Ben Shelton enters the Montreal final as defending champion and the clear market favorite at 66% implied probability, driven by his straight-sets run through the draw and strong 2026 hard-court form that includes multiple titles. Brandon Nakashima sits at 34.3% after reaching his first Masters 1000 final, capitalizing on a favorable path and recent consistency on North American hard courts. Both Americans have traded wins in recent meetings, but Shelton’s superior recent results, serving power, and experience in high-stakes matches underpin trader consensus favoring him over Nakashima. With the title on the line in a one-off match, any late fitness or tactical adjustments could still shift probabilities.
