The launch now means SuperBook is active in six US states, including Arizona, Colorado, New Jersey, Tennessee and Nevada – where it has been operating since 1986.  

SuperBook CEO Mark Lipparelli commented on the launch: "We're excited to bring the SuperBook brand and our decades of experience to the state of Iowa.

“From the Cyclones and Hawkeyes to the Field of Dreams, Iowa has one of the best sports traditions in the country. Many sports fans from Iowa have undoubtedly visited our iconic Las Vegas sportsbook and now they can access those same great betting options from home."

Meanwhile, Jay Kornegay, the VP of Race & Sports Book Operations at SuperBook, further added: "I am excited to launch our sports betting in Iowa. From my time in this business, I've known sports fans in Iowa to be among the most loyal and knowledgeable.

"We're off and running, and we welcome new sign-ups to compare us against the others. We focus on building the best odds anywhere we operate, and we offer several generous odds boosts and other promotional bets."

Iowa has seen several sportsbook operators launch in recent months, with ClutchBet becoming available shortly before the start of the new NHL season in September.

Jake Francis, SVP of Operations at ClutchBet, said of the launch at the time: “Sports fans in Iowa deserve a memorable betting experience, and we are thrilled to make our US debut in a state with an incredibly rich sporting history and a legion of passionate sports fans.”
