BetMGM is a product of the Roar Digital joint venture between MGM Resorts and GVC Holdings.
MGM Resorts also announced it is partnering with The Greenbrier, a luxury resort in White Sulphur Springs, West Virginia.
MGM Resorts President of Interactive Gaming Scott Butera said: “We are pleased to be operating in West Virginia and partnering with The Greenbrier, a historic grand hotel and one of the most storied landmarks in the United States.”
DraftKings and FanDuel have so far dominated the online sports wagering market in West Virginia.
The FanDuel sportsbook at The Greenbrier took in $370,000 in online sports betting revenue from 29 Dec - 11 Jan.
West Virginia legalized sports betting in December 2018 and took in $226m of handle in 2019.
Sports wagering revenue topped $19m in its inaugural year in the Mountain State.
Roar Digital CEO Adam Greenblatt said: “"We know the passion for sports in West Virginia, which is why we're launching BetMGM with the very best features and promotions already up and running. West Virginians will notice the care we've put into making this a mobile betting experience for die-hard sports fans and novices alike.”
The launch comes days before the Super Bowl and well in time for March Madness.
