Canadian Open: Jaume Munar vs Rinky Hijikata

Platform comparison

Market context

Polymarket is pricing this Canadian Open match at **90% YES** today, which means the contract is trading as a heavy view that Jaume Munar advances against Rinky Hijikata on-chain in USDC via Polygon conditional tokens. The market’s settlement rules matter here: if the match is played to a winner under the event’s rules, it resolves to the advancing player; if it is not played, is tied, or drifts beyond the seven-day window without a winner, it falls back to 50-50.[3]

That price sits well above the rest of the market’s pre-match estimates. Sportsbooks and model sites in the feed generally make Munar a modest favourite rather than a near-lock, with prices around Munar -135 to -143 and Hijikata +105 to +114, implying something closer to the mid-50s for Munar than 90%.[2][4][5][11] Comparable prediction venues are also aligned with a Munar edge, including a 95¢ “Yes” quote on an exact-score market for Munar 2-0 and model win probabilities around 55% to 57% for Munar.[9][5][13] That gap is useful context: on Polymarket, a 90% contract is not just a view on who is better, but also on whether the match is actually completed in the expected form.

The main catalysts are straightforward: the official order of play, any late withdrawal or walkover risk, and whether the match starts on the listed schedule of 3 August at 10:00AM ET.[1][3] Flashscore still lists the fixture for that time, while betting boards show a near-term start window, so traders should watch for any schedule movement, rain-related delay, or medical update that could push the market towards the 50-50 fallback.[1][2] For a trader holding the contract, the relevant question is not only who wins, but whether the on-chain token ultimately has a completed winner to settle against under Polymarket’s event rules.[3]

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.
