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 Miami MarlinsWashington Nationals
Books consensus fair, de-vigged 57.8% 42.2%
Best book price incl. vig 59.2% 42.6%
Kalshi contract price 58.5% 41.5%
Polymarket contract price 57.5% 42.5%
Markets average 58.0% 42.0%

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.
