Legal sports betting in the US may become a $6 billion industry in a five-year time frame should the U.S. Supreme Court rules in favor of New Jersey’s petition.

The Philadelphia Tribune reported that at least 32 states will legalize sports betting right after the SC decides that the federal government cannot prohibit states from offering such gambling, citing an Eilers & Krejcik Gaming, LLC (EKG).

According to the report, legal sports betting in the 32 states will be worth more than US$6 billion.

“We estimate that a properly regulated market could be worth nearly five times that amount, resulting in a financial windfall for sports betting operators, sports leagues and media and state governments alike,” EKG managing director Chris Grove said, according to the report.
