What is Polymarket?
Polymarket is a prediction market for trading yes/no contracts on real-world events. US residents use Polymarket US, run by QCX LLC as a CFTC-regulated designated contract market that trades in US dollars. The international product is crypto-based and runs on a blockchain.
How Polymarket works
On Polymarket US, each market has one instrument, the Yes side, priced from $0.01 to $0.99.
Buying No is the same as selling Yes, so an order to buy No at $0.40 is a sell of Yes at $0.60. Orders match on a central limit order book against other users; the exchange does not take the other side. Contracts settle at $1 if the event happens and $0 if not, and you can sell before then.
Limit orders can be good till cancel, good till date, immediate or cancel, or fill or kill. The exchange runs nearly 24/7 with a weekly maintenance window every Thursday from 6am to 8am ET, starting September 24, 2026. All open orders are canceled before maintenance, and books reopen empty. During the window, API requests return a 503 error.
How to start with Polymarket
- You sign up with a Google or Apple ID, pick a public username and enter your full name, date of birth and residential address.
- Most accounts verify automatically; others need a government ID and a selfie, and manual review can take 3 to 5 business days.

- The international Polymarket app is a separate crypto product.
Polymarket fees and limits
- Under the fee schedule effective September 25, 2026, Polymarket US uses Fee = theta x contracts x p x (1 - p).
- The taker theta is 0.0695, so 100 contracts at $0.50 cost $1.74 in fees; makers get a rebate with theta -0.0125, up to $0.31 per 100 contracts, paid at the trade.
- At $0.10 a taker pays $0.63 per 100 contracts.
- The same schedule notes a Table Tennis taker coefficient of 0.10 from September 30, 2026.
Risks to know before using Polymarket
- Polymarket US is a fiat, CFTC-regulated exchange that operates as a designated contract market and derivatives clearing organization, so your dollars are held in an account there, not in a wallet you control.
- Markets and balances do not carry over from the international Polymarket app.
- Resting orders are wiped at each weekly maintenance, so plan to re-enter limit orders after Thursday mornings.
