The model's call
Chicago Cubs to win

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 | Chicago Cubs | Washington Nationals |
|---|---|---|
| Books consensus fair, de-vigged | 55.4% | 44.6% |
| Best book price incl. vig | 56.5% | 45.5% |
| Kalshi contract price | 54.5% | 45.5% |
| Polymarket contract price | 55.5% | 44.5% |
| Markets average | 55.0% | 45.0% |
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.
