The Signal Board puts Kalshi odds, Polymarket odds and sportsbook odds on the same outcome side by side, live, and shows where they disagree. Sportsbooks, Kalshi, and Polymarket price the same games differently; GhostLeg Intel surfaces that three-way divergence in real time so you can see when prediction markets and sportsbooks tell different stories about the same outcome.

Kalshi sports betting contracts and Polymarket contracts are read as implied probabilities and set against the sportsbook consensus, game by game. Choose the league with the sport pill, and switch the market segment between moneyline, spread and total. The hub indexes per-sport divergence feeds for NBA, NFL, NHL, MLB, UFC, EPL, NCAAB, and MLS, a whale tracker for large prediction-market and sportsbook moves, and model intelligence covering signal model performance and CLV by score band.

A gap between a book and a prediction market is what people search for as prediction market arbitrage. The board shows the gap as a measurement, in probability points, and does not tell you whether it can be traded or whether it will close. Nothing on this page is a pick. The divergence feed is free, and the same data powers the GhostLeg Data API at ghostleg.ai/data-api.
