How to use

  • 1. Choose the market (to win or to be nominated) and the platform
  • 2. Choose a contender and enter an amount in dollars
  • 3. Choose YES or NO
  • 4. Read the fill price, slippage, fees and payout for that amount

Market data, not advice. Prices are what traders paid on Kalshi and Polymarket, shown per platform or as their average; they are not predictions or recommendations. The calculator is arithmetic on the amount you enter and the order book at that moment.
