Madison Square Garden just locked in Polymarket as the official and exclusive prediction market partner for the New York Rangers—a major signal that prediction markets are crossing into mainstream sports. This move isn't just about adding another integration to a blockchain platform. It's traditional institutions, one of America's most iconic venues, formally betting on decentralized prediction infrastructure. What this really shows: the barrier between Web3 and legacy institutions keeps shrinking. Polymarket doesn't just get venue credibility here—fans get a legit, regulated prediction market right there alongside Rangers games. For the prediction market space, this kind of mainstream partnership is the kind of validation that moves from fringe experiment to actual utility.
