Market context
Francisco Cerundolo and Hugo Gaston are scheduled to meet in the first round of Roland Garros on 26 May 2026. Cerundolo, the Argentine ranked around 30th on the ATP tour, has shown steady improvement on clay courts over recent seasons, reaching the quarter-finals at Buenos Aires in 2025 and maintaining a positive win-loss record at Roland Garros historically. Gaston, the French qualifier or main-draw entrant depending on seeding, competes primarily on the Challenger circuit and has limited Roland Garros main-draw experience; his ranking typically sits outside the top 100. The 0% implied probability suggests either a data-entry error, missing fixture confirmation, or an assumption that one player will withdraw before the settlement window closes on 2 June.
Historical precedent matters here. First-round matches between a seeded or ranked player and a lower-ranked domestic challenger at Roland Garros favour the higher-ranked competitor in roughly 75–80% of cases, though upsets occur regularly on clay. Gaston's home advantage at Roland Garros—playing in France—provides some offset to the ranking disparity, but Cerundolo's superior tour ranking and recent clay-court form represent material advantages. The 0% reading is anomalous given standard matchup expectations.
Traders should monitor official Roland Garros draw confirmations and any injury announcements from either camp through late May. Cerundolo's participation in warm-up events immediately before Roland Garros will signal his form and fitness. Gaston's qualifying results, if he enters via that route, will provide updated information on his condition. Any withdrawal or postponement beyond 7 days triggers a 50-50 resolution under the market rules.
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
At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.
On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
FAQ
- Is this market available outside the US?
- Sport Prediction 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.
- 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 Sport Prediction?
- Zero. Sport 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.
- 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.
