Canadian Open: Giovanni Mpetshi Perricard vs Botic van de Zandschulp

Platform comparison

Market context

Giovanni Mpetshi Perricard’s match with Botic van de Zandschulp in Montreal is being priced very differently across platforms, which makes the current **0% YES** on Polymarket look more like a stale or unavailable market than a live consensus. Traditional books are broadly treating van de Zandschulp as the slight favourite: Sportsbet lists Perricard at 2.17 and van de Zandschulp at 1.69, while another Australian board has Perricard at $1.72 and van de Zandschulp at $2.10, a narrower split that still implies Perricard is not the favourite[17][18]. By contrast, Kalshi’s Montreal tennis market showed Perricard at 64¢ and van de Zandschulp at 70¢ in separate event legs, illustrating how exchange-style markets express probability in cents rather than decimal odds[14].

Comparable previews also point to a close contest rather than a near-certainty. One model-based preview had Perricard at 54% and van de Zandschulp at 46%, while another odds-derived estimate put Perricard at roughly 59.9%[10][9]. Several bookmakers have leaned towards a tight, serve-heavy match, including a tip on over 20.5 games and another market on over 24.5 games, which is consistent with Perricard’s profile as a big server and van de Zandschulp’s ability to extend sets[3][4].

For traders, the key catalysts are simple: whether the match is actually played, whether either player withdraws, and whether the start time slips inside the seven-day settlement window. The market description says it resolves only if one of the two advances, and a cancellation, tie, or delay beyond seven days would force a different outcome[market description]. On platforms like Betfair or Smarkets, fees and KYC rules matter as much as price: exchange markets usually allow direct buying and selling with commission rather than the embedded margin typical of sportsbooks, but access depends on jurisdiction and identity checks, so the executable probability can diverge from the headline odds even on the same match.
