How to read: Prediction market prices represent the cost in cents to buy one share. A price of 65¢ means the market implies a 65% probability. If the event occurs, the share pays out $1.00 (100¢). Enter a price above or any odds format to convert instantly.
Prediction markets like Polymarket and Kalshi use a simple pricing system where the price directly represents the implied probability of an event occurring. A price of 65 cents means the market believes there's a 65% chance the event will happen. This calculator converts these prices to traditional betting odds formats used by sportsbooks.
Unlike traditional sportsbooks like FanDuel, DraftKings, and BetMGM, prediction markets have minimal fees built into their prices. Sportsbooks add "vig" or "juice" to their odds (typically 4-10%), which reduces your expected returns. Prediction markets usually charge small trading fees (0.5-2%), making them more efficient for bettors who understand probability.
A prediction market price of 65 converts to approximately -186 American odds, 1.54 decimal odds, and 13/20 fractional odds. This means you'd need to bet $186 to win $100 (plus your stake back) at a traditional sportsbook offering equivalent odds. By comparing across platforms, you can identify which one offers the best value.
