Rush Street Interactive Fully Launches BetRivers Online Sportsbook in Arizona

RSI Now Operates Real-Money Gaming in Twelve States

Rush Street Interactive, Inc. (NYSE: RSI) ("RSI"), a leading online sports betting and casino company in the United States, today announced that its award-winning BetRivers online sportsbook is fully launched in Arizona. Sports fans aged 21 and over can now register, deposit funds, wager, and withdraw payouts quickly and securely from the BetRivers Sportsbook app for iOS and Android.

The BetRivers online sportsbook offers thousands of betting options on various leagues, games, and players, as well as other innovative features including betting tips, an advanced stats center and player search functionality, a wide library of live streaming content and real time game tracker visualizations. RSI’s mobile sportsbook app was recently rated #3 out of 35 mobile sportsbook apps in the United States market last month by independent gaming research firm Eilers & Krejcik.

“We are excited to bring our industry leading gaming platform to Arizona, marking the second state in as many months where we have launched online sports betting,” said Richard Schwartz, Chief Executive Officer of RSI. “Moreover, with the sports calendar in full swing, and with the Arizona Cardinals near the top of the NFL, BetRivers could not be arriving in Arizona at a better time. We invite Arizonans to experience the huge volume of betting content and first-rate customer service we have to offer and see why BetRivers is the preferred sportsbook of more and more Americans.”

In August, RSI announced a multi-year market access partnership with the Arizona Rattlers, a long-tenured professional indoor football franchise in Phoenix. The Arizona Rattlers are one of the most accomplished professional sports teams in Arizona and are coming off a successful 2021 season where the team advanced to the Indoor Football League’s championship game, the United Bowl.

Mr. Schwartz said, “We are grateful for the trust and partnership of the Arizona Rattlers as well as the Arizona Department of Gaming, and look forward to delivering responsible, player-first entertainment to sports enthusiasts across the state.”
