What the price required

At -126, this selection had to win 55.8% of the time simply to break even — that is what the price itself demanded, before any view about the event.

What the market did afterwards

This selection was taken at -126 and the market closed at -125, a closing line value of -0.2 percentage points. Closing line value measures whether the price beaten was better than the one the market settled on; it is the strongest available leading indicator that a model is pricing something the market had not yet.

How this report was produced
