FadeTheVig is an independent price-comparison tool. "Crowd" = prediction markets (Kalshi, Polymarket); "House" = US-regulated sportsbooks. We are not a sportsbook or exchange, take no bets, and nothing here is betting, investment, or financial advice. Data may be delayed or wrong.
Sportsbooks shown are US state-regulated books only. Kalshi and Polymarket availability varies by state and is subject to ongoing litigation.
