Official Betting in the US

Official betting is a term used to describe wagers that are legal and regulated in a particular state. These include bets on professional and collegiate sports.

The sports betting industry is currently dominated by three major sports in the United States: NFL, NBA and MLB. Each of these leagues has a large and dedicated fan base, and each one produces a wide range of events.

While these sports offer the most action, many other popular sporting events and leagues are also worth placing a bet on. These can include golf, soccer, tennis, horse racing and more.

What’s more, many of these sports also feature regular player props and odds boosts that can be a good source of income for sports bettors.

How to bet legally

The first step to becoming a legal sports bettor in the US is to determine which states allow online and mobile gambling. There are nine states that do, and they’re all positioned to take advantage of the Supreme Court ruling in 2018.


The state launched online sports betting in May 2021 and has partnered with multiple operators to provide residents with access to a variety of games. However, all betting on in-state collegiate teams is prohibited, including player prop bets.


Colorado became the 19th state to legalize sports betting in May 2020, and residents can now place bets online at multiple sportsbooks. There are a few restrictions on in-state college games, such as betting on game outcomes only, and the ability to place a wager on a player prop bet is limited.
