Canadian Open: Jaume Munar vs Rinky Hijikata

Platform comparison

Market context

Jaume Munar plays Rinky Hijikata in a Canadian Open first-round match that is scheduled for 3 August at 10:00 ET, and the market is currently pricing Munar as the clear favourite. On Kalshi, that shows up as about **55¢ YES** for Munar and **45¢ YES** for Hijikata, which is broadly in line with external moneyline markets that make Munar a modest favourite rather than a dominant one. BetVictor lists Munar at **-143** and Hijikata at **+105**, while Betstamp’s comparison view shows similar prices around **54% to 46%** once vig is stripped out; by contrast, Polymarket currently shows **$0 volume** on the same fixture, so its signal is less informative on this specific match.[2][3][4][10]

For platform comparison, the main read-through is that Kalshi and Polymarket present outcomes as **implied probabilities or contract prices**, while Betfair and Smarkets are typically easier to read as exchange-style prices or decimal odds after commission. That matters here because Munar’s edge looks strong enough to be reflected across books, but not so large that small differences in fees or conversion will change the underlying read. In practical terms, a 55% Kalshi-style price is close to roughly **1.82 decimal** before fees, which sits near the market range shown by other books once vig is accounted for.[2][4][10][11]

The main catalysts are straightforward: whether the match starts on schedule, whether the order of play is moved, and whether either player withdraws before first ball. Flashscore still lists the fixture for the stated start time, and several odds boards have already posted match and set markets, which suggests the event is live in pre-match books but still exposed to late scheduling changes.[1][2][7] Because this market settles on the player who advances, any retirement after the match begins still produces a winner unless the contest is not completed in a way that triggers the market’s fallback rules; if it is cancelled or delayed beyond the window without a result, the market reverts to 50-50.
