Background and early ventures (1969–1988) The company's background can be traced to 1969, when airline and casino tycoon
Kirk Kerkorian bought a controlling stake in the
Metro-Goldwyn-Mayer (MGM) film studio. In 1970 and 1971, Kerkorian struggled with debt from his acquisitions of MGM and
Western Airlines, and was forced to sell a majority of his casino company, International Leisure, to
Hilton Hotels at a steep discount. When the
Las Vegas Hilton, the casino he had built, subsequently became the most successful hotel in Las Vegas, Kerkorian was inspired to lead the studio into the gambling industry. The
MGM Grand Reno followed in 1978. By 1979, the two hotel-casinos accounted for most of MGM's income, and the company announced a plan to split itself in two. The next year, the film studio was
spun off as a new company, while the original company, renamed as MGM Grand Hotels Inc., retained the two hotel-casinos. Kerkorian held a 47 percent stake in both companies. A deal was reached for
Bally Manufacturing to buy the company; the deal closed in April 1986, and the two casinos were renamed under the Bally's brand. The terms of the sale allowed Kerkorian to retain rights to the MGM Grand name, and plans were announced to offer the stockholders of MGM Grand Hotels shares in a new company that would hold the naming rights. The company now known as MGM Resorts International was formed in 1986 as
Grand Name Co. as a subsidiary of Kerkorian's
Tracinda Corporation. It was renamed in 1987 as
MGM Grand, Inc. The company also made an offer to take over financially struggling
Pan American World Airways, but this offer was rejected by Pan Am's board in November 1987. In August 1987, MGM Grand bid $152 million for the bankrupt
Dunes Hotel in Las Vegas, but was beat out by Japanese billionaire
Masao Nangaku. Instead, the company acquired the
Desert Inn and
Sands casinos in February 1988 from
Summa Corporation for $167 million. The Sands was sold to
Sheldon Adelson's Interface Group for $110 million in April 1989.
First casino developments (1989–1999) In September 1989, the company announced plans for a $700-million Hollywood-themed complex, including a 4,000-room hotel and a theme park. The Desert Inn site was initially considered as a location for the project, which MGM Grand acquired for $93 million plus $30 million in stock. The company put the Desert Inn up for sale to focus efforts on the new project, but found no outside bidders, and agreed to sell it to Tracinda for $130 million. Construction on the
MGM Grand Las Vegas and the
MGM Grand Adventures theme park began in October 1991, and the property opened in December 1993 at a final cost of $1 billion. The park permanently closed in 2002 due to a lack of interest. The company moved its headquarters from Beverly Hills to Las Vegas in July 1992. During construction of the MGM Grand, the company acquired an option to buy an 18-acre site across the street from the project.
Gary Primm of
Primadonna Resorts approached MGM president Bob Maxey in 1994 with an idea for the site: a casino recreating the New York skyline. A joint venture was formed between the two companies, and construction began in March 1995. Completed at a cost of $460 million, the
New York-New York Hotel and Casino opened in January 1997. With New York-New York under development, MGM Grand made moves to expand in several other markets. An exploratory agreement to develop two casinos on the Chinese island of
Hainan was announced in August 1994, but came to nothing. In
Darwin, Australia, a lucrative market attracting high rollers from Pacific Rim countries, the company considered building a hotel, but instead bought the
Diamond Beach Hotel and Casino, renaming it as the MGM Grand Darwin. MGM announced plans for an
Atlantic City casino in July 1996. In Michigan, where voters approved casinos in November 1996, MGM made plans for a bid on one of the three available gambling licenses, which would eventually be approved and open in July 1999 as the
MGM Grand Detroit. In South Africa, with casino gambling newly authorized, MGM announced plans in August 1996 to develop 15 properties in conjunction with
Tsogo Sun. The first, a temporary casino in
Johannesburg's
Sundome, opened in October 1998. Three more casinos followed before MGM agreed to sell out its interest in the properties to Tsogo Sun in November 2001. Since the initiation of New York-New York, analysts had speculated that MGM Grand or Primadonna would buy out the other's interest in the project. Instead of making such a cash-intensive purchase, however, MGM agreed to buy Primadonna outright for $276 million in stock plus $336 million in assumed debt. The merger closed in March 1999, giving MGM ownership of three casinos and two golf courses at the Nevada–California state line, in addition to full control of New York-New York.
Mirage Resorts merger (2000) In February 2000, MGM Grand made an unsolicited offer of $17 a share to buy
Mirage Resorts, which had floundered due to disappointing results at its new
Beau Rivage and
Bellagio resorts. Analysts expected a protracted battle, with Mirage founder
Steve Wynn seen as unwilling to give up control but under pressure from institutional investors. Mirage rejected the offer, but Wynn met with Kerkorian the next day and named a price of $21 a share. The companies agreed on the higher price, for a total of $4.4 billion plus $2 billion in assumed debt. The merger closed in May 2000, giving MGM ownership of the
Mirage,
Treasure Island, Bellagio,
Boardwalk, and
Golden Nugget casinos in Las Vegas, the
Golden Nugget in Laughlin, and the Beau Rivage in Mississippi, and a half share of the
Monte Carlo. The company changed its name to MGM Mirage in August 2000. Mirage had also owned a half stake in the
Borgata, a planned casino in Atlantic City, in a joint venture managed by
Boyd Gaming. Work on the Borgata continued apace, and it would open in July 2003.
Stalled developments (2001–2004) In 2001 and 2002, following the merger with Mirage, the company explored options for its next major development project, including in the
Las Vegas,
Atlantic City,
Chicago, and
Macau markets. The 55-acre site of the Boardwalk casino on the Las Vegas Strip was earmarked for a technologically advanced megaresort targeting a
Generation X demographic. In Atlantic City, MGM shifted focus from its previously announced boardwalk site to a proposed billion-dollar hotel and casino on a 55-acre tract adjacent to the Borgata, where Wynn had planned to build the Le Jardin casino. In the Chicago market, MGM agreed to pay $600 million to buy the unfinished Emerald Casino in
Rosemont, Illinois, whose investors had been accused of ties to organized crime. The deal was rejected, however, by state gambling regulators, and MGM then backed off its effort, saying that Illinois's casino tax was too high. In Macau, where
Stanley Ho's 40-year government-granted monopoly on gambling was coming to an end, MGM submitted a bid for one of three available gambling concessions, but it was not selected, losing out to Ho,
Las Vegas Sands, and
Wynn Resorts. MGM made moves into the United Kingdom market after a 2001 government report called for loosening of the country's gambling regulations. It opened an online casino, playmgmmirage.com, licensed in the
Isle of Man, a British dependency, and it applied for a license to run an online sports betting site in the U.K. It acquired a twenty-five percent stake in a company developing the small Triangle Casino in
Bristol, It signed deals to build casinos at the
Olympia Exhibition Centre in London,
St James' Park in Newcastle,
Meadowhall Shopping Centre in Sheffield, the
National Exhibition Centre in Birmingham,
Sportcity in Manchester,
Glasgow Harbour,
King's Waterfront in Liverpool, and at a proposed stadium in
Salford. The company also signed a $490-million deal to acquire Wembley plc, owner of seven
greyhound tracks in Britain and four in the United States. The British expansion plans ultimately amounted to nothing. MGM closed its online casino after less than two years, citing uncertainty in American regulations and competition from established British brands. The Wembley acquisition turned into a bidding war, with MGM finally losing out to an investors group including Kerzner International. The Triangle Casino was sold off to
Stanley Leisure in 2006. The company's other development plans were scuttled as the government scaled down, and eventually abandoned, the plan to allow large "
super-casinos". In 2004, the company disposed of some of its smaller properties, selling the two Golden Nugget casinos (
Golden Nugget Las Vegas and
Golden Nugget Laughlin) to
Poster Financial Group for $215 million, and the
MGM Grand Darwin to
Skycity Entertainment for $140 million.
Mandalay merger (2004–2005) MGM entered into quiet merger talks with
Mandalay Resort Group in early 2004. The potential acquisition would give MGM control of more than half the hotel rooms on the Las Vegas Strip. Mandalay assets attractive to MGM included low-end casinos like
Excalibur and
Circus Circus to broaden MGM's "high roller" appeal; the
Mandalay Bay Convention Center, which would allow MGM to compete directly with the
Sands Expo center in the convention market; The talks went public in June, when MGM announced an offer worth $7.65 billion. Mandalay rejected that offer because of a clause allowing MGM to back out if
antitrust regulators demanded the sale of any properties. MGM executives were confident that antitrust regulators would not require the sale of any of the two companies' properties. Michigan law, however, forbade one company from owning multiple casinos, requiring the sale of either the MGM Grand Detroit or Mandalay's 54 percent stake in the
MotorCity Casino. After some vacillation about which property to sell, Mandalay accepted a $525-million offer for its interest in MotorCity from
Marian Ilitch, the casino's second largest shareholder. Meanwhile, in Illinois, where MGM needed regulatory approval to take over Mandalay's 50 percent interest in the
Grand Victoria Casino, a lack of
quorum on the state Gaming Board threatened to delay the merger. MGM considered a sale to the casino's other owner, the
Pritzker family, but ultimately gained approval for a plan to place the property under control of a
trustee until completion of the licensing process. The FTC approved the merger as predicted, and MGM obtained a $7 billion
line of credit to finance it. The sale closed on April 25, 2005 for a total of $7.9 billion, including $3 billion in assumed debt. The Mandalay acquisition made MGM Mirage the largest gambling company in the world, in a deal that had been spurred on by news of the MGM-Mandalay merger.
Later developments (2004–2006) Despite MGM's initial failure to win a gambling concession in Macau, the company had remained interested in the burgeoning gambling market. Rumors of a possible partnership with Stanley Ho were reported in 2003, but Nevada gambling regulators informally vetoed the idea because of the alleged involvement of organized crime
triads in his casinos. Another possibility emerged when the government allowed the three gaming concessionaires to each sell a sub-concession. In June 2004, MGM formed a joint venture with
Pansy Ho, Stanley's daughter, to develop a casino-hotel under a sub-concession from Stanley. Despite initial concerns about whether Pansy Ho was subject to her father's influence, the
Nevada Gaming Commission eventually approved the partnership. Construction of the
MGM Grand Macau began in June 2005. The property opened in December 2007, completed at a cost of $1.25 billion. In 2004, MGM solidified its plans for the Boardwalk site on the Strip, announcing
Project CityCenter, an $8-billion high-density project including hotels, condominiums, a casino, and a shopping mall. The Boardwalk was closed in January 2006 to make way for the redevelopment, and CityCenter construction began the following June.
Singapore emerged in 2004 as the next major new Asian gambling market, calling for proposals to build two "
integrated resort" casinos at
Marina Bay and the island of
Sentosa. MGM partnered with
CapitaLand in an estimated $3 billion bid for the Marina Bay site. The government awarded the license, however, to
Las Vegas Sands, citing its strength in the
meetings and conventions sector. In 2007, MGM Mirage disposed of some outlying properties in Southern Nevada. The two
Laughlin casinos (the
Colorado Belle and
Edgewater) were sold for $200 million, the
Primm Valley Resorts were sold for $400 million, and the
Nevada Landing Hotel and Casino was closed.
Dubai World investment (2007–2009) On April 19, 2007 the company announced that it planned to purchase a site from Concord Wilshire Partners for $130 million and a site from Gordon Gaming for $444 million. The two parcels give the company complete control of the southwest corner of the Sahara and Las Vegas Boulevard intersection. When combined with underused parts of the
Circus Circus site, the company will have a site for future development. The Concord site had been the proposed location for the
Maxim Casino. On August 22, 2007,
Dubai World said it would buy a 9.5 percent stake in MGM for about $2.4 billion. It would also invest about $2.7 billion to acquire a 50 percent stake in MGM's CityCenter project. Dubai World would pay MGM Mirage an additional $100 million if the project opened on time and on budget. The investment firm would buy 14.2 million shares from MGM Mirage. The firm would also issue a public tender for an additional 14.2 million shares at the same price. In October 2008, MGM Mirage halted a $5 billion Atlantic City project on land next to the Borgata. At about the same time, New Jersey gambling regulators were evaluating MGM Mirage's suitability to operate casinos in New Jersey, and were unconvinced that MGM Mirage's Macau partner, Pansy Ho, could operate independently from influence of her father, Stanley Ho. The latter was often accused of ties with Chinese organized crime and letting the gangs operate in his casinos' VIP rooms. Faced with not complying with New Jersey gambling regulations, MGM Mirage decided to divest the highly profitable Borgata in order to continue pursuing the even more lucrative Chinese market. MGM Mirage subsequently transferred its 50% share in the Borgata to a divestiture trust through which it received all benefit of the ownership. The trust was responsible for selling MGM's interest within 30 months, although MGM had the right to direct the trustee during the first 18 months. In December 2008, MGM Mirage announced the sale of its Las Vegas
Treasure Island resort and casino to billionaire
Phil Ruffin. The sale was completed on March 20, 2009 for $600 million in cash plus a $175 million promissory note. In March 2009, Dubai World and Infinity World announced that they had filed a lawsuit in the Delaware Chancery Court seeking to be released from their CityCenter joint venture agreement with MGM Mirage after the company filed its annual report stating that "there is substantial doubt about our ability to continue as a going concern," and "it cannot provide assurance that its business would generate sufficient cash flow from operation." Starting in April 2009, news reports surfaced that MGM Mirage had hired investment firm
Morgan Stanley to assist the company in finding possible buyers for the MGM Grand Detroit and the Beau Rivage.
Name change and recent years (2010–present) In June 2010, MGM Mirage changed its name to "MGM Resorts International", to emphasize the brand's global scope and increased non-gambling strategy. In May 2011, an
initial public offering was held for the MGM Macau property through a new holding company, MGM China. MGM retained a 51 percent interest in the company, with Pansy Ho holding a 29 percent stake, and 20 percent sold to public investors for $1.5 billion. In January 2013, MGM China received government approval to build its second resort in Macau. In 2013, MGM won state licenses to build a
$1-billion resort in
National Harbor, Maryland and
a $950-million resort in downtown
Springfield, Massachusetts. In May 2014, the company broke ground on the $375-million
T-Mobile Arena located behind New-New York Hotel and Casino, in partnership with
AEG Live. The arena opened on April 6, 2016. MGM sold several properties in 2015, including the
Railroad Pass Casino, the
Gold Strike, and properties in
Reno (
Circus Circus Reno and a 50 percent stake in the
Silver Legacy) were sold to
Eldorado Resorts for $72.5 million. In April 2016, MGM sold
The Shops at Crystals, the high-end mall in CityCenter, to Invesco Real Estate and Simon Property Group for $1.1 billion. In April 2016, MGM held an initial public offering for
MGM Growth Properties (MGP), a new
real estate investment trust (REIT) with ownership of ten of the company's casinos; the parent company would continue to operate the casinos under a lease agreement. The offering raised $1.05 billion, and left MGM Resorts with 76 percent ownership of the REIT. In August 2016, MGM bought out Boyd Gaming's interest in the Borgata for $900 million, and then sold the property to MGP for $1.2 billion and leased it back for $100 million per year. In 2017, MGM launched two online ventures under the PlayMGM brand: an online sportsbook in Nevada, and an online casino in New Jersey. In October 2017, MGM purchased the
San Antonio Stars of the
Women's National Basketball Association. The team was moved to
Mandalay Bay Events Center and began play as the
Las Vegas Aces in 2018. In August 2018, MGM and Hyatt sold the Grand Victoria Casino to Eldorado Resorts for $328 million. In January 2019, MGM bought
Yonkers Raceway and Empire City Casino in New York from the
Rooney family for $850 million, and then immediately sold the land and buildings to MGP for $625 million, and leased them back for $50 million per year. MGM Resorts is bidding to secure a full casino license for their Empire City Casino which would allow for table games. If awarded a casino license, they will also expand the casino and add new amenities. The community advisory committee voted 5-0 in favor of the proposed development on September 25, 2025. This vote advances MGM’s bid to be considered for a full casino license in New York. In 2019, MGM sold two resorts on the Las Vegas strip: Bellagio and Circus Circus. They sold their real estate assets of Bellagio to
Blackstone Group while selling Circus Circus to Phil Ruffin. In 2020, they sold their real estate assets of MGM Grand and Mandalay Bay to a joint venture between Blackstone and MGP. In 2021, MGM bought 50% of Dubai World's share of CityCenter and sold the real estate assets of
Aria and
Vdara to Blackstone and later purchased the operating assets of
Cosmopolitan of Las Vegas and later sold the Mirage to
Hard Rock International. Also in 2021, MGM would sell the Las Vegas Aces to
Mark Davis, owner of the
Las Vegas Raiders. MGM is looking to secure a casino license in the
United Arab Emirates in order to operate a casino at their upcoming property in
Dubai which is set to open in 2028. So far, only
Wynn Resorts has secured a gambling license in the country.
Response to the COVID-19 pandemic In August 2020, MGM cut 18,000 job positions as a result of the effects of the
COVID-19 pandemic. The job cuts represent one fourth of its workforce, which before the start of the pandemic was 68,000.
Attempts to block tribal casino developments MGM lobbied the Trump administration against giving federal approval for a casino operated by two native tribes in East Windsor, Connecticut. The casino would have provided competition to a MGM casino across the border in Massachusetts. The new partnership will see four of MGM's properties fully affiliated with Marriott brands beginning in late 2023. The Bellagio will join The Luxury Collection division of Marriott, the Park MGM will join Marriott's
Tribute Portfolio, and the Aria will join Marriott's Autograph Collection, which The Cosmopolitan has been a member of since its opening.
Cyber attacks A data breach in 2019 affected 10.6 million previous customers, with about 1300 individual's having identification numbers exposed.In September 2023, MGM's hotel and casino operations were disrupted for several days during a
cybersecurity attack by the hacking group
Scattered Spider. The company refused to pay a ransom to the hackers, and stated that its losses of $100 million would be covered by
cyber insurance. As a result of the cyberattack, multiple
class action lawsuits were filed against MGM Resorts as well as
Caesars Entertainment, which Scattered Spider had hacked into during the same month, with all stating that the failure for both of the casino operators to adequately secure their data constituted breach of contract. Hackers Scattered Spider later formed a
cybercrime collective with
ShinyHunters and
Lapsus$ in 2025. Both the 2019 and 2023 class action lawsuits were settled together for $45 million on June 18, 2025.
Escape Solar + Storage In September 2024, the company contracted with Escape Solar for the Escape Solar + Storage project, to be operated by Estuary Power. The $340 million solar facility will help power Las Vegas Strip casinos, with more than 60% of its battery energy storage planned for MGM Resorts International casinos.
MGM Osaka In April 2025, MGM Resorts broke ground on
MGM Osaka, which will be the first integrated resort and casino in
Japan. It is set to open in 2030.
NGCB fine Nevada Gaming Control Board (NGCB) unanimously voted, on April 24, 2025, to levy a fine of $8.5 million on the company for having allowed two illegal
bookmakers to gamble at
MGM Grand and The
Cosmopolitan. The investigation implicated former MGM Grand president Scott Sibella, as facilitating the fraud, between 2017 and 2020. Sibella's gambling license was revoked by the
Nevada Gaming Commission on December 19, 2024. ==MGM Hospitality==
