The model's call
Cleveland Guardians to win
Model confidence 62.6%

Identical on purpose: the model applies no adjustment to the books’ de-vigged
consensus until a candidate signal proves itself in shadow audit — none has yet.

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 | San Francisco Giants | Cleveland Guardians |
|---|---|---|
| Books consensus fair, de-vigged | 37.4% | 62.6% |
| Best book price incl. vig | 37.9% | 63.9% |
| Kalshi contract price | 37.9% | 62.1% |
| Polymarket contract price | 38.5% | 61.5% |
| Markets average | 38.2% | 61.8% |
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.
