Sportsbook Licensing and Regulation: What Bettors Should Know

Sportsbook licensing is old plumbing. The decade you are looking at tells you which pipes are which.

I was wrenching on Bally 831 machines when sports betting was still illegal in every state except Nevada. I am not a lawyer. But I watched the industry evolve from the adjacent seat, and I want to walk you through how the current licensing picture got the way it is. Move through time with me. Every era bolted something onto the machine that is still there.

0x011931: The Nevada Foundation

Nevada legalized most forms of gambling in 1931, including sports betting, though the sports side was a sleepy adjunct to casino gambling for decades. The Nevada State Gaming Control Board was not established until 1955, and the Nevada Gaming Commission not until 1959. The regulatory structure built in those years, two-tiered with a board handling investigations and a commission handling licensing, became the template that later jurisdictions copied.

Key principle bolted in here: the licensee is responsible for the conduct of the business, and the license can be suspended or revoked if the licensee fails to maintain suitability. That principle is unchanged in 2026.

0x021961: The Wire Act

Congress passed the Federal Wire Act in 1961. The language prohibited use of wire communication facilities for the transmission of bets or wagers across state lines on sporting events. This was aimed at organized crime, not at ordinary bettors, but the statute's plain text created a federal barrier to interstate sports wagering that stood for forty years before anyone seriously tested it in court.

The Wire Act still applies. Modern online sportsbooks are licensed on a state-by-state basis precisely because the Wire Act, as interpreted in a 2011 Department of Justice memo and subsequent litigation, continues to prohibit interstate wagering on sports. Cross-state betting pools are built around the Wire Act, not in violation of it.

0x031978: Atlantic City Opens

New Jersey legalized casino gambling in Atlantic City through the Casino Control Act of 1977, with the first casino opening in 1978. The Casino Control Commission was the licensing body. The Division of Gaming Enforcement was the investigative arm. Sports betting was not part of the initial Atlantic City framework. It was prohibited federally by PASPA, which had not yet been passed but was already in the air.

Atlantic City's contribution to the sportsbook licensing picture was procedural. The Atlantic City framework invented most of the modern paperwork: patron dispute resolution procedures, responsible gambling signage requirements, compliance staffing minimums, and annual audit protocols. Those documents now sit inside every state sportsbook license application.

0x041992: PASPA

The Professional and Amateur Sports Protection Act became federal law in 1992. It prohibited state-sanctioned sports betting in all states except those that had already authorized some form of it, which meant Nevada kept its sportsbooks, Delaware kept a limited parlay card product, and a handful of other states had narrow carveouts.

For twenty-six years, this was the law. Sports betting licensing in the United States was effectively a Nevada-only enterprise for commercial operators. Everyone else ran offshore, in gray-market jurisdictions like Antigua and later Costa Rica and Curacao. The offshore sportsbooks that Americans bet with during this period had licenses, real ones in those countries, but the licenses had no practical weight inside the United States.

0x052006: UIGEA

The Unlawful Internet Gambling Enforcement Act of 2006 did not criminalize the act of betting online. It criminalized the financial transactions associated with unlawful internet gambling. Payment processors got nervous. A lot of offshore books stopped accepting American credit card deposits. The ecosystem thinned out for several years before adapting.

UIGEA also carved out specific exceptions: state lotteries, horse racing, and intrastate fantasy contests. Those exceptions are what made the daily fantasy sports industry possible from 2009 onward, which in turn built the customer database that became the modern DraftKings and FanDuel user bases.

0x062018: Murphy v. NCAA

The Supreme Court struck down PASPA in May 2018. New Jersey, which had fought the case, authorized full sports betting within weeks. Other states followed at different paces. Delaware, West Virginia, Mississippi, New Mexico, Pennsylvania, and Rhode Island all authorized sports betting in the back half of 2018.

The licensing model that emerged is state-by-state. Each state issues its own sportsbook licenses, imposes its own tax rates, sets its own rules on which events can be bet and which markets are available. A sportsbook that wants to operate in New Jersey, Pennsylvania, and New York must hold three separate licenses, comply with three separate regulatory schemes, and pay three separate tax rates. There is no federal sports betting license.

This is why the same company has meaningfully different product offerings across state lines. New Jersey allows betting on college basketball involving in-state teams. New York does not. Pennsylvania allows player prop bets on college football. Some other states do not. These are regulatory variations, not commercial ones.

0x072019 Through 2023: Expansion

Most states that authorized sports betting in this period picked one of two broad licensing models. The multiple-operator model allows several commercial sportsbooks to hold licenses within the state. The single-operator model grants an exclusive license to one operator, typically the state lottery or a single contracted vendor.

New York's launch in January 2022 under the multiple-operator model with a 51 percent tax rate is the extreme case. Nine operators compete at a tax rate that erases most of their margin. The model is commercially painful but produced over a billion dollars in tax revenue within eighteen months of launch, which is the number state legislators pay attention to.

0x08What The Bettor Actually Needs To Know In 2026

If you are betting on a licensed US sportsbook, the license is a state license, and the protections that come with it are state-specific. The state gaming regulator will adjudicate disputes. The state has identity verification and anti-money-laundering requirements the operator has passed. The state has tax obligations you may or may not owe, depending on your jurisdiction.

If you are betting on an offshore sportsbook that accepts US players, the license is foreign, and enforcement against the operator from a US consumer protection standpoint is limited to nonexistent. Offshore books can and do function well for many years. They can also freeze accounts, change terms, and delay payouts without any meaningful recourse available to the American bettor. The machine is running, but no one onshore is under the cabinet with a service flashlight.

Regulation is not sexy. Regulation is bolts and gaskets. A sportsbook that has the right bolts is one you can trust to pay when it loses. A sportsbook without them is a product you are using at your own risk. Decide which one you are at, and plan accordingly.
