Polymarket itself is geo-blocked in the US/UK/EU. Always check local regulations.
- 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 Prediction Today?
- Zero. Prediction Today routes every order to the live Polymarket order book; the only cost is the Polygon network fee, typically under $0.01 per transaction.
- Do I need to KYC for this market?
- Not under $1,500 of lifetime trading volume. Above that threshold, Prediction Today triggers a quick verification flow that finishes in minutes.
