# About Butter

**Butter is a conditionals exchange.**

Conditionals let you trade the forecasted price of an asset conditional on the outcome of an event. Each outcome has its own branch with a branch price reflecting what the market expects the asset to be worth if that outcome occurs. Positions in unrealized branches expire worthless; the realized branch settles to the observed price.
