Since the U.S. Supreme Court cleared the way for state-level sports betting in 2018, Americans have legally wagered over $668.6 billion on sports, generating more than $12 billion in state tax revenue, according to recent data. The milestone underscores the rapid expansion of the regulated sports betting market and its growing fiscal importance for state governments.

Nearly eight years after the Supreme Court’s landmark decision to strike down the federal ban on sports betting, the industry has reached a staggering cumulative handle of $668,603,360,342 in legal wagers. The data, compiled by industry analysts and reported by MarketWatch, highlights the sustained growth of legal sportsbooks across the states that have chosen to regulate the activity.
State governments have collected over $12 billion in tax revenue from sports betting operations during that period. This revenue stream has become an increasingly important source of funding for education, infrastructure, and problem gambling programs in many states. The tax contributions vary widely by jurisdiction, with some states imposing higher tax rates on sportsbook revenue than others.
The legal sports betting landscape has evolved dramatically since May 2018, when the Supreme Court ruled in Murphy v. National Collegiate Athletic Association that the Professional and Amateur Sports Protection Act (PASPA) was unconstitutional. That decision allowed individual states to legalize and regulate sports betting within their borders. As of mid-2026, more than 35 states plus Washington, D.C., have legalized sports betting in some form, with several others considering legislation.
The $668.6 billion handle does not include wagers placed through illegal offshore books or unregulated operators, which industry observers estimate could represent a significant additional volume. Regulatory efforts continue to focus on curbing the black market while expanding legal options for consumers.

Expert Insights
The $668.6 billion cumulative handle since 2018 suggests that legal sports betting has become a permanent fixture in the U.S. consumer landscape. However, industry observers caution that growth rates may moderate as more states reach maturity and the "low-hanging fruit" of new market launches is harvested.
Tax revenue of $12 billion represents a meaningful, if still small, contribution to overall state budgets. For comparison, total state tax collections in the U.S. exceed $1 trillion annually. Still, for individual states like New Jersey, Pennsylvania, and New York, sports betting taxes have provided tens or hundreds of millions of dollars per year for specific programs.
Investors considering exposure to the sports betting sector should note the highly competitive nature of the industry. Operators spend heavily on customer acquisition, which can pressure margins in the short term. The path to profitability varies by company, with some reporting positive EBITDA while others continue to invest for market share.
Regulatory risk remains a factor. While no state appears likely to reverse legalization, future changes in tax rates, advertising restrictions, or licensing fees could alter the competitive dynamics. Additionally, technological developments such as in-play betting, cashless wagering, and integration with media platforms could shape the next growth phase.
From an investment perspective, the sports betting ecosystem encompasses not only operators but also technology providers, data analytics firms, and media companies that benefit from increased engagement. The long-term trajectory will depend on further state expansions, responsible gambling measures, and the ability of operators to sustain customer loyalty in a crowded market.
