Michelob Ultra Arena

The Michelob Ultra Arena, formerly the Mandalay Bay Events Center, is a 12,000-seat multi-purpose indoor arena at the Mandalay Bay Resort and Casino, located on the Las Vegas Strip in Paradise, Nevada. It is owned and operated by MGM Resorts International, and was opened on April 10, 1999. MGM and brewing company Anheuser-Busch entered a naming-rights agreement in 2021, naming the arena after the company's Michelob Ultra beer.

It is the home arena for the Las Vegas Aces of the Women's National Basketball Association and was previously home to the Las Vegas Desert Dogs of the National Lacrosse League. The arena also hosts a variety of music, sports, and entertainment events.

The facility opened as the Mandalay Bay Events Center on April 10, 1999, with a performance by opera singer Luciano Pavarotti, appearing in his first Las Vegas concert since 1985. The facility opened a month after the Mandalay Bay resort, and included a 30,218 sq ft (2,807.3 m²) floor. The venue was originally planned to include 8,000 seats, but boxing promoter Bob Arum convinced Mandalay Resort Group to increase this to 12,000. The Mandalay Bay Events Center gave Las Vegas its third musical arena, joining the Thomas & Mack Center and the MGM Grand Garden Arena.

MGM Mirage acquired Mandalay Resort Group and the venue in 2005, and was later renamed MGM Resorts International. Around 2014, MGM considered turning the facility into a theater, before deciding to build the Park Theater (now known as "Dolby Live") instead. In February 2021, the venue was renamed Michelob Ultra Arena, through a partnership with brewing company Anheuser-Busch. It is named after the company's Michelob Ultra beer.

The arena hosts boxing matches, including the high-profile Amir Khan vs. Zab Judah Light welterweight title unification, match on July 23, 2011.

As of July 2018, the Mandalay Bay Events Center has held 31 Ultimate Fighting Championship (UFC) events, starting with UFC 33, and most recently, UFC Fight Night 88. It held the largest UFC weigh-in show in history in conjunction with International Fight Week 2012 ahead of UFC 148 welcoming 10,000 fans. UFC cards in Vegas have since moved to T-Mobile Arena as part of a comprehensive marketing and tenancy agreement.

The 999th episode of WWE Raw was held at the arena on July 16, 2012, the first time the WWE performed at Mandalay Bay.

The Las Vegas Aces are the primary long-term tenant of the arena. The NBA and WNBA officially announced on October 17, 2017, that the San Antonio Stars would relocate from San Antonio, Texas, and would be playing at the Mandalay Bay Events Center starting in the 2018 season as the Las Vegas Aces. They played their first home game on May 27, 2018. The arena has hosted the Aces in the WNBA Finals twice, in 2022 and 2023. The Aces have four banners hanging from the rafters at the arena: one for the retirement of Becky Hammon's number 25, two for their WNBA championships in 2022 and 2023, and one for their 2022 Commissioner's Cup championship.
