If you’ve ever watched your buddy hit a parlay in New Jersey or sweated a same-game bet in Pennsylvania, you’ve probably asked yourself: Why can’t I do this in my state? The answer is, you can thanks to the explosive rise of social sportsbooks like Portfolio EV has models for all of these)!
Traditional sportsbooks are still locked out of many U.S. states. But social sportsbooks operate under sweepstakes laws, meaning you don’t have to deposit a dime of real money to play — and yet, you can still walk away with real cash prizes.
Here are the biggest names changing the game.
