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.

常见问题

What does it calculate?
Position payout, profit, and ROI for prediction-market contracts; YES+NO arbitrage detection; and Kelly-optimal stake sizing given your estimated edge.
What is the Kelly stake?
The Kelly criterion sizes a bet to maximise long-run growth given your edge and the odds. The calculator computes it so you don't over- or under-bet.

Yes — all math runs in your browser, nothing is sent anywhere.
