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 | Kansas City Royals | Houston Astros |
|---|---|---|
| Books consensus fair, de-vigged | 42.9% | 57.1% |
| Best book price incl. vig | 44.2% | 59.2% |
| Kalshi contract price | 43.0% | 57.0% |
| Polymarket contract price | 43.0% | 57.0% |
| Markets average | 43.0% | 57.0% |
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.
