The model's call
Boston Red Sox to win
Model confidence 65.2%
Books consensus 65.2%
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 below are a comparison, not an input.

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 | Boston Red Sox |
|---|---|---|
| Books consensus fair, de-vigged | 34.8% | 65.2% |
| Best book price incl. vig | 35.7% | 67.7% |
| Kalshi contract price | 35.5% | 64.5% |
| Polymarket contract price | 36.0% | 64.0% |
| Markets average | 35.7% | 64.3% |
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.
