Multi-State Gaming Agreements and Shared Liquidity
When people talk about states teaming up to share online gambling, they are almost always talking about one thing: the Multi-State Internet Gaming Agreement, or MSIGA. This page from BestSlotsUSA.com explains what that agreement is, which states have joined, and the point that trips up the most players. MSIGA pools online poker. It does not pool online slots. Those two products work in fundamentally different ways, and understanding why is the key to understanding this whole subject.
Below we cover the mechanics of shared liquidity, the current membership as of August 2026, the legal history that made interstate poker possible, and the one narrow place where slots do touch multi-state pooling: shared progressive jackpot networks. For the broader legal picture, see our legal hub, our state regulators guide, and the legislation tracker.
What the Multi-State Internet Gaming Agreement Is
The Multi-State Internet Gaming Agreement is an interstate compact. That is a formal, voluntary agreement between states that lets each state’s licensed online poker operators combine their player pools across state lines. A poker player logged in from New Jersey can sit at the same virtual table as a player logged in from Michigan or Pennsylvania, even though each person is regulated under the laws of a different state.
The plain-English idea at the center of MSIGA is shared liquidity. In gambling, liquidity means the number of real players available to bet against at any given moment. High liquidity means full tables, fast-filling tournaments, and a game that runs at all hours. Low liquidity means empty tables, tournaments that never reach a decent prize pool, and long waits for action.
Why Shared Liquidity Matters for Poker
Poker is a player-versus-player game. You do not play against the casino. You play against other people, and the house simply takes a small cut, called the rake, from each pot or tournament entry. That design makes poker completely dependent on having enough opponents. A poker room with only a few hundred active players struggles to offer variety. There are not enough people to fill high-stakes tables, run large tournaments, or keep games going at three in the morning.
Every state that legalized online poker on its own ran into the same wall. Even a state the size of New Jersey has a limited number of online poker players at any one moment. Smaller states like Delaware and West Virginia have far fewer. Standing alone, these markets were too thin to sustain a healthy poker economy.
Shared liquidity solves that. By combining player pools, MSIGA gives operators the critical mass poker needs. The benefits show up in three clear ways:
- Bigger player pools. More people online at once means more tables running, more stake levels available, and shorter waits to find a game.
- Better tournaments. Guaranteed prize pools that would be impossible in a single small state become realistic when four states feed the same tournament. Combined pools support marquee series with prize money in the millions.
- Healthier cash games. Deeper pools keep cash tables full across more stakes and more hours, which is what keeps recreational and serious players coming back.
In short, MSIGA does not change the rules of poker. It changes the size of the room. And for a game that lives or dies on the number of opponents at the table, size is close to everything.

Why Online Slots Do Not Use Shared Liquidity
This is the most important distinction on the page, and it is the one that gets muddled most often. MSIGA covers online poker only. It does not cover online slots, and slots do not need it.
The reason comes down to how the two games are built. Online slots powered by a random number generator, or RNG, are house-banked games. That means you play against the casino, not against other people. A random number generator decides the outcome of each spin the instant you press the button, and every spin is a completely independent event. The result does not depend on how many other people are playing, what they are doing, or whether anyone else is even online.
Because a slot outcome is self-contained, a slot game is fully functional with a single player. You do not need opponents to have a game. One person and one machine is enough. There is nothing to pool, because there is no shared pot of money that players compete over the way they do in poker. Each player wagers against the house and the house pays out according to fixed odds and a published return-to-player figure.
Contrast that with poker, where the money in play comes entirely from other players. Remove the opponents and poker stops working. Remove the opponents from a slot game and nothing changes at all. That single structural difference is why a poker compact exists and why no equivalent slot compact is needed for ordinary play. If you want the underlying mechanics of house-banked slot math, our real money slots guide walks through return-to-player and volatility, and our legal sites overview covers how licensed operators are approved state by state.
Poker. Player versus player. The house takes only the rake. Needs opponents to function.
Slots. House-banked RNG game. Every spin is independent. Works with one player.
Pooling players. Only poker benefits, because more people means fuller tables and bigger prizes.
Pooling money. The one slot exception is a linked progressive jackpot, covered next.
The One Way Slots Touch Multi-State Pooling: Progressive Jackpots
There is a single, narrow exception where slots brush up against the idea of pooling across locations, and it is worth explaining carefully because it is easy to overstate.
Ordinary slot play does not pool anything. But a progressive jackpot does. A progressive slot sets aside a small slice of every wager and adds it to a growing top prize. When many machines feed the same prize, the jackpot can climb into the millions. These are called wide-area progressives, because the prize pool is linked across a wide network of machines rather than sitting inside one game.
Here is the key point. Pooling a progressive jackpot is not the same as pooling players. In poker, the players themselves compete against one another in real time. In a linked progressive, the players never interact. They simply contribute to and win from a shared prize fund. The game each person plays is still a solo, house-banked slot. The link is only the jackpot money.
Where Linked Progressives Already Exist
In the land-based world, wide-area progressives have connected casinos for years. Some Atlantic City progressive slots have been interconnected with pools that reach machines on the Las Vegas Strip, and manufacturers run branded jackpot networks across many casino floors. In the online and omnichannel world, the industry has taken early steps too. IGT introduced what it described as the first omnichannel wide-area progressive link in the United States with a Wheel of Fortune slot in New Jersey, combining jackpot liquidity across the land-based, mobile, and online versions of the game.
But notice the boundary. That New Jersey link pools jackpot money within a single state, across different channels of play. It does not reach across state lines. As of August 2026, there is no regulated online progressive jackpot that pools contributions from players in different states into one interstate prize. Online progressive jackpots today are state-contained.
The Rule Change That Could Open the Door
That may be starting to shift, and Nevada is the state to watch. Nevada regulators have moved to rewrite a decades-old rule that governs linked progressive systems, aiming to cut the minimum required progressive contribution rate from 0.4 percent down to 0.1 percent. A lower minimum makes it more economical for casinos to link games across a wider network, which industry observers read as clearing a path toward multi-state jackpots. It is a technical change, but it is the kind of groundwork that has to come before any cross-border slot jackpot could operate. We return to the prospects for interstate slot jackpots in the future section below.
Bottom line. A linked progressive pools jackpot money, not players. The game you play is still a solo, house-banked slot, so no player-pooling compact is needed for slots to work.
MSIGA Membership as of August 2026
Six states are members of the Multi-State Internet Gaming Agreement as of August 2026: Nevada, Delaware, New Jersey, Michigan, West Virginia, and Pennsylvania. But membership tells only part of the story. Signing the agreement and actually going live with shared player pools are two different milestones, and the gap between them can last months or years. A state can put its name on the compact long before its operators flip the switch.
The table below separates those two facts. The first column asks whether the state has signed on to MSIGA. The second asks whether players in that state are actually competing in shared poker pools today. As of August 2026, all six member states have reached the live stage for at least one operator, but the depth of that live coverage varies a great deal.
| State | Signed MSIGA | Live on Shared Poker Liquidity | Notes |
|---|---|---|---|
| Nevada | Yes, founding member 2014 | Live | One of the two original signatories with Delaware. Offers online poker but not online slots. WSOP Online anchors the shared pool here. |
| Delaware | Yes, founding member 2014 | Live | The smallest member. Lost active poker service for about 18 months, then regained a live operator in June 2025 when BetRivers relaunched shared poker there. |
| New Jersey | Yes, joined 2017 | Live | The largest early market. Shared tables with Nevada and Delaware began in 2018. Home to multiple live networks today. |
| Michigan | Yes, joined April 2022 | Live | First non-original state to join. Shared liquidity rolled out across major networks beginning in 2023. |
| West Virginia | Yes, joined November 2023 | Live | Signed in late 2023 but had no shared poker until June 2025, when BetRivers became its first live interstate operator. A clear example of the gap between signing and launching. |
| Pennsylvania | Yes, joined April 2025 | Live | The sixth and largest member by online poker population. Governor Josh Shapiro signed the agreement April 23, 2025, and multi-state games reached players on April 28, 2025. Operator rollout is still expanding. |
Two entries deserve extra attention. West Virginia signed the compact in November 2023 but did not have a single live shared table until BetRivers launched there in June 2025, roughly a year and a half later. That delay had nothing to do with the compact itself and everything to do with whether any operator had built a licensed, connected poker room in the state. Pennsylvania, by contrast, moved quickly, going from the governor’s signature to live shared games in a matter of days, because operators were already in place and waiting. The lesson is that MSIGA membership is a legal permission slip. It is operators, not the compact, that turn shared liquidity on.

Which Networks Connect Which States
Shared liquidity does not connect every player in every member state to every other player automatically. Pools are built network by network. Two players can be sitting in the same state and still not share tables if they are on different poker platforms. What matters to a poker player is which network they are on and which states that specific network has combined. The table below summarizes the major connected networks as of August 2026.
| Network | States Combined | Notes |
|---|---|---|
| WSOP Online | Nevada, New Jersey, Michigan, Pennsylvania | Reaches the largest combined population of the connected networks, on the order of 35 million people. Runs the busiest tournament schedule with the biggest guaranteed prize pools. |
| BetMGM Poker | New Jersey, Michigan, Pennsylvania | Combined these three markets in late 2024. Shares its player pool with Borgata-branded online poker in Pennsylvania. |
| PokerStars | New Jersey, Michigan | Merged New Jersey and Michigan pools starting in 2023. Broader expansion to additional member states was still pending as of this review. |
| BetRivers Poker | Michigan, Pennsylvania, West Virginia, Delaware | The only network live in West Virginia and the operator that restored service to Delaware in 2025. Distinct footprint from the WSOP and BetMGM networks. |
Because footprints differ, the practical experience varies. A player in Nevada can only join the WSOP network, since that is the connected poker product available there. A player in West Virginia currently finds shared games through BetRivers. A player in New Jersey, Michigan, or Pennsylvania has the widest choice, with several connected networks competing for their play. Availability and operator lineups change as new integrations go live, so treat any snapshot as a moment in time rather than a permanent map.
History and Mechanics: How Interstate Poker Became Legal
To understand why an explicit interstate agreement was even necessary, you have to go back to a 1961 federal law and a pair of Justice Department opinions that flipped the legal landscape twice.
The Wire Act and the 2011 Opinion
The federal Wire Act of 1961 makes it a crime to use wire communication facilities to transmit certain bets or wagers across state lines. For decades the open question was whether that ban covered all gambling or only sports betting. In 2011, the Justice Department’s Office of Legal Counsel answered it. Responding to questions from New York and Illinois about selling lottery tickets online, the office issued an opinion concluding that the Wire Act applies only to sports gambling.
That 2011 opinion was the starting gun for legal online gaming in the United States. If the Wire Act did not reach non-sports online betting, then a state was free to authorize online poker, online casino games, and online lottery within its own borders. The catch was the phrase within its own borders. The permission was for intrastate gaming, meaning play that begins and ends inside a single state. Nevada, Delaware, and New Jersey each built online gambling markets on this foundation, but each market was walled off inside state lines.
Why Interstate Poker Needed Its Own Agreement
Intrastate authorization created a problem specific to poker. A state could license a poker site, but if that site could only serve players physically inside one state, its player pool was capped by that state’s population. For a game that depends on opponents, that cap was crippling, especially for small states.
The only way to combine pools legally was for states to affirmatively agree to let data cross their shared borders under mutually accepted rules. That is exactly what the Multi-State Internet Gaming Agreement is. Nevada and Delaware signed the first version in 2014, and New Jersey joined in 2017, with the three states launching shared tables in 2018. The compact set the terms under which each state’s regulator would recognize the others, so that a hand of poker spanning multiple states did not run afoul of any single state’s rules.
The 2018 Reversal and the Court Fight That Followed
In late 2018 the Justice Department reversed course. A new Office of Legal Counsel opinion concluded that the Wire Act was not limited to sports betting after all, and instead reached essentially all interstate gambling. Taken at face value, that reading threatened the legality of interstate poker compacts, interstate lottery games like Powerball, and any other bet that crossed a state line, even one fully permitted by state law.
The reversal was challenged in court. The New Hampshire Lottery Commission sued, and the case reached the United States Court of Appeals for the First Circuit. In January 2021, in New Hampshire Lottery Commission versus Rosen, the First Circuit held that the Wire Act’s prohibitions are limited to bets or wagers on sporting events or contests. In plain terms, the court sided with the 2011 reading and against the 2018 one. The Justice Department did not pursue the case to the Supreme Court, and the 2018 opinion was effectively left without force. That outcome is why interstate poker compacts have continued to operate and expand. It is worth noting that a court of appeals decision is binding law only within its own circuit, which is one reason the underlying uncertainty has never been fully resolved by Congress or the Supreme Court. For how these federal questions interact with state licensing, see our guide to state gaming regulators.
Geolocation Across Member States
Shared liquidity does not mean anyone anywhere can log in. Every hand still has to satisfy the law of the state each player is sitting in. Operators enforce this with geolocation technology that confirms a player is physically inside a member state before allowing real-money play. A player must be within the borders of a state that has both legalized online poker and joined MSIGA. Someone who drives across a state line into a non-member state loses access, and someone in a member state can play against opponents located in other member states because every seat at the table has been independently verified. Geolocation is the invisible machinery that keeps a multi-state game compliant. Our geolocation guide explains how the location checks work and why they occasionally flag players near borders.
The Future of Multi-State Gaming
MSIGA has grown slowly but steadily, from two states in 2014 to six in 2025. The obvious question is what comes next, both for poker and for the slot-side idea of shared jackpots.
Which States Could Join Next
The pool of realistic near-term candidates is small, because a state must first legalize online poker at all before it can think about sharing pools. The states most often mentioned as potential future members are Connecticut, Rhode Island, and Maine. Connecticut already has legal online gaming but a limited operator lineup, which makes shared poker plausible but not certain. Rhode Island and Maine are earlier in the process. Beyond that short list, any expansion depends on new states legalizing online poker in the first place, which the legislation tracker follows bill by bill.
Prospects for Shared Progressive Slot Jackpots Across States
The more forward-looking question for slot players is whether jackpots will ever pool across state lines the way poker pools do. The pieces are slowly moving into place. Wide-area progressives are already routine on land-based casino floors, omnichannel links now combine online and land-based jackpot money inside a single state, and Nevada’s move to lower the minimum progressive contribution rate is the kind of rule change that has to precede any interstate jackpot. It is reasonable to expect that shared progressive slot jackpots spanning multiple states will arrive before a general multi-state slot market does, because a jackpot link is technically and legally simpler than pooling players. As of August 2026, though, no regulated online slot jackpot pools contributions across state lines. It remains a prospect, not a product.
The Barriers Standing in the Way
Several real obstacles slow all of this down, whether the subject is poker or jackpots:
- Differing tax rates. States tax online gaming revenue at very different rates. When two states with mismatched tax structures share a pool, splitting and reporting revenue gets complicated, and neither state wants to feel shortchanged.
- Differing regulations. Each state writes its own technical standards, licensing requirements, and consumer rules. Harmonizing them enough to run a shared product takes negotiation and time.
- Small individual markets. Some candidate states are so small that operators question whether the cost of building and connecting a compliant product is worth it, which is part of why West Virginia waited so long for a live operator.
- Legal uncertainty. Because the Wire Act question was settled by a single appeals court rather than by Congress or the Supreme Court, a future administration could revive the 2018 interpretation, and that lingering risk makes some operators and states cautious.
Operator Consolidation
One more force shapes the future: consolidation. The online poker and casino business has concentrated around a handful of large operators and networks. That concentration cuts two ways. On one hand, big operators have the resources to build in new states and to connect pools quickly once a compact is signed, as Pennsylvania’s fast launch showed. On the other hand, fewer independent networks means fewer distinct player pools, and the health of shared liquidity ultimately depends on operators choosing to invest in each new market. The signing of a compact is necessary, but it is the business decisions of a shrinking set of operators that determine whether players ever see the benefit.

Frequently Asked Questions
What does MSIGA stand for and what does it do?
MSIGA stands for the Multi-State Internet Gaming Agreement. It is an interstate compact that lets member states combine, or pool, their licensed online poker player bases so that people in different states can play at the same tables. Its purpose is to give online poker enough players to sustain full tables and large tournaments.
Does MSIGA cover online slots?
No. MSIGA covers online poker only. Online slots are house-banked games where each spin is independent and you play against the casino, not other people, so slots do not need shared player pools to function. The only slot-related concept that involves pooling across locations is a linked progressive jackpot, and no regulated online slot jackpot pools money across state lines as of August 2026.
Which states are in MSIGA as of August 2026?
Six states: Nevada, Delaware, New Jersey, Michigan, West Virginia, and Pennsylvania. All six have at least one live operator offering shared poker, though the depth of coverage varies, and Nevada offers online poker but not online slots.
What is the difference between signing MSIGA and going live?
Signing the agreement is a legal step taken by a state. Going live is an operational step taken by licensed operators, who must build and connect a compliant poker room before players see shared tables. West Virginia signed in November 2023 but had no live shared poker until June 2025, which shows the two milestones can be far apart.
Can I play online poker against people in other states?
Yes, if you are physically located in a member state that has legalized online poker and you are playing on a network that has connected that state to others. Geolocation technology verifies your physical location before real-money play begins, and you can be seated with opponents located in other member states.
Why did the Wire Act matter so much?
The Wire Act of 1961 bans transmitting certain interstate bets by wire. A 2011 Justice Department opinion read it to cover only sports betting, which allowed states to launch online gaming within their borders. A 2018 opinion reversed that, threatening interstate poker, but a federal appeals court ruled in 2021 that the Wire Act is limited to sports wagering, and that ruling has allowed interstate poker compacts to continue.
Will slot jackpots ever be shared across states?
Possibly, and it may happen before a broader multi-state slot market does, because linking jackpot money is simpler than pooling players. Land-based wide-area progressives and single-state omnichannel links already exist, and Nevada has moved to loosen a rule that limited linked progressive systems. But as of August 2026 no regulated online slot jackpot spans state lines. It remains a future prospect.
Which network has the biggest multi-state poker pool?
WSOP Online currently reaches the largest combined population by connecting Nevada, New Jersey, Michigan, and Pennsylvania, on the order of 35 million people, and it runs the largest guaranteed tournaments. Network footprints change as new integrations launch, so the leader can shift over time.
