What implied probability means
Implied probability is the percentage chance suggested by a set of odds. For example, decimal odds of 2.00 imply a 50% chance. This helps bettors and prediction market users understand what a price really means.
Worked example
The simplest version is with decimal odds. For a price of 2.00:
- Implied Probability = 100 / Decimal Odds
- 2.00 decimal = 50.00%
- This means the odds suggest a 50% chance before any bookmaker margin, exchange commission, or market fees.
Why implied probability matters
Implied probability helps you compare bookmaker prices, estimate how likely an outcome is, and decide whether a market looks overpriced or underpriced. It is especially useful for exchange betting and prediction markets where users often think in percentages.

FAQ
Is implied probability a prediction? No. It is the percentage chance suggested by the odds, not a guarantee that the outcome is fairly priced.
Why can different bookmakers imply different probabilities? Different prices, margins, and market opinions can all produce different implied percentages.
