As of 2026, legal sports betting is available in 39 states plus Washington D.C. and Puerto Rico, following the Supreme Court's May 2018 ruling that struck down PASPA and returned sports-wagering authority to each state. Eleven states still have no legal framework in place — Hawaii and Idaho among them, with Hawaii potentially regulating by 2026 according to industry observers.
Which States Have Legal Sports Betting?
The majority of states that moved quickly after PASPA launched both retail and mobile sportsbooks, meaning you can place a bet from your phone rather than driving to a casino. A handful allow only retail wagering. The RG.org regulatory tracker maintains current launch dates, tax rates, and the specific regulator for each state — the most reliable single reference we've found for checking a state's live status.
What Is the Minimum Age to Bet in My State?
Most legal states set the floor at 21, matching existing casino gambling age requirements. A smaller group technically permits 18+ wagering, but casino-based sportsbook floors may still enforce 21 because of alcohol service rules. For the full breakdown, see our guide to sports betting minimum age requirements by state.
Does My Home State or My Physical Location Control Eligibility?
Physical location at the moment you place a bet is what matters — not your home address, billing address, or where your bank account is registered. Every licensed sportsbook app uses geolocation software to verify you're inside state lines before accepting a wager. Cross into a state where betting is illegal and the app simply won't process the bet. Our sportsbook geolocation explainer walks through exactly how that technology works and what to do if it misreads your location.
Why Not Just Use an Offshore Site?
Offshore and unlicensed sportsbooks operate outside every consumer-protection framework that licensed books must follow. There is no regulator to call if a payout is withheld, no deposit insurance, and no recourse if the site goes dark. The risks are real and documented — read our full breakdown of why illegal offshore books leave bettors unprotected before considering that route.
How Do State Laws Affect the Picks You Use?
The picks themselves — expert predictions on NFL spreads, NBA totals, NHL moneylines — are informational content available anywhere. What changes by state is which licensed sportsbook you can legally use to act on those picks. Once you've confirmed your state is legal and you're physically inside it, you can browse free expert sport betting picks for any sport and compare lines across the licensed books available in your market.
State laws can also shift quickly; Kentucky, for example, moved from an 18-minimum to a 21-minimum via a legislative veto override. Always verify current law through your state's gaming regulator or the RG.org tracker before wagering. Must be 21+ (18+ in some states). Gambling problem? Call 1-800-GAMBLER.
