Sports betting has undergone a dramatic transformation in the United States since 2018. The answer to whether sports betting is legal in the US is nuanced: it is legal at the federal level, but each state determines its own regulations, resulting in a patchwork of laws that vary significantly across the country. While some states have embraced fully regulated markets, others maintain restrictions or prohibit the activity entirely. This guide provides a comprehensive breakdown of the current legal landscape, helping you understand which states permit sports betting, the types of wagers available, and what regulations bettors must navigate.

The Legal Landscape: How We Got Here
Before 2018, the Professional and Amateur Sports Protection Act (PASPA) effectively prohibited sports betting nationwide, with limited exceptions for a few states that had existing lottery systems. This federal law, passed in 1992, made it illegal for states to authorize sports betting operations, creating a blanket prohibition that lasted over two decades.
The turning point came in May 2018 when the Supreme Court ruled in Murphy v. National Collegiate Athletic Association that PASPA was unconstitutional. The 6-3 decision held that the federal government was overstepping its authority by compelling states to maintain prohibitions on sports betting, violating the anti-commandeering doctrine. This ruling did not legalize sports betting nationwide; instead, it returned the decision to individual states, effectively ending the federal prohibition.
Evolution of US Sports Betting
- 1992: PASPA signed into law, prohibiting sports betting nationwide
- 2012: Delaware became the first state to offer limited parlay betting on NFL games after receiving a PASPA exemption
- 2018: Supreme Court strikes down PASPA in Murphy v. NCAA decision
- 2018: New Jersey launches first legal post-PASPA sports betting operation
- 2024: Over 35 states plus Washington D.C. have operational legal sports betting
The ruling unleashed a wave of legislative activity. States moved quickly to capitalize on potential tax revenue and address consumer demand for legal alternatives to offshore betting platforms. According to the American Gaming Association, the legal sports betting industry generated over $14 billion in revenue in 2023 alone, demonstrating the massive market that has developed since legalization.
Current State of Legal Sports Betting in America
As of 2024, sports betting is legal and operational in more than 35 states plus Washington D.C., with additional states considering legislation. The legal landscape divides into three categories: states with fully operational markets, states with limited or restricted options, and states where sports betting remains prohibited.
States with legal sports betting have established regulatory frameworks through their state legislatures and gaming commissions. These regulatory bodies oversee licensing, ensure operator compliance, collect tax revenue, and protect consumers. The regulatory environment varies significantly—some states maintain monopolies operated by state lotteries, while others allow multiple private operators to compete under licenses.
States with Legal Sports Betting (Selected):
| State | Launch Year | Operator Type | Key Regulator |
|---|---|---|---|
| Nevada | 1949* | Multiple private | Nevada Gaming Control Board |
| New Jersey | 2018 | Multiple private | Division of Gaming Enforcement |
| Pennsylvania | 2018 | Multiple private | Pennsylvania Gaming Control Board |
| Illinois | 2020 | Multiple private | Illinois Gaming Board |
| Michigan | 2021 | Multiple private | Michigan Gaming Control Board |
| New York | 2022 | Multiple private | New York State Gaming Commission |
| Ohio | 2023 | Multiple private | Ohio Casino Control Commission |
| Massachusetts | 2023 | Multiple private | Massachusetts Gaming Commission |
Nevada had legal sports betting before PASPA due to grandfather provisions
States where sports betting remains illegal include states like Utah and Hawaii, where religious or cultural factors have prevented legalization efforts. Other states have considered legislation but not yet passed enabling laws.
State-by-State Breakdown and Key Differences
The regulatory framework varies dramatically across legal states, creating what industry experts describe as a “patchwork” system. Understanding these differences is essential for anyone looking to place bets legally.
Tax Rates and Revenue Sharing
States impose varying tax rates on sports betting revenue, which directly impacts operator profitability and, consequently, the odds and promotions available to bettors. New York imposes one of the highest tax rates at 51% on online betting revenue, while Nevada’s tax rate is considerably lower at 6.75%. These differences affect how competitive each state’s market is.
According to the National Conference of State Legislatures, tax rates range from as low as 6% in states like Nevada to over 50% in New York. Higher tax rates often result in less attractive odds for consumers, as operators must maintain profitability despite increased regulatory costs.
Betting Restrictions by State
Different states permit different types of wagers. Most legal states allow the full range of betting options, including:
- Moneyline bets (picking the winner)
- Point spreads (betting on margin of victory)
- Over/under totals (betting on combined score)
- Parlays (combining multiple bets)
- Props and futures (individual player or season outcomes)
- Live in-game betting
However, some states maintain restrictions on certain bet types. For example, some states prohibit betting on collegiate events involving in-state teams, while others restrict player prop bets. Vermont, which launched legal betting in 2024, initially restricted certain prop bets before revising its regulations.
Online vs. In-Person Betting Requirements
One of the most significant developments since PASPA’s overturning has been the rise of online and mobile sports betting. Unlike the traditional casino-based model, mobile betting allows consumers to place wagers from anywhere within state boundaries using smartphones or computers.
States with Online Sports Betting:
Most legal states now offer both retail (in-person) and online/mobile betting options. States like New Jersey, Pennsylvania, and Michigan have robust online markets that generate the majority of total betting revenue. Mobile betting accounted for approximately 90% of all sports bets placed in New Jersey in 2023, according to the New Jersey Division of Gaming Enforcement.
States Requiring In-Person Registration:
Some states initially required bettors to register in person at a casino or retail location before being able to bet online. This requirement has been relaxed or eliminated in most states, though a few maintain restrictions:
- Montana requires in-person registration at licensed locations
- New Hampshire requires in-person registration for some operators
- Washington D.C. initially required in-person registration but has since expanded options
Geographic Restrictions:
Federal law requires that online sports bets originate from within state lines where betting is legal. Technology known as geo-fencing verifies bettor locations through IP addresses and GPS data. This means that even if you are legally permitted to bet in a particular state, you must be physically present within that state’s boundaries to place a wager legally.
This geographic restriction has significant implications for travelers and those living near state borders. For UK readers considering betting on US sports while visiting America, understanding these geo-restrictions is crucial—simply being a UK citizen does not grant betting rights across all US states.
Key Regulations and Consumer Protections
Each state that has legalized sports betting has established its own regulatory framework to protect consumers and ensure market integrity. Understanding these regulations helps bettors identify legal operators and avoid illegal offshore platforms.
Licensing Requirements:
Legal sports betting operators must obtain licenses from state gaming regulators. These licenses require:
- Background checks on ownership and key personnel
- Financial stability demonstrations
- Technical compliance with state gaming regulations
- Responsible gambling program implementation
- Data security and privacy protections
Unlicensed operators, including many offshore websites, operate illegally in the US and offer no consumer protections. The Federal Bureau of Investigation and state attorneys general have increased enforcement actions against illegal operators, but consumers should still exercise caution.
Responsible Gambling Measures:
Legal states require operators to implement responsible gambling tools, including:
- Deposit limits
- Spending and time tracking
- Self-exclusion programs
- Cooling-off periods
- Underage verification
According to the National Council on Problem Gambling, these mandatory safeguards help identify and assist individuals struggling with gambling addiction. All licensed operators must provide resources for problem gambling support and cooperate with state-mandated self-exclusion programs.
Consumer Protections:
Legal sports betting offers significant advantages over illegal alternatives. Licensed operators must:
- Maintain segregated player funds
- Provide dispute resolution mechanisms
- Report suspicious betting activity
- Ensure fair odds and accurate payouts
- Protect personal and financial data
The UK Gambling Commission has established similar protections for UK-based operators, though the specific mechanisms differ between jurisdictions.
What International Bettors Need to Know
For UK residents and other international visitors interested in US sports betting, several important considerations apply. The legal framework discussed throughout this guide applies to betting activities occurring within US state boundaries—international laws and regulations differ significantly.
Betting as a US Visitor:
If you are visiting the US from the UK, you can legally place sports bets only in states where betting is legal and while physically present within those states. Your UK citizenship does not authorize betting in states where it remains prohibited. Additionally, you must be of legal betting age (typically 21 in most US states) and comply with state-specific identification requirements.
UK-Based Betting Options:
UK residents have access to numerous licensed operators offering odds on US sports through legal, regulated platforms. UK gambling laws differ substantially from US state regulations, and UK-licensed operators can legally offer betting services to UK residents without geo-restrictions for US-based events. These platforms operate under UK Gambling Commission oversight and provide consumer protections established under UK law.
Cross-Border Considerations:
Betting on US sports from outside the US through licensed US operators would typically violate those operators’ terms of service and potentially constitute illegal gambling under US law. Conversely, UK residents using UK-licensed operators face no such restrictions. For most international bettors, using appropriately licensed platforms in their home jurisdiction provides the most straightforward legal option.
The Future of US Sports Betting
The US sports betting market continues to evolve rapidly, with new states launching operations, existing markets expanding, and federal discussions about potential nationwide standards.
Pending Legislation:
Several states continue to consider sports betting legalization. States like Missouri and South Carolina have repeatedly considered legalization bills without passing enabling legislation. According to the American Gaming Association, additional states could legalize sports betting within the next two to three years, potentially bringing legal options to states representing 90% of the US population.
Federal Considerations:
While the 2018 Supreme Court decision granted states authority over sports betting, Congress retains jurisdiction over interstate commerce and could theoretically establish federal standards. Industry stakeholders have expressed mixed views on potential federal legislation—some favor uniform national regulations to simplify compliance, while others prefer maintaining state-level control.
Market Maturation:
The industry is experiencing consolidation, with major operators acquiring smaller competitors and media companies entering partnerships with sportsbooks. This maturation suggests the market is moving beyond rapid expansion toward established, sustainable operations.
Frequently Asked Questions
Can I bet on sports in all US states?
No, sports betting is not legal in all US states. While over 35 states have legalized and launched sports betting operations, several states—including Utah, Hawaii, and Alaska—have not passed enabling legislation. Additionally, some states have very limited options or only permit in-person betting at specific casino locations.
What is the legal age for sports betting in the US?
The legal age for sports betting varies by state. In most states, you must be 21 years old to place sports bets. However, a few states, including Montana and New Hampshire, allow betting at age 18. Always verify the specific requirements for the state where you intend to bet.
Can I use my UK sportsbook account while in the US?
No, UK-licensed sportsbooks generally do not accept bets placed from the US on US-based sports betting platforms. If you are visiting the US and want to bet legally, you must use a licensed operator in the state where you are physically located. UK sportsbooks can still offer betting on US sports to customers in the UK, but they cannot accept bets from US soil.
Is online sports betting legal in the US?
Online sports betting is legal in most states that have legalized sports betting. However, you must be physically located within a state where betting is legal to place online wagers. Geo-fencing technology verifies your location, and attempting to bypass these restrictions violates operator terms and potentially federal law.
Do UK taxes apply to winnings from US sports betting?
UK tax laws generally apply to UK residents regardless of where gambling occurs. However, UK tax on gambling winnings is structured differently—winnings are not typically taxed as income, though there may be implications depending on the nature and frequency of your betting activities. Consult a tax professional for advice specific to your situation.
Are offshore sportsbooks legal for US residents?
No, offshore sportsbooks operating without US licenses are not legal for US residents to use. Despite marketing to American consumers, these platforms violate US federal and state laws. Using licensed, domestic operators provides consumer protections and ensures compliance with applicable laws.
