Canadian Open: Daniel Merida Aguilar vs Liam Draxl

Platform comparison

Market context

Daniel Merida Aguilar is set to face Liam Draxl in the Canadian Open, and the market’s 41% crowd-implied price for Merida sits below several bookmaker-style views that still make him a modest favourite. Polymarket is currently quoting the match as roughly 57% for Merida and 43% for Draxl, while Kalshi’s matching event shows the same 57%/43% split in cents, which makes the current platform spread more about pricing format than direction.[1][14] On decimal-odds books, the same matchup has been posted around 1.63 for Merida and 2.10 for Draxl, which translates to an implied edge closer to the mid-50s for Merida before margin, so the crowd price is noticeably cooler than the main bookmaker consensus.[4][15]

That gap matters because pre-match tennis markets often move sharply on line-up news, court-time certainty and whether a player is confirmed to start after earlier-round scheduling changes. Flashscore and Livescore were still listing the fixture, while the market itself allows a 50-50 settlement if the match is cancelled, tied, or delayed beyond seven days without a winner, which is less typical of standard sportsbook settlement rules and more relevant to exchange-style products.[2][6][12] Traders comparing Polymarket with Kalshi, Betfair or Smarkets should also factor in access and fees: Kalshi’s interface shows straight dollar-cents pricing, while traditional books and exchanges usually differ on commission, margin and local KYC availability, so the same sporting view can land at different effective costs even when the directional probability is similar.[3][13][14]
