continued with its plans to operate a Grand Hyatt. In April 2009, the Sun reported that the hotel would be managed by Hilton and would become the Hilton's first in their new Denizen hotel line. Later that month, however, those plans changed; Starwood sued Hilton, claiming trade-secret theft and essentially killing the Denizen brand. In June 2009, 400 homebuyers filed a lawsuit against the developers, claiming breach of contract and seeking refunds for their deposits. They believed that the projected finish date of June 2010 was unrealistic and expressed fear that the developers might turn the condo rooms into hotel rooms only or "finish the building as a shell and not do any interior work." In April 2010, it was announced that the Cosmopolitan would open in stages, beginning in December and ending in July 2011. It was the only hotel-casino to open on the Strip in 2010. The project officially opened on December 15, 2010, and became part of Marriott International's Autograph Collection, a collection of independent hotels with access to Marriott's reservation and rewards system. In January 2014, the Cosmopolitan announced that points through their Identity rewards program could be redeemed at 3,800 of Marriott's properties. In May 2014, the Cosmopolitan was sold by Deutsche Bank to Blackstone Group for $1.73 billion.

Two people were treated for smoke inhalation as a result of the blaze, including one person who was transported to a local hospital. Investigators could not conclusively determine a cause for the fire, but suspected that guests had dropped burning cigarette butts from balconies onto outdoor furniture below. In September 2021, the casino was sold to MGM Resorts International.

The acquisition was completed on May 17, 2022. Restaurants In March 2010, the casino announced several celebrity chefs and restaurants that would open there. Included were Bruce and Eric Bromberg's Blue Ribbon, Costas Spiliadis' Estiatorio Milos (which has since relocated to the Venetian), Scott Conant's Scarpetta, and David Myers' Comme Ça, which has been shuttered and replaced with other dining options. On May 2, the resort announced that José Andrés would be joining the resort with
