# Polymarket US

> Overview of Polymarket US, a 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 yes/no 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?*

* You can **buy or sell contracts** based on what you think will happen
* 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
