# What Is Polymarket US?

> Overview of Polymarket US, a Commodity Futures Trading Commission (CFTC)-regulated exchange for trading event contracts

Polymarket US is a **CFTC-regulated exchange** for trading event contracts on real-world outcomes. Each market asks a clear question about something that might happen, and prices reflect how likely traders think the outcome is.

## How Event Contracts Work

Event contracts are Yes/No trades on whether something will happen. Each contract settles at **\$1 if the event happens and \$0 if it does not**.

**Example**: *Will the Rams win Super Bowl 2026?*

If you buy Yes at 12¢ and they win, the contract settles at \$1. If they lose, it settles at \$0. You can trade until the outcome is known.
