Positive Sharp Delta right now

No venue is currently selling ≥2.5pts below fair value. Markets are tight right now — that's an honest reading, not a broken screener.

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.
