Maryland Online Sportsbooks

Yes, and the specific authority matters here. This is not a tolerated gray zone: the operators are chartered by the Maryland Lottery and Gaming Control Agency, remit a statutory tax on their proceeds, and remain answerable to state regulators for how they price a line, settle a dispute, and word a promotion. Once you are 21 and physically inside Maryland, you may open an account with any of those licensed books, fund it with real money, and wager.

The path to legality ran through the voters first. Because the Maryland Constitution requires that new forms of commercial gaming be approved at referendum, the General Assembly could not simply pass a betting bill. It had to ask permission. In November 2020 roughly two-thirds of voters said yes to Question 2, and that mandate cleared the way for the enabling legislation that followed. That order of operations — referendum, then statute — is the same route the state used to authorize its casinos, and it explains why Maryland moved a little slower than neighbors who legalized purely through the legislature.

Wondering how Maryland’s approach lines up with the rest of the country? We map out the patchwork of state rules in our explainer on which states have legalized online gambling nationwide, and the full sportsbooks by state directory lets you set the Free State side by side with its neighbors.

Every operator here holds a Maryland license, so the baseline of legality and safety is already met. This ranking reflects day-to-day execution — pricing, market depth, app speed, banking, and rewards — for a Maryland audience.

Two names deserve a footnote. LetsBetMD, a homegrown Maryland brand, has operated as a smaller local option. Crab Sports, another Maryland-branded book that leaned hard into Old Bay marketing, paused its wagering operations in July 2026, so treat it as inactive until it returns. Note also that Maryland has no live Hard Rock Bet sportsbook, so if you see that brand advertised for another state, it does not apply here. For deeper head-to-head breakdowns, our full sportsbook reviews hub compares these operators nationally.

Mobile drives the handle, but the brick-and-mortar books came first and still matter, especially on big event days when fans want the atmosphere of a sportsbook lounge. Maryland’s retail betting is anchored at its casinos and racetracks. MGM National Harbor in Oxon Hill runs a BetMGM book steps from the Washington border. Horseshoe Casino Baltimore hosts a Caesars sportsbook near the stadiums. Live! Casino and Hotel in Hanover pairs with FanDuel and sits in the busy Baltimore-Washington corridor off Interstate 95. Ocean Downs Casino near the beach in Berlin serves the Eastern Shore crowd, and additional counters operate at smaller venues around the state.

The retail footprint has contracted somewhat as the market has matured. The number of physical locations has dipped after a couple of smaller operators closed their doors, leaving roughly 11 retail books in operation as of mid-2026. Retail wagering is taxed at 15% rather than the 20% mobile rate, and the in-person experience appeals to bettors who prefer paper tickets, cash transactions and a bartender in view. Statute authorizes physical books not only at casinos but at racetracks, off-track betting parlors, professional stadiums and other qualifying venues, so the retail map could expand again if new applicants come forward.

Every operator on this page holds a Maryland license, so the baseline of legality and safety is already met. Where they pull apart is day-to-day execution. When we weigh one book against another for a Maryland audience, we look at:

• Pricing and hold. How much juice the book bakes into standard sides, totals and parlays. Lower hold means more of your bankroll survives the long run.
• Market depth. Whether the book covers Terrapins basketball and Navy football as thoroughly as it covers the NFL, and how deep the live menu runs.
• App speed and stability. Bet placement should confirm instantly, especially for in-game wagers where a two-second lag can cost you the line.
• Banking. The range of deposit and withdrawal methods, and how fast a cashout actually hits your account.
• Bonus fairness. Not the headline dollar figure, but the playthrough terms, minimum odds and expiration windows attached to it.
• Rewards. Whether steady betting earns anything meaningful, and whether those rewards are easy to understand.
• Customer support. Live chat responsiveness and how the book handles disputed settlements.

No single book wins every category, which is why serious Maryland bettors keep two or three apps and shop lines between them.

Pair the book with the way you really wager. A fan who wagers only on Ravens Sundays wants a clean interface and a good welcome offer, so Bally Bet, Fanatics or FanDuel fit. A live-betting addict who watches Champions League and ATP tennis should start with bet365. A bettor chasing casino comps and hotel stays gets more from Caesars or BetMGM because of their loyalty currencies. A value hunter who resents hidden rollover terms belongs at BetRivers. And anyone who wants the widest possible menu of leagues and markets will lean on DraftKings.

The other honest answer is to use more than one. Because Maryland allows every licensed book to set its own lines, the same Orioles run line might be minus-115 at one app and minus-105 at another. Registering at two or three books lets you take the better number every time, and the welcome offers stack.

1. Confirm you qualify. You must be at least 21 and standing inside Maryland when you place a wager. Residency is not required, so visitors from out of state can bet too.
2. Pick an app and download it. Grab the operator’s app from iOS and Android storefronts, or sign up through its mobile site. Avoid links from unofficial sources.
3. Create your account. Because Maryland licensing rules force each book to confirm your identity and your age before it takes a dollar, registration asks for your legal name, your date of birth, your residential address, and your SSN’s last four digits. None of this is a credit inquiry; it is purely an age-and-identity check.
4. Claim the welcome offer. Read the terms first. Note the minimum deposit, the minimum odds a qualifying bet must meet, and any playthrough requirement before you opt in.
5. Fund the account. Debit cards and direct online-banking transfers are the quickest routes, with PayPal, a branded prepaid card, or a cash drop at the casino cage all on the table too. The money almost always lands instantly.
6. Enable location services. The app runs a geolocation check every time you bet. Grant the permission or install the required plug-in on desktop, or your wagers will be blocked.
7. Place your first bet. Keep the opening stakes modest, get a feel for the layout, and set deposit or time limits from the responsible gambling menu before the action heats up.

Maryland regulators keep an unusually close watch on promotions. Operators must submit the terms of any promotion for approval, disclose eligibility, wagering requirements and withdrawal restrictions clearly, and after the first year they face a cap that limits promotional play to a share of the prior year’s proceeds. In practice that means the offers you see in Maryland are somewhat more restrained than in the Wild West early days of other markets, and the fine print is more likely to be enforceable.

The common structures are a bonus-bet match on your first wager, a deposit match spread over time, or a no-sweat first bet that refunds a losing opening wager as bonus credit. The advertised dollar figure counts for far less than the conditions attached. In the Free State a $200 offer with one-times playthrough at even-money minimum odds is worth more than a $1,000 offer buried under heavy rollover. Always check whether the reward arrives as cash or as bonus bets, since bonus bets return only the profit, not the stake.

Our guide to sportsbook bonuses breaks down how to value each structure before you commit a dollar.

Cashiering on a Maryland app is quick and the roster of options is broad. You can move money in by linking a bank account for an ACH transfer, tapping a debit card, routing through PayPal or a comparable e-wallet, loading a branded play card, dropping cash via PayNearMe at a participating retail counter, or handing bills to a teller at a casino cage. Maryland is one of the states that still lets online books accept credit cards, but treat that as a maybe rather than a given: plenty of card issuers block gambling charges, and legislators have floated ending the practice altogether.

Withdrawals typically return to the same method used to deposit. E-wallet cashouts are the fastest, often clearing within hours, while bank transfers take one to three business days and a physical check can take longer. The first withdrawal at any book triggers identity verification if you have not completed it already, so upload your documents early to avoid a delay when you want your money. All of this moves real cash — if that is new territory, our primer on how regulated real money betting works is the place to start.

One practical tip: keep location services on and your app updated, because the most common reason a Maryland bet gets rejected is an out-of-date geolocation module, not an actual problem with your account.

In-play betting has become the centerpiece of the Maryland product. Instead of committing before the opening whistle, in-play betting lets you wager while the action plays out — the next drive, the current at-bat, whether the Ravens convert a third down. Prices move moment to moment, which rewards fans who watch closely and can read momentum before the book adjusts.

bet365 is the clear leader here thanks to its European in-play heritage and live streaming on select soccer and tennis events. FanDuel and DraftKings are close behind for the major American leagues, and most books now offer live same-game parlays that let you combine in-progress markets. The tradeoff is speed: live lines carry more hold than pregame numbers, so treat in-game betting as entertainment rather than a value play, and never chase a bad pregame position with a rushed live wager.

The legal architecture rests on two pillars. The first is the 2020 constitutional referendum, Question 2, which gave the legislature the authority to act. The second is House Bill 940 of the 2021 session, the statute that actually built the system. HB 940 authorized a large and deliberately diverse pool of licenses — up to 60 mobile licenses and dozens of retail licenses — with an explicit goal of broadening ownership among small, minority-owned and women-owned businesses. That equity mandate is a defining feature of the Maryland framework and one reason the state took extra months to vet applicants.

The law splits regulatory duties. The Maryland Lottery and Gaming Control Agency handles day-to-day oversight, promulgates operational regulations, and reports revenue monthly. A separate body, the Sports Wagering Application Review Commission, evaluates and awards the licenses themselves, applying the diversity and market-study requirements written into the statute. You can verify the current regulations directly with the regulator at the Maryland Lottery and Gaming Control Agency.

Maryland allows wagering on professional and college sports, the Olympics and esports, but it draws firm lines around college athletes. The biggest restriction is a ban on individual player proposition bets involving college athletes. You can bet a Terrapins game spread, total or moneyline, and you can bet season-long awards such as the Heisman Trophy, but you cannot wager on how many yards a specific college player gains or how many rebounds he grabs in a single game. Regulators adopted the rule to protect young athletes from harassment, matching a wave of similar bans across other states, and the 2026 legislation reinforced it.

Other guardrails apply market-wide. Books cannot offer wagers on events where the outcome is already known, on injuries, on officiating decisions, or on high school and youth competitions. Operators must submit their catalog of approved bet types to regulators, so a market that would be legal in one framework may simply not be offered in Maryland if the agency has not cleared it.

Who Is Barred From Betting in Maryland

Beyond the age floor of 21, Maryland bars certain people from wagering to keep competition honest. That list includes:

• Coaches, players, officials, league employees, and their close associates betting on their own sport
• Sports governance and league officials with access to nonpublic information
• Employees of the licensed sportsbooks and their vendors
• Members and staff of the regulatory bodies themselves
• Anyone who has signed onto Maryland’s voluntary exclusion list

Attempting to bet through a proxy or with someone else’s account to evade these rules is a serious violation that can void wagers and trigger penalties.

False rejections almost always trace back to a technical hiccup rather than a real location problem. Turning off a VPN, enabling precise location, updating the app, and toggling location services off and on resolve the vast majority of failed checks. A phone set to a low-accuracy location mode is the most common culprit near the state border.

Maryland taxes operators and bettors on two separate tracks. On the operator side, the state originally set a 15% levy on gross gaming revenue across the board. When a large budget shortfall opened up, Governor Wes Moore pitched doubling the mobile rate to 30% inside his 2025 fiscal package. The General Assembly balked at that figure, and the number that made it into the Budget Reconciliation and Financing Act of 2025 (House Bill 352) was 20% on online proceeds, a five-point bump, with in-person books left at 15%. The change took effect for wagering starting July 1, 2025.

The early returns were sizeable: the higher rate produced roughly $146 million in state revenue over its first year, about $36.2 million more than the old 15% rate would have delivered. Where that money lands is spelled out in statute, and it is overwhelmingly a school-funding story. Ninety-five percent of every sports-wagering tax dollar is earmarked for the Blueprint for Maryland’s Future Fund, the multi-year overhaul of public pre-K-through-12 education, and the remaining 5% flows to the general fund. In mechanical terms, a mobile book now sends 15 percentage points of its 20% rate to the Blueprint and the other 5 to the general fund, while a retail book directs its full 15% to the Blueprint.

On the bettor side, winnings are taxable income under both the federal code and Maryland’s income tax, which runs on a graduated scale topping out above 5% before county piggyback rates are added. A sportsbook will issue a federal form for qualifying wins and may withhold up front on the largest ones, but reporting the income is your responsibility whether or not any paperwork arrives, and gambling losses are deductible only if you itemize. Treat this as general orientation rather than tax advice; anyone sitting on meaningful winnings should walk their situation through a qualified Maryland tax professional.

Maryland has matured into a top-tier revenue producer. In fiscal 2026, the state’s sportsbooks accepted $6.91 billion in wagers, an 11.1% increase over the $6.22 billion handled the prior fiscal year. That volume translated into $132.3 million in state contributions, a jump of nearly 49% year over year, propelled in part by the higher tax rate that took effect during the period.

The market set a single-month record in November 2025 with $95.4 million in gross gaming revenue and $19 million in taxes, driven by football season and a favorable run of results for the books. Monthly handle throughout 2025 ranged from roughly $404 million in the quiet summer stretch to nearly $619 million during football season, and Maryland has repeatedly appeared inside the national top 10 for monthly handle.

Several forces are pushing the numbers higher. The proximity of Washington means a large share of a densely populated, high-income metro area sits inside Maryland lines and inside the geofence. The Ravens and Orioles keep the calendar full of marquee dates, and the Commanders playing home games in Landover adds a third heavily bet NFL draw. The tax increase, meanwhile, means each dollar wagered now returns more to the state than it did at launch. The main headwind is competition from the tax hike itself, since operators facing a higher rate tend to trim promotional generosity, but so far handle has kept climbing regardless. Maryland looks less like an emerging market and more like an established one settling into steady, football-weighted seasonality.

Maryland has become one of the sharpest testing grounds in the country for whether sports event contracts are legal wagers or federally regulated financial instruments. Event-contract platforms led by Kalshi, along with names like Polymarket, let users buy and sell yes-or-no positions on who wins a game, and Kalshi’s core defense is that its markets sit under the exclusive jurisdiction of the federal Commodity Futures Trading Commission, placing them beyond the reach of the Maryland Lottery and Gaming Control Agency. Maryland disagrees, and the dispute has an unusually detailed local paper trail. In April 2025 the agency issued Kalshi a cease-and-desist demand ordering it to stop offering sports-linked contracts to anyone inside the state. Kalshi answered by suing in the federal court based in Maryland and asking for a preliminary injunction to freeze the state’s order.

On August 1, 2025, Judge Adam Abelson denied that injunction, refusing to shield Kalshi from Maryland’s licensing demand, and Kalshi appealed to the U.S. Court of Appeals for the Fourth Circuit on August 5. That appeal is the live action. A three-judge Fourth Circuit panel heard oral argument on May 7, 2026, and the judges pressed Kalshi hard, sounding skeptical that a sports contract that pays out on the Ravens or Orioles is meaningfully different from a bet the state is entitled to regulate. The stakes reach past Maryland: a separate Third Circuit ruling went the other way in a New Jersey matter, and if the Fourth Circuit sides with Maryland it would open a circuit split of the kind that tends to pull a case toward the U.S. Supreme Court.

The practical picture as of late July 2026 is unsettled by design. The panel has not yet issued its decision, the platforms remain reachable by Maryland users in the meantime, and none of them carries a Maryland gaming license or the consumer protections that come with one. A resident who trades a sports contract on Kalshi today is stepping into contested legal ground rather than a settled, regulated market, and the outcome of the Fourth Circuit ruling could change what is available overnight. Our overview of prediction markets follows how the same fight is unfolding in other states.

Maryland’s professional landscape has a Baltimore core and a heavy Washington overlap, and understanding that geography helps explain the betting action.

The short version: Baltimore supplies the teams that literally play in Maryland, while Washington supplies several franchises that Maryland fans have adopted as their own. That dual loyalty is a defining trait of the market and a reason its NBA and NHL handle runs higher than a state without pro teams in those leagues would suggest.

Maryland’s college scene is deep, though remember that individual player props on these athletes are off the table. The Maryland Terrapins compete in the Big Ten, giving bettors a steady diet of high-profile football and basketball matchups against national powers — Terps basketball in particular has a passionate following and a history of March runs. The Navy Midshipmen field one of the most distinctive football programs in the country, and their triple-option offense makes for tricky point-total handicapping. Towson University’s Tigers compete in the Coastal Athletic Association and draw regional interest, especially in basketball.

The state also has genuine lacrosse royalty. Johns Hopkins, Maryland and Loyola Maryland are perennial national contenders in a sport that carries outsized cultural weight in the state, and while betting menus for lacrosse are thin, the championship interest is real. Add UMBC, famous for the first 16-over-1 upset in NCAA men’s basketball tournament history, plus Morgan State and Coppin State, and Maryland offers plenty of collegiate action beyond the flagship programs.

Two events stand above the rest because they actually take place on Maryland soil.

The Preakness Stakes, the second jewel of horse racing’s Triple Crown, runs every May at Pimlico Race Course in Baltimore. It is the single biggest wagering day of the year in the state, drawing enormous pari-mutuel and advance-deposit handle. Pimlico is undergoing a major redevelopment, but the Preakness remains a Maryland institution and the centerpiece of the state’s racing calendar. For online horse wagering options, browse our rundown of horse betting.

The Army-Navy Game, college football’s most storied rivalry, has been staged several times at M&T Bank Stadium in Baltimore, and with the Naval Academy in Annapolis the matchup carries special weight in Maryland. It reliably generates a spike in December betting whenever it lands in the state. Beyond those two, Ravens playoff runs and Orioles postseason appearances produce the sharpest in-state handle surges, and the annual heavyweight schedule of Big Ten football keeps the Terrapins in the mix.

Daily fantasy contests operate legally alongside sports betting in Maryland, and major operators including the pick-em and salary-cap platforms serve state residents. DFS predates the sportsbook era in Maryland and gives fans who prefer building lineups to betting sides another regulated outlet. Our daily fantasy sports section covers how these contests work and how they differ from traditional wagering. Note that the same college-athlete sensitivities that shaped the prop-bet ban have also drawn regulatory attention to player-prop-style DFS products.

• The Maryland Center of Excellence on Problem Gambling is the hub of the whole system. Based at the University of Maryland School of Medicine, it trains clinicians, runs public-awareness campaigns, and connects residents to counseling and peer support. Its most important feature for bettors: Maryland residents qualify for no-cost problem-gambling treatment, and the Center can refer you straight to a counselor or to a peer support specialist who has lived through recovery.
• Maryland’s 24-hour Helpline: Call or text 1-800-GAMBLER (the text line is 1-800-426-2537). It is free, confidential, staffed at all hours, and administered through the Center of Excellence.
• The Voluntary Exclusion Program (VEP): Run by the Maryland Lottery and Gaming Control Agency, this is the state’s official self-ban. Enrolling bars you from Maryland sportsbook accounts and from the casinos — including check-cashing and credit privileges inside them — for a fixed term or for the rest of your life, and it is enforced across licensees, not one book at a time.
• The National Council on Problem Gambling helpline: 1-800-522-4700, a 24-hour confidential support line, backs up the state line from anywhere in the country.
• Peer and family support: Gamblers Anonymous and Gam-Anon hold in-person meetings across Maryland for bettors and the people around them.

Every licensed app also builds in controls for capping deposits, capping wagers, capping session time and taking a cooling-off break. Use them before you need them. Setting a limit while you are calm is far easier than trying to rein in the action after a losing streak. Bettors must also meet the state’s legal gambling age of 21, a bar that varies elsewhere by state.

Wagering on games is just one slice of Maryland’s regulated gaming picture. The same casinos that host the retail sportsbooks — MGM National Harbor, Live! Casino, Horseshoe Baltimore and others — anchor a broader industry, and you can compare the full slate of legal options on our Maryland online casinos page. For a sense of how Maryland stacks up against its neighbors, the surrounding states each took their own path: read about the fast-moving market in Virginia, the deep and mature scene in Pennsylvania, and the early-adopting book-friendly rules in West Virginia. You can also explore every regulated jurisdiction through our all states hub.

Maryland’s story is a case study in doing it methodically: ask the voters, build in equity requirements, license a broad and diverse field, then tighten the rules as the market grows. The result four years in is a $6.9 billion market that funds schools, protects college athletes from prop-bet harassment, and gives Ravens and Orioles fans a well-regulated way to have a stake in the games they already love. Bet within your means, shop your lines, and use the tools the state provides to keep it fun.
