Canadian Open: Giovanni Mpetshi Perricard vs Botic van de Zandschulp

Platform comparison

Market context

Giovanni Mpetshi Perricard’s first-round meeting with Botic van de Zandschulp at the Canadian Open is a live ATP hard-court match-up, but the market is pricing it as if Perricard’s chance is effectively negligible, with the crowd-implied probability at 0% YES. That sits well outside the broader betting and analyst picture: Tennis.com’s match projection gives van de Zandschulp a narrow 53% edge, while the contest is generally being framed as close rather than one-sided. One reason is the contrasting profile of the players: Perricard is younger and the higher-listed market name, but van de Zandschulp is the lower-ranked player in some live listings and has the only head-to-head win, a straight-sets victory at Winston-Salem in 2025. [11][13][2][6]

For traders, the key context is that the market depends on the match actually being completed and on the official tournament result, not on pre-match sentiment. The National Bank Open site had the match listed with no points recorded, while live-score feeds showed it on the schedule in Montréal on 3 August, and some trackers later carried it into 4 August UTC, which matters because any postponement, retirement or abandonment can still change resolution outcomes if no winner is formally declared within the settlement window. The most material catalysts are therefore final order-of-play updates, court assignment, any weather-related delays, and whether either player finishes the match at all; Polymarket’s contract language also makes clear that a cancellation, tie or delay beyond seven days resolves to 50-50 rather than a simple void.
