How U.S. Golf Betting Regulations Have Evolved, According to Betzonic

The legal landscape surrounding sports wagering in the United States has undergone a dramatic transformation over the past three decades, and golf betting has been caught squarely in the middle of that shift. What was once a largely underground activity confined to informal wagers among friends or offshore accounts has gradually moved into a regulated, taxed, and increasingly mainstream form of entertainment. Understanding how that transition unfolded — and what it means for golf bettors specifically — requires tracing the regulatory milestones that shaped the current environment.

The PASPA Era and Its Constraints on Golf Wagering

For much of the modern era of American sports betting, the Professional and Amateur Sports Protection Act of 1992 — commonly known as PASPA — defined the outer boundaries of what was legally permissible. The law effectively granted Nevada a near-monopoly on single-game sports wagering, while allowing limited carve-outs for Oregon, Delaware, and Montana, which operated sports lottery-style products rather than traditional sportsbooks. Under this framework, a bettor in New York or Florida who wanted to place a wager on the Masters Tournament had no legal domestic option outside of Nevada. The offshore market, populated by Caribbean and European-licensed operators, filled that vacuum throughout the 1990s and 2000s, with millions of Americans placing bets through sites that technically operated outside U.S. jurisdiction.

During the PASPA years, golf occupied a peculiar position in the betting ecosystem. Unlike football or basketball, which generated enormous handle through parlay cards and point spreads, golf’s wagering appeal was more niche. The format of the sport — 72-hole stroke play with fields of 150 or more competitors — lent itself to outright winner markets and each-way betting structures that were more familiar to British and European bookmakers than to American operators. Nevada sportsbooks did offer golf odds, primarily on major championships like the U.S. Open and The Open Championship, but the volume was modest compared to team sports. This relative obscurity actually shielded golf betting from some of the political scrutiny that NFL wagering attracted, but it also meant the sport received less regulatory attention when reform discussions began in earnest.

The Murphy v. NCAA Decision and Its Immediate Aftermath

The Supreme Court’s 2018 ruling in Murphy v. NCAA fundamentally altered the American sports betting landscape by striking down PASPA as an unconstitutional commandeering of state legislative authority. The decision, handed down in May 2018, did not legalize sports betting outright — rather, it returned the question of legalization to individual states. New Jersey, which had been the plaintiff in the case, launched legal sports betting within days of the ruling. By the end of 2018, seven states had active legal markets. By 2023, that number had grown to over 30 states plus the District of Columbia, representing a seismic shift in both regulatory philosophy and market scale.

For golf specifically, the post-Murphy environment created new opportunities and new complications simultaneously. On the opportunity side, regulated sportsbooks in states like New Jersey, Pennsylvania, and Colorado began offering far more sophisticated golf betting markets than had previously been available domestically. Outright winner odds, head-to-head matchups, round-by-round scoring markets, and live in-play wagering all became accessible to bettors in legal jurisdictions. The American Gaming Association estimated that handle on golf events grew substantially in the years following legalization, with major championships like The Masters and the PGA Championship generating tens of millions of dollars in wagers through licensed U.S. operators. Resources tracking the development of these markets, such as betzonic.com/golf-betting-sites/, reflect how rapidly the licensed operator landscape expanded to serve demand that had previously been routed offshore.

On the complication side, the fragmented state-by-state regulatory model created significant inconsistencies in what golf betting products were available depending on where a bettor happened to be located. A resident of New Jersey could access live in-play markets during a Sunday final round at Augusta, while a bettor in Utah — where sports wagering remains prohibited — had no legal option at all. This patchwork structure has remained one of the defining characteristics of American sports betting regulation, and golf bettors have had to navigate it accordingly.

State-Level Regulation and Golf-Specific Market Development

As individual states developed their regulatory frameworks after 2018, several distinct approaches emerged that affected how golf betting markets were structured and offered. New Jersey’s Division of Gaming Enforcement became an early model for other states, establishing licensing requirements, responsible gambling mandates, and integrity monitoring protocols that operators had to satisfy before launching. Pennsylvania took a different approach, imposing a relatively high 36 percent tax rate on online sports betting revenue, which affected operator margins and, in turn, influenced the odds and promotions available to bettors. Nevada, despite no longer being the only legal market, retained its status as a regulatory benchmark given its decades of operational experience.

Golf presented specific challenges for integrity monitoring that regulators had to address. The sport’s individual format, combined with the global nature of its professional tours, meant that suspicious betting patterns could originate from anywhere in the world. The PGA Tour entered into official data partnerships with several licensed operators and integrity monitoring firms, most notably IMG Arena, to provide real-time scoring data and flag anomalous wagering activity. These partnerships represented a significant evolution from the pre-legalization era, when the Tour had largely opposed sports betting expansion. By the early 2020s, the Tour’s position had shifted toward pragmatic engagement with the regulated market, recognizing that legal betting generated fan engagement and viewership data that had commercial value.

Betzonic, which monitors developments in the golf betting market, has documented how the range of available markets expanded significantly between 2019 and 2024. Early post-PASPA golf betting was dominated by simple outright winner markets, but licensed operators gradually introduced more complex products including three-ball betting, nationality-based markets, cut-making propositions, and hole-by-hole scoring options during live play. This product evolution mirrored what European bookmakers had offered for years, reflecting the influence of British-licensed operators — including DraftKings, FanDuel, and BetMGM’s parent companies — who brought established golf betting frameworks into the American market.

Federal Proposals and the Question of National Standards

Despite the rapid expansion of state-level regulation, the question of whether the federal government should establish national standards for sports betting has remained unresolved. Several proposals have circulated in Congress since 2018, typically centered on three areas: a federal integrity fee or royalty paid to sports leagues, uniform consumer protection standards across all states, and a national framework for problem gambling resources. None of these proposals has advanced to a floor vote in either chamber, largely because the states that have already established successful regulatory regimes have little incentive to cede authority to a federal body.

For golf betting, the absence of federal standards has practical consequences. The PGA Tour’s data deals with licensed operators are negotiated individually, meaning that the quality and speed of data available to sportsbooks — and therefore to bettors — varies depending on which operator a bettor uses and in which state they are located. In-play golf betting, which depends heavily on real-time scoring data, is particularly sensitive to these variations. A bettor attempting to wager on a player’s score on a specific hole during a live broadcast may encounter latency differences that create material advantages or disadvantages depending on their platform and jurisdiction.

The Professional Golfers’ Association of America, distinct from the PGA Tour, has also engaged with the regulated betting market in ways that differ from its counterpart organization. The PGA of America oversees club professionals and major championships including the PGA Championship and the Ryder Cup, and its approach to betting partnerships has evolved separately. The Ryder Cup, in particular, generates unusual betting interest because its match play format and team structure create wagering markets that differ significantly from standard stroke play events. Regulatory treatment of Ryder Cup betting has varied across states, with some jurisdictions treating it as a standard golf event and others applying additional scrutiny given its international format and the participation of players from outside the United States.

The trajectory of U.S. golf betting regulation over the past three decades reflects a broader national reckoning with the role of wagering in sports culture. From the restrictive PASPA framework that pushed activity offshore, through the landmark Murphy ruling that returned authority to states, to the current fragmented but functional multi-state marketplace, the evolution has been neither linear nor uniform. What has emerged is a system that provides legal access to a wide range of golf betting markets for a majority of American adults, while leaving significant regulatory gaps and inconsistencies that continue to shape the bettor experience. As more states consider legalization and existing markets mature, the structural questions around data rights, integrity monitoring, and consumer protection will likely define the next phase of regulatory development — with golf, given its global profile and unique format, remaining a meaningful test case for how those questions get answered.
