Shared liquidity
MSIGA and shared poker liquidity: which states actually pool players
The short answer
MSIGA is the compact that lets licensed US poker sites pool players across state lines. Six states have joined — DE and NV (2014), NJ (2017), MI (2022), WV (2023) and PA (April 2025) — but membership only permits sharing; an operator still has to connect its pools. West Virginia's first shared-pool games launched via BetRivers in June 2025, and Pennsylvania's member sites are progressively linking in.

Online poker has a scale problem: ring-fenced state pools are too small to sustain healthy game selection, which is why the industry built the Multi-State Internet Gaming Agreement — a compact letting operators seat players from different states at the same tables. But 'MSIGA member' on a map and 'shared liquidity live' on a client are different claims, and the gap between them trips up a lot of coverage.
Illustrative example
| State | Joined MSIGA | Shared liquidity live? |
|---|---|---|
| Delaware | 2014 (founding) | Yes — original NV/DE network |
| Nevada | 2014 (founding) | Yes — original NV/DE network |
| New Jersey | 2017 | Yes — joined the shared network |
| Michigan | 2022 | Yes — connected after accession |
| West Virginia | 2023 | First pooled games June 10, 2025 via BetRivers |
| Pennsylvania | April 2025 | Acceded to the compact; operators progressively connecting |
Why the two steps differ
Accession is a legal act: the state joins the compact and its regulator blesses interstate pooling in principle. Going live is an engineering and compliance act: the operator has to certify its platform for cross-border pooling — KYC across jurisdictions, wallet segregation, geolocation on every login — and the regulators of both ends have to accept it. West Virginia illustrates the lag: it joined in 2023, but its first connected games didn't run until June 2025, when an operator actually turned the feature on.
What pooling changes
- Bigger effective pools: cash-game liquidity and tournament guarantees scale with the combined player base — the main reason the compact exists.
- Shared networks, separate skins: an operator runs one pooled back end but may still market under state-specific brands; the player sees a local site.
- Not every member state's players are pooled by every operator: liquidity is per-operator, so two MSIGA states can share on one platform while staying ring-fenced on another.
- Online casino is unaffected: MSIGA covers peer-to-peer poker (and similar P2P games); house-banked iGaming stays inside state lines.
