Market context
Kaitlin Quevedo faces Leolia Jeanjean in the first or second round of Roland Garros 2026, with the match originally scheduled for 25 May at 5:00 AM ET. The 100% YES probability on Polymarket reflects that this contract has already settled or the match outcome is effectively determined—either the fixture has concluded with Quevedo advancing, or market participants have priced in near-certainty based on available information. On Polygon, USDC holders backing the YES conditional token would receive full payout at settlement on 1 June.
Jeanjean, a French clay-court specialist ranked around 60–80 in recent seasons, has shown inconsistent form at Grand Slams but performs better on home soil. Quevedo, an American player with limited WTA ranking history, would be considered the underdog in most matchups. Historical precedent suggests that when Polymarket prices a women's tennis match at 100%, either the match has already been played and the winner confirmed, or the market has closed to new trading due to imminent settlement. The extreme probability leaves no room for upset pricing, which typically emerges only when there is genuine uncertainty about player fitness, weather delays, or draw complications.
Traders should monitor the official Roland Garros draw confirmation and any injury announcements through late May. Weather delays at Roland Garros are common, though the settlement window extends only seven days beyond the scheduled date—any postponement beyond 1 June would trigger a 50-50 resolution. Court assignments and match timing adjustments could affect player preparation, particularly given the early morning slot originally scheduled.
Methodology
This page is a comparison snapshot: one live quote (Polymarket), four reference venues with their key attributes, and a single execution path — every trade button routes to PolyGram, which mirrors the Polymarket order book directly.
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?
- PolyGram 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.
- 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, PolyGram triggers a quick verification flow that finishes in minutes.
