Online NBA parlay betting is legal and available in 32 states as of mid-2024, with Missouri becoming the 39th state to legalize sports betting on December 1, 2024. Two states — Utah and Hawaii — have no legal sports betting of any kind, full stop.
Which States Have Legal Online NBA Parlay Betting?
The states confirmed with legal online sports betting include Arizona, Arkansas, Colorado, Connecticut, Delaware, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia, among others. Nevada was the first state to legalize sports betting, going back to 1949, and now offers online and mobile wagering as well.
A handful of states have legalized sports betting but restrict it to in-person kiosks only — Mississippi and Montana, for example. That means you can't fire up a DraftKings app from your couch in those states and build a five-leg NBA parlay. Worth knowing before you travel.
New Jersey's legal battle against the federal ban on sports betting led to the landmark 2018 Supreme Court ruling in Murphy v. NCAA, which opened the door for all states to set their own rules. Pennsylvania launched online sportsbooks that same year. The map has expanded steadily ever since.
Where Is NBA Parlay Betting Still Off the Table?
Utah and Hawaii remain the only two states with zero legal gambling of any kind — no sports betting, no casinos, nothing. If you're in either state, no licensed sportsbook will process your bet. Geolocation blocks it automatically.
Some states allow in-person wagering only, so check your state's current rules before assuming mobile access. The National Council on Problem Gambling maintains state-by-state responsible gambling resources that can also point you toward your local regulator.
Does Legality Affect Which Sportsbooks You Can Use for NBA Parlays?
Yes, directly. DraftKings, FanDuel, bet365, BetMGM, Fanatics, and Caesars are all licensed across multiple legal states, but not all of them are live everywhere. Before building your NBA parlay picks for tonight's slate, confirm the operator is licensed in your state by checking the footer of the app for a state gaming control board license number.
Line shopping matters too. Odds vary from book to book, and the DraftKings vs FanDuel vs bet365 parlay odds comparison breaks down which platform tends to offer the sharper lines on NBA markets.
What About the Parlay Calculation Once You Know You're in a Legal State?
Once you've confirmed legal access, payout math is the next thing to nail down. Two legs at -110 each pay roughly +264 on a $100 wager — that's $264 profit, $364 total return. Add legs and the multiplier climbs fast, but so does the probability of a single leg sinking the whole ticket. Use the NBA parlay payout calculator to run the numbers before you commit.
Taxes apply wherever you are. Winnings above $600 or 300× your wager trigger a W-2G from the operator, and all gambling income is reportable on Form 1040, Schedule 1. More detail is in the IRS rules for NBA parlay wins.
