Historical Context

The U.S. Supreme Court's 2018 ruling in Murphy v. NCAA allowed states to legalize sports betting, overturning the Professional and Amateur Sports Protection Act of 1992. This shift enabled states like New Jersey to expand gambling, contributing to a $150 billion industry by 2021.
