BetMGM has paid a fine of 146-thousand-dollars for violating the state’s Sports Wagering Law. The online sports betting company took wagers on November 16, a week before it was approved to go live in Maryland. According to the company, the bets were taken because there was an error with the app during the pre-launch testing period. BetMGM and six other mobile betting apps officially went live the day before Thanksgiving.
