Kalshi prices Zverev at 49% to win the US Open, reflecting his status as the only player to reach all four Grand Slam semifinals this season and heavy favorite to clear unseeded Karen Khachanov on Friday. Ben Shelton trails at 36% after his stunning upset over defending champion Alcaraz, setting up a semifinal with fellow American Frances Tiafoe that guarantees one American will reach the final. Zverev's path looks clearer, but Shelton's momentum from his biggest career win adds intrigue to what shapes as a two-tier contest between the German and the two American semifinalists.
