FanDuel, founded in 2009 and now part of Flutter Entertainment, brings prediction-style event contracts to its very large U.S. sports audience. It gained the necessary regulatory footing through the acquisition of an introducing broker, mirroring the broader migration of sportsbooks into the CFTC-regulated exchange model.
The pull is a polished, mainstream app and an enormous built-in user base. As an early-stage prediction product, its market breadth is still concentrated in sports and entertainment.
