Rush Street Interactive (RSI) has merged its online poker player pools in four US states with the expansion of its BetRivers Poker platform.

The poker offering for RSI’s flagship operator brand has gone live in Delaware, Michigan and West Virginia after launching in Pennsylvania in November 2024.
The expansion will create larger player pools by allowing players to take part in games across state lines, leading to bigger tournament prize pools, RSI said.
RSI also plans to launch BetRivers Poker in New Jersey later this year.
“The launch of a unified cross-state player pool significantly enhances the BetRivers Poker experience,” said Richard Schwartz, CEO of RSI. “By expanding the network, we’ll bring more players to our tables, offer a wider variety of games and raise the stakes with larger tournament prize pools.
“We're thrilled to strengthen our poker footprint and deliver best-in-class competition and community-driven play across multiple states.”
BetRivers Poker offers cash games, Sit & Go tournaments and Multi-Table Tournaments, while on-game avatars allow players to react to gameplay.
In April, Pennsylvania joined New Jersey, Delaware, West Virginia and Michigan in the Multi-State Internet Gaming Agreement (MSIGA) for poker.
