XS

XS is the benchmark Vegas megaclub: roughly 40,000 square feet wrapped around the Encore pool, 13,000 of them indoors under the gold leaf, and a decade-plus run at the top of the national club revenue charts. The circular main room opens through sliding glass onto the pool deck, so on warm nights half the party really is outside.

Wynn Nightlife's 2026 resident roster runs deep — The Chainsmokers, deadmau5, Marshmello, Kaskade, ODESZA, Subtronics, Diplo — and this summer plays out on the outdoor Main Stage format that debuted in May 2026. One big caveat: the indoor room closes in late summer 2026 for its first full renovation since the club opened in 2008. Club nights shift to Encore Beach Club after dark until XS reopens near the end of the year.

Expect flagship pricing and flagship lines — Friday and Saturday queues stretch well past an hour once the guest list closes, and tables carry real gratuity expectations on top of the minimum. This is the splurge night, not the budget one. Sunday Nightswim, the pool-session version that runs late April through September, is the softer way in.
