**No American is favored to claim either 2026 US Open singles title.** In the men’s final, top seed Alexander Zverev faces Ben Shelton after dispatching Karen Khachanov in straight sets; Zverev leads the head-to-head 5-0 and has won four straight matches without dropping a set. Shelton reached his first major final by upsetting Carlos Alcaraz in the quarterfinals and defeating Frances Tiafoe in the all-American semifinal, but he remains the underdog on hard courts against Zverev’s experience and serve. On the women’s side, Aryna Sabalenka and Elena Rybakina contest the final after eliminating the last American contenders, including Coco Gauff in the semifinals. Multiple seeded Americans advanced deep in both draws, yet the finals feature non-Americans holding the stronger recent form, head-to-head edges, and implied probabilities near 57% for the favorites. These outcomes align with the market’s 90.6% pricing on no American winner.
