Halloween 2026 already has a confirmed Strip party lineup. Marquee at The Cosmopolitan of Las Vegas has posted its Dawn 2 Dusk program for Friday and Saturday, Oct. 30 and 31, with four DJ performances split between the dayclub and nightclub.
NOTD is scheduled for the dayclub on Friday, followed by Illenium at the nightclub that night. On Saturday, Martin Garrix is listed for the dayclub and Steve Aoki for the nightclub. The event is billed as 48 hours of Halloween at Marquee, giving partygoers a two-day, two-night option on a Saturday Halloween weekend.
One important distinction: these are seasonal events at existing venues, not new venue openings. The event listings confirm Marquee’s Halloween plans, not a complete Strip-wide calendar. Vegas will keep adding dates to its party map, but this is a confirmed place to start.
What Marquee has scheduled for Halloween weekend
The four performances appear under the Dawn 2 Dusk Halloween Weekend banner on Marquee’s official event page. The program uses both Marquee Dayclub and Marquee Nightclub at The Cosmopolitan.
Friday, Oct. 30
- Marquee Dayclub: NOTD.
- Marquee Nightclub: Illenium.
Saturday, Oct. 31
- Marquee Dayclub: Martin Garrix.
- Marquee Nightclub: Steve Aoki.
The official listings identify the dates, performers and venues, and provide ticket and VIP reservation links. They do not give a single price that applies to every ticket or reservation. Check the event page for current availability and terms before making plans.
What the announcement means for Strip plans
Halloween falls on Saturday in 2026, and Marquee’s schedule covers both the holiday and the preceding Friday. The dayclub and nightclub programs are separate events, so a plan for one does not automatically include admission to the other. Read each event’s ticket details carefully.
Marquee is inside The Cosmopolitan, on the Strip. Its lineup gives visitors a specific option for the weekend, but it should not be mistaken for a full directory of Las Vegas Halloween events. More announcements may appear on other resort calendars as the date approaches.
The word “opening” can also send partygoers the wrong way. Marquee is an established venue; Dawn 2 Dusk is its announced Halloween weekend program. The schedule does not announce a newly opened club or attraction.
Check the details before you go
- Choose the right venue: Confirm whether your event is at Marquee Dayclub or Marquee Nightclub.
- Match the date and performer: The dayclub and nightclub have different scheduled acts on both nights.
- Review ticket terms: Check the official event page for current prices, availability, entry instructions and any applicable rules.
For the latest event information, use the Dawn 2 Dusk schedule and the linked ticket pages. The official Marquee venue page at The Cosmopolitan also lists the club’s location.
A confirmed start, not the whole Halloween map
Marquee has put real dates and names on the calendar: NOTD and Illenium on Friday, then Martin Garrix and Steve Aoki on Saturday. That is a solid two-night Strip plan for fans of electronic music, not proof that every resort has announced its Halloween events.
Before booking the rest of the night, check each venue’s own listing. In Las Vegas, the details are the difference between a fun Halloween itinerary and a costume with nowhere to go.
