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 Arizona DiamondbacksPittsburgh Pirates
Books consensus fair, de-vigged 44.7% 55.3%
Best book price incl. vig 46.5% 57.3%
Kalshi contract price 45.5% 53.5%
Polymarket contract price 46.5% 53.5%
Markets average 46.0% 53.5%

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.
