Online Betting in the United States
With the exception of Nevada, Oregon, Delaware, and Montana online sportsbook sites in
the United States are illegal. In a September 2017 poll conducted by the Washington
Post, 55% of the majority of adults said they would approve the legalization of online sports
betting in the United States.
As with most forms of online gambling sites in the United States, sports betting has been heavily restricted since the passing of the Unlawful Internet Gambling and Enforcement Act of 2006. Luckily, however, the federal government changed the law in 2012, allowing individual states to launch their own online gambling operations, so long as they were limited to play within state borders.
As of December 2013, three states have launched their online operations: Nevada, New Jersey and Delaware all came live throughout the latter half of the year. Nevada ran the first of the legal online sportsbooks in the United States aim at the casino punters in Las Vegas.

Sports Betting in the United States
Casual sports betting has always been popular in the US, from office pools to friendly wagers among friends. Organized sports betting, however, is limited by law. In the United States, the Professional and Amateur Sports Protection Act of 1992 makes it illegal to operate a "betting, gambling or wagering scheme", with the exception of Nevada, Delaware, Oregon and Montana.
The only state to challenge this “federally legislated discrimination” has been New Jersey, when it allowed sports bets to be placed at its horse racing tracks and in casinos, invoking outrage from all major sports associations. The matter is expected to ultimately play out in the US Supreme Court in 2013 or 2014, setting a precedent for other states either way.
