The model's call
Boston Red Sox 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.

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 Boston Red SoxBaltimore Orioles
Books consensus fair, de-vigged 52.2% 47.8%
Best book price incl. vig 53.5% 48.8%
Kalshi contract price 52.3% 47.7%
Polymarket contract price 51.5% 48.5%
Markets average 51.9% 48.1%

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.
