Perpetual Futures vs. Spot Trading: What’s the Difference?

Traders hoping to speculate on the future price of assets face a choice when deciding how they want to get exposure.

For example, someone looking to profit when Bitcoin rises can do so in multiple ways, including buying spot Bitcoin or opening a long perpetual futures (“perps”) trade.

Both will provide the opportunity to profit when the price goes up. Yet, spot trading and perpetual futures trading are fundamentally different.

While neither trading tool is inherently better, they serve different purposes depending on a trader’s goals.

Understanding the differences can help traders choose which tool is right for their trading strategy.

Quick Recap: What Is Spot Trading?

When a trader buys Bitcoin directly from an exchange, they are buying it at its current market price and taking ownership of the asset. This is considered spot trading.

Suppose Bitcoin is trading at $100,000 and a trader buys 1 BTC on an exchange. They now own 1 BTC and will gain or lose as BTC rises or falls. Either way, they own 1 BTC.

One of the biggest advantages of spot trading is that there is no liquidation risk. Even if Bitcoin experiences a sharp drawdown, the trader maintains their ownership.

In the case of an extreme drawdown with perps, a long position could be liquidated, eliminating exposure to the asset.

Spot trading also allows traders to:

• Transfer assets elsewhere, like to a non-custodial wallet if trading crypto
• Hold it indefinitely
• Stake it or lend it to earn rewards or yield (where supported)

Quick Recap: What Are Perpetual Futures?

Perpetual futures are derivative contracts that let traders speculate on the price of an asset without owning it.

Perps also allow for leverage trading. Instead of needing $100,000 to get $100,000 of BTC exposure, a trader can deposit collateral (initial margin) and open a levered long or short position.

This allows traders to use smaller capital amounts to generate relatively large exposures.

A trader that wants $100,000 exposure could deposit $20,000 and use 5x leverage.

If Bitcoin rises 10%, the position gains around 50% relative to the collateral (10% times 5x leverage), representing a gain of around $10,000, less fees and funding costs.

Leverage works in both directions though. If Bitcoin falls, losses are amplified equally. If losses become too steep, a clearing member may liquidate the position.

Because perps never expire, they remain connected to the spot market via the funding rate, a periodic payment that is exchanged between long and short traders.

This allows traders to keep positions open indefinitely so long as they maintain sufficient margin requirements.

Six Key Differences Between Spot Trading and Perpetual Futures

There are multiple differences between spot trading and perpetual futures.

1. Ownership: Do you actually own the asset?

A key difference between spot trading and perpetual futures is ownership.

When a trader buys crypto on the spot market, they own the underlying Bitcoin or Ethereum. A spot trader that buys 1 ETH, will maintain 1 ETH regardless of whether the price rises or falls.

Perpetual futures work differently.

Instead of purchasing the asset, a trader opens a contract that tracks its price. In this instance, collateral secures a position, but the trader never actually owns the Ethereum. Once the position is closed, exposure to ETH’s price disappears.

In a severe scenario where exchanges go offline, spot holders maintain ownership. Meanwhile, perps traders do not have a claim to any underlying asset, just collateral.

2. Leverage: More Power With Less Capital

Another distinction between spot trading and perpetual futures is leverage. In standard spot trading, a dollar invested warrants one dollar of exposure to the asset.

If a trader buys $5,000 worth of Ethereum when it trades at $2,500, they own 2 ETH. Whether ETH rises or falls, the trader owns 2 ETH.

Perpetual futures allow traders to get additional market exposure via leverage.

Suppose a trader has the same $5,000 and wishes to gain levered long exposure to Ethereum with perps. If they open a long position at 5x leverage, their notional position is $25,000. When the price rises or falls, their profit and loss is magnified.

Compare a 10% ETH gain for the spot trader and the perps trader:

• $5,000 spot ETH position is now valued at $5,500 ($500 profit if sold)
• $5,000 5x levered long position is valued at $7,500 ($2,500 profit if closed)

When the price of ETH falls 10%, the losses are also magnified with leverage:

• $5,000 spot ETH position is now valued at $4,500 ($500 loss if sold)
• $5,000 5x levered long position is valued at $2,500 ($2,500 loss if closed)

Note: The above examples exclude funding costs and trading fees for simplicity.

Leverage allows traders to achieve the same notional exposure with less capital, making them more capital efficient. In the above example, if the trader maintains a portfolio of just $25,000 they would need to deploy their entire portfolio to get the same exposure as the 5x long.

However, capital flexibility comes with additional risk, as leverage magnifies losses equally and comes with liquidation risk.

3. Short Selling: Profiting From Falling Markets

Spot trading is primarily built for investors who expect asset prices to rise.

If the asset purchased on an exchange rises afterwards, a trader profits. If it falls, their investment loses.

Therefore, profiting from declining prices becomes more difficult. While some exchanges may allow traders to short via spot margin borrowing, it is complex and can be expensive.

Perps though make shorting assets much simpler.

If a trader believes the price of Bitcoin is going to fall, they open a short position. This provides traders with a trading tool for bear markets, where spot holders must decide to sell or hold assets through falling prices.

4. Costs: Holding a Position Isn’t Always Free

Another key distinction between perps and spot trading is the cost of keeping a position open.

With spot trading, costs are straightforward. Though there may be fees associated with purchasing an asset, once a trader has done so, there are typically no fees for holding it.

Perps work differently.

Given that the contracts do not expire, a mechanism called the funding rate keeps perps price aligned with the spot market. At regular intervals, every eight hours for crypto perps on Kalshi, payments are exchanged between long and short traders.

If funding is positive, long traders pay short traders. If funding is negative, the opposite is true. The rate changes based on market conditions.

An example:

If a trader has a $10,000 BTC long position and the funding rate is 0.01%, the funding payment would be approximately:

• Every 8 hours: $1
• Per day: $3
• Per month: ~$90

In this scenario the trader must weigh the position’s gains against the funding payments to determine whether or not they should keep it open.

Note: The funding rate will vary over time. The example considers a funding rate which stays at 0.01%.

By comparison, a trader that buys the same amount of exposure spot trading will not have an equivalent holding cost.

However, funding rates fluctuate, meaning a perps position could actually generate funding income.

For example, when funding turns negative, shorts pay longs funding payments. In this example, the trader generates income while maintaining the same exposure they would have had via spot trading.

5. Liquidation Risk

Perhaps the single biggest difference between spot trading and perps is liquidation.

A spot trader’s investments can lose value, but they own the underlying asset.

For example, if a trader buys 1 BTC on the spot market at $100,000 and it falls 60%, they still have 1 BTC valued at $40,000. If the market eventually recovers, the investment recovers in full.

Perps may not offer the same luxury. Leveraged positions must be backed by collateral (margin). If losses mount and become too large, clearing members may liquidate the position to prevent it from going negative.

If the same trader seeks $100,000 worth of BTC exposure, but does so via a 10x long position, they post $10,000 as their initial margin. This collateral can withstand some draw down, but as Bitcoin’s price approaches a 10% decline, it could be enough to trigger a liquidation, eliminating the trader’s exposure.

If Bitcoin later rebounds, the trader does not recover any of the losses.

Note: Liquidation prices will vary based on the clearing member’s maintenance margin requirements and fees.

6. Tax Considerations

Tax treatment is another potential difference between spot trading and perpetual futures, though rules vary based on a trader’s geography.

In many jurisdictions, holding crypto via the spot market does not create a taxable event. Instead, taxes may be triggered when the asset is disposed of via swapping or selling.

Perps may generate taxable events more frequently. Each time a position is closed, it could be treated as a taxable disposal, leading to many reportable events for active traders.

Additionally, funding payments may be treated as taxable income.

Note: Nothing herein should be treated as tax advice. Tax rules differ greatly between states and countries. It is important to consult a tax professional about how spot or perps trading may be treated in your jurisdiction.

When Is Spot Trading the Better Choice?

Spot trading is generally better for traders seeking a long-term investment.

It might also be better if a trader:

• Wishes to avoid leverage and liquidation risks
• Prefers not to pay potentially high funding rates
• Wants to earn yield on holdings via staking or lending
• Is in a tax-sensitive situation where a jurisdiction may treat perps trading as income, but spot as capital gains

When Are Perpetual Futures the Better Choice?

Perpetual futures trading may be better for those who want stronger capital efficiency and have an active trading style.

It may also be better if a trader:

• Wants to use leverage to amplify gains (leverage also magnifies losses)
• Needs to short the market in a simple manner
• Has a short-term view
• Wants to hedge an existing spot portfolio

A Combined Approach: Using Spot Trading and Perps

Spot trading and perps do not have to be isolated trading vehicles. Many experienced traders will use both simultaneously. One popular example is to hold a core spot portfolio for long-term investing, while using perps for shorter-term opportunities, or for hedging.

How to Use Perps to Hedge a Spot Position

Suppose a trader has accumulated BTC over the years and wants to hold it long-term. However, they believe the market could experience a short-term correction. They can use perps to hedge, or offset risk.

This strategy may be preferable, as selling Bitcoin might trigger taxes or conflict with long-term plans.

A Worked Example: Hedging a BTC Portfolio

Imagine a trader has 5 BTC worth $350,000 when Bitcoin trades at $70,000. They believe BTC could drop 20% in the next month before continuing its long-term uptrend.

Instead of selling the BTC, they open a 5 BTC short position with crypto perps, using $35,000 of collateral at 10x leverage.

In this example, the trader’s spot holdings and perps position offset one another.

Bitcoin Falls 20%

After opening the hedge, Bitcoin may decline from $70,000 to $56,000.

• Spot holdings: Loss of $70,000
• Perps short: Gain of $70,000 (less funding and fees)
• Net result: Portfolio remains largely unchanged thanks to the hedge.

In the case that Bitcoin rises, the trader would need to more actively manage their perps position to net no change in portfolio dollar value. For example, once Bitcoin has risen approximately 10%, their short position would be at risk for liquidation.

Note: These examples assume traders are using isolated margin. Learn more about margin in perpetual futures trading in our guide.

Cost of the Hedge

Using perps to hedge a spot portfolio comes with a cost: funding. To protect the position, the trader may have to pay the funding rate to traders on the other side, adding a cost as long as the position remains open.
