Fanatics has taken its sportsbook live online in Maryland, Massachusetts, Ohio and Tennessee.
The launch comes after six months of beta testing, with the app available for download on iOS and Android devices.
Fanatics Sportsbook offers a range of markets including moneyline bets, spread bets, player props and same-game parlays.
Scot McClintic, chief product officer at Fanatics Betting and Gaming, said the operator is “laser focused on solving pain points facing customers,” adding that the company has had the “strategic patience to build a product for the long-term” that it hopes can “redefine a customer’s expectation of what a sportsbook should be.”
Fanatics will soon have access to more US states after it bought the US arm of PointsBet in a US$225m deal after initial competition from DraftKings.
Fanatics' online launch comes amid FanDuel already being established across the US sports betting scene, but it will be joined later this year in trying to take market share by ESPN Bet, a rebrand of Barstool Sportsbook in a $1.5bn deal between Penn Interactive and ESPN.
