The model's call
St. Louis Cardinals to win

consensus until a candidate signal proves itself in shadow audit — none has yet.

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 | St. Louis Cardinals | Cincinnati Reds |
|---|---|---|
| Books consensus fair, de-vigged | 51.2% | 48.8% |
| Best book price incl. vig | 52.4% | 49.8% |
| Kalshi contract price | 51.5% | 48.5% |
| Polymarket contract price | 50.5% | 49.5% |
| Markets average | 51.0% | 49.0% |
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.
