The U.S. Open singles main draws got underway Sunday at Flushing Meadows under sunny skies, with a record $108 million purse on offer as the year's final Grand Slam opened in the second year of its 15-day format. USTA chief executive Craig Tiley said the largest purse in tennis history was aimed at giving players a fair share of revenue, while the organization continues to reject tying Grand Slam prize money to a fixed percentage of revenue. The package is up 20% from $90 million last year and 44% from $75 million in 2024, with singles champions set to earn a Grand Slam-record $5.5 million each and every main-draw singles player guaranteed at least $140,000. Jessica Pegula was scheduled first on Arthur Ashe Stadium against Elena-Gabriela Ruse, Daniil Medvedev against Hugo Gaston, Novak Djokovic in the night session against Mariano Navone, and Venus Williams closing against Sofia Kenin. With world No. 1 Jannik Sinner out and defending champion Carlos Alcaraz arriving after a long injury layoff, the 39-year-old Djokovic has a prime chance at another major. Players are still targeting a 22% revenue share by 2030, versus about 15% generally paid by the Slams, and Pegula has said revenue sharing remains a priority for the new Grand Slam Player Advisory Council.
