What you will learn here

The ground this section walks over, so you know whether it is the right place to start.

  • How it works

    What you are buying when you buy a share, why prices read as percentages, and what happens at resolution.

  • Is it safe

    Where the money sits, what the real risks are, and which worries are overblown.

  • What it costs

    Trading, deposit and withdrawal costs, and the ones that only show up when you move funds.

  • The vocabulary

    The terms that appear everywhere and are explained nowhere, so the rest of the site reads normally.

Frequently asked questions

Is Polymarket legal where I live?

It depends entirely on your country, and access is blocked in several. The restricted countries guide covers who can use it and how the block works. Check before funding anything.

How much do I need to start?

Less than most people assume. Positions can be a few dollars, and starting small while you learn how resolution and exits work is the sensible way in.

What does a price of 34 cents mean?

The market thinks there is roughly a 34 percent chance of that outcome. If it happens, the share is worth a dollar. If it does not, it is worth nothing.

Can I sell before the event happens?

Yes, and that is the main thing separating this from a bet. You can exit any time the market has liquidity, at whatever the price is then.
