How Prediction Market Pricing Works

Prediction markets price contracts in cents from $0.01 to $0.99. The price represents the market's implied probability that an event will happen. A YES contract priced at 65¢ means the market thinks there's a 65% chance the event will occur.

If you buy a YES contract at 65¢ and the event happens, you receive $1.00 — a profit of 35¢ per contract. If the event doesn't happen, you lose your 65¢ investment.

Understanding Your Results

  • Total Cost: How much you're investing (buy price × number of contracts)
  • Max Profit: Your profit if your prediction is correct
  • Max Loss: Your loss if your prediction is wrong (equals your total cost)
  • ROI: Return on investment if you're correct
  • Break-even Probability: The minimum probability needed for the trade to be profitable on average
