Alexander Zverev leads trader sentiment as the top seed and only player to reach the quarterfinals at all four 2026 majors, building on straight-set wins and improved serving consistency after early five-setters at the US Open. Ben Shelton’s 37% implied probability reflects momentum from his record-setting five-set quarterfinal upset of defending champion Carlos Alcaraz—the latest finish in tournament history—securing an all-American semifinal against Frances Tiafoe. Tiafoe’s 9% share stems from his own five-set comeback against Alex Michelsen, while Karen Khachanov and Alexander Blockx sit at 8% and below amid their quarterfinal matchups. Absent world No. 1 Jannik Sinner and an early Novak Djokovic exit have opened the draw, favoring Zverev’s experience and Shelton’s recent hard-court form heading into the final weekend.
