What is implied probability?

How it works

For negative American odds, divide the absolute value of the odds by that number plus 100. For positive odds, divide 100 by the odds plus 100.

What to remember

Sportsbook prices normally include margin, so raw implied probability is market context rather than a pure forecast. Removing the two-way margin produces a simple no-vig market view.

Betting markets are information, not guarantees. Use them as one input when making your own decisions.
