**The 2026 US Open, running August 24–September 13 at Flushing Meadows, features men’s and women’s singles finals on September 12–13 that traditionally draw high-profile attendees including politicians, athletes, musicians, and actors.** Jannik Sinner’s withdrawal due to a right-knee injury and Carlos Alcaraz’s return from a four-month wrist absence after limited match play have shifted attention toward Alexander Zverev (top seed and recent French Open champion) and a deeper American contingent, potentially influencing the event’s star power and spectator interest. Aryna Sabalenka enters as the two-time defending women’s champion amid strong competition from Iga Świątek and Coco Gauff, who arrives with recent hard-court momentum from Cincinnati. Mixed-doubles action has already featured Serena Williams partnering Alcaraz and other notable pairings, adding early buzz that often carries into finals-week attendance. Outdoor hard-court conditions, schedule timing, and any late announcements around player fitness or high-profile guests remain key variables that traders monitor for shifts in implied probabilities around specific attendees.
