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 | St. Louis Cardinals | Pittsburgh Pirates |
|---|---|---|
| Books consensus fair, de-vigged | 42.5% | 57.5% |
| Best book price incl. vig | 43.9% | 59.2% |
| Kalshi contract price | 41.7% | 58.3% |
| Polymarket contract price | 41.5% | 58.5% |
| Markets average | 41.6% | 58.4% |
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.
