Overview

Start here for Polymarket perpetual markets

Polymarket Perps are perpetual contracts that track an underlying asset such as an index, commodity, crypto asset, or equity. Perps trade continuously and do not expire, so traders can open, manage, and close leveraged positions without waiting for a market resolution event.

Polymarket Perps is in early access. Access requires a valid [Perps referral link or code](/perps/referral-program).

How Perps Work

A Perps trade starts as an order in the order book. When it fills, it becomes a position whose value changes as the tracked market moves, until the trader closes it or the system closes it because the account can no longer support the risk.

A Perps market has a traded price from the order book and reference prices used by the system. The index price tracks the underlying asset, while the mark price is used for account equity, margin checks, and liquidation risk. Trading a Perps market creates or changes a position. A long position benefits when the tracked asset rises, and a short position benefits when it falls. Orders trade through the order book; fills update the account's position, balance, and history. Perps require collateral to support open positions. That collateral is the account's margin: the buffer that covers losses while a position is open. If account equity falls too far relative to the required margin, the position can be liquidated to close exposure. Funding payments keep the contract price close to the index price. When a market trades above its index price, long positions generally pay short positions. When it trades below its index price, shorts generally pay longs.
