New York’s gaming commission has announced that four of the nine sports betting operators in the state can begin offering mobile bets as early as this Saturday, a long-awaited move state officials have estimated could bring the state up to $500 million in new tax revenue.

Back in November, the New York State Gaming Commission awarded licenses to nine different sportsbooks.

“The remaining five conditionally licensed Mobile Sports Wagering Operators continue to work towards satisfying statutory and regulatory requirements necessary to launch and will be approved on a rolling basis when requirements are met,” the state Gaming Commission said in a press release.

The five other sportsbooks licensed in the state, but not available at launch, are Resorts World, PointsBet, WynnBET, Bally Bet and BetMGM.
