One side wins, the other doesn't — but you bought both for less than $1, so you keep the spread no matter how the market resolves.

POL NO 47.0¢ $47.00
Total committed $98.00
Guaranteed payout $100.00
Est. fees (~2%/leg) −$1.96
Net profit (after fees) +$0.04

Before you trade

  1. 01

    Prices move.

    Both legs must fill at or better than the shown prices to lock in the quoted ROI. If you hesitate, the spread can close — or invert. Enter both orders quickly.

  2. 02

    Venue fees are in.

    We net out a 2% fee per leg (4% round-trip). If your actual fee schedule is lower, your profit is higher than the number above.

  3. 03

    Settlement timing.

    Funds are locked until resolution. That can be minutes (game-end) to months (political markets). Plan the capital, not just the trade.
