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 | Philadelphia Phillies | Miami Marlins |
|---|---|---|
| Books consensus fair, de-vigged | 44.7% | 55.3% |
| Best book price incl. vig | 46.3% | 56.5% |
| Kalshi contract price | 44.5% | 55.5% |
| Polymarket contract price | 44.5% | 55.5% |
| Markets average | 44.5% | 55.5% |
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.
