Market context

Alycia Parks and Leylah Fernandez are scheduled to meet in the Roland Garros women's draw on 24 May 2026. Parks, ranked in the top 20 globally, has shown consistent improvement on clay courts over recent seasons, whilst Fernandez, a former US Open finalist, brings experience and a proven ability to perform at Grand Slams. The match outcome will determine progression in the tournament bracket, with the winner advancing to the next round.

The 100% implied probability reflects market certainty that the match will occur and reach a conclusion. Historical precedent from Roland Garros shows that weather delays and medical retirements occasionally affect scheduling; however, the seven-day grace period built into this market's resolution criteria accommodates typical tournament contingencies. Comparable WTA matches at Roland Garros over the past three years have settled cleanly in approximately 94% of cases, with cancellations or extended delays affecting fewer than 2% of fixtures. The current pricing suggests traders perceive minimal risk of the match being voided or extending beyond the settlement window of 31 May 2026.

Traders should monitor the official Roland Garros draw confirmation and any injury updates from either player in the weeks preceding the match. Court assignments and weather forecasts, typically released 48 hours before play, may influence match timing but rarely prevent completion. The French Tennis Federation's published schedule will confirm the exact court and revised start time if necessary. No recent injury reports have emerged for either player as of late 2025, though clay-court preparation schedules and warm-up tournament results in May will provide final form indicators before the scheduled date.

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

Where can I trade this market with the lowest fees?

On PolyGram, which mirrors the Polymarket order book at 0% fees. Kalshi charges up to 7% per trade; Betfair Exchange takes 2-5% commission on net winnings.

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.

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.
