MGM Resorts International is an American global hospitality and entertainment company operating destination resorts in Las Vegas, Massachusetts, Detroit, Mississippi, Maryland, and New Jersey, including Bellagio, Mandalay Bay, MGM Grand, and Park MGM. In January 2019 the company took over Empire City Casino in Yonkers, New York, and also opened MGM National Harbor in Maryland and MGM Springfield in Massachusetts. The company has a majority interest in MGM China Holdings Limited, which owns the MGM Macau resort and casino, and is developing a gaming resort in Cotai. MGM Resorts owns 50 percent of CityCenter in Las Vegas, which features Aria Resort & Casino. It has a majority controlling interest in MGM Growth Properties, a real estate investment trust.
The company began operations in 1987 as MGM Grand, Inc. and became MGM Mirage in 2000, after acquiring Mirage Resorts. In the mid-2000s, growth of its non-gaming revenue began to outpace gaming receipts and demand for high-rise condominiums was surging, with median property prices in Las Vegas twice the national average. The company shifted its focus from owning and operating resorts and casinos to developing and building real estate in the leisure and gaming industry—launching the massive CityCenter mixed-use project, which was at the time of its construction the world's largest construction site and ranks as one of the most expensive real estate projects in history. City Center's development coincided with the global financial crisis, causing more than $1 billion in writedowns in its valuation.
