The study was conducted in December 2013, before MGM was awarded its site license, and 'there is so much that has changed,' said Stephen Martino, former director of the Maryland Lottery and Gaming Control Agency. Horseshoe, smaller and a little farther away, is predicted to see smaller declines.Ī study by Colorado-based consultant Jim Oberkirsch predicted Maryland Live could lose 23 percent of its revenue and Horseshoe 14 percent. Analysts forecast that Maryland Live, the state's largest casino, could see some revenue declines once MGM opens.
