Rush Street: US Online Casino Growth Cooling in 2026
RSI posts 39% revenue growth but warns the online casino engine is losing steam without new states.
Rush Street Interactive reported Q3 2026 revenue of $385.9 million — up 39% year over year — and adjusted EBITDA of $62.2 million, a 73% surge, yet its CEO flagged that U.S. online casino growth is decelerating (SBC Americas, October 2026).
Why It Matters
Online casino has been the primary engine of U.S. iGaming expansion, so any slowdown carries sector-wide implications. RSI's BetRivers brand competes in a handful of legalized states, and a cooling growth rate signals the existing addressable market may be approaching saturation. That pressure makes new-state legalization no longer a bonus but a necessity for continued double-digit revenue expansion. Investors watching RSI's full-year guidance of $1.56 billion to $1.6 billion should note the company is maintaining — not raising — that range, which itself signals tempered optimism.
Context
As of October 2026, legal online casino operates in fewer than ten U.S. states, leaving the majority of the population in jurisdictions where only sports betting or no digital gambling is permitted. RSI has consistently argued that broader legalization would unlock substantial incremental revenue, and its Q3 results — strong in absolute terms but narratively cautious — reinforce that argument. The company's 73% EBITDA growth suggests operational efficiency is improving even as top-line momentum softens.
What's Next
RSI signaled that 2027 represents a realistic window for new state-level online casino legislation, making upcoming state legislative sessions in early 2027 the critical near-term catalyst to monitor. Any movement in high-population states such as Texas or Illinois would materially change the growth calculus for RSI and the broader sector.
