You choose the leverage. You choose the size. You choose the direction. The one input that decides what happens to you when the trade goes wrong is the one you never set: whether the contract in your hands is filed as a perpetual future or a swap.
Same screen. Same funding rate. Same fifty-times number on the slider. Underneath sit two different rulebooks, and they disagree about what you are owed the moment something breaks.
This is a Kodex walkthrough with Eunha, who reads a contract the way she reads a person: by the question it is built to make you skip. Today that question is the one the order ticket answers for you. You will work through what a perpetual actually is, why its plumbing looks like a swap, why a US regulator just stamped one as a future, and what that single word changes for your protections, your tax bill, and your right to hold it at all.
Eunha does not pull up the chart. She pulls up the contract spec, scrolls past the price, and stops on one line near the bottom. Product classification. "Start here," she says. "This is the part the slider hides."
Strip the jargon and a perpetual is a position on a price that never has to settle.
A normal futures contract has an expiry date. On that date the position closes against a reference price, and the contract is finished. A perpetual deletes the date. You can hold it for an hour or a year, and nothing forces a settlement.
That creates a problem. If a contract never expires, what stops its price from drifting away from the asset it is supposed to track?
The funding rate is the answer. It is a small payment exchanged at a fixed interval, usually every eight hours, sometimes every four. It does not go to the exchange. It moves directly between the people holding the position: when the perpetual trades above spot, longs pay shorts; when it trades below, shorts pay longs. You can watch which side is crowded the same way you read open interest, because funding is the price of sitting on the popular side. The payment makes the crowded direction expensive, and that cost drags the contract back toward the real price. OSL's breakdown puts the formula simply: funding tracks the gap between the perpetual and spot, charged to whichever side is leaning too hard.
That is the entire engine. No expiry, and a recurring payment that keeps pulling the price back to reality. Kalshi's BTCPERP launched on exactly this design in the US in late May 2026 and cleared more than a billion dollars in notional within its first week, at up to fifty times leverage across thirteen contracts.
Hold onto the funding rate.
It is about to stop being a detail.
Look again at what funding actually is.
It is a recurring cash flow between two parties, set by the gap between a contract price and a reference, repeating for as long as the position stays open. Eunha asks the question that reframes the whole thing. "Where else in finance do two parties exchange a recurring payment pegged to a floating reference?"
A swap. That is close to the textbook definition of one.
This is the heart of John Lothian's argument that perpetuals are swaps in everything but name. The funding payments, he points out, create ongoing cash flows between the parties, which is what a swap does and what a dated future does not. He pushes the point one step further: the windows when funding is calculated could hand someone an incentive to nudge the price right around the moment the payment is set.
A recurring bilateral payment, with a settlement window worth gaming. Not a future's one-and-done expiry, but a swap's open-ended stream.
The mechanics lean swap. Hold that thought, then watch what the regulator did with them.
Eunha is not interested in winning the swap-versus-future argument. She is interested in who gets to decide it, because that is the part that touches your account.
Here is the move that started the fight. Kalshi, a CFTC-overseen exchange better known for prediction markets, self-certified and listed BTCPERP as a futures product with its US regulator. Not a swap. A future. That classification did not fall out of the cash-flow mechanics. It came from a filing.
Kalshi's Udesh Jha defends the label on different ground than the plumbing. The contracts are exchange-traded, centrally cleared, and built to track the underlying spot market, which is how futures behave. He adds that Kalshi calculates funding continuously across the cycle instead of at a single closing print, which is meant to remove the exact manipulation window Lothian flags.
So you are left with two true descriptions of one contract. By its internal cash flow it acts like a swap. By its venue, its clearing, and its filing, it is a future. CoinDesk, covering the dispute, noted that the outcome could shape customer protections, market structure, and tax treatment all at once.
The contract did not change.
The label did.
And how a product is regulated, not how its cash flows behave, is what every protection downstream is keyed to.
This is where an industry classification fight lands on your balance. Eunha puts it plainly: three things move the instant the word changes, and none of them appear on the chart.
The first is who is allowed in, and what stands behind them if it fails. The second is how you are taxed. The third is how much rope you are handed. She lays the two regimes side by side, because the distance between them is the whole reason the label is worth fighting over.
| What you are reading | If it is a regulated future | If it is a swap |
|---|---|---|
| Who can hold it | Retail, through a registered intermediary on a regulated contract market | Generally gated to large institutions and qualified participants |
| Customer-fund protection | Segregated customer accounts and a clearing regime designed for retail failure | Bilateral terms; your protection is the counterparty, not a retail rulebook |
| US tax treatment | Points toward Section 1256: a 60% long, 40% short split, marked to market each year | Generally ordinary treatment, with no 1256 split |
| Leverage reaching you | Exchange-set, and here it reaches retail at up to 50x | Negotiated, and rarely pointed at a retail account |
Four rows, one contract, two worlds. Read down the regulated-future column and the appeal is obvious. A retail person gets an instrument with clearing and segregated funds behind it that used to sit behind an institutional gate.
Read across the tax row and the stakes turn concrete. US-regulated futures on a designated contract market can qualify for Section 1256 treatment: that 60/40 split, with positions marked to market at year end. Swaps generally do not get the split. The future label points toward the friendlier regime.
It only points. The IRS has not ruled on how perpetual futures specifically are taxed, and a contract with no expiry strains the rules written for ones that settle. Treat the label as the thing the tax answer hangs on, not as the answer.
The label is not paperwork. It is the rulebook that decides what you are owed.
Not everyone reads retail access as good news.
Terry Duffy, who runs the CME, called these products a disaster waiting to happen. His warning is specific: fifty-times leverage pointed at retail accounts is the kind of structure that detonates, and he reached back to 2007 to describe the shape of the risk. He also argued the CFTC rushed its review.
Eunha does two things with that quote at once. She takes the risk seriously, and she names the interest sitting behind it.
The risk is real. Fifty-times leverage on a contract that reprices every block, run into order books that thin out fast, is how a small move against you becomes a full liquidation before you have decided anything.
The interest is real too. The CME is the incumbent US-regulated venue for crypto derivatives, and a retail-facing rival arriving under the same regulated banner is a direct threat to that position.
Both can hold at once. A warning can be self-interested and still be correct, and what you do with it is separate from why he said it. The useful part is the one that survives either motive: regulated tells you which rulebook governs the venue. It does not tell you the position is safe.
Regulated is not the same word as safe.
It never was.
Strip away Kalshi, the CME, and the acronyms, and Eunha is left with the habit she opened on: read the category before the chart.
Four questions carry it. What is the funding mechanism, and how often does it charge you to hold? What protection regime governs the contract, retail-grade with segregated funds, or institutional terms where your counterparty is the only protection you have? How is it taxed, and is that actually settled or merely implied by a label? And what is the real leverage ceiling the venue will hand you?
You answer those before you size the position, not after the liquidation notice arrives. Kodex builds this into the Survival Framework as a reflex rather than a trading tip: the contract's legal shape is part of the trade, the same way open interest and liquidity are. The label is not trivia. It is the part of the position that decides what you can do when you turn out to be wrong.
Eunha closes the contract spec. The chart is still sitting there, untouched.
"You were never choosing a number," she says. "You were choosing whose rules catch you when you fall."
Read the label first.
The leverage is the easy part.
By its mechanics, a perpetual behaves like a swap. The funding rate is a recurring payment between holders pegged to a floating reference, which is how swaps work. By its venue and its filing, Kalshi's BTCPERP is listed as a regulated future. The same contract fits both descriptions, which is precisely why the classification is contested rather than obvious.
Yes. Kalshi operates under CFTC oversight and self-certified BTCPERP as a futures product. Regulated means a defined rulebook governs the venue, its clearing, and customer funds. It does not mean the position carries low risk, and the leverage on offer is exactly where that distinction bites.
This is unsettled. US-regulated futures on a designated contract market can qualify for Section 1256 treatment, a 60/40 long-short split marked to market each year, while swaps generally do not. The future label points toward 1256, but the IRS has not ruled on perpetual futures specifically, and the missing expiry complicates the usual rules. Treat it as an open question and get advice for your own situation rather than assuming the friendlier outcome.
Because protections, eligibility, and tax all key off the legal category, not the screen. A regulated future can reach retail with segregated customer funds and a clearing regime behind it. A swap is generally restricted to institutions on bilateral terms. The label decides what you are owed when something goes wrong, which is the one moment it was ever going to matter.
