Prices are what each side costs right now, in cents per $1 contract, in matchup order (A / B). A venue's two sides usually sum above 100¢ — that's its spread, the equivalent of vig. A positive Sharp Delta is a side selling below fair value despite the spread.

What is Sharp Delta? Sharp Delta = the gap between a venue's ask price (Kalshi, Polymarket) and the de-vigged consensus of 100+ sportsbooks. Positive Sharp Delta means the venue is selling below fair value. Fair value = median de-vigged win probability across every sportsbook in the feed (prediction venues excluded from the consensus). Ask = the implied probability you would pay at that venue right now. Not betting advice; prices move.
