The model's call
St. Louis Cardinals to win
Model confidence 60.1%
Books consensus 60.1%
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 Colorado RockiesSt. Louis Cardinals
Books consensus fair, de-vigged 39.9% 60.1%
Best book price incl. vig 40.0% 61.1%
Kalshi contract price 40.0% 60.0%
Polymarket contract price 41.5% 58.5%
Markets average 40.7% 59.3%

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.
