Sportsbooks vs prediction market · live
Where Kalshi and the books disagree.
Same game, two markets. The sportsbooks' no-vig fair price against Kalshi's order book — after Kalshi's fee — biggest gaps first.
Pricing every book…
Fair odds = the median no-vig price across every book that prices the same market. EV = fair probability × the best price − 1. Soccer moneylines are only priced when a draw price exists. Kalshi EV uses the ask plus Kalshi's taker fee (0.07 × P × (1−P) per contract). Research only · 21+ · Gambling problem? Call 1-800-GAMBLER.
