Circa Sports also launched online and mobile app betting in Colorado on July 1, 2020, through a partnership with Century Casinos.

Illinois operations were launched on September 29, 2023, via mobile app and a sportsbook, the latter in partnership with Full House Resorts.

By the end of 2015, Stevens was planning to build the Circa Resort, and he believed that the project would give him enough volume to run a sportsbook company.

[4] He filed for licensing to operate his own sportsbooks in September 2018,[6] and received final approval from the Nevada Gaming Commission on April 25, 2019.

[1] Stevens said the books would operate with an "old-school Las Vegas hospitality, where our guests and oddsmakers interact closely in a friendly and fun environment.

[16] Stevens planned to eventually open the brand's flagship sportsbook at the Circa Resort in late 2020.

[1] Operating the two original sportsbooks would help prepare Metcalf and his team for the opening of the main book at the Circa Resort.

[10] During 2020, Circa Sports announced plans to eventually open a sportsbook at the Tuscany casino, near the Las Vegas Strip.

It is a satellite sportsbook, and was opened in time for March Madness,[30][31] during which Circa Sports accepted $10,000 bets.

[39][40] In January 2024, Circa took over sportsbook operations at the Silverton casino in the southwest Las Vegas Valley.

[2][46][47][48] By March 2021, Stevens was planning to expand his online services to Iowa, with several other states also in consideration for future expansion.

[16] Circa's Iowa operations began on October 7, 2021, offering mobile sports betting through a partnership with Wild Rose Casino, which has three locations in the state.

[49][50] In May 2022, Circa partnered with Full House Resorts to open a sportsbook in Waukegan, Illinois, marking its first physical location outside of Nevada.

[51][52] The companies signed an eight-year deal, and Circa would initially operate in a temporary casino while Full House constructs a permanent facility, to be known as American Place.

[56] In May 2024, Circa expanded its mobile app to Kentucky, in partnership with the Cumberland Run horse track in Corbin.

[64] The 2020 contests received fewer entrants due to the pandemic, and Stevens began offering free hotel rooms as an incentive to sign up.
