How to use the prediction market converter calculator
Prediction markets quote contracts in cents while sportsbooks quote odds. This converter puts both markets on the same scale for faster price comparison.
- 1Enter the current contract price in cents.
- 2Review the equivalent probability and sportsbook odds.
- 3Compare prices only after considering fees and market rules.
Formula and assumptions
Probability = cents / 100. Decimal odds = 1 / probability. American odds are then calculated from that probability.
The conversion treats contract price as probability and does not include prediction market fees, spread, liquidity, or settlement differences.
