“There is no question that the growth of the Pennsylvania sports betting market has been slowed by the delayed launch of online apps,” said Jessica Welman, sports betting analyst for PlayPennsylvania.com. “The launch of sports betting apps will give us our first true look at Pennsylvania’s potential as a market, which we believe should rival New Jersey and eventually Nevada as the nation’s largest market.”

Online sports betting is legal in New Jersey and accounts for 80% of all sports betting accounts in the state, according to PlayPennsylvania. However, Pennsylvania has already generated over $125 million in sports bets since it was legalized in the Keystone State in November.

Previously, Pennsylvania sportsbooks only offered in-person betting and gambling sites and apps like DraftKings and FanDuel required users to physically be in New Jersey or another state with mobile betting in order to log in.
