About this guide: I'm Lawrence, the writer behind supa.is. Between February and May 2026 I've published 150+ articles on supa.is across crypto and brokerage tooling — including 30+ Hyperliquid-specific guides (recent examples: Hyperliquid Order Types Explained, Hyperliquid Trading Liquidations, Hyperliquid Account Value & Unrealized PnL). The most-repeated reader question across that Hyperliquid archive is exactly what perpetual futures actually are and how they differ from spot, which is why I'm publishing this standardized guide instead of answering one-off.
If you trade crypto, you've probably heard "perps." They're the default way to trade derivatives now, but if you're coming from traditional finance or just buying spot, the whole concept can feel backwards.
Unlike traditional futures, perps never expire. There's no delivery date. Instead, they use a mechanism called the *funding rate* to keep the derivative price anchored to the underlying spot price.
In this guide, we'll break down exactly what perpetual futures are, how they differ from spot and expiring futures, how the funding rate works, and how leverage and liquidation fit into the picture.
What Is a Perpetual Future?
A perpetual future is a derivative contract that tracks the price of an underlying asset (like Bitcoin or Ethereum) without an expiration date. You can hold the position open for days, weeks, or even months, as long as you have enough collateral to stay in the trade.
In traditional finance, futures contracts have a settlement date. If you hold a Bitcoin futures contract on an exchange like CME, you must either close it before the expiration date or take physical delivery of the Bitcoin.
Crypto perpetual futures remove this expiration. Because there is no expiration date, there is no natural mechanism forcing the derivative price to converge with the spot price. If the perp price drifts too far from the spot price, arbitrageurs can profit indefinitely. To prevent this, perpetual exchanges use the funding rate.
The Funding Rate: How Perpetuals Stay Anchored
The funding rate is the heartbeat of perpetual futures. It is a periodic payment made between long and short traders to keep the perpetual price aligned with the spot price.
The funding rate is typically calculated every 8 hours (though some exchanges do it more frequently).
Here is how it works:
* Positive Funding Rate: The perpetual price is trading *above* the spot price. Long traders are paying short traders. This incentivizes traders to open short positions, pushing the perp price back down toward the spot price. * Negative Funding Rate: The perpetual price is trading *below* the spot price. Short traders are paying long traders. This incentivizes traders to open long positions, pushing the perp price back up.The funding rate is usually a small percentage (often between 0.01% and 0.1% per interval), but over time, it can add up. If you hold a long position during a bull market with consistently positive funding, you will be paying out a portion of your collateral every 8 hours. If you are short, you are collecting it.
This is a crucial difference from spot trading: holding a perpetual position has a carrying cost (or benefit) that spot trading does not have.
Perpetual Futures vs. Spot vs. Expiring Futures
To truly understand perpetual futures, it helps to compare them to the other two main ways to trade crypto.
| Feature | Spot Trading | Expiring Futures | Perpetual Futures |
|---|---|---|---|
| Expiration Date | None | Yes (e.g., quarterly) | None |
| Leverage | No (1x only) | Yes (up to 100x+) | Yes (up to 100x+) |
| Funding Rate | N/A | N/A | Yes (pays between longs/shorts) |
| Price Tracking | Exact spot price | Spot price at expiry | Anchored to spot via funding |
| Physical Delivery | Yes | Yes (if held to expiry) | No |
How Leverage Works in Perpetual Futures
One of the main reasons traders choose perpetual futures over spot is leverage. Leverage allows you to control a larger position with a smaller amount of capital.

* Spot: You can buy $1,000 worth of Bitcoin (1x leverage). * Perpetual (5x leverage): You can open a $5,000 long position on Bitcoin, using your $1,000 as collateral.If Bitcoin goes up 10%, your $5,000 position gains $500. Since your initial collateral was $1,000, your return on capital is 50%.
However, leverage is a double-edged sword. If Bitcoin drops 10%, your $5,000 position loses $500. Your $1,000 collateral is now down to $500, a 50% loss on your capital.
This brings us to the most dangerous aspect of perpetual futures: liquidation.
Liquidation: The Risk of Leverage
When you use leverage, you are borrowing money from the exchange (or other traders) to increase your position. If the market moves against you, the exchange will not let your collateral drop to zero. Instead, they will force-close your position before that happens. This is called liquidation.
Every perpetual position has a liquidation price. If the market price hits your liquidation price, your position is automatically closed, and you lose most or all of your collateral.
On platforms like Hyperliquid, understanding your account value and unrealized PnL is critical to avoiding liquidation. You can read more about how account value and unrealized PnL are calculated in our Hyperliquid Account Value & Unrealized PnL Explained guide.
To protect against liquidation, traders often use stop-loss orders. A stop-loss automatically closes your position if the price drops to a certain level, preventing a total wipeout. You can also use take-profit orders to lock in gains. Hyperliquid supports a variety of order types to help you manage risk, which we cover in detail in our Hyperliquid Order Types Explained guide.
Why Do Traders Use Perpetual Futures?
Perps aren't just for gamblers blowing up accounts on 100x leverage. They serve several legitimate trading purposes:
1. Shorting the market In spot trading, you can only profit if the price goes up. In perpetual futures, you can open a short position and profit when the price goes down. This is essential for hedging or betting against a bearish market. 2. Hedging spot exposure Suppose you own 1 BTC on the spot market, but you think the price is going to drop in the short term. You don't want to sell your BTC (perhaps due to tax reasons or long-term conviction). You can open a 1x short position on a perpetual futures exchange. If the price drops, your short position makes money, offsetting the loss on your spot BTC. If the price goes up, your long spot BTC gains value, offsetting the loss on your short position. You have effectively neutralized your market exposure. 3. Capital efficiency By using leverage, you can achieve the same dollar exposure with less capital. If you have $10,000 and want $50,000 of Bitcoin exposure, 5x leverage allows you to do that while keeping the remaining $8,000 in stablecoins to earn yield or use for other trades. 4. Arbitrage (Cash-and-Carry) This is a strategy for sophisticated traders. If the funding rate is consistently positive, you can buy Bitcoin on the spot market and simultaneously short it on the perpetual futures market at 1x leverage. You are market-neutral (price movements don't affect you), but you collect the funding rate every 8 hours. This is a popular strategy on platforms like Hyperliquid.Common Pitfalls When Trading Perpetual Futures
If you're new to perps, watch out for these traps:
* Ignoring the funding rate: Holding a leveraged position for a long time can eat into your profits due to funding payments. Always check the current funding rate before opening a long-term position.
* Over-leveraging: 50x or 100x leverage is incredibly dangerous. A small wick in the market can liquidate your position before you have a chance to react. Most professional traders rarely use more than 3x to 5x leverage. * Forgetting about impermanent loss: If you are using a spot position to hedge a perpetual short, you must account for the fact that spot prices and perp prices can diverge slightly, causing small losses on the hedge. * Not using stop-losses: Relying on your gut to close a losing trade is a recipe for disaster. Always set stop-losses to limit your downside.Getting Started with Perpetual Futures on Hyperliquid

What is the difference between a perpetual future and a regular future?
A regular future has an expiration date and will either settle in cash or deliver the physical asset. A perpetual future has no expiration date and uses a funding rate to keep its price anchored to the spot price.Can I lose more than my initial deposit in perpetual futures?
If you use isolated margin, you can only lose the collateral you allocated to that specific position. If you use cross margin, you can lose your entire account balance. Some exchanges offer auto-deleveraging, but generally, you cannot lose more than you put in.How often is the funding rate calculated?
On most exchanges, including Hyperliquid, the funding rate is calculated every 8 hours. However, the exact interval can vary by exchange and sometimes by market.Is perpetual futures trading safe?
Trading perpetual futures involves significant risk due to leverage and liquidation. However, the platforms themselves (like Hyperliquid) are generally secure. The risk comes from the market, not necessarily the exchange. Never trade with money you cannot afford to lose.Can I use perpetual futures to hedge my spot portfolio?
Yes. If you own crypto on the spot market and want to protect against a price drop without selling, you can open a short position on a perpetual futures exchange. This offsets your market exposure.Risk Warning
Risk Warning: Crypto trading involves substantial risk of loss. Never invest more than you can afford to lose. This is not financial advice.
