Ben Shelton leads the ATP Montreal winner market at an implied 68% probability as the defending champion who has reached a second straight National Bank Open final with dominant hard-court form, including straight-sets semifinal wins. Brandon Nakashima sits at 32% after advancing to his first Masters 1000 final via an upset run that eliminated higher-ranked contenders, positioning him as a live underdog in the all-American championship match. Earlier bracket attrition removed top seeds such as Zverev, Sinner, and Alcaraz, concentrating trader focus on the two finalists’ recent momentum, serve-volley execution, and experience in deciding sets on outdoor hard courts. Market pricing reflects the wisdom of crowds assessing Shelton’s title defense edge against Nakashima’s breakthrough potential in what remains a competitive final.
