The model's call
Seattle Mariners to win
Model confidence 56.3%
Books consensus 56.3%
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 | Seattle Mariners | Athletics |
|---|---|---|
| Books consensus fair, de-vigged | 56.3% | 43.7% |
| Best book price incl. vig | 58.3% | 45.5% |
| Kalshi contract price | 58.5% | 41.5% |
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.
