What is Underdog Fantasy?
Underdog Fantasy is an online daily fantasy sports platform specializing in innovative formats like Best Ball drafts, where users draft teams without ongoing management, and Pick'em contests focused on player prop predictions.
The operator offers season-long, weekly, and daily contests across major sports including the NFL, NBA, MLB, NHL, PGA, and more, with potential payouts up to 1,000x entry fees.
Where is Underdog Fantasy Legal?
Underdog Fantasy is legal in 41 U.S. states, Washington D.C., and all Canadian provinces except Ontario, with full access for Pick'em and Best Ball contests in most locations.
You won't find Underdog Fantasy in Connecticut, Hawaii, Idaho, Iowa, Louisiana, Maine, Montana, Nevada or Washington due to DFS regulations. Age requirements vary—18+ in most states, but 19+ in Alabama and Nebraska, and 21+ in Arizona and Massachusetts—and users must be physically present in eligible areas to play.
Betting Markets at Underdog Fantasy
Underdog Fantasy primarily offers DFS-style markets centered on player props and team outcomes in Pick'em contests but has also recently expanded to sports prediction markets in 16 states, including event contracts on NFL, college football, and MLB spreads, moneylines, and totals, treated as CFTC-regulated trades rather than traditional bets.
Bet Types at Underdog Fantasy
Underdog Fantasy features Pick'em bets, where players select higher or lower on 2-5 player stats, alongside Rivals for head-to-head prop matchups. Best Ball drafts allow automated team building via snake drafts for season-long or daily contests without lineup management, including formats like Battle Royale and Sit N Go tournaments.
Additional types include prediction market contracts for spreads, moneylines, and totals, plus combo entries mixing fantasy picks with event trades, with insurance options on longer parlays for reduced risk.
