Perpetual futures have quickly become one of the most popular trading products in crypto, showing how traditional finance and decentralized finance (DeFi) are starting to overlap. Financial tools that have long existed in traditional markets—like futures, options, and other derivatives—are now being reimagined for blockchain, while crypto innovations are beginning to influence traditional finance. This mix of old and new is creating a more open and connected global trading landscape.

Origins in Traditional Finance

Perpetual futures, or "perps," are derivative contracts that allow traders to speculate on the price of an asset without an expiration date. Derivatives are financial instruments whose value is based on (or “derived” from) another underlying asset, such as a cryptocurrency, stock, or commodity. They let traders gain exposure to price movements without actually owning the asset itself. The concept was first proposed by economist Robert Shiller in 1992 to enable derivatives markets for illiquid assets, such as futures on commodities like oil or gold, and index derivatives tied to benchmarks like the S&P 500. However, while perpetual futures have existed in traditional finance, they gained widespread adoption and mainstream recognition with the rise of cryptocurrency markets in the mid-2010s.

Terms to Know

• Derivatives: Financial contracts whose value comes from another asset, such as a cryptocurrency, stock, or commodity. They let traders bet on price movements without owning the asset itself.

• Futures Trading: A type of trading where buyers and sellers agree to exchange an asset at a set price on a future date. It’s often used for speculation or hedging against price changes.

• Spot Trading: Buying or selling an asset for immediate delivery at the current market price. In crypto, this means actually owning the token you purchase.

• Spot Price: The current market price of an asset—the price you’d pay or receive if you bought or sold it right now.

• Leverage: Borrowing funds to increase your trading position size, allowing for bigger potential gains—but also greater risk of losses.

• Perpetual Futures (or “Perps”): A type of futures contract with no expiration date, letting traders hold long or short positions indefinitely while paying or earning funding fees to keep prices aligned with the spot market.

From Crypto's Adoption to Innovation

In traditional finance, futures contracts have fixed expiration dates, requiring traders to roll over positions periodically. Perpetual futures eliminate this need by allowing positions to be held indefinitely, with prices adjusted through a funding rate mechanism to keep them in line with the underlying asset's spot price. This lack of expiration gives investors greater flexibility—they can maintain positions as long as they want, without the hassle or extra costs of rolling contracts—making it easier to trade based purely on price movements rather than time constraints.

Onchain, perpetual futures have become a cornerstone of trading, offering high leverage and 24/7 market access. Platforms like BitMEX, Binance, and Bybit have popularized these instruments, enabling traders to speculate on assets like Bitcoin and Ethereum without owning them. Their rapid growth in crypto reflects several factors: the space attracts high-risk traders seeking bigger rewards, users looking for flexible leveraged positions without expiration, and participants who want to trade around the clock in a highly volatile market. Perpetuals provide the perfect tool to meet all these needs simultaneously.

How Perpetual Futures Work

Unlike traditional futures, perpetual futures do not have an expiration date. They are cash-settled and rely on a funding rate mechanism to ensure the contract price aligns with the spot price of the underlying asset. If the perpetual futures price is higher than the spot price, long position holders pay short position holders, and vice versa. For example, if Bitcoin is trading at $60,000 on the spot market but the perpetual futures price rises to $61,000, traders holding long positions (betting the price will go up) will pay a small fee to those holding short positions (betting the price will go down). This payment helps bring the futures price back in line with the actual market price.

This mechanism allows traders to maintain positions without the need to roll over contracts, providing greater flexibility and continuous exposure to price movements.

Benefits and Risks

One key benefit of perpetual futures is that positions have no expiration, allowing traders to maintain exposure indefinitely without needing to roll over contracts. They also provide access to high leverage, enabling the amplification of potential returns. Since cryptocurrency markets operate 24/7, traders can react to market events at any time, unlike traditional markets with limited trading hours. Additionally, major perpetual futures platforms offer high liquidity, ensuring efficient execution of trades even for large positions.

Despite the benefits, perpetual futures come with significant risks. Cryptocurrency markets are highly volatile, which can lead to substantial losses, particularly when trading with high leverage. Positions can also be liquidated if the market moves against a trader, emphasizing the need for careful risk management. Another factor to consider is the funding fee mechanism, where long or short positions periodically pay each other to keep the contract price aligned with the spot price. These ongoing fees can accumulate over time and impact overall profitability.

Understanding Perpetual Futures in Practice

To better understand how perpetual futures work in practice — and why they can be both powerful and risky — let’s look at two simplified examples. The first shows how a well-timed trade can generate strong returns, while the second illustrates how high leverage and volatility can quickly lead to losses.

Example 1: A Profitable Trade

Suppose a trader believes Ethereum (ETH) will increase in value. ETH is trading at $2,000, and the trader opens a long position on a perpetual futures platform using 5x leverage. This means that for every 1% ETH moves, the trader gains or loses 5% relative to their position size.

A few days later, ETH rises to $2,200 — a 10% increase. Because of the 5x leverage, the trader earns a 50% profit on their initial margin. They close the position and realize the gains, benefiting from the price movement without having to hold any ETH directly.

Example 2: A Losing Trade

Now imagine another trader who believes Bitcoin (BTC) will rise and opens a 20x leveraged long position at $60,000. With such high leverage, even a small price drop can trigger significant losses.

When BTC falls by just 5% to $57,000, the trader’s position is automatically liquidated — meaning their entire margin is lost to prevent further losses. Even though BTC rebounds the following day, the trader is already out of the market.

How They Differ from Traditional Exchange Trading

Traditional exchange trading involves buying and selling the underlying asset, with ownership transferring upon settlement. In contrast, perpetual futures are derivative contracts that allow speculation on price movements without owning the asset. They offer continuous exposure to price changes, with positions adjusted through funding rates rather than expirations.
