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 St. Louis CardinalsCincinnati Reds
Books consensus fair, de-vigged 52.2% 47.8%
Best book price incl. vig 52.4% 48.5%
Kalshi contract price 53.0% 47.0%
Polymarket contract price 53.5% 46.5%
Markets average 53.2% 46.8%

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.
