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 | San Francisco Giants | Kansas City Royals |
|---|---|---|
| Books consensus fair, de-vigged | 47.4% | 52.6% |
| Best book price incl. vig | 48.8% | 53.1% |

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.
