Market context

Jan-Lennard Struff, the German player ranked around 40th on the ATP, faces Jaime Faria of Portugal in an early-round match at Roland Garros scheduled for 28 May 2026. The 100% implied probability reflects Struff's substantial ranking advantage and historical head-to-head record against lower-ranked opposition. Faria, a qualifier or lower-seeded entrant, would need to execute a significant upset to progress, though clay-court specialists occasionally produce unexpected results at the French Open where surface mastery can neutralise ranking disparities.

Historical precedent suggests that matches between players separated by 30+ ranking positions resolve in favour of the higher-ranked player approximately 85–90% of the time at Grand Slams, particularly in early rounds where preparation and match fitness favour established tour players. However, the settlement window extends to 4 June, providing a seven-day buffer beyond the scheduled date—relevant for monitoring whether rain delays or scheduling conflicts at Roland Garros might trigger the 50-50 resolution clause. Traders using conditional order logic should flag the match status feed; if either player withdraws before play begins, the market resolves 50-50 rather than defaulting to Struff's advancement.

For programmatic monitoring, the key dependency is match completion. If Struff leads but the match is suspended without conclusion before 4 June, the market settles 50-50 despite his advantage. ATP official draw updates and weather forecasts for the Roland Garros schedule should feed into any automated position management, particularly given clay courts' sensitivity to rainfall and the tournament's compressed scheduling in late May.

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.
