A negative effect was expected for the month of January when it came to casino gaming revenues in the state of Maryland due to the newly opened MGM National Harbor being in operation for their first full month. At least two close competitors were expected to be affected but casinos in the state were still able to see overall growth when compared year-over-year. For the state, January produced $126.2 million via the six casinos, which is an increase of 42.8%.

The top earner was the MGM National Harbor, who was able to earn $48.8 million for January. With the revenues of the venue removed, the state actually saw a decrease in year-over-year earnings, with a drop of just over 12%. Maryland Live was down for the second consecutive month with $44 million in earnings for January. This is a 15.6% decrease and around $8 million less than what was earned in 2015.

The Horseshoe Casino Baltimore also saw a decrease when it comes to year-over-year earnings, of around 14.5% with only $20.2 million in earnings. This is disappointing as the venue was able to see a significant increase of more than 9% for the month of December. However, it was expected that both the Horseshoe and Maryland Live would see a decrease in earnings as the MGM National Harbor became operational.

Revenues were up for Hollywood Casino Perryville with $5.8 million earned, a 4.6% gain. The Rocky Gap Casino Resort was up almost 12% with $3.7 million in earnings. Casino at Ocean Downs was down slightly by 1.2% with $3.7 million in earnings.
