What is a prediction market calculator?
Prediction-market contracts pay out $1 if an event happens and $0 if it doesn't, so a price is a probability. This calculator does the math that matters: the payout and ROI on a YES or NO position, the arbitrage when YES + NO prices don't add to 100%, and the Kelly-criterion stake size for an edge you believe in. It's pure, browser-side math; describe it and Cryptohopper.AI builds it.
Common features
- Payout and ROI for YES/NO at a given price
- YES + NO arbitrage detector
- Kelly-criterion stake sizing from your edge
- Implied probability from price
- Instant recompute as you type
- 100% browser-side, no key
Real-world examples
ROI on YES
Buy YES at 38¢ — see the payout and return if it resolves true.
Arb check
Spot when YES + NO sum below $1 for a locked-in edge.
Kelly stake
Size a bet by the Kelly criterion given your estimated probability.
