Shared liquidity: what MSIGA merges, and what stays in your state

What the compact is, in order

The agreement began as a two-state arrangement between Nevada and Delaware in 2014, with New Jersey joining in 2017 — the first time an interstate online poker pool reached a market of real size. Michigan followed, and West Virginia signed as well. Pennsylvania became the sixth member in April 2025 when the governor gave final approval, and the Pennsylvania Gaming Control Board confirmed that shared-liquidity online poker would go live on 28 April, with BetMGM Poker and Borgata Poker named as the first rooms to open cross-state games. In its announcement the board put the size of the market it was connecting at roughly 150,000 online poker players.

Operator approvals continue separately after a state signs. In April 2026 the Michigan Gaming Control Board approved FanDuel to participate in the agreement, following the move of PokerStars onto the FanDuel platform — a reminder that the compact governs states, while the lobby is governed by whose licence is current.

Why two players in compact states still cannot meet

Picture two rooms. One holds licences in New Jersey, Michigan and Pennsylvania on a single network; its players meet at the same tables. The other holds a licence in one state only, and its $0.25/$0.50 game is as thin as it was before the signing. Both are legal, both are in compact states, and only one of them benefited.

This is why "state X joined" is an incomplete answer to "will my games be better". The questions that decide it are:

• Does my room operate in more than one member state?
• Are those sites on the same network, not merely under the same brand family?
• Has each state’s regulator approved that room for multi-state play?

Three pages here carry the answer, kept current rather than from memory:

• Room list — which brands run in which state.
• Multi-state poker — who is inside the compact.
• State detail: New Jersey, Pennsylvania, Michigan.

What the merge actually changes

Shared liquidity changes two things that players feel and one they do not.

Table count at off-peak hours. A pool three times the size does not simply triple the tables; it makes the marginal game viable — the second $1/$2 table, the four-handed PLO game, the mid-afternoon tournament that used to cancel.

Guarantee sizes. Tournaments are where pooling shows up fastest, because a bigger field lets a room advertise a larger guaranteed prize pool without carrying as much risk of paying the gap itself. If you have ever wondered who funds the difference when a guarantee is not met, that is overlay.

What it does not change: your account. The wallet, the verification, the deposit methods and the responsible-gaming tools stay state-side. You remain a player licensed under your own state’s regulator, playing from inside its borders, with its geolocation checks on every login — the compact does not travel with you when you drive somewhere else. That mechanism is its own subject: why a legal account fails at the state line.

The parts that never pool

Three more things stay firmly inside the state line, and conflating them with poker liquidity is the most common misreading of the compact:

• Casino games. Slots and table games are not within the agreement. A shared poker table and a state-only casino lobby coexist on the same site by design — see the casino hub for what that catalogue looks like per state.
• Sports betting. Separate licence, separate rules, no pooling.
• Rake and promotions. Rake schedules, loyalty systems and bad-beat promotions are set per room and per network, which is why two players at the same shared table can be paying different effective rates if they entered through different state sites. The arithmetic behind that is in rake caps at micro stakes.

What to watch next

The pattern since 2014 has been that each new member is slower than the headline suggests and better than the sceptics expect: the signing comes first, the regulator’s operator approvals come next, and the lobby changes when a network with licences on both sides decides it is worth merging. Bills elsewhere are drafted with membership written in, which tells you legislatures now treat joining as the default rather than the experiment.
