Market context
Anhelina Kalinina and Diane Parry are scheduled to meet in the opening round of Roland Garros on 24 May 2026. Kalinina, a Ukrainian player ranked in the 40s, has shown inconsistent form on clay in recent seasons, with early exits at major tournaments offset by occasional deep runs at smaller events. Parry, the French home player, has built a modest clay record and benefits from crowd support at Roland Garros, though her ranking typically sits outside the top 50. The 0% implied probability suggests either a technical issue with market initialisation or extremely high confidence in one player's withdrawal.
Historical context matters here: first-round matches at Roland Garros rarely see withdrawals after the draw is published, and both players have competing incentives to play. Kalinina's recent injury history—she has withdrawn from tournaments mid-season—creates some baseline risk, but Parry's status as a French player makes her withdrawal unlikely absent serious injury. The 50-50 resolution clause for cancellations or delays beyond seven days is relevant only if external factors (weather, scheduling conflicts) emerge closer to the date.
Traders should monitor both players' results and injury reports in the weeks preceding 24 May. Any announcement regarding either player's fitness or withdrawal from other tournaments in late May would shift expectations materially. The settlement window closes 31 May, allowing a week beyond the scheduled date for completion, which aligns with standard Roland Garros scheduling. Recent WTA injury patterns suggest tracking official tour communications rather than social media speculation.
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 Sport Prediction, which mirrors the Polymarket order book directly.
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.
