The state-by-state truth
about online sportsbooks.

01What "38+ legal states" actually means

The number you see most often — 38 states plus DC have legal mobile sports betting — is approximately right and almost always wrong about what it implies. Mobile sports betting is legal in 38+ US states as of this writing; the exact list moves as new states pass legislation or, occasionally, as ballot initiatives reverse course. Our sportsbooks hub verifies the current count and the operators live in each state.

But "legal in 38 states" hides three distinctions that matter to a reader signing up:

• Legal vs. live. A state can have passed enabling legislation but not yet issued operating licenses, or issued licenses but no operator has launched yet. North Carolina, Vermont, and Maine each spent a year or more in this state.
• Operator availability inside a legal state. The state legalizing online betting does not mean every operator is licensed there. New York is legal but Bally Bet and Caesars launched well after DraftKings and FanDuel. California is legal for tribal in-person but mobile remains illegal — the 2022 propositions failed at the ballot and no replacement has passed.
• Retail-only vs. mobile. A handful of legal-betting states allow only in-person sportsbooks at licensed casinos, not mobile apps. Mississippi was retail-only for years; the practical experience for a remote bettor is very different from a mobile-legal state.

The single best way to verify your state is to open the sportsbooks hub, look at the live operator list, and check what is available where you live. The general "38+ states" headline is correct as a category statement; it does not predict what is available to you specifically. We maintain state pages for the markets we cover in depth — for example Colorado — and the list expands as we verify per-state operator availability.

02The geo-fencing mechanic

Online sportsbooks use geolocation services — usually GeoComply, the dominant provider — to verify that you are physically located in a legal-betting state every time you place a wager. Not every time you log in. Every time you place a wager. The check pulls your device's GPS, IP, Wi-Fi triangulation, and cell-tower fingerprint, then compares the result against state borders.

What that means in practice:

• If you live in New Jersey and you cross into New York for an afternoon, your NJ-based DraftKings account will let you log in, browse odds, see your balance, and watch a live game — but the moment you try to place a wager from New York, the app will block the bet and surface a "you are not in a legal state for this account" message.
• Conversely, if you have an NJ account and you drive to Las Vegas, you cannot place wagers using your NJ account from Nevada. Nevada is a legal-betting state, but your account is licensed to NJ. Your account does not move with you.
• VPNs do not bypass the check. GeoComply detects VPN use as a discrete signal and the account is flagged. Multiple attempts can close the account permanently.

The geofence is also why border-state living is genuinely tricky. If you live in a household that straddles a state border — common in the NJ/PA, NY/NJ, MA/RI, and KS/MO corridors — the geofence is sensitive to your exact GPS, not your billing address. We have heard reader reports of accounts blocked when wagering from the wrong side of a property line. The fix is usually to physically move and re-locate; the failure mode is a "you are not in a legal state" error that disappears when you walk 30 feet.

03Why your account doesn't move with you

The reason a New Jersey DraftKings account does not work in Nevada is that each state regulates its own sportsbook licenses. DraftKings holds a separate operating license in each state in which it operates. The license includes specific rules — tax rate, advertising rules, responsible-gambling requirements, sometimes even maximum-bet caps — and the operator must comply with the rules of the state in which the bet is being placed.

From the operator's perspective, your DraftKings-NJ account and the DraftKings-NV product are different licensed products that happen to share branding, a credit card on file, and a customer service team. They are not the same account. Funds are not portable between them. The promotions are not portable either: a "$200 in bonus bets" offer running on DraftKings-NJ will not appear in your DraftKings-NV experience, and vice versa.

You can hold accounts in multiple states. Some experienced bettors do — they will open the DraftKings product in every legal state they travel to, ahead of needing it. Each opening is treated as a new sign-up under that state's license, and each becomes eligible for that state's welcome promotion. This is one of the reasons our per-operator review pages document the offer separately from the state — the DraftKings Sportsbook review covers the brand; the state-availability section underneath documents which state's variant is currently strongest.

04DraftKings and FanDuel across states

The big two — DraftKings and FanDuel — run in the largest number of states. Their cross-state inconsistency is also the most visible. Three examples.

The takeaway is that the brand on the app is not the same product across states. Read the operator's per-state page before signing up; read the state-specific promotional terms before accepting any welcome offer. Our FanDuel review and DraftKings review document the brand-level baseline.

05Promo restrictions per state

Several states have layered specific rules on top of the general legal frame, all of which affect what a "bonus" actually looks like in that state.

• New York applies the strictest set of promotional-marketing rules of any current legal state — caps on how a bonus can be advertised, stricter disclosure language, and limits on bonus structure relative to the underlying deposit.
• Massachusetts requires operators to display responsible-gambling disclosure and helpline information prominently in any promotional copy, with regulator-specified language. Welcome promotions that ship in other states sometimes don't appear in MA until the disclosure has been added.
• Ohio has previously fined operators for promotional language that crossed into specific prohibited claims around "risk-free" or "free" bets — operators have moved to "bonus bets" branding partly in response.
• Tennessee applies a state-specific hold-percentage floor; operators have adjusted promotional generosity to keep within the required hold.
• [placeholder: additional per-state promo rules — verify against compliance/data source before publishing]

None of these regulators are wrong to impose the rules. The point for the reader is that the welcome bonus in your state is not the welcome bonus you see in the operator's national advertising. Always check the in-app promotion under the geofenced version of the operator that matches your state.

06How to evaluate a sportsbook before you sign up

Five questions to answer before you create an account:

1. Is mobile sports betting legal in my state? Open the operator's state-availability page and our sportsbooks hub and confirm.
2. Is the specific operator licensed in my state? Legal in your state ≠ all operators are present. Some launched late; some haven't launched at all.
3. What is the in-app welcome promotion at your geofenced location? Not the national version. The version that loads when you open the app from your state.
4. What is the qualifying wager structure? "Bet $5, get $200" sounds simple; the conversion ratio from bonus bets to withdrawable cash is rarely 1:1. Our free-bet calculator handles the math.
5. What are the deposit and withdrawal methods in your state? Some payment processors are unavailable in specific states. Skrill, PayPal, and ACH availability varies by license.

If you live in a state where mobile sports betting is not yet legal — most notably California and (in practice) Florida for non-Seminole-operated betting — the legal alternative is a sweepstakes sportsbook or social product. Operators like Fliff run a sweepstakes-frame sportsbook product that is generally available in more states than the regulated operators are. The expected value math is different from a regulated sportsbook (see why we don't rank by bonus size for the framework), but it can be a legal path in the meantime.

"Legal in 38 states" is a national statistic. Your account is licensed to one state and your wagers are checked against that state every time. The map matters more than the headline.

Where to go from here

Three concrete next steps:

• Open the sportsbooks hub and find the live-operator section for your state.
• If you live in a regulated state, read the per-operator review for the operator you're considering — start with the DraftKings review, FanDuel review, or BetMGM review.
• If you live in a non-mobile-legal state, check the Fliff social sportsbook review as the closest legal alternative.
