Maryland

Not only is sports betting legal in Maryland, but the Old Line State has the potential to hold the record for the most online and retail sportsbooks available in one state. As it stands right now, bettors have their choice of 11 online sportsbooks, with plenty more licenses available.

There aren’t many restrictions on sports betting in the Old Line State. Residents are fully allowed to wager on in-state colleges and all professional sports. While there are plenty of sportsbooks to choose from, if a resident prefers to stick with daily fantasy sports, they can find an excellent range of DFS apps in the state, thanks to HB 940, which legalized them in 2021.

Over the years, daily fantasy sports apps made available in Maryland include OwnersBox, Underdog, FanDuel DFS, DraftKings DFS, SuperDraft, and plenty more.

Aside from horse racing being legal, residents also have the option to wager on eSports, which is not available in a lot of states. This means only politics and entertainment events are off-limits to bet on in MD.

Online sports betting in The Old Line State

When legal sports betting was on the 2020 ballot, Maryland voters decided to vote in favor of it. As a result, after the state decided to expand the number of licenses it could offer at one time, Governor Lawrence J. Hogan Jr. signed HB 940 into law in May 2021.

Despite the state's sports betting bill being passed and retail sports betting going live in 2021, online sports betting did not go live in MD until November 23, 2022. Once the bill was passed, the Sports Wagering Application and Review Commission (SWARC) had its hands full when handing out retail licenses, so mobile betting licenses were put on the back burner for an extended period.

It wasn’t until September 2022 that SWARC set a deadline for initial applications for an online operator license in the state. They decided to review and award licenses as they came in to speed up the process of launching mobile betting. By the time early November rolled around, SWARC was able to hand out ten licenses to mobile operators.

These licenses were eventually handed out to some of the most prominent operators in the market, including BetMGM, FanDuel, PointsBet, Barstool Sportsbook (at the time), and more. Once the licenses were handed out, residents did not need to wait long until online sports betting was live.

With the initial licenses handed out in 2022, the state has continually seen movement into and out of the market as sportsbooks like Crab Sports, BetFred, and SuperBook became available to bettors in 2023. Plenty more licenses are available in MD, so residents could have even more variety in the coming years.

Sports betting & gambling legislation in MD

The Maryland Lottery and Gaming Control Agency has established the legal sports betting age in Maryland at 21. This age requirement applies to both online and retail wagers. Remote registration for the state's extensive selection of sports betting apps is available; however, it is crucial that bettors are located within state lines when attempting to place a bet using those apps.

Gambling winnings in Maryland are subject to a tax, but that tax rate will vary between 2% and 5.75% depending on the individual's tax bracket. Those figures are strictly for state tax, as all winnings are also subject to the standard 24% federal tax on winnings.

With local professional sports teams fully intertwined into the sports betting web, the only thing left for the state to discuss is the legality of iGaming. These discussions look to be happening sooner rather than later, with Senator Ron Watson likely to push iGaming legislation during 2024 legislative sessions. Since the lottery is legal in the state, the only two gambling-related products that could be added to the state market are online casinos and online poker.

Betting on Maryland’s competitive sailing regattas

Maryland’s Chesapeake Bay hosts the most prestigious sailing regattas in the country, drawing elite sailors, skilled amateurs, and boating enthusiasts from around the globe. With events like the Annapolis-to-Newport Race and the Governor’s Cup, competitive sailing already carries an air of excitement and tradition, but could it also become a betting market?

Sailing races have all the ingredients for a premier betting market: speed, skill, unpredictable weather, and fierce competition. While traditional sports betting in Maryland is already gaining traction, expanding into sailing events could open a new niche for sailing fanatics and gamblers alike. Bettors could place wagers on factors such as race winners, fastest segments, total completion times, and more, just as they would for other sports that involve racing. 

Of course, like with most novelty markets, regulatory challenges remain. Unlike horse racing or team sports, regatta betting would require oversight from both the state and sailing organizations. The motivation to pass gambling regulations for the sport may be low at the moment, but ff legalized, it could bring new sponsorship opportunities and revenue to Maryland’s historic sailing culture while attracting a fresh wave of fans to the sport.

Could Maryland’s “Blue Crab Derby” become a betting sensation?

Maryland’s Blue Crab Derby is already a quirky and beloved event where spectators cheer on feisty crabs as they shimmy toward the finish line. But could this unique tradition transform into a premier betting attraction? With sports betting gaining popularity, wagering on crab races could create a novelty market similar to horse racing—just with animals that are a bit more dangerous to pet.

Bettors could place wagers on crab speed, crab trifectas, or lane assignments. Casinos or sportsbooks could potentially sponsor races, offering live-streamed races where gamblers could wager from all over the country. Of course, regulations and ethical concerns make this concept a gambling pipe dream, but with the right setup, the Blue Crab Derby could become Maryland’s premier betting spectacle, blending local culture with the thrill of gambling.

In-person sports betting sites and locations

Currently, there are 13 retail sports betting locations in Maryland. However, the state sports betting bill allows 47 retail sportsbook licenses to be handed out. While that number is not close to being reached, residents still have an excellent range of retail options, including casinos, professional stadiums, and racetracks.

Some notable partnerships between operators and retail locations include Fanatics Sportsbook and FedEx Field (home of the Washington Commanders), Caesars Sportsbook and the Horseshoe Baltimore Casino, and Parx with the Green Turtle restaurant.

“Old Bay vs. No Old Bay”: Stadium snack wagering that could spice up Maryland’s betting scene

In Maryland, Old Bay isn’t just a seasoning; it’s practically a cultural identity. So why not bring that spicy state pride into the realm of novelty betting? During Orioles or Ravens home games, concession stands could feature a live fan taste-test showdown between two classic popcorn styles, one with Old Bay and one without. Attendees would cast their votes via a mobile app or in-stadium kiosks after sampling, while bettors could wager in real-time on which flavor will be determined as the winner.

With simple options and results determined by real-time polling, this could be one of the lowest-stakes, high-engagement prop bets available across the country. Adding bonus markets like “fan vote total by inning” only increases the novelty value.

If Maryland’s gaming laws were changed to permit limited wagering linked to in-stadium events, even playful contests like this could generate thousands in seasonal handle. Capturing just 0.01% of Maryland’s multi-billion-dollar betting market through snack-based props could still represent tens of thousands in new wagers and valuable tax revenue. It could also appeal to a group of bettors who may not be as interested in wagering on the game in front of them. 

In short, betting on flavor preference may sound far-fetched, but it directly taps into Maryland’s culinary culture.

Inner Harbor duck boat derbies: Turning tourist rides into gamified attractions

Baltimore’s Inner Harbor has quite a few highly entertaining tourist activities. One of which could become home to one of the quirkiest fantasy leagues in the nation: Duck Boat Derbies. This novelty market would allow players to bet on duck boat participants to see who can go through a given track the fastest. 

Not only could this breathe new life into the city's tourism scene, but it also opens the door for sportsbooks or novelty apps to offer low-stakes bets tied to real-time harbor action. With thousands of visitors every summer, even modest engagement in these races and markets could generate tens of thousands in seasonal handle. It's part sightseeing, part competition, and totally Baltimore.

Sports betting in neighboring states

Maryland is part of a strong group of northeastern states that have legalized sports betting. Residents of MD could venture into any of their surrounding states and still be able to find some form of sports betting no matter which direction they went.

Sports betting revenue impact on Maryland's economy

Maryland is the place to be if you want variety in the online sports betting market. While there are 13 online operators currently active in the state, the state allows up to 60 online licenses to be active. For retail betting, the number of licenses that could be handed out rises to 107.

The Sports Wagering Application and Review Commission is the official group that reviews and issues these licenses when they are applied for. Depending on the license, the fee for operators can range from $50,000 to $2 million. The state has set the tax rate at 15% for both online and retail.

The state has performed well in terms of betting handle, revenue, and tax income with its current number of operators, and Maryland has posted impressive figures since sports betting became legal in late 2021. In the Old Line State's first full year of legalized sports betting, 2022, they achieved just under $1 billion in handle, nearly $150 million in revenue, and over $6 million in tax income.

In 2023, these same figures rose to $4.6 billion (handle), $514 million (revenue), and $46 million (tax income), and a year later, all these annual high marks were already crossed in October 2024. The MD betting market has thus grown by three-digit year-over-year figures. While this pace will for sure settle down in the future, 2025 should be another profitable year for both the state itself and also for legal sportsbook operators.

Betting on local oyster shucking competitions: Precision meets profits

At Maryland’s infamous oyster festivals, such as those in St. Mary’s County or the U.S. Oyster Festival in Leonardtown, shucking isn’t just a skill; it’s a different type of art form. With timed heats, structured judging, and plenty of attendees, these competitions could be primed for a debut into novelty betting markets. Bettors could place wagers on markets that include the fastest shuckers, the number of unbroken oysters, and more.

If local or even well-known licensed sportsbooks introduced prop bets for oyster competitions, it could open the door to new revenue streams during coastal festival seasons. For example, if just 0.1% of Maryland’s $4.5 billion+ annual betting handle came from oyster-related wagers, that would mean $4.5 million in additional bets, in turn, translating to over $675,000 in new tax revenue at the state’s 15% tax rate.
