# 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. See [What are conditionals?](https://docs.butter.markets/welcome/what-are-conditionals-1) to learn more, or jump to [Getting started](https://docs.butter.markets/user-guide/getting-started) to begin trading. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
