Online Sports Betting Over the past decade, online sports betting has become one of the fastest-growing sectors within the broader gambling industry in the United States. Fueled by legislative changes, technological advancements, and shifting public attitudes, the landscape of sports wagering has transformed dramatically. Today, millions of Americans can legally place bets on their favorite teams, events, and outcomes all from the convenience of their smartphones or computers.
This article explores the legal framework, growth trends, popular platforms, and key considerations for bettors engaging in online sports betting in the US.
Legal Background and Regulation Online Sports Betting
For much of the 20th and early 21st centuries, sports betting in the United States was largely prohibited under the Professional and Amateur Sports Protection Act (PASPA) of 1992. This federal law effectively banned sports betting in most states, with a few exceptions like Nevada.
However, a landmark Supreme Court decision in May 2018 overturned PASPA, ruling it unconstitutional. This decision gave individual states the authority to legalize and regulate sports betting within their borders.
As of 2025, over 30 states have legalized sports betting, with many offering online and mobile options. States like New Jersey, Pennsylvania, Michigan, and Illinois have become leaders in the online betting space, while others, such as California and Texas, are still debating legislation.
