Kalshi and Polymarket MLB Odds vs the Books

Kalshi MLB contracts, Polymarket MLB contracts and sportsbook lines on every game of a daily slate. Baseball plays most days of its season, so the board turns over daily: each game's Kalshi odds, Polymarket price and sportsbook consensus are read as implied probabilities and the gap between them is shown per side.

The market segment switches between moneyline, spread and total; in baseball the spread is the run line and the total is the run total. With a slate this size the closing line value (CLV) analytics by signal score band are the page's summary view, the same CLV view every hub carries, read here over a season of daily games.

A daily slate means many games and many gaps on one page. Each gap is a measurement in probability points, not a call on which venue is right and not prediction market arbitrage; the board shows the disagreement and leaves the decision to you. Nothing on this page is a pick. The same intelligence is exposed via the GhostLeg Data API at ghostleg.ai/data-api.
