The NFL is taking its fight over prediction markets regulation to the Supreme Court, according to a CNBC post shared on Facebook. The league has been a vocal opponent of expanding event contracts into sports outcomes, arguing that such markets threaten competitive integrity and player privacy. The NFLPA has separately raised concerns about player privacy with legalized sports betting.

A Supreme Court ruling could settle whether sports leagues can block or shape prediction markets on game outcomes, directly affecting how Kalshi, Polymarket, and other platforms structure sports event contracts.
