Rosemont is a village in Cook County, Illinois, United States, located immediately northwest of Chicago.

Due to its location, much of the village is occupied by a large highway interchange, hotels, and office buildings.

[11] According to Colliers International, the Rosemont/O'Hare office market encompassed approximately 13.325 million square feet (1,237,900 m2) of total inventory in Q1 2017.

Among these are the Donald E. Stephens Convention Center, used for trade shows and gatherings; the Rosemont Theater, used for award ceremonies and concerts; and the Allstate Arena, used for concerts, professional wrestling (three times hosting WrestleMania), Chicago Wolves hockey, and formerly the DePaul Blue Demons basketball program and Chicago Sky WNBA basketball.

Starting in 2011, the Chicago Bandits women's National Pro Fastpitch team moved to Rosemont after playing in Elgin and Lisle in the past.

When the Bruisers advanced to the league championship in 1988, Rosemont hosted ArenaBowl II, as well as an arena football test game in 1987.

[18] The team is part of the American Association of Independent Professional Baseball and play in a 6,300-seat ballpark, Impact Field.

[22] In 2017, village trustees voted to increase Stephens' salary by 53 percent to $260,000, making him one of the highest paid mayors in the United States.

[22] The Chicago Tribune has reported that the village was "renowned for insider dealing", acting as a legal mechanism to funnel money to the Stephens family.

[23] Throughout the 2000s, at least four other members of the Stephens family held highly paid managerial positions in city institutions such as the convention center, parks, and public safety.

[22] Mark Stephens, the mayor's brother, owns a private company called Bomark which holds a $4.5 million annual contract to handle parking and other public functions.

[3][23] In a 2023 article,The Economist described the village as "the last true political machine in America" and likened it to autocratic states like Gabon.

[25][26] However, the Illinois Gaming Board eventually withdrew the license in 2001 after concern about close ties to the Chicago Outfit mafia.

[26] An FBI agent testified that Stephens had met with Joey Lombardo and John DiFronzo, among others, to divide up contracts for casino work.
