National Bank Open: Sho Shimabukuro vs Marin Cilic

Platform comparison

Market context

Sho Shimabukuro’s meeting with Marin Čilić at the National Bank Open was scheduled as a qualifying-round match in Montréal, with both players listed on hard court and the pre-match market leaning to Čilić on reputation and experience rather than any head-to-head history. The key structural point is that there is no recorded prior meeting between them, so pricing is being driven more by current level and surface fit than by a direct matchup record.[4][5][7][18]

That matters because the available form and model signals have been mixed. Flashscore listed Čilić at ATP 86 and Shimabukuro at ATP 94, while Tennis.com’s preview had Čilić as the projected winner at 63% to 37%; other models were closer, with Dimers putting Čilić at 56%. Tennis Majors also noted a 0–0 head-to-head since 2022, which means traders cannot lean on any established matchup pattern.[1][6][17][19]

For a 0% YES price to move, the main catalysts are straightforward: confirmation the match actually goes ahead in Montréal, any late withdrawal or retirement news, and whether the qualifier is shifted by scheduling or weather. Sofascore and similar live listings showed the fixture set for 2 August 2026 at 22:00 UTC, but the market only resolves on advancement, not just a completed first set, so an unfinished match or delay beyond seven days would push it towards the 50-50 fallback.[3][4][9][12]

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
