It’s been a crazy month for sports betting in America. Caesars Entertainment was brokering deals after being purchased by Eldorado Resorts. The biggest being their acquisition of William Hill. Their CEO, Tom Reeg, recently spoke to CNBC about the legalization of sports betting in this country, and how it’s one of the biggest growth opportunities for gaming in twenty years.

“This is an enormous opportunity. I’d liken it to when states outside of Nevada and New Jersey started to legalize riverboat casinos in the ’90s,” Reeg said. “We think there’s a lot of money to be made here over time, and we’re seeing a lot of interest from non-gaming operators.”

Wall Street has been increasingly interested in sports betting, too. Penn National Gaming’s investment in Barstool Sports, and the possibilities it provides around sports betting, has led to a slew of positive notes from analysts in recent weeks.
