The model's call
Chicago Cubs to win
Model confidence 60.2%
Books consensus 60.2%
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 | Chicago Cubs | Kansas City Royals |
|---|---|---|
| Books consensus fair, de-vigged | 60.2% | 39.8% |
| Best book price incl. vig | 61.1% | 40.5% |
| Kalshi contract price | 61.5% | 38.5% |
| Polymarket contract price | 61.0% | 39.0% |
| Markets average | 61.3% | 38.8% |
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.
