Perpetual options are a new type of financial contract gaining significant attention in crypto markets today. They are special for one simple reason. They never end. A normal option has a fixed end date. After that date, the option is no longer available. A perpetual option has no end date. You can hold it for as long as you wish.
This may sound like a small change, but it is not. Removing the end date changes how the contract works, how people trade it, and, most of all, how you put a value on it. That last point is the big one. Traders, regulators, and even courts now want to know how to price these contracts fairly.
This article explains what these contracts are, why they are growing fast, and how experts try to value them. It also looks at why all this matters when money and law come together.
What are Perpetual Options?
An option is a simple idea. It gives you the right, but not the duty, to buy or sell something at a set price. A call option lets you buy. A put option lets you sell. Most options come with an expiry date. You must use the option before that date, or it loses all its value.
A perpetual option takes away the expiry date – the right to buy or sell stays alive. You do not need to keep buying new contracts when the old ones run out. Buying new contracts repeatedly is called rolling over. Many traders do not like it, because it costs both time and money.
Some people call these contracts everlasting options. This name came from a 2021 paper by Dave White and Sam Bankman-Fried at the firm Paradigm. Their work built on a close cousin of the option, called the perpetual future.
A perpetual future, often just called a perp, lets you bet on the price of an asset without owning it. Like the perpetual option, it has no end date. To keep its price close to the real market price, it uses a small regular payment called a funding rate. Traders on one side pay traders on the other side. If the price drifts too far, the funding rate pulls it back in line. Everlasting options work in much the same way. The main difference lies in how the funding payment is calculated.
There is also a special version called a perpetual power. The best known one is called squeeth, short for squared ether. It gives you exposure to the price of ether multiplied by itself. So if ether doubles, your gain grows four times over. These products are clever, but so far only a few of them have found real use.
Why Perpetual Contracts are Growing Fast
Crypto markets never close. They trade every hour of every day. Old-style contracts with fixed end dates were built for markets that shut at night and on weekends. Those end dates push traders to close or roll over their trades on a set schedule. This brings cost and stress. Perpetual contracts remove that problem. You open one trade and keep it open for as long as you like.
This one benefit has helped make perpetual futures one of the most traded products in all of crypto. New trading platforms have pushed this growth even higher. Some crypto wallets now let people trade perps right inside their own apps.
The idea is also moving into other assets. A few exchanges now offer stock perpetuals. These contracts let people bet on shares like Tesla or Nvidia without owning them. The contract never expires, and a funding rate keeps it close to the real share price.
Regulators in the United States are watching closely. In May 2026, the main US derivatives regulator, the CFTC, approved the first bitcoin perpetual futures contract for the platform Kalshi. This was a big moment. It brought a popular crypto product into the regulated US market for the first time.
But, not everyone was happy. In June 2026, CME, the largest financial exchange market in the world, sued the CFTC. At the center of the fight is a simple but very important question: Is a perpetual contract a future or a swap?
The answer to this question changes everything. It decides which rules the contract must follow, how much tax people must pay on it, and how closely the government will watch it. As we will see soon, this question is also very important for deciding how much the contract is worth.
How to Value Perpetual Options
Now we reach the hard part. How do you set a price on a contract that never ends?
For normal options, the world has a famous tool. It is called the Black-Scholes model. Banks and traders have trusted it for many years. But this model needs an end date to work. A perpetual option has no end date. So, the old formula simply does not fit. This is the core problem in perpetual options valuation.
Researchers found a clever way around it. The team at Paradigm showed that a perpetual option is equivalent to a basket of options that expire on different dates. The smart part is in the weights. The basket holds half of an option that expires today, a quarter of one that expires tomorrow, an eighth of one that expires the day after, and so on. The shares keep getting smaller. When you add up the value of the whole basket, you get the value of the perpetual option.
The funding rate also plays a big role. It works like a running cost for holding the contract. A higher funding rate makes the contract more costly to hold over time. Price swings, or volatility, matter as well. When the asset jumps around a lot, the option is worth more, all else equal.
In the world of decentralized finance, known as DeFi, there is one more problem. These systems need a live price feed, called an oracle, to tell them the asset’s current price. If the oracle is wrong or slow, the contract’s value falls apart. The amount of money in the market, or the liquidity, also shapes the price. Thin liquidity makes the contract harder to value and harder to trade.
So, there is no single magic number. Experts use a mix of mathematical models, computer simulations, and real market data to reach a fair value. Each method has its own strengths and weaknesses.
Valuing These Contracts in Other Markets
A contract with no end date is an older concept than crypto. In the early 1990s, Robert Shiller suggested perpetual claims on things like house prices and other economic data. He wanted to build markets for hard-to-trade assets. So, the core idea has deep roots.
Today, the same idea is spreading well beyond crypto. Stock perpetuals are one early sign. Many researchers believe the same pricing methods can apply to shares and to commodities like oil or gold. As these contracts reach more markets, the need to value them clearly and fairly will only grow.
Why Valuation Matters in Legal Disputes
This is where the topic becomes more than a trading story. When money is on the line, valuation turns into a legal question.
Look again at the fight between CME and the CFTC. The whole case rests on what a perpetual contract truly is. If a court calls it a swap, one set of rules applies. If a court calls it a future, a very different set applies. To settle this, courts often need an expert who understands both the math and the market.
There are other disputes too. When a trader loses money, how do you measure the loss on a contract that never ends? If someone pushes the funding rate or feeds a false price into the oracle, is that market abuse? When two sides cannot agree on the fair value of a perpetual option, who is right? These are hard questions. They call for an expert who can explain complex financial products in plain, honest terms.
I work on these very kinds of problems. With a strong background in financial economics and the pricing of complex products, I can help courts and legal teams make sense of new and complex instruments.
Final Thoughts
Perpetual contracts have changed crypto markets in a very short time. They are easy to hold but hard to value. As they spread into shares and other markets, and as courts and regulators take a closer look, the need for clear, reliable valuation will keep rising. For anyone who faces a dispute in this space, knowing how to value perpetual options is no longer a side topic. It sits at the very heart of the matter.
