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 at the close.
| Venue | Washington Nationals | Colorado Rockies |
|---|---|---|
| Books consensus fair, de-vigged | 57.1% | 42.9% |
| Kalshi contract price | 57.5% | 43.5% |
| Polymarket contract price | 57.5% | 42.5% |
| Markets average | 57.5% | 43.0% |
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.
