Sports Betting Age Requirements — 18 or 21 Depending on Your State

Most states set the sports betting age at 21. A handful allow wagering at 18. Where you stand depends entirely on where you physically are when you place the bet — not where you live.

What Is the Minimum Age to Bet on Sports?

The most common minimum is 21, matching the casino gambling age in most states. But several states went lower. Montana, New Hampshire, Rhode Island, Wyoming, Washington D.C., and Tennessee (per some sources) all permit sports betting at 18.

Washington state is a special case. Wagering is legal only through tribal casinos, and tribal-state compacts set the age at 18. Arizona's tribal compacts, by contrast, require bettors to be 21. Kentucky launched with an 18+ minimum; legislators introduced HB 582 in 2026 to raise it to 21, so check current law before you sign up there.

State-by-State Sports Betting Age Requirements

Why Does the Minimum Age Vary?

It comes down to how each state drafted its sports betting law — or whether tribes set terms via compact rather than legislation. Tribal compacts under the federal Indian Gaming Regulatory Act give tribes meaningful control over age rules at their properties. That's why Washington state and Arizona can land on opposite numbers even though both rely on tribal operators.

States that passed legislation quickly sometimes kept the age consistent with their lottery (18 in several cases). Others mirrored their casino floor rules (21). There's no federal floor — each state decides.

How Geolocation Enforces the Age Requirement

Your eligibility is based on your physical location at the moment you bet — not your home state. Sportsbook apps use geolocation software to verify you're inside a legal state's borders. Cross into a neighboring state and the app may lock you out, regardless of your age or where you opened the account.

This matters for moneyline bettors who travel. Placing an NFL moneyline bet from a hotel in a state where you're underage — even if your home state allows it — violates the terms of that sportsbook's license.

Which Sportsbooks Operate in 18+ States?

The major licensed operators — FanDuel, DraftKings, BetMGM, Fanatics Sportsbook, and Caesars — are live across multiple states and adapt their age verification to local law. Vermont, for example, has exactly three licensed books: DraftKings, FanDuel, and Fanatics Sportsbook. Vermont requires bettors to be 21. Always verify the requirement in the app before completing registration.

For a full rundown of which operators are available where, see the best licensed sportsbooks for moneyline betting. You'll find state-by-state availability along with notes on welcome offers — including BetMGM's up to $1,500 back in bonus bets on a losing first wager.

Bonus bets are non-withdrawable; only winnings from using them can be cashed out. Rollover requirements can run up to 25× deposit plus bonus before withdrawal is permitted. Read the fine print. For more on how promos work, see welcome bonuses for moneyline bettors.

What Happens If You Bet Below the Legal Age Limit?

Sportsbooks are required to verify age during account creation. If an underage account is discovered, the operator can — and typically does — void all wagers and forfeit any balance. No regulatory body will intervene on your behalf. Don't try to shortcut the process.

Sports betting age requirements for moneyline wagering come down to one rule: know your state's law before you deposit. When in doubt, assume 21. If you're in a confirmed 18+ state and want to understand how the odds and payouts work once you're signed up, start with what is a moneyline bet or run the numbers using the moneyline payout formula.
