Maryland’s newest casino continues to outperform its rivals, reporting gaming revenue over $50m in three of the six full months it’s been open for business.

Figures released Wednesday by the Maryland Lottery and Gaming Control Agency show the state’s six casino operators reporting gaming revenue of $130.5m in the month of June, representing a nearly 40% rise over the same month last year.

However, the state’s largest casino, MGM Resorts’ National Harbor, didn’t open until midway through last December, and an apples-to-apples comparison shows the state’s other five operators reporting a year-on-year decline of nearly 14%.

National Harbor continued its place atop the revenue charts, earning $50.1m last month. That’s $400k less than May’s total and $1.1m below March’s record sum, but the property has now topped $50m in three of the past four months, so MGM isn’t likely complaining too loudly.
