Dance music star Zedd has been announced as the headliner of the official 2026 U.S. Open Finals Afterparty, taking place on 12 September at New York's Louis Armstrong Stadium, with house producer HoneyLuv also on the bill. The announcement extends the tennis tournament's growing crossover with major electronic music acts, offering fans a marquee entertainment event alongside the on-court action.

It is the third year the tournament has staged a dance afterparty, following Odesza and Tokimonsta last year and Galantis in the first edition. The afterparty runs 12–13 September and requires a separate ticket, with presales opening on 9 July and general sale on 10 July at 10am ET; it will feature expanded grounds access, viewing parties, surprise guests and streamed celebrity arrivals. The Lumineers will play a tournament opening show on 21 August, while the U.S. Open itself runs from 24 August to 13 September at the USTA Billie Jean King National Tennis Center in Flushing, Queens.
