***Murphy v. National Collegiate Athletic Association*** (2018) is the U.S. Supreme Court decision holding that the federal prohibition on state authorization of sports gambling violated the Constitution's anti-commandeering principle.
## Significance
The ruling did not itself legalize sports betting everywhere; it returned the choice to states. It is the legal hinge in the article's account of nationwide sports-wagering expansion and the conversion of athletic uncertainty into regulated handle, tax revenue, and market data.
