Short answer: You can play real‑money online poker only on regulated, licensed sites in the U.S. states that have legalized it (availability varies by operator and state). The main reputable operators that currently run regulated, real‑money poker products in the U.S. include:

• WSOP.com (operated with 888) — strong presence in Nevada, New Jersey, Michigan, Pennsylvania and other regulated states via licensed operators. (PokerNews.com)
• PokerStars (licensed in New Jersey, Pennsylvania, Michigan and other states where it has launched) — large liquidity, tournaments and play‑money options. (PokerNews.com)
• BetMGM Poker — available in states where BetMGM holds a license (NJ, MI, PA in many cases) and often part of multi‑state pools. (MyPokerCoaching.com)
• PartyPoker (and BetRivers/brand families) — operates in some regulated states through partnerships/brands. Availability depends on each state’s licenses. (DeucesCracked.com)

Important legal context for U.S. players

• Online poker is regulated state‑by‑state. As of 2025, only a subset of states permit regulated, real‑money online poker (commonly listed: Nevada, New Jersey, Delaware, Pennsylvania, Michigan, West Virginia — with Connecticut and Rhode Island also involved in various ways). Many sources show that interstate compacts (MSIGA) let some states share player pools to improve liquidity. Check your specific state before trying to register or deposit. (PokerNews.com)

Safety and practical advice

• Use only licensed, regulated sites in your state. Regulated operators offer player protections (identity checks, age limits, dispute resolution, verified payouts). Offshore/unregulated sites may be illegal to use from the U.S. and expose you to fraud, payment problems, or account seizure. (PokerNews.com)
• Confirm whether the operator is licensed for your state before creating an account—some brands operate in some states but not others. (MyPokerCoaching.com)
• Read the site’s terms, withdrawal rules and bonus playthrough requirements. Use secure payment methods and enable any available account verification (2FA).
• Practice responsible gambling: set deposit/time limits, and use self‑exclusion tools if you need them. Regulators and operators provide resources. (theguardian.com)
