Canadian Open: Jaume Munar vs Rinky Hijikata

Platform comparison

Market context

Jaume Munar and Rinky Hijikata are listed for a Canadian Open first-round match that is due to be played on hard courts, with the market already priced heavily towards Munar. Current sportsbook lines generally make Munar a modest favourite, roughly in the mid-50s on implied probability, while some prediction models sit near 55% for Munar and 45% for Hijikata; that sits well below the crowd’s 92% YES reading, so the market is treating the favourite as much more one-sided than the wider betting consensus suggests.[2][4][5][16]

That gap matters because ATP first-round matches can swing on late timing, surface feel, and whether the underdog gets an early foothold; comparable pricing in the last 24 hours has still kept Hijikata very much live, rather than a token price. When a market is this far above the bookmaker and model range, it usually reflects either a strong expectation that the named player will advance, or some non-price signal the crowd is overweighting.[2][4][5]

The main catalysts to watch are simple: whether the match starts as scheduled, any last-minute order-of-play change, and any official retirement, postponement, or walkover risk before completion. Flashscore and other live listings still show the fixture on the board, while Polymarket’s own rules mean a cancellation, tie, or delay beyond seven days would settle 50-50 rather than to either player.[1][3]
