Sports Edge Model — every game called, every call graded, in public

Pittsburgh Pirates at Cleveland Guardians

The model's call
Pittsburgh Pirates to win
Model confidence 52.2%
Books consensus 52.2%
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 PiratesCleveland Guardians
Books consensus fair, de-vigged 52.2% 47.8%
Best book price incl. vig 54.5% 49.5%
Kalshi contract price 49.5% 50.5%
Polymarket contract price 48.5% 51.5%
Markets average 49.0% 51.0%

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.
