What the implied probability means
Every price is a probability in disguise. The implied probability is the win rate a bet must clear just to break even at that price, before the book's margin. Convert a line to a percentage and you can compare it against your own estimate: if you think the outcome is likelier than the price implies, the bet has value; if not, it does not.
