It could be, as you can see they have a good advertisement in TV and to afford that kind of advertisement you need to be a rich gambling site or sports book. What really makes the gambling site rich is when they have a lot of bettors from the sports betting industry, sports betting industry is a huge industry where some of the professional capper or the whales made a huge bet during the special season or like for example this NBA playoffs, I am pretty sure the sports book are making a lot of money as some games goes to game 7, the more the game last the better they make money from the equal actions of the different sides.
