How the payout works
Every contract settles at $1 if it resolves in your favor and $0 if not. Your cost is the price you pay per contract (in cents) times the number of contracts, plus the trading fee charged up front.
So for 100 contracts at 65¢: stake = $65, fee ≈ $2, total cost ≈ $67. Max payout = $100. Profit if it resolves Yes = $33. Loss if it resolves No = the full $67.
Breakeven win rate — and why it beats the price
Breakeven win rate = total cost ÷ max payout. At 65¢ with fees, that's $67 / $100 = 67% — a couple points above the 65% the price implies. That gap is the fee drag.
The position is profitable long-run only if your honest estimate of the true probability is above the breakeven, not just above the quoted price. Feed your edge into the EV & Kelly calculator to size it.
Selling before settlement
You don't have to hold to resolution. Prediction market prices move with news and game flow, so you can sell your contracts early — for more or less than you paid. This calculator covers the hold-to-settlement case (the $1 / $0 outcome); an early sale settles at whatever the market price is at that moment, minus any taker fee on the exit.
