# Understanding market prices Prices reflect the probability of an event happening, based on current trading activity. For example: In this market **“Will the US FOMC keep the interest rate unchanged?”**, if **‘Yes’** shares are priced at **65c**, that suggests a **65%** chance that the Federal Reserve will **not change** the interest rate. Similarly, if the price of **‘Yes’** shares is **10c**, it indicates only a **10%** probability of no rate change. You can also express your position through **‘No’** shares. For instance, if **‘No’** shares are priced at **80c**, that suggests an **80%** chance that the FOMC **will change** the interest rate. --- # 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.
