the current landscape for legal betting sites
In 2018, the game changed dramatically for sports bettors in the US. That May, the Supreme Court placed sports betting legalization and regulation into the hands of the individual states. The dominoes started to fall rapidly over the summer, and haven’t stopped since.
States including Delaware, New Jersey, and Pennsylvania opened the floodgates, and additional markets followed in rapid succession over the following years. Today, sports betting of at least some kind is allowed in 38 states plus Washington DC.
When did sports betting become legal?
States have been legalizing sports betting one-by-one since 2018 when the U.S. Supreme Court struck down the bill (Professional and Amateur Sports Protection Act) that previously banned sports wagering.
Each individual state has its own regulators who decide which bets are legal. With each state having its own set of rules, our state-by-state betting guide (at the bottom of this page) can be useful.
What's next for legal online sports betting
Legal online sports betting is now entrenched in much of the US, but there’s still room to grow. States that appear to be inching closer toward legalization include Missouri, while massive markets such as California and Texas have yet to enter the fray.
A clear hierarchy has developed among sportsbook operators, with Fanduel establishing itself as an industry leader. Other top betting sites like Caesars, BetMGM, and bet365 have staked their claim to solid shares of the market, making it that much tougher for new entrants.
