The legal landscape in the United States

Sports betting is legal in most US states as of 2026. The federal regime that prohibited state-by-state sports betting outside Nevada (PASPA) was struck down by the Supreme Court in 2018, opening the door for states to set their own policies. The result is a patchwork. The basics are stable; the details vary. Verify the rules in your jurisdiction before placing a bet.

The post-PASPA framework

Before 2018, the Professional and Amateur Sports Protection Act (PASPA) prohibited most sports betting outside Nevada. The Supreme Court struck down PASPA in May 2018 (Murphy v. NCAA), finding the federal restriction unconstitutional. Sports betting policy reverted to the states.

Since 2018, more than 35 states plus DC have passed legislation legalizing sports betting in some form. Most legalizing states allow online and retail (in-person) sports betting. Some allow only retail. A few allow betting only at tribal casinos. A small number prohibit sports betting entirely.

What the legalizing framework typically requires

• 21 years of age minimum (sometimes 18, varies by state).
• Geographically located within the legal state at the time of the bet (online sportsbooks use geolocation enforcement).
• Identity verification (KYC) before account funding and withdrawals.
• Tax reporting on wins above defined thresholds (usually $600 with 300:1 odds, plus broader regulations on aggregate wins).

Online books actively enforce geolocation. Crossing a state border with an open app session typically locks bet placement until you re-verify. Crossing back keeps prior bets active but may restrict new ones depending on state rules.

Where it is legal as of 2026

The list of states with legalized sports betting changes regularly. The WagerBird sportsbooks page maintains a current state-by-state status reference. See /sportsbooks for the current map.

States historically lagging behind have included California, Texas, Georgia, and a handful of others. Status changes year over year as state legislatures act. Always verify the current status in your state before assuming.

Tribal vs commercial

Some states allow sports betting only at tribal casinos. Tribal sportsbooks operate under federal Indian Gaming Regulatory Act (IGRA) rules in addition to state-level compacts. The regulatory framework is similar to commercial sports betting in most consumer-facing respects, but the licensing and operational details differ.

Offshore books

Offshore sportsbooks (operating outside the US, often in Costa Rica, Curacao, or other jurisdictions) accept US bettors despite US-side legality questions. The legal status varies by state. Most US states do not actively prosecute individual bettors for placing bets at offshore books, but the books themselves operate outside US regulatory protection. Funds, payouts, and dispute resolution are not enforced by US regulators.

DFS and props at the state level

Daily fantasy sports (DFS) is legal in most US states, including states where traditional sports betting is not. DFS-style player-prop products (PrizePicks, Underdog) operate in this category. The legal classification is contested in some states; the consumer-facing products look like sportsbooks but are technically structured differently.

Some states have begun to regulate DFS-style products as sports betting, with corresponding consequences for which products operate where. Verify before assuming a DFS-style product is legal in your state.

Tax compliance

All sports betting winnings are taxable income at the federal level. Books issue W-2G forms for wins meeting reporting thresholds. State tax treatment varies. Casual bettors usually report winnings as income but face limitations on offsetting losses against wins. Professional bettors (those whose betting rises to the level of trade or business) face different rules.

Detailed treatment is in taxes and record keeping. Consult a tax professional for advice specific to your situation.
