A price of 35¢ means the market sees roughly a 35% chance. That's called the implied probability.

Quick example

You buy 10 YES at 35¢ = $3.50. If YES wins, you get $10. If it loses, you get $0.

Don't forget

  • Prices change as news arrives.
  • Fees and the bid/ask spread move your real break-even a little.
  • A price is an estimate, not a promise.
