Reading the result

Decimal odds are converted to implied probability as 1 ÷ decimal odds. Real market prices may include margin, commission, liquidity effects, and delays, so this value is not a model prediction or a guarantee.

FAQ

What is implied probability?

It is the probability implied by an odds price before accounting for market margin and other costs.

Does an implied probability predict the result?

No. It is a conversion of a price, not a claim about what will happen.
