The closely contested market reflects an all-American men's semifinal between Ben Shelton and Frances Tiafoe that guarantees a U.S. player in the final against either Alexander Zverev or Karen Khachanov, offset by a women's final matchup of Aryna Sabalenka versus Elena Rybakina with no Americans remaining. Shelton's five-set upset of defending champion Carlos Alcaraz and Tiafoe's comeback from two sets down have boosted American momentum on the men's side, yet both face tough recovery from lengthy quarterfinals while Zverev holds strong recent form. Women's results have eliminated home hopes like Coco Gauff and Jessica Pegula, leaving outcomes dependent on final-week execution, rest, and head-to-head history in a draw that has already produced multiple upsets.
