There was a federal ban on sports Gambling in the United States from 1992 to 2018 Beneath the Skilled and Amateur Sports Protection Act (PASPA).

The 1992 law granted resistance to four countries that had previously permitted sports gambling inside their boundaries. Those countries are Nevada, Delaware, Oregon, and Montana.
The condition of New Jersey contested the legality of PASPA. The Supreme Court heard oral arguments in late 2017. On May 14, SCOTUS issued a decision reversing the ban, hitting down PASPA in full by a vote of 6-3. Due to the conclusion, the following states now offer legal sports gambling:
Delaware — Launched June 5, 2018
Sports Betting in New Jersey — Launched June 14, 2018
Mississippi — Launched Aug. 1, 2018
West Virginia — Launched Aug. 30, 2018
Sports Betting at Pennsylvania — Launched Nov. 16, 2018
Rhode Island — Launched Nov. 26, 2018
Arkansas — Launched July 1, 2019
Countries who have passed sports betting legislation, but haven’t launched it yet:
Tennessee — April 30, 2019
Montana — May 3, 2019
Indiana — May 8, 2019 (get a Complete FAQ here)
Iowa — May 13, 2019
Illinois — June 2, 2019
Delaware was really the very first into the enlarged marketplace. The state used the existing sports betting law on its books, based single-game wagering regulations, and began taking stakes on June 5, 2018.
A property in New Mexico also started booking legal wagers on Oct. 16. Santa Ana Star Casino & Hotel signed a deal with USBookmaking in early October to establish a sportsbook.
What makes New Mexico an interesting case is that Santa Ana is a tribal property. Mississippi was the first state to start tribal sports betting, but it had been done in tandem with a state law. In Santa Ana’s case, sports gambling is still illegal elsewhere in the state, but the tribe can accept bets on its own land.
The Pueblo of Santa Ana Gambling Regulatory Commission regulates the casino’s wagers.
