Prediction markets vs the books

Every venue sells the same thing — a dollar if that side wins — at a different price. Implied cost per venue below; amber = the cheapest way to buy that side right now.

Venue	Pittsburgh Pirates	Cleveland Guardians
Books consensus fair, de-vigged	52.1%	47.9%
Best book price incl. vig	53.7%	50.0%
Polymarket contract price	50.5%	49.5%

Contract prices exclude exchange trading fees (Kalshi ~1–2¢ midrange), which narrow small gaps. A venue meaningfully below the books consensus is either a bargain or an early opinion — the graded record decides which.
