Maryland Casinos

Maryland has had legal casinos for more than a decade, and there is a chance that the state joins its neighbors with online casinos in the future.

The state authorized casinos via a referendum in 2008 before expanding to table games in 2012. That has led to six casinos cropping up around the state as part of a growing expansion of Maryland gaming that now includes sports betting.

Read on for more about casinos in Maryland and the future of online casinos in the state.

Are online casinos legal in Maryland?

Currently, Maryland does not have a law legalizing online casinos like nearby Pennsylvania, Delaware and New Jersey have.

There could be online casino gambling in the future, though, as the state has already decided to move into online gambling via sports betting.

There has not yet been legislation that would authorize online casinos, but given the revenue that other mid-Atlantic states have realized, it’s likely only a matter of time before Maryland takes a closer look at the industry.

In PA and NJ, online casino revenue has topped $100 million a month, with tens of millions of dollars going to the state on an annual basis.

In most states, online casinos are run through the land-based licensees. That means the six existing Maryland casinos.

Of course, sports betting law has created a much more open and competitive market for that form of gambling, so it’s possible the same happens with online casinos.

Maryland casino law

The state’s voters approved the construction of up to five casinos with slot machines in a 2008 referendum.

Four years later, the state expanded casinos again with a 2012 referendum that authorized a sixth casino and the addition of table games to casino facilities.

The state’s casinos will have sportsbooks, pending a 2021 law being signed and put into effect.
