A Breakdown of U.S. Gambling Law Changes Over the Last Decade

Over the past decade, the landscape of gambling in the United States has undergone significant shifts. These changes are largely driven by evolving public attitudes, advances in technology, and the desire to capture new revenue streams.

This period has been marked by major legislative actions at both federal and state levels, particularly around sports betting, online gambling, and casino expansion.

Here’s a breakdown of the most pivotal changes in U.S. gambling laws over the last 10 years.

1. The Repeal of PASPA and the Explosion of Sports Betting (2018)

One of the most impactful legal changes in the last decade was the Supreme Court’s decision in Murphy v. NCAA in May 2018, which struck down the Professional and Amateur Sports Protection Act (PASPA). Enacted in 1992, PASPA effectively banned sports betting nationwide, except in a few states like Nevada. The repeal of PASPA opened the door for states to legalize and regulate sports betting as they saw fit.

In the wake of this decision, states have moved swiftly. As of 2024, over 30 states have legalized sports betting, either online, at physical sportsbooks, or both. States like New Jersey, which spearheaded the legal challenge to PASPA, have become major hubs for sports wagering, generating significant tax revenue.

2. The Rise of Online Gambling and iGaming

Online gambling, often referred to as iGaming, has also seen major developments in the last decade. Although online casino games and poker were generally illegal or unregulated in the U.S. until recently, several states have moved to legalize and regulate these activities.

The groundwork was laid in 2011 when the U.S. Department of Justice (DOJ) reinterpreted the Federal Wire Act of 1961, stating that it applied only to sports betting and not to other forms of online gambling. This interpretation encouraged states to explore legal online gambling options.

Since then, states like New Jersey, Pennsylvania, and Michigan have launched regulated iGaming markets, offering online poker, slots, and table games. These states have seen strong demand, with New Jersey’s online gaming market generating billions in revenue since it was legalized in 2013.

3. Fantasy Sports and Daily Fantasy Sports (DFS)

Another major shift has been the rise of Daily Fantasy Sports (DFS), which gained significant popularity in the early 2010s. Companies like DraftKings and FanDuel led the charge, offering fantasy sports contests that operate under a skill-based game classification, rather than traditional gambling.

However, DFS did face legal challenges, with some states initially banning the practice. In response, companies and lobbyists pushed for legislation to legalize and regulate DFS, often in exchange for consumer protections and tax contributions. By 2024, DFS is legal in most U.S. states, although the legal frameworks can vary from state to state.

4. State-by-State Casino Expansion

Casino gambling has expanded dramatically across the U.S. in the last decade. Many states that previously did not have commercial casinos have legalized them, spurred by the potential for new revenue sources. States such as Massachusetts, New York, and Illinois have authorized new casino licenses, often in major metropolitan areas.

In some states, the casino expansion has taken the form of tribal gaming compacts, where Native American tribes negotiate agreements with state governments to operate casinos. Tribal casinos are subject to the federal Indian Gaming Regulatory Act (IGRA) of 1988, but recent years have seen new compacts signed, expanding both the number and the types of games offered at these facilities.

5. Lotteries and the Introduction of Online Sales

Another significant change has occurred in state-run lotteries, which have traditionally been restricted to physical ticket sales. Over the past decade, several states have moved to allow online lottery ticket sales. States like Michigan, Illinois, and Georgia now allow residents to purchase lottery tickets, including multi-state games like Powerball and Mega Millions, through digital platforms.

This move toward online lottery sales has helped state lotteries reach a younger, more tech-savvy audience, while also generating additional revenue. The pandemic in 2020 accelerated this trend as states looked for ways to keep revenue streams flowing despite disruptions to traditional retail outlets.

6. Challenges with Federal Online Gambling Regulation

While many states have embraced online gambling, there have been persistent legal challenges at the federal level, particularly regarding the interpretation of the Wire Act. In 2018, the DOJ under the Trump administration reinterpreted the Wire Act, stating that it applied to all forms of gambling, not just sports betting. This led to significant uncertainty for online gambling operators.

However, in 2021, a federal appeals court ruled in favor of states like New Hampshire, stating that the Wire Act only applies to sports betting. This decision has reaffirmed the ability of states to regulate online gambling within their borders without federal interference.

7. Social and Ethical Concerns: Responsible Gambling Initiatives

As gambling laws have become more liberalized across the U.S., concerns about problem gambling and addiction have also grown. In response, many states have strengthened their responsible gambling measures. Some states have established self-exclusion programs, requiring operators to provide tools for players to limit their spending or take breaks from gambling.

States with legal online gambling are often required to allocate a portion of gambling revenues to fund addiction treatment and education programs. Additionally, as sports betting and online gambling have gained popularity, the industry has adopted more data-driven player protection systems, designed to detect at-risk behaviors and offer interventions.

Conclusion

The last decade has been transformative for gambling in the U.S. From the Supreme Court’s landmark decision on sports betting to the rise of online gambling and daily fantasy sports, legislative changes have reshaped the industry. As more states continue to explore new forms of gambling—both online and offline—the next decade is likely to bring even more innovation, regulation, and debate about the role of gambling in American society. For players, operators, and regulators alike, staying informed about these changes is critical as the legal landscape continues to evolve.
