Rush Street Interactive (RSI) is an online gaming company that offers real-money online casino games and sports betting, primarily under the BetRivers and PlaySugarHouse brands in the U.S. and Canada, and the RushBet brand in Latin America. RSI operates in 16 U.S. states and four international markets: Ontario, Colombia, Mexico, and Peru. RSI describes itself as a "casino-first" company — online casino is its primary revenue driver, offering slots, table games, and poker, while sports betting is a smaller and more volatile contributor. RSI sells directly to consumers via its websites and mobile apps, with B2C accounting for more than 99% of revenue. RSI makes money through the house edge on casino games and a theoretical margin built into sports betting odds. Revenue scales with monthly active users and average revenue per user. RSI owns its gaming platform rather than licensing it, which allows it to build proprietary features like its iRush Rewards loyalty program, slot tournaments, and jackpot systems — content RSI argues drives higher player retention than competitors. RSI's business model benefits from operating leverage as fixed costs grow more slowly than revenue in maturing markets. RSI's growth strategy centers on entering new regulated markets quickly and deepening engagement in existing ones by developing proprietary casino content and expanding its multistate poker network. In Latin America, RSI views Mexico as its largest long-term opportunity, given its population and rapid early growth.
