Online gambling in the United States is legal — but only in specific states, and only with licensed operators. Unlike the UK, there is no federal framework that covers the whole country. Each state sets its own rules, and where you live determines what you can and cannot do legally online.
This guide tells you exactly which states have legal online gambling, what types are available, and how to find a legitimate, state-licensed operator wherever you are.
As of 2026: 8 states have legal online casinos (iGaming) · 30+ states have legal online sports betting · The US online gambling market generates $20B+ annually · All legal operators are licensed by state gaming commissions
The Legal Landscape: Why It's State-by-State
The key federal law is the Wire Act of 1961, originally intended to combat organized crime, and the Unlawful Internet Gambling Enforcement Act (UIGEA) of 2006, which restricts banks from processing certain gambling-related transactions but does not directly criminalize players.
The turning point came in May 2018, when the Supreme Court struck down the Professional and Amateur Sports Protection Act (PASPA) in Murphy v. NCAA. This opened the door for each state to legalize sports betting independently — and the market exploded.
Online casino gambling (iGaming) has a separate legal pathway. States must pass legislation specifically permitting online casino games, which is why far fewer states have it than have sports betting.
States with Legal Online Casino Gambling (iGaming)
As of 2026, eight states have fully legal online casino gambling where you can play slots, table games, poker and live dealer games with state-licensed operators:
New Jersey leads the US iGaming market with over $3.5B in annual revenue. Pennsylvania is second at ~$2.5B. See our full US states gambling infographic for the complete picture.
States with Legal Online Sports Betting Only
More than 30 states have legal online sports betting but do not permit online casino gambling. This includes major states like New York, Illinois, Colorado, Ohio, Virginia, Arizona, Tennessee and many others. See our interactive US gambling map for the full current list.
How to Verify a US Gambling Site is Legitimate
- Check your state's gaming commission website — each licensed state publishes a list of approved operators. Search "[your state] gaming commission licensed operators."
- Look for the state licence number in the footer — all legitimate US-licensed sites display their licence number and issuing jurisdiction.
- Geolocation is required — legal US gambling apps use GPS/IP geolocation to verify you are physically located in a legal state when you play. You will be blocked if you try to access from an unlegal state.
- Know your operator's parent company — major licensed operators include DraftKings, FanDuel, BetMGM, Caesars, and PointsBet. These companies have invested hundreds of millions in US licences and are credible.
Unlicensed offshore gambling sites operate outside US regulations. If they refuse to pay your winnings, you have no legal recourse. Some states actively prosecute operators (though rarely players). Stick to state-licensed operators — the licensed market has the same games and often better bonuses anyway.
How to Get Started at a Legal US Online Casino or Sportsbook
- Confirm your state has legal online gambling for the type you want (casino vs. sports)
- Download the app or visit the operator's website
- Register: you'll need your Social Security Number (SSN) for identity verification — this is standard and required by law
- Verify your age (21+ for casinos in most states; 18+ in some states for sports betting)
- Make your first deposit using a credit/debit card, ACH bank transfer, PayPal, or Play+ prepaid card
- Claim your welcome bonus
- Play only while physically located in a legal state — the app checks this each session
