T-Mobile Arena opened on April 6, 2016, on the Las Vegas Strip in Paradise, Nevada, as a $375 million joint venture between MGM Resorts International and Anschutz Entertainment Group (AEG). Situated steps behind the New York-New York and Park MGM casino hotels, the arena established itself almost immediately as one of the most coveted concert destinations in North America.
Designed by architecture firm Populous and nicknamed ‘The Fortress,’ the venue was grand-opened with a performance by Las Vegas natives The Killers alongside Shamir and Wayne Newton. Since that debut, it has welcomed some of the world’s biggest touring artists, served as the televised home of marquee award shows, and is now positioning itself as the likely first home for Las Vegas’s incoming NBA expansion franchise.
Quick Answer: T-Mobile Arena Capacity
T-Mobile Arena holds up to 20,000 fans for concerts, boxing, and UFC events, 18,000 for basketball, and 17,500 for Vegas Golden Knights hockey games. Concert capacity flexes with the show: end-stage productions typically seat 12,000-18,000, while full center-stage, arena-in-the-round tours can push attendance to 19,500-20,000.
The arena sits at 3780 S. Las Vegas Blvd. on the Las Vegas Strip, directly behind New York-New York and Park MGM, making it one of the most walkable large-capacity venues on the Strip.
T-Mobile Arena Capacity By Event Type
T-Mobile Arena’s bowl is designed to reconfigure for whatever is on stage or on the ice, which is why you’ll see different capacity numbers depending on the event. For concerts, an end-stage setup — the standard configuration for most touring artists — seats roughly 12,000 to 18,000, while a center-stage, in-the-round show can expand to the arena’s full 19,500-20,000-seat capacity, including floor standing room for the largest tours.
For Vegas Golden Knights hockey, the arena is configured for about 17,500 seats. Basketball events, including college tournaments, WNBA games, and the NBA Cup semifinals and championship the arena has hosted in recent years, typically seat around 18,000. Boxing, UFC, and other combat-sports cards use the arena’s largest footprint, seating up to 20,000 — the same ceiling used for the biggest award shows and residencies.
Where Is T-Mobile Arena?
T-Mobile Arena is located at 3780 S. Las Vegas Blvd., Las Vegas, NV 89109, on a 16-acre site set back from the Strip between New York-New York and Park MGM, near the corner of Las Vegas Boulevard and Park Avenue. It’s an easy walk from most Strip resorts and is served by the Las Vegas Monorail and rideshare drop-off zones near the adjacent Toshiba Plaza.
Because the arena is tucked behind the casino frontage rather than facing the Strip directly, first-time visitors sometimes miss the entrance — the official site’s directions and parking guidance are the most reliable way to plan a route: the official T-Mobile Arena website.
How T-Mobile Arena Compares to Other Las Vegas Arenas
Las Vegas concert venue capacity spans a wide range, and T-Mobile Arena sits at the top of the mid-size tier. Michelob ULTRA Arena at Mandalay Bay, home of the WNBA’s Las Vegas Aces, seats about 12,000. UNLV’s Thomas & Mack Center, the city’s other major indoor arena, runs from roughly 14,700 for end-stage concerts up to about 18,600 for boxing. The Sphere, Las Vegas’s newest large-scale venue, seats around 18,000 in its immersive, non-traditional bowl.
At the opposite extreme, Allegiant Stadium, home of the Las Vegas Raiders, holds around 65,000 for football and can expand past 70,000 for stadium-scale concert tours. That makes T-Mobile Arena the city’s go-to option for artists who’ve outgrown a casino showroom or Michelob ULTRA Arena’s 12,000 seats but don’t need a full stadium run. As an indoor arena in Las Vegas purpose-built for both major-tour acoustics and championship-level sports, it occupies a lane no other Strip venue directly competes in.
The Concert Experience
The sightlines and acoustics — engineered by Populous with high-volume entertainment in mind — have made the venue a consistent stop for major tours, hosting performers including Lady Gaga, The Rolling Stones, BTS, and Justin Timberlake. Country music found an especially prominent home here when George Strait launched his celebrated ‘Strait to Vegas’ residency at the arena, drawing fans from across the country to the Las Vegas Strip.
The Academy of Country Music Awards has used the T-Mobile stage for its nationally televised broadcast on multiple occasions, and the arena has also hosted the Billboard Music Awards, the iHeartRadio Music Festival, and the Latin Grammy Awards — cementing its status as a destination for high-profile music events rather than just a generic concert stop.
Could T-Mobile Arena Become an NBA Arena? The Expansion Angle
The NBA’s Board of Governors has moved to formally explore league expansion for the first time in decades, with Las Vegas and Seattle the two front-running markets. The earliest an expansion franchise could tip off is the 2028-29 season, with reported expansion fees around $6 billion per team. Two rival ownership groups are competing for the Las Vegas franchise: one led by Vegas Golden Knights founder Bill Foley, and another headed by former Phoenix Suns owner Jerry Colangelo, operating under the name ‘Las Vegas Jacks.’
MGM Resorts president and CEO Bill Hornbuckle has said publicly that ‘all roads lead to’ T-Mobile Arena as the team’s likely first home, since a 2028 launch wouldn’t leave enough time to build a dedicated new arena from scratch. T-Mobile Arena already has a basketball track record to lean on — it has hosted the semifinals and championship game of the NBA’s in-season tournament (now the NBA Cup) in 2023, 2024, and 2025. A separate proposal, the privately pitched ‘Diamond Arena,’ has also surfaced as a from-scratch alternative — a planned 21,212-seat basketball-specific venue near Mandalay Bay and Four Seasons Drive — but as of 2026 it remains unbuilt and unfunded, while T-Mobile Arena is already standing and operational. Whether the eventual franchise plays at T-Mobile Arena permanently or just as a bridge venue while a new arena is built, it remains the front-runner to host Las Vegas’s first NBA team.
Ownership and Las Vegas Strip Setting
The arena is owned by a consortium consisting of AEG (42.5%), MGM Resorts International (42.5%), and Vegas Golden Knights founder Bill Foley (15%), with MGM Resorts handling day-to-day operations. Its position at 3780 South Las Vegas Boulevard places concertgoers steps from the restaurants, hotels, and entertainment options lining the Strip, making a night at T-Mobile Arena easy to fold into a broader Las Vegas experience.
Beyond music, the venue serves as the home rink of the Vegas Golden Knights NHL franchise and hosted games during both the 2018 and 2023 Stanley Cup Finals — the latter ending with Las Vegas claiming its first championship. That dual identity as a major sports landmark and a world-class music venue makes T-Mobile Arena one of the most versatile large-capacity rooms in the country.
