Canadian Open: Alexis Galarneau vs Vit Kopriva

Platform comparison

Market context

Polymarket is pricing Alexis Galarneau to advance at **14% YES**, with settlement in USDC on Polygon through the usual conditional-token contract, so the market is effectively assigning Vit Kopriva an implied **86%** chance once fees and spread are stripped out. The match is the Canadian Open first-round meeting in Montreal, and the contract settles on who advances; if the match is not completed and an advance is awarded, that official advancement still governs the market. [2][3]

The historical frame is straightforward: there is no head-to-head record between the two, so traders are leaning on ranking level and recent results rather than prior matchup data. Kopriva is ranked around **70th** and Galarneau around **167th**, which helps explain the low price on the Canadian, while live tennis databases also show Kopriva with the stronger longer-run profile and Galarneau as the underdog on hard courts. Independent odds boards have echoed that gap, with Kopriva priced as the clear favourite and some models putting Galarneau in the low-20s, still well above the current market once the contract’s current crowd-implied level is considered. [2][6][15][16]

The main catalysts are simple but practical: confirm whether the match actually starts, whether it is completed, and whether any walkover, retirement or scheduling change creates a different settlement path under the market rules. The National Bank Open’s match page is the cleanest official source for whether play has begun and whether a winner is recorded, while live score pages can flag late changes before they reach the tournament feed. Because the settlement window runs well beyond the original slot, traders should also watch for postponements across the Montreal draw and any late tournament reshuffle that could move this beyond the seven-day rule.
