The U.S. Supreme Court on Monday struck down the 1992 federal law that bans most states from licensing sports betting, opening the door to legalized sports gambling nationwide.

The decision could transform sports and sports gambling from coast to coast. It is currently a mostly illegal activity that, according to the American Gaming Association, “has grown to a $150 billion-a-year industry.”

Responding to the court's ruling Monday, the association issued this statement: “Today's decision is a victory for the millions of Americans who seek to bet on sports in a safe and regulated manner. … Through smart, efficient regulation this new market will protect consumers, preserve the integrity of the games we love, empower law enforcement to fight illegal gambling, and generate new revenue for states, sporting bodies, broadcasters and many others.”
