Recent developments in the 2026 US Open men's draw, including Ben Shelton's record late-night quarterfinal upset of defending champion Carlos Alcaraz and Frances Tiafoe's comeback victory, have positioned two American semifinalists against Alexander Zverev and Karen Khachanov, heightening domestic interest ahead of the September 13 final. This setup, combined with Novak Djokovic's early exit, shifts attention toward high-profile spectators and could elevate probabilities for U.S.-based celebrities with ties to New York sports or entertainment. Women's semifinal matchups featuring Coco Gauff, Jessica Pegula, Aryna Sabalenka, and Elena Rybakina add further star power to the event. Trader consensus reflects historical patterns of celebrity attendance at Arthur Ashe Stadium for marquee sessions, with schedule positioning and social media signals from potential attendees serving as key variables through the semifinals.
