Market context

Iga Swiatek faces Sara Bejlek in the Roland Garros women's draw, with the match originally scheduled for 27 May 2026 at 05:00 ET. The current Polymarket pricing reflects near-certainty in Swiatek's favour, with conditional tokens trading at prices implying a 100% probability of her advancement. On Polygon, USDC liquidity pools are tight around this fixture, typical for matches involving heavy favourites where most traders have already positioned accordingly.

Swiatek's dominance on clay courts provides the foundation for this pricing. She has won Roland Garros twice (2022, 2023) and reached the final again in 2024, establishing herself as the surface's most consistent threat. Bejlek, a Czech player ranked considerably lower, offers limited historical precedent for upsetting top-seeded opponents at Grand Slams. Previous matches between players with comparable ranking gaps at Roland Garros have overwhelmingly favoured the higher-ranked competitor, particularly when that competitor is Swiatek on her preferred surface.

The settlement window closes 3 June 2026 at 09:00 UTC, allowing seven days from the scheduled date for the match to conclude. Traders should monitor the official Roland Garros draw confirmation and any weather disruptions affecting the clay courts, though the late May timing typically presents stable conditions in Paris. Swiatek's injury status and recent tournament performance in the weeks preceding Roland Garros will be the primary catalysts affecting conditional token pricing, though her historical reliability at this event suggests minimal repricing risk unless significant fitness concerns emerge.

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.
