Michigan – Online casino revenues across key U.S. states posted striking gains this week, with Rush Street Interactive’s BetRivers hitting a milestone and state regulators reporting record or near-record September results that underscore a booming North American iGaming market.
BetRivers Breaks $20 Million in Michigan
A milestone month for Rush Street
BetRivers logged $20 million in online casino revenue for September 2025, becoming only the fourth operator in Michigan history to clear that monthly mark alongside FanDuel, BetMGM and DraftKings. The milestone—confirmed in industry reporting on October 20, 2025—capped a stretch of consecutive monthly records for the Rush Street Interactive skin and reflected a 62.6% year-on-year jump for the operator in the Wolverine State. CasinoReports’ breakdown of Michigan results details the figures and operator rankings.
Statewide Gains and Regional Momentum
Pennsylvania posts the second-highest iGaming month ever
The Pennsylvania Gaming Control Board reported $233.4 million in adjusted gross online casino revenue for September 2025, the second-largest monthly haul in state history and a 32.1% increase from a year earlier. Combined gaming revenue across land-based casinos, sports wagering, video gaming terminals and iGaming reached $535.8 million in September, signaling broad-based strength across verticals.
Across multiple regulated markets, September’s figures point to sustained consumer demand and diversification of player preferences – from slot titles and live-dealer offerings to branded operator collaborations that roll out exclusively in regulated U.S. states.
Industry Drivers and Operator Strategies
Product, partnerships and market access
Operators are citing a mix of new content releases, targeted promotions and expanded market access as drivers of the uptick. Vendors and studios continue to roll out U.S.-specific titles and exclusives designed to resonate with local audiences, while operators push loyalty and VIP programs that lift player retention and average revenue per user.
At the same time, competition among skins under single-operator umbrellas remains fierce: Rush Street’s BetRivers pushed growth with aggressive promotion and an expanding game library, while legacy sportsbook-turned-casino brands continue to leverage cross-sell opportunities between sports wagering and iCasino products.
Regulatory and Tax Risks Loom Abroad
Policy headwinds could reshape economics
While U.S. states report revenue highs, industry participants and analysts warn that policy shifts elsewhere could temper global operator strategies. In the U.K., industry groups reacted strongly to rumors and proposals around tax increases on betting and online slots in budget planning, warning of potential retail closures and an altered cost structure for operators – a reminder that regulatory risk remains a major variable in global expansion plans.
What to watch next
Analysts will be tracking October report cycles and operator earnings calls for clarity on whether September’s surge represents a sustained trend or a peak driven by specific product launches and marketing pushes. For now, the combination of strong state-level results and landmark operator milestones like BetRivers’ $20 million month paints a bullish near-term picture for regulated U.S. iGaming.
