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.

Worked example
Size the trade in contracts — one pair (YES + NO) guarantees $1 at settlement. Scale up or jump to ~$100 committed.
contracts
Each contract pair costs 100.0¢ and pays $1.00 at resolve.
| Leg | Price | Stake |
|---|---|---|
| KAL YES | 42.0¢ | $42.00 |
| POL NO | 58.0¢ | $58.00 |
| Total committed | — | $100.00 |
| Guaranteed payout | — | $100.00 |
| Est. fees (~2%/leg) | — | −$2.00 |
| Net profit (after fees) | — | −$2.00 |
Before you trade
-
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.
-
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.
-
Settlement timing.
Funds are locked until resolution. That can be minutes (game-end) to months (political markets). Plan the capital, not just the trade.
