The fantasy sports industry is massive, worth roughly $23bn to $37bn as of the 2024-2025 season. Dominated by DraftKings and FanDuel, the duopoly pulled in a combined revenue of $10.5bn in 2024. Yet the design space is stagnant. For years, fantasy sports have followed the same, limited model: short-term predictions with no persistent asset ownership and limited skill expression. Now, a new player is changing the game: http://sport.fun (SDF). Since launching its Pro version in August 2025, the platform has grossed almost $10mn in revenue. SDF is a prediction economy where your edge lies in your ability to accurately predict the best performing athletes relative to other players. Players buy fractional shares of athletes to build a squad that outperforms other players in weekly, real-world data tournaments. You can rebalance and rebuild your squad every match week, or you can set and forget your team for weeks at a time. Accurate predictions drive demand for your athletes’ shares, tradable for Gold and redeemable for USDC. Strong tournament results earn Tournament Points, which unlock player packs and new shares. @footballdotfun was the beginning. SDF is the endgame, aiming to build a prediction economy and social graph around every major sport.(Delphi Digital)
