Top players like Jannik Sinner and Aryna Sabalenka enter the 2026 US Open as the consensus favorites to reach the singles finals, reflecting their hard-court dominance and recent Grand Slam success. Sabalenka, the two-time defending champion seeking a third straight title, heads the women's entry list alongside Elena Rybakina and Jessica Pegula, while Sinner leads the men's field ahead of Carlos Alcaraz and Alexander Zverev. Recent hard-court results, including the Cincinnati swing where form and availability shifted odds, plus official entry confirmations in July, have reinforced trader pricing around these contenders. Schedule strength, potential injuries, and qualifying outcomes for rising Americans or Europeans could still alter semifinal matchups before the August 23 start.
