Maryland Online Gambling Laws

In-person sports betting and mobile betting are available in Maryland. Maryland House Bill 940 authorizes as many as 100 sports betting licenses — three-fifths of which will go to online and mobile sports betting operators. Seven are currently live following the Nov. 23 mobile launch in Maryland.

State lawmakers beefed the bill up with extra licenses earlier in 2022. This makes the Maryland gambling bill unusual in comparison to other states, with up to 60 mobile betting apps being possible in the state.

Maryland Gov. Larry Hogan signed off on the legislation in May 2022, and now, five Maryland casinos have launched sportsbooks for in-person betting.

Maryland Sports Betting Bill FAQs

Is online gambling safe?

It depends on which site you use. Gambling through state-regulated or monitored websites and mobile gambling apps is the safest way to bet online in Maryland. Legal retail and mobile online gambling operators are regulated or monitored by the Maryland Lottery and Gaming Control Agency. It is not considered safe to share personal or financial information with non-regulated online sportsbooks. 

How can I ensure the safety of my personal information when using online casinos and sports betting sites in Maryland?

The best way to ensure that your information is safe when gambling online is to only bet through online gambling sites that are state-regulated and/or monitored. Gaming vendor certifications and enforcement information are usually available for public viewing on the state regulatory website. Also, make sure that the online gambling website or mobile gambling app you choose is secured by encryption software. A secure website is often indicated by a padlock icon in the URL address bar.

Who operates the online gambling sites in Maryland?

Online gambling sites in Maryland are operated by both legal (state regulated) online gambling operators and illegal operators. Legal sites typically cite their regulatory and licensing agency or agencies on the website. Illegal and offshore sites operate outside the bounds of Maryland law and can leave your information (and money) at risk. 

What happens if I have a dispute with an online gambling site in Maryland?

State regulators with the Maryland Lottery and Gaming Control Agency are responsible for investigating issues involving licensed gambling operators in Maryland. Any compliance issue should be brought to the agency’s attention.

What is the difference between legal and illegal online gambling sites?

Legal online gambling sites are regulated by the state or jurisdiction where a bet is placed. Illegal online gambling does not offer much, if any, security. Bets placed with illegal, unregulated sportsbooks are a good way to lose your bet early and often.
