New Jersey first paved the way for the first legalized US sportsbooks. Those same operators have now branched out into multiple states. Typically, online sports betting providers must have partnerships in place with land-based casinos. You must be aged 21 or over to join US sportsbooks and place bets. When you make bets, you’ll have to be physically located within the borders of the state where the sportsbook is licensed. In some states, you must be inside a casino or retail sportsbook when you place mobile bets. Sportsbooks use geolocation tools such as GeoComply to confirm your whereabouts.

Betting on Sports Online

US sportsbooks let you gamble on a multitude of sports and markets. Choose from major US sports like football, hockey and basketball, or find odds on the biggest soccer leagues overseas.

US Sports Betting Laws

Some US states had been eyeing up sports betting legislation since 2013 when New Jersey, Delaware and Nevada legalized online casinos.

However, it wasn’t until 2018 when the Supreme Court overturned PASPA (Professional and Amateur Sports Protection Act) 1992, a federal law banning betting on single games. With the law gone, individual states were free to legalize full betting on sports.

In 2021, there are many states that now offer legal and regulated sports betting. Some states issue licenses to online and mobile operators working in partnership with existing land-based casinos. Some states that have no brick ‘n mortar sportsbooks offer mobile-only betting options.  

In addition, many states allow betting on college sports. However, there are some restrictions, particularly on college sides playing in their home state.

Mobile Betting Apps

Many states allow mobile sportsbooks. In fact, some states only permit mobile apps rather than full online sports betting portals. Download a dedicated mobile sports betting app from the App Store (iOS) or Google Play Store (Android) to gamble on your smartphone or tablet. The sportsbook lobby and bet slip will be specially adapted to work on your smaller handset.
