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 | Arizona Diamondbacks | San Francisco Giants |
|---|---|---|
| Books consensus fair, de-vigged | 48.4% | 51.6% |
| Best book price incl. vig | 49.0% | 52.8% |
| Kalshi contract price | 50.0% | 50.0% |
| Polymarket contract price | 51.5% | 48.5% |
| Markets average | 50.8% | 49.2% |
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.
