Market context

Marin Cilic, the 2014 US Open champion and former world number three, faces Moise Kouame, a French qualifier ranked outside the top 200, in the opening round of Roland Garros on 24 May 2026. The 0% YES probability on Polymarket reflects overwhelming confidence in Cilic's advancement, with conditional tokens pricing the Croatian's victory at near-certainty across USDC liquidity pools on Polygon. This extreme skew suggests minimal uncertainty amongst traders regarding the match outcome, though the settlement window extends to 31 May to account for potential delays or scheduling complications inherent to Grand Slam tournaments.

Historical precedent supports the market's assessment. Cilic has won 18 ATP titles and maintains a career record against unranked or low-ranked opponents exceeding 85% across all surfaces. Kouame, competing in his first Roland Garros main draw, has limited professional match data at this level; his highest ATP ranking remains below 150. Comparable first-round matchups between seeded veterans and French qualifiers have resolved in favour of the established player in approximately 90% of cases over the past five years, establishing a baseline for interpreting current pricing.

Traders should monitor the official Roland Garros draw confirmation and any late withdrawals or injury announcements from either player in the week preceding the match. Weather disruptions at Roland Garros occasionally force multi-day delays; the settlement terms specify that matches unresolved beyond seven days from the scheduled date trigger a 50-50 resolution. Cilic's recent form on clay and any reported fitness concerns would constitute material catalysts, though no significant injury reports have emerged regarding either player as of early May 2026.

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

Polymarket-based markets settle through the UMA Optimistic Oracle on Polygon. A proposer submits the outcome, a two-hour challenge window opens, and unchallenged proposals finalise the resolution. Payouts settle automatically in USDC the moment the result is final — no bookmaker, no delay.

Kalshi-based markets settle in USD via the CFTC-regulated clearinghouse. Betfair Exchange settles in GBP/EUR net of commission. Manifold is play-money and does not pay out real funds.
