US Sports Betting Laws: State-by-State Legal Guide 2026
The American sports betting landscape has undergone a dramatic transformation since May 2018, when the Supreme Court struck down the Professional and Amateur Sports Protection Act (PASPA) in Murphy v. NCAA. What was once a $150 billion underground industry is now a regulated, tax-generating market operating legally in the majority of U.S. states. This guide covers the legal framework, the current state of affairs, and what bettors need to know to stay on the right side of the law.
The Fall of PASPA
Before 2018, PASPA effectively banned sports betting nationwide with a narrow exemption for Nevada. New Jersey challenged the law after years of effort, arguing that it violated the Tenth Amendment by commandeering state legislatures. The Supreme Court agreed in a 7-2 decision, ruling that PASPA was unconstitutional because the federal government cannot prohibit states from authorizing sports wagering.
The ruling did not legalize sports betting nationally. Instead, it gave each state the authority to legalize and regulate sports wagering on its own terms. This has created a patchwork of regulations that vary significantly from state to state.
Current Legal Landscape in 2026
As of early 2026, over 35 states plus the District of Columbia have legalized some form of sports betting. The breakdown includes:
**Online and retail legal (25+ states):** States like New Jersey, Pennsylvania, Colorado, Illinois, Michigan, Arizona, New York, Ohio, Massachusetts, and Maryland allow both online mobile betting and in-person wagering at licensed locations. These states offer the most convenient betting experience.
**Retail only (5-7 states):** Some states like Montana, New Mexico, and Wisconsin allow sports betting only at physical locations such as casinos, racetracks, or tribal gaming facilities. You cannot bet from your phone or computer in these states.
**Legal but not yet launched:** A few states have passed legislation but have not yet launched operations due to regulatory delays or ongoing negotiations over licensing frameworks.
**Not yet legal:** States like California, Texas, Georgia, and a handful of others have not yet passed sports betting legislation, though bills are introduced regularly. See [state guide](/states) for legality details and the latest updates for your specific state.
Key Regulations Bettors Must Know
**Age requirement:** You must be 21 or older to bet on sports in most states. A few states set the age at 18, but the standard across the industry is 21.
**Geolocation:** Every legal sportsbook uses geolocation technology to verify you are physically located within a legal state when placing bets. You cannot bet from a state where sports wagering is illegal, even if your account is registered in a legal state. VPNs that attempt to spoof your location violate the terms of service and can result in account closure and forfeiture of funds.
**Identity verification:** KYC (Know Your Customer) requirements mean you must provide your full legal name, date of birth, Social Security number, and address. This is a regulatory requirement, not optional.
**Bet restrictions:** Most states prohibit betting on in-state college player props and some restrict wagering on amateur or high school events entirely. A few states have unique restrictions on certain bet types.

Frequently Asked Questions
Can I bet on sports while traveling to another state?
Yes, as long as the state you are visiting has legalized sports betting and you are using a licensed sportsbook that operates there. Your home state does not matter; what matters is your physical location when placing the bet. Some sportsbooks like DraftKings and FanDuel operate in many states, so your existing account may work automatically when you cross state lines.
What happens if I bet on an offshore site from a state without legal betting?
Offshore sportsbooks are not licensed by any U.S. regulatory body. Using them carries risks including no consumer protections, potential difficulty withdrawing winnings, and possible legal consequences depending on your state's laws. While enforcement against individual bettors is rare, using unlicensed sites means you have no recourse if something goes wrong.
Will sports betting eventually be legal in all 50 states?
It is difficult to predict, but the trend is clearly moving toward broader legalization. States see the tax revenue generated by neighboring states with legal betting and face political pressure to capture that economic activity. However, some states have strong anti-gambling lobbies or constitutional barriers that may delay or prevent legalization indefinitely.
