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.

Closing moneyline by book

The last price each book posted before first pitch — the prices this call could actually have been bet at. Best on each side is highlighted. In-game odds are deliberately excluded: once the game starts, the price tracks the score, not the matchup.

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 at the close.

Venue Pittsburgh PiratesCincinnati Reds
Books consensus fair, de-vigged 54.0% 46.0%
Best book price incl. vig 54.1% 46.5%
Kalshi contract price 54.5% 45.5%
Polymarket contract price 53.5% 46.5%
Markets average 54.0% 46.0%

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.
