Overview Guests come to Wynn Nightlife's Halloween Weekend at Wynn Las Vegas in costume, and the 2026 calendar put The Chainsmokers at Encore Beach Club at Night on Halloween itself, a Saturday, with Hugel the night before. Wynn sets the weekend from October 30 to November 1 and calls it one of the most visually driven nightlife events of the year. Wynn Nightlife is the club division of Wynn Las Vegas, running XS, Encore Beach Club, Intrigue and the Wynn Field Club at Allegiant Stadium. On site The 2026 dates sit at Encore Beach Club at Night, the resort's pool club reopened after dark around its cabanas, bungalows and pools. The 2025 weekend was different. It ran inside XS, where Art of the Wild, Wynn's house and techno party, took all three nights. Intrigue is a third option: its 90-foot waterfall backdrop and the all-vinyl Living Room next door host brand-built nights such as watch parties and brunches. Talent and Influencers Hugel, with support from GROSSOMODDO, and The Chainsmokers were on the 2026 Halloween calendar at EBC at Night. Art of the Wild held XS for Halloween weekend in 2025. Across its venues Wynn lists guests including The Chainsmokers, Marshmello, Diplo, Kylie Jenner and Kim Kardashian. Brand presence Costumes drive the pitch. Wynn's calendar puts partners inside the costume, fashion and social media conversation with an influencer costume competition, branded photo moments and content capture through the weekend. On top of that a partner can take over a venue or brand a VIP area, build an entry installation or put its logo on the red carpet, and Wynn shoots the weekend with its own photo and video crews.
