    What is the Prediction Market Converter?

    Prediction markets like Kalshi and Polymarket quote prices in cents — a Yes contract at 56¢ pays $1 if it wins. That cent price is just an implied probability wearing a different hat. This converter translates contract prices into American and decimal odds so you can compare exchange prices directly against sportsbook lines.

    How to use it

    1. 1.Enter the contract price in cents (1–99).
    2. 2.Read off the equivalent American odds, decimal odds, and implied probability.
    3. 3.Compare against the sportsbook price for the same outcome — exchanges are often the sharpest number available.

    Example

    A 56¢ contract equals -127 in American odds. If a sportsbook offers +110 on the same outcome, the exchange thinks that bet wins far more often than the book is paying for.
