Canadian Open: Juan Manuel Cerundolo vs Hamad Medjedovic

Platform comparison

Market context

Polymarket is pricing this USDC-settled, Polygon-based conditional token contract at **100% YES**, so the market is currently treating Hamad Medjedovic’s advance as a virtual certainty in the Canadian Open meeting with Juan Manuel Cerundolo. The exchange logic matters here: if the match is not completed in a way that produces a winner within the market’s settlement window, or if it is cancelled or left unresolved beyond seven days, the contract can still resolve 50-50 rather than paying out either side outright.

That near-certain price sits against a head-to-head that already favours Medjedovic. The pair have met twice on the ATP tour, both times at Roland-Garros, with Medjedovic winning both matches and leading the series 2-0 overall[1][2][10][17]. More broadly, both players have been active at the ATP level this year, with listed rankings around ATP 50 for Cerundolo and ATP 73 for Medjedovic in event data, which helps explain why the market may be leaning heavily towards the Serbian despite Cerundolo’s left-handed clay-court profile[5][12]. For Polymarket users, the current 100% print leaves little room for price discovery unless the event is delayed, rescheduled, or materially disrupted.

The main catalysts to watch are match confirmation, court assignment, and any ATP scheduling change at Montreal, because the contract settles on who *advances* rather than on pre-match expectations. Live-score listings show the fixture as part of the National Bank Open in Montreal on hard courts, but published times vary across feeds, so start-time slippage is the practical risk factor for a settlement edge case[3][4][5][11][12][18]. If the match starts, the only way the market should drift away from a straight player winner is through an abandonment or a prolonged delay beyond the seven-day rule built into the market terms.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

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.
