U.S. CFTC says it will "respect the opinions of various sports leagues," after the NFL previously called for increased regulation of prediction markets.

Mars Finance news, according to The Block, that Michael Selig, Chairman of the U.S. Commodity Futures Trading Commission, said that when assessing which prediction market contracts are susceptible to manipulation, the agency will “to a very large extent defer to the opinions of the various sports leagues.” Previously, the National Football League (NFL) sent a letter to prediction market platforms such as Kalshi and Polymarket, asking them to stop offering contracts tied to single-game outcomes, drafts, injuries, and other contracts that may be manipulated or effectively determined in advance, believing that such contracts could encourage manipulation. On the legislative front, lawmakers from both parties have introduced a bill to prohibit federally regulated prediction markets from launching sports-related contracts, and multiple states have also challenged the legality of these platforms through legal means. Meanwhile, Major League Baseball in the U.S. has chosen a cooperative approach, partnering with Polymarket and signing an information-sharing agreement.
