Rush Street Interactive's Multi-State Poker Expansion: A Play for Dominance in the U.S. Online Gaming Landscape

The U.S. online poker sector remains fragmented, with operators often constrained by state-by-state regulatory silos. Into this landscape strides Rush Street Interactive (RSI), whose June 2025 expansion of its BetRivers Poker platform into Delaware, Michigan, and West Virginia marks a bold move to consolidate fragmented markets into a unified, high-margin ecosystem. By merging player pools across four states—Pennsylvania, Delaware, Michigan, and West Virginia—RSI is not only solving liquidity challenges but also setting the stage for a revenue diversification play that could redefine the industry.

The Power of Cross-State Liquidity: Solving Poker's "Empty Tables" Problem

Online poker's profitability hinges on consistent player engagement, which requires critical mass. Until now, operators faced a dilemma: states like Delaware and West Virginia had small player bases, leading to thin liquidity and unappealing prize pools. RSI's expansion unites these markets into a single network, creating deeper cash-game fields and larger tournament pools. This consolidation directly addresses the sector's liquidity bottleneck, a critical differentiator in an industry where empty tables drive user attrition.

The financial upside is clear: a unified network reduces operational complexity while increasing per-player revenue through higher-stakes tournaments and consistent action. Margins are further bolstered by RSI's proprietory platform control, as it operates as the sole provider in Delaware and West Virginia—a position it will likely replicate in New Jersey when its rollout there begins later in 2025.

Proprietary Tech, Celebrity Endorsements, and the "Network Effect"

RSI's BetRivers platform isn't just a liquidity aggregator—it's a technology-driven experience. Features like real-time dynamic avatars, Cub3d tournaments (with 1,500x buy-in prizes), and community-designed interfaces create sticky engagement. But RSI's ace card is its strategic partnerships:

• Phil Galfond, founder of Run It Once Poker (acquired by RSI in 2022), oversees platform development, emphasizing fairness and player-centric design.
• Phil Hellmuth, the 17-time WSOP champion, amplifies reach through branded content and live events, leveraging his 2 million social media followers to drive adoption.

These partnerships inject credibility and excitement into the brand, critical in a sector where trust and community are paramount.

Scaling the Cross-Jurisdictional Model: New Jersey and Beyond

The imminent New Jersey rollout is a game-changer. As the nation's second-largest online poker market (after Pennsylvania), its addition would create a five-state network—the largest in the U.S. outside the WSOP—and vault RSI into pole position. The scalability here is undeniable: each new state adds incremental revenue with minimal marginal cost, as the platform's infrastructure already supports multi-state integration.

Moreover, RSI's omnichannel strategy ties online play to its Rivers Casinos properties, creating a hybrid ecosystem where online users can transition to in-person tournaments and vice versa. This integration deepens customer lifetime value and reduces churn.

The Investment Case: A High-Margin Play with Underappreciated Upside

RSI is executing a textbook consolidation play in a nascent but high-margin sector. By unifying fragmented markets, leveraging proprietary tech, and exploiting celebrity-driven marketing, it's creating barriers to entry that few competitors can match. The New Jersey rollout alone could add ~15% to its addressable market, while cross-state liquidity boosts margins by reducing operational inefficiencies.

RSI's forward-looking statements hint at further expansions, with 15 U.S. states already in its portfolio. Yet, its stock remains undervalued relative to its growth trajectory. Investors should note that regulated online poker adoption is accelerating—U.S. online poker revenue grew 22% YoY in 2024—and RSI is positioned to capture the lion's share of this growth.

Conclusion: Capitalize on RSI's Dominance Before the Crowd Catches On

Rush Street Interactive is no longer just a poker operator—it's a market consolidator building a scalable, high-margin empire. Its multi-state network, celebrity-driven growth, and strategic use of liquidity-driven economics make it a rare pure-play opportunity in a sector primed for expansion. For investors seeking exposure to regulated online gaming's next chapter, RSI's underappreciated growth trajectory and imminent catalysts make it a buy now at current valuations.
