In the United States, it was previously illegal under the Professional and Amateur Sports Protection Act of 1992 for states to authorize legal sports betting, hence making it effectively illegal. The states of Delaware, Montana, Nevada, and Oregon—which had pre-existing sports lotteries and sports betting frameworks, were grandfathered and exempted from the effects of the Act.[6]

While the National Basketball Association (NBA) was once active in preventing sports betting law relaxation, current NBA Commissioner Adam Silver became the first major sports leader to break from previous administrative opposition to gambling. In 2014 he stated in a New York Times op-ed, "I believe that sports betting should be brought out of the underground and into the sunlight where it can be appropriately monitored and regulated."[44] In 2017, with support for legalization growing, he confirmed his belief that "legalized sports betting is inevitable".[45]


Unlike Las Vegas, where you can physically visit a sportsbook at a casino resort, online gambling sites and sportsbooks are essentially virtual casinos that accept real money to wager on real sporting events. However, this does not mean an online sportsbook’s address is only located on the internet. Any reputable online book will have a physical address located on its website along with a toll-free telephone number you can use to call them and ask questions if needed. Some will even have an FAQ you can review to help you feel more comfortable about betting there.
