Result Philadelphia Phillies won model ✗
Identical on purpose: the model applies no adjustment to the de-vigged consensus of the books and Novig, a no-cut exchange, until a candidate signal proves itself in shadow audit — none has yet. Kalshi and Polymarket 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 Philadelphia PhilliesAtlanta Braves
Books consensus fair, de-vigged 45.7% 54.3%
Best book price incl. vig 46.7% 55.6%
Kalshi contract price 45.5% 54.5%
Polymarket contract price 45.5% 54.5%
Markets average 45.5% 54.5%

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.
