Legal mobile sportsbooks officially launched in Maine at 9 a.m. Friday when Caesars Sportsbook and DraftKings began accepting wagers. The two operators are the only legal sports betting apps available to bettors in Maine.

Maine residents will eventually be able to place in-person sports wagers at the state’s two retail casinos and at off-track betting facilities, but a timeline for when those facilities will accept wagers has yet to be determined. Retail partnerships for Maine sports betting have also yet to be announced.

DraftKings partnered with the Passamaquoddy Tribe to be one of the state’s two digital platforms, while Caesars Sportsbook announced in May its partnership with three of the four Wabanaki Nation tribes.
