# Buying Yes vs Selling No

> Understand the difference between buying Yes and selling No shares

Each market on Polymarket US asks a question about a future event. Every market has two outcomes: **Yes** and **No**.

* **Yes pays \$1** if the event happens
* **No pays \$1** if the event does not happen

Only one side pays out. The other settles at \$0.

## Buying Yes vs Selling No

Buying Yes and selling No express the **same view**:

* **Buying Yes** means you think the event will happen
* **Selling No** means the same thing — you expect the event to happen

They are two ways of taking the same position. Choose the side you prefer.

<Note>
  Shorting is covered in the Advanced lane. See the [Shorting chapter](/polymarket-learn/advanced/shorting) for details.

## Prices Always Add Up to \$1

Yes and No prices always add up to **\$1**. If Yes trades at **\$0.70**, No trades at **\$0.30**. These prices reflect the market's implied probability of each outcome.
