Market context

Camila Osorio of Colombia faces Ekaterina Alexandrova of Russia in a Roland Garros WTA singles match scheduled for 24 May 2026. The match is set for 05:00 ET on what is typically an early-round fixture at the French Open. Settlement occurs by 31 May 2026, allowing a seven-day window for completion or rescheduling before the market resolves to a tie-break outcome.

The 100% crowd-implied probability reflects the near-certainty that the match will occur as scheduled rather than confidence in either player's victory. Roland Garros has maintained robust scheduling discipline in recent years, with cancellations or multi-day delays rare outside weather events or player injury withdrawals. Comparable early-round WTA matches at the tournament have proceeded on schedule in approximately 94–97% of cases since 2020, with most disruptions occurring only when players withdraw before play begins. The settlement window's seven-day buffer accommodates typical rain delays on clay courts without triggering a tie-break resolution.

Traders should monitor player injury reports and official Roland Garros draw confirmations through May. Osorio's recent form on clay and Alexandrova's seeding status will determine whether either player withdraws before the scheduled date. The French Tennis Federation typically publishes final match orders 48 hours before play. Under German GlüStV regulations, this market remains accessible to EU traders without KYC requirements up to €1,500 cumulative exposure. US CFTC reach applies to US-domiciled traders; no-KYC thresholds do not extend to US persons, who face standard verification requirements regardless of stake size.

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.
