Are Offshore Sportsbooks Safe to Use?

No. An offshore sportsbook takes bets from people in the United States without a license from any US state, so nothing that protects a customer at a licensed book applies to you there. If it holds up a withdrawal, voids a winning ticket after the fact, or leaks your ID and bank details, there is no state gaming regulator whose job is to make it right. You would be relying on the goodwill of a company that is already ignoring the law where you live.

That is the whole risk in one sentence. Below: what these sites are, why they can't be licensed here, and what goes wrong for customers.

This guide describes risks; it isn't legal advice, and we don't name or link to any offshore site.

What counts as an offshore sportsbook?

An offshore book is a betting site that accepts wagers from US customers without holding a license from the state the customer is in. It usually runs from outside the country. The American Gaming Association's August 2025 report describes these as sites that "take wagers from U.S. consumers but are not licensed to operate in the U.S. or to accept bets placed from the U.S.," noting that some do hold licenses in places like Malta or Curaçao.

That foreign license is the most common source of confusion. It permits a company to operate under that jurisdiction's rules. It gives it no permission to take a bet from someone in Ohio. A licensed US sportsbook needs a license from each state it serves, and the bet has to happen inside that state.

Why can't they get a US license?

Two federal laws do most of the work.

The Wire Act makes it a crime for anyone "engaged in the business of betting or wagering" to knowingly use wire communications to transmit bets in interstate or foreign commerce. A site in another country taking a bet from a phone in Texas is the textbook case.

The Unlawful Internet Gambling Enforcement Act carves out an exception for online betting, but only if the bet is "initiated and received or otherwise made exclusively within a single State" whose law authorizes it and requires age and location verification. Legal US apps are built around that exception: a license in each state, bets received inside that state, and a location check before wagers are accepted. A site serving the whole country from abroad can't fit through it.

States can also act on their own. On April 7, 2026, the Michigan Gaming Control Board said it had issued cease-and-desist orders to 45 offshore gambling operators, sportsbooks and online casinos among them, in the preceding four months, after investigations confirmed each was accepting wagers or offering casino-style games to Michigan residents without a state license. The board warned that operators who ignore the orders face escalation to further civil and criminal enforcement.

How big is the offshore market?

The AGA's report estimates that Americans wagered $84.0 billion with bookies and offshore sportsbooks over a year, generating $5.0 billion in revenue. That implies an average hold of $5.0 ÷ $84.0 = about 6% of every dollar bet. The same report estimates the illegal share of all US sports betting fell from 36% in 2022 to 24%.

Treat those as estimates, not measurements. They come from a survey of 2,454 adults extrapolated nationally, and the AGA is the trade group for licensed operators, which have an obvious interest in the number being large. The direction is the defensible part, and it is mixed: the report estimates the illegal market still grew in dollars since 2022 (from about $3.8 billion to about $5 billion in revenue) while shrinking as a share of all sports betting as legal markets expanded.

What are the actual risks?

The Michigan board's April release lists them plainly: "unfair or manipulated games, withheld winnings, misuse of personal and financial data, and no meaningful avenue for dispute resolution." Taking those one at a time:

Nobody to complain to. At a licensed book, a dispute you can't resolve with the operator goes to the state. Pennsylvania's Gaming Control Board, for instance, runs a dedicated online-sportsbook complaint form, accepts filings within 30 calendar days of the incident, and assigns every complaint a case number and an investigator. New Jersey requires you to file with the operator first and attach its response when you escalate to the Division of Gaming Enforcement. An offshore customer has none of that. A foreign license, where one exists, points you to a foreign authority, not a US one.

Your balance is an unsecured loan. Money sitting in an offshore account is only as safe as the company holding it. If the site slows withdrawals, adds a new verification hurdle after you win, changes its terms, or disappears, there is no US regulator to order it to pay. Withheld winnings are on the Michigan board's list for a reason.

No required consumer protections. Licensed books have to do specific things. New Jersey's rules, for example, require verified identity data and an age-21 check before an account opens, and when a customer self-excludes, pending wagers must be voided within three days and cashable funds refunded within 90. Nothing obliges an offshore site to offer deposit limits, honor a self-exclusion, keep its games audited, or protect your data.

Your data goes with it. Signing up means handing over a name, address, date of birth and payment details to a company that is outside US data-protection and gaming rules. The Michigan board lists misuse of personal and financial data as a specific risk.

Isn't the better price worth it?

This is the argument people actually make, so run the numbers.

Say a legal book deals a side at -110 and an offshore site offers +105. Implied probabilities: 110 ÷ 210 = 52.38% at the legal book; 100 ÷ 205 = 48.78% offshore. On a true 50/50 bet, the offshore price looks about 3.6 points better.

Now add the chance you don't get paid. As decimal odds, -110 is 1.909 and +105 is 2.050. If q is the probability the offshore site actually pays you, the two bets are worth the same when 2.050 × q = 1.909, or q = 93.1%. In other words, a 6.9% chance of not getting paid wipes out the entire price advantage. And that understates the risk, because a site that stops paying doesn't just withhold one winning ticket. It withholds your entire balance.

Nobody can put a reliable number on that probability for a given site. That's the problem: at a licensed book the number is supposed to be close to zero because a regulator enforces it, and at an offshore book you are guessing.

If price is what you are after, compare legal books against each other. Prices on the same market differ between licensed books too. The Academy covers that in types of betting sites and, for getting money in and out of legal books, sportsbook deposits and withdrawals.

Am I breaking the law by using one?

We won't answer that for your situation; it depends on your state and it's a question for a lawyer. What we can say is narrower. The federal statutes above are written at the business: the Wire Act's text targets people "engaged in the business of betting or wagering." State laws vary, and states have been increasingly active against the operators. None of that changes the consumer picture. Even where a customer faces no legal exposure at all, they are still using a site no US regulator will help them with.

How do I check that a book is licensed?

Use your state regulator's list of licensed operators, not the site's own claims. The Michigan board tells residents to confirm a platform appears on its official list "before registering or depositing funds," and to report suspected illegal sites by emailing MIGamblingTip@michigan.gov or calling 1-888-314-2682. Every legal state publishes an equivalent list. Our guide to where sports betting is legal lists which states have licensed online books at all, and how sports betting is regulated explains the complaint route once you're with one.
