In the United States, **event contracts** (often called **event-based contracts** or **event contracts USA**) are a type of financial derivative offered by regulated exchanges such as Kalshi or CME. These contracts allow traders to speculate on the outcome of real-world events—such as whether inflation will rise above a certain level, whether a specific election result will occur, or whether a particular sports or weather event will happen.

Each contract typically settles at a fixed amount (e.g., \$1) if the event occurs, and \$0 if it does not, allowing participants to buy or sell based on their expectations. Event contracts are regulated by the **Commodity Futures Trading Commission (CFTC)** in the U.S., which oversees them to ensure compliance with financial laws and limits on gambling-like behavior.

In essence, **event contracts** are a way for individuals or institutions to hedge risk or express opinions about future events within a legal, regulated trading framework.
