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 | Washington Nationals | Miami Marlins |
|---|---|---|
| Books consensus fair, de-vigged | 36.8% | 63.2% |
| Best book price incl. vig | 37.0% | 64.3% |
| Kalshi contract price | 36.5% | 63.5% |
| Polymarket contract price | 36.5% | 63.5% |
| Markets average | 36.5% | 63.5% |
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.
