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 at the close.
| Venue | Seattle Mariners | Toronto Blue Jays |
|---|---|---|
| Books consensus fair, de-vigged | 48.9% | 51.1% |
| Best book price incl. vig | 48.1% | 50.7% |
| Kalshi contract price | 48.5% | 51.5% |
| Polymarket contract price | 49.5% | 50.5% |
| Markets average | 49.0% | 51.0% |
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.
