Tucked into the gambling bill that was approved this week by the Florida Legislature is a provision that could lead to the biggest expansion of betting ever in Florida. Not just sportsbooks, but a license transfer clause that could turn small-scale pari-mutuel gambling houses into sprawling casinos.

The agreement between the state and the Seminole Tribe allows existing pari-mutuels to relocate to other, possibly larger, locations. It also allows gambling licenses to be sold or transferred, which means new casinos or gambling venues could open up in places that never had gambling.

But there are hurdles to cross before that happens, from federal agency approval to court challenges to municipal ordinances.
