Online Poker’s Shared-Liquidity Push Gains Steam as State iGaming Revenue Climbs
As state revenue reports roll in for late 2026, the six-state Multi-State Internet Gaming Agreement (MSIGA) is drawing fresh attention from regulators and players. West Virginia’s September results and recent months from New Jersey and Michigan show year-over-year growth, even if the pace differs. That financial momentum is one reason conversations about adding more states to shared online poker player pools have not gone away.
West Virginia’s strong but slowing September
Online casinos in West Virginia generated $38.8 million in revenue in September 2026, up 14% on the same month a year earlier. It was one of the strongest months on record, but it was also the weakest annual growth observed in the market to date after years of 30% or more each month. Growth in July and August had already slowed to roughly 20%, and the September dip suggests the market may finally be reaching a saturation point.
Bet365’s first full month in West Virginia produced $631k, or 1.6% of the market. Mountaineer casinos, which include BetRivers and the state’s only online poker room, grew 40% year-over-year to $8.6 million and were the top performer. Charles Town, primarily DraftKings, was up 12% and leads the market overall.
Michigan’s growth and the maturity debate
Michigan online casinos launched on January 22, 2021, and online poker followed a week later. Licenses are held by 12 tribes and the three commercial Detroit locations, for a total of 15. Gross revenue under $4 million is taxed at 20%, and gross revenue above $12 million is taxed at 28%; Detroit casinos pay an additional 1.25% internet tax to the city.
The state’s annual online casino revenue grew from $1.11 billion in 2021 to $3.09 billion in 2025. The 2026 pace is $3.61 billion, a 17% rise. June 2026 growth was 25.2% year over year, compared with 14.2% for Pennsylvania. The Michigan Gaming Control Board reports, as summarised by PlayMichigan, note: “While we won’t speculate on when the market will ultimately mature, current trends suggest we have not yet reached that point.”
MSIGA’s six-state footprint
The Multi-State Internet Gaming Agreement now has six members: Delaware, Michigan, Nevada, New Jersey, Pennsylvania and West Virginia. It allows poker sites active in at least two member states to seat players from different states at the same tables, creating larger tournaments and busier cash games. Delaware and Nevada signed the agreement on February 25, 2014, and New Jersey joined in October 2017.
Connecticut is listed as a potential future member. If you want a free dice game between poker sessions, try Farkle online free.
New Jersey’s record-setting stretch
New Jersey online casino operators reported $258.9 million in January 2026, up 16.8% year over year and the third-highest month in state history. June came in at $271.0 million, up 17.5% from a year earlier, after a May record of $276.3 million. Through the first six months of 2026, New Jersey iGaming revenue was $1.59 billion, up 15% from $1.39 billion in the same period of 2025. August revenue was $259.3 million, up 4.4% year over year, with year-to-date revenue of $2.13 billion.
The June operator data also show the more modest scale of online poker brands inside a much larger casino market. WSOP reported $1,305,431 and PartyPoker $1,353,933, while PokerStars did not report revenue that month after reporting $1,148,389 a year earlier.

Legislative movement to watch
As of May 2026, online sports betting was authorised in 39 states plus Washington DC, while online iGaming was authorised in eight states. Several states moved on some form of online gambling authority in the first half of 2026, including Maine and Alabama with sports betting bills, North Carolina with an expanded sports-betting framework and online casino discussion, and Maryland, where an iGaming bill moved through committee for the second year running. Three states had iGaming bills mid-flight that may close in 2026: New York, Illinois and Indiana.
The state-by-state legal status shows Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, Rhode Island and West Virginia with authorised iGaming, while New Hampshire is limited. Readers who track these licensing changes professionally may value recurring link building support.
What to watch next
Shared liquidity can quickly improve tournament guarantees and cash-game traffic, and Pennsylvania’s quick use of MSIGA shows operators are ready to connect pools once a state joins. The larger question is which state acts next. New York, Illinois and Indiana all have iGaming bills in play, and Connecticut remains a potential MSIGA candidate.
For players, the practical effect is still state-dependent. Single-state markets will continue to have smaller fields until more states enter the compact. Watch the pending bills and any regulator statements on compacts; those signals will determine whether the next shared-liquidity expansion becomes a 2026 story or a 2027 one.
