Market context
Aleksandar Kovacevic faces Rafael Jodar in the opening round of Roland Garros on 24 May 2026, with the American ranked considerably higher on the ATP ladder. The 0% implied probability suggests market participants either expect a withdrawal or perceive an unusually wide skill gap for a Grand Slam draw. Given that both players must clear qualifying or receive direct entry, the market's extreme positioning warrants scrutiny of recent form and draw confirmation.
Kovacevic has historically competed at ATP 250 level and below, whilst Jodar operates in similar territory on the professional circuit. When unseeded or lower-ranked players meet in Grand Slam first rounds, the favourite typically carries 65–75% implied probability depending on ranking differential and recent match records. The 0% reading here is an outlier that reflects either missing information about player availability or an error in market calibration rather than genuine certainty about the outcome.
Traders should monitor the official Roland Garros draw release and any late withdrawals through late May. Injury announcements or late qualifying results could shift the matchup entirely. The settlement window extends to 31 May, allowing seven days beyond the scheduled date for completion—a standard buffer for clay-court tournaments where weather delays are common. Confirmation of both players' participation in the main draw remains the primary catalyst; without it, the market may resolve to 50-50 under the cancellation clause.
Methodology
This page reviews Roland Garros ATP: Aleksandar Kovacevic vs Rafael Jodar across five venues. We show live odds for Polymarket-based markets (sourced from the Polygon order book); for other venues we list platform attributes, since the comparable contracts are not exposed via a public API on every venue. Every CTA points at PolyGram — the application we operate, where you trade directly against the Polymarket order book at 0% fees.
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.
