What Are Perpetual Futures and How They Work

Perpetual futures are a type of futures contract designed to mimic the price of the underlying asset with no expiry date. Unlike traditional futures that settle at a predetermined date, perpetuals keep trading indefinitely, allowing traders to hold positions for as long as they have margin. This structure is especially popular in crypto markets, where traders seek to maintain a position aligned with spot prices without the logistics of rolling over contracts.

Two features set perpetual futures apart from standard contracts: the funding mechanism and the use of an index or mark price to track the asset. The funding rate is a periodic payment between long and short traders, intended to keep the perpetual’s price in line with the underlying index. When the perpetual trades above the index, longs pay shorts; when it trades below, shorts pay longs. Over time, these payments help tether the contract’s price to the real-world price, reducing drift and arbitrage opportunities. You’ll often see funding intervals labeled in hours (for example, every eight hours) and a rate that can swing positive or negative depending on market conditions.

How perpetual futures operate in practice

Margin and leverage: Traders deposit margin to open long or short positions. Leverage magnifies gains and losses, so risk controls and position sizing are crucial.
Price tracking: The contract’s value moves with the underlying asset, but the mark price and the index price keep the contract anchored to reality. This helps prevent dramatic liquidations from short-term price spikes.
Funding payments: At regular intervals, funding is exchanged between long and short traders based on the current funding rate. The direction of the payment depends on how steeply the perpetual is priced relative to the index.
Liquidity without expiry: Since there’s no expiry, traders can adjust their exposure as market conditions evolve, rather than needing to roll over contracts on a schedule.

For practitioners and beginners alike, understanding these mechanics is essential. While perpetual futures offer flexibility and liquidity, they also introduce unique risks. Market swings can cause sudden funding payments, and high leverage can lead to rapid losses if a position moves against you. A thoughtful trading plan with clear risk controls is essential.

Perpetual futures provide a powerful way to speculate or hedge without the constraints of fixed expiries, but the combination of leverage and funding payments means risk management must be a first-order concern.

As you consider practical applications, it’s helpful to connect the concept to everyday experiences. For instance, when you shop for consumer products online, you encounter price-tracking mechanics and orders that execute at favorable moments. A tangible product example is the Neon Card Holder MagSafe Phone Case—available on Shopify—where careful price and availability management mirrors the attention traders pay to underlying price movement. Neon Card Holder MagSafe Phone Case demonstrates how a well-tuned listing can stay aligned with consumer demand over time.
