[12] Due to the stadium's round and dark exterior design, it has also garnered the nickname of "Roomba" because of its resemblance to the automatic vacuum cleaners of the same name.

[16] Allegiant Stadium is a ten-level domed stadium featuring an ETFE roof, silver and black exterior with light-up strips installed by YESCO, a 275-foot (84 m) media mesh video screen facing Interstate 15, and large retractable curtain-like side windows facing the Las Vegas Strip.

[17] The north endzone area in front of the retractable windows contains a large 85-foot (26 m) torch that houses a flame in honor of Al Davis, the late longtime owner of the Raiders.

Unlike the Arizona facility, Allegiant Stadium also has an artificial turf field, which is primarily used for college football games.

[26] Raiders owner Mark Davis visited Las Vegas on January 29, 2015, to tour the site and meet with Sands chairman Sheldon Adelson and other local figures.

On April 1, 2016, Davis met with UNLV officials and toured Sam Boyd Stadium to evaluate whether it could serve as a temporary home for the team.

On April 28, 2016, Davis said he wanted to move the Raiders to Las Vegas and pledged $500 million toward constructing the proposed $1.4-billion domed stadium.

Adelson decided to move ahead with the stadium as an individual investment, pledging $650 million of his personal wealth to the project.

[33] By September, the list was narrowed to two possibilities: the Bali Hai Golf Club, south of Mandalay Bay, and a vacant lot on Russell Road, just west of Interstate 15.

[35] On September 15, 2016, the Southern Nevada Tourism Infrastructure Committee unanimously voted to recommend and approve $750 million for the Las Vegas stadium plan.

[37] In October 2016, Sandoval called a special session of the Nevada Legislature to consider the stadium and other tourism-related proposals.

[38] The funding bill for the stadium was approved by a 16–5 vote in the Senate and by 28–13 in the Assembly, and was signed into law by Sandoval on October 17.

[57][58] The ceremony featured NFL Commissioner Roger Goodell, Raiders owner Mark Davis, his mother Carol Davis, various Raiders legends including Howie Long, Jim Plunkett, Tom Flores and Ray Guy, Las Vegas and Nevada politicians such as Governor Brian Sandoval, Las Vegas Mayor Carolyn Goodman, Clark County Commissioner Steve Sisolak and stadium authority head Steve Hill.

[59] In January, construction crews began blasting caliche rock with dynamite to excavate and create the stadium bowl.

[63] On January 27, 2023, the Raiders announced additional suites would be added on the 100 level sidelines in advance of the 2023 season and in preparation for hosting Super Bowl LVIII in 2024.

[67] The Raiders did not admit spectators at any of their games during the 2020 season "based on our commitment to protect the health of our fans and the entire community".

[68][69] The first event at the stadium was a Monday Night Football game on September 21, 2020, where the Raiders defeated the New Orleans Saints 34–24.

[72] The Raiders played their first game at the stadium with fans in attendance on September 13, 2021, as they defeated the Baltimore Ravens 33–27 in overtime on Monday Night Football.

[77] Don Webb received an additional $40 million at the May 23, 2020, Stadium Authority Board meeting to cover the overages.

Don Webb received another $90 million to cover the extra shifts required to fix the broken truss issue.

[84] The public portion of the funding came from municipal bonds issued by Clark County, backed by the proceeds of a special tax on hotel rooms in the Las Vegas area, which took effect in March 2017.

[88] Proponents instead argued that the public financing would be justified by increased economic activity and tax revenue related to the stadium.

[90][91] A total of $645 million in construction bonds sold out in 90 minutes in April 2018, representing Clark County's contribution to the project beyond room taxes already collected.

[94][95] The inaugural game was expected to be held in 2020, but that year's edition of the Las Vegas Bowl was cancelled due to the COVID-19 pandemic.

Allegiant Stadium hosted Super Bowl LVIII between the Kansas City Chiefs and San Francisco 49ers on February 11, 2024, as well as Usher's half time show.

[149] On November 22, 2022, the NCAA Division I Men's Basketball Committee selected the stadium to host Las Vegas' first Final Four and National Championship games on April 1–3, 2028.
