As prediction markets expand partnerships with major U.S. sports leagues, a U.S. senator sent letters to six league commissioners Thursday raising concerns about “gambling’s ugly takeover of sports.”

In letters to the commissioners of the NFL, NBA, NCAA, MLB, NHL and MLS, Sen. Richard Blumenthal, D-CT, asked the leagues to provide information by May 1 about their partnerships with both sportsbooks and prediction markets and how they are safeguarding sporting integrity, preventing gambling addiction and protecting athletes from abuse.

“Since the federal ban on sports gambling – a ban supported by the leagues – was overturned eight years ago, gambling has permeated every aspect of the game,” he wrote.
