By 2012, both the Mohegan Sun and nearby competitor Foxwoods Resort Casino (owned by the Mashantucket Pequot) were deeply in debt.

The three companies formed Trading Cove Associates (TCA), which provided the Mohegans with financial support, tribal attorneys, and advisers to assist in the tribe's effort to gain official recognition as a people.

[12] Both Mohegan Sun and Foxwoods were major sources of the rise in unemployment in Connecticut during the pandemic, due to thousands of employees being furloughed or laid off.

[13] Although June 1, 2020, was set as a reopening date for both Mohegan Sun and Foxwoods, Governor Ned Lamont expressed concern that the nation's halting progress in fighting the pandemic did not yet warrant such freedoms from mitigation as take place in bars and casinos and discouraged the tribes from reopening the venues.

The expansion included the "Casino of the Wind," which opened in August 2008 and features 650 slot machines, 28 table games, and 42-table poker room.

[22] However, in September 2008, Mohegan Sun placed the Project Horizon expansion on hold, due to the economic recession affecting the regional gaming markets.

Expansion plans were once again announced on June 24, 2013, for a $50 million, 200,000-square foot "Downtown District," to be built next to the Uncasville casino's Winter Garage, featuring a New England-themed food pavilion; a 14-screen Marquee Cinemas multiplex; an upscale bowling-and-dining facility; and a promenade of retail shops whose tenants will include Coach, Tiffany, Sephora, Tommy Bahama, Puma and others.

At the time, they had plans to build a retail center and it was unknown if a casino or any type of gaming would be allowed to occur.

[28] A month later on September 17, 2007, Massachusetts Governor Deval Patrick unveiled a proposal to license three full-scale casinos in the state in a bidding process.

[30] In June 2011, House Speaker Robert A. DeLeo said that a bill to legalize casinos would be taken up by state legislators in July pending the outcome of talks with Governor Patrick.

[31] In November 2011, Patrick signed the bill allowing three full-scale casinos and one slot machine parlor in the state.

[33] The Quaboag Hills Chamber of Commerce endorsed the destination resort project and the economic benefits for the region.

[34] Mohegan Sun is also competing for a license to develop and operate a casino resort near Boston at the Suffolk Downs racetrack.

The plans called for about 4,000 slot machines, 100 table games, and a poker room on a 42-acre piece of land in the Revere-side of the property.

The New York casino would consist of a 258-room hotel, a 75,000 square feet (7,000 m2) casino with 2,100 video lottery terminals and up to 450 electronic table game positions, five restaurants, retail space, harness race track, grandstand and simulcast and 10,000 square feet (930 m2) of ballrooms and meeting space.

[40] In August 2012, the tribe announced an agreement to take over management of the Resorts Casino Hotel in Atlantic City, New Jersey.

[43] In December 2018, the tribe signed an agreement with Paramount Pictures to build the world's first Paramount-branded theme park in Inspire Integrated Resort.
