- Stock perpetual futures hold no shares, so no company pays them dividends; Binance turns a cash dividend into one funding settlement in which shorts pay longs the gross dividend over the mark price, with the funding cap skipped.
- The payment leaves a short's margin before the ex-date price drop that offsets it: on 29 September 2026 SAMSUNGUSDT settled minus 1.66% at 08:00 Seoul time and its mark fell about 1.6% by the open, while trade.xyz pays nothing directly and leaves its longs to carry the drop.
- Before an ex-date, read the venue's corporate-action rule, convert its settlement hour and divide the dividend by your margin rate; SK hynix's reported 23,000 won would be about 1.8% of a position, more than a third of a 20x short's margin.
A stock perpetual future owns no shares, and a dividend can still take money out of one side of it. SK hynix may be about to show how much. A Dong-A Ilbo report on Monday, 26 October, said the company was pursuing a special dividend of about ₩16 trillion, paid for with the sale of its Kioxia stake. In a notice to the SEC the same day, SK hynix said "no matters have been determined". Its board is due to decide with Wednesday's third-quarter results. Press reports put the payout near ₩23,000 a share.
So do stock perpetual futures pay dividends? Not the way a share does, since no share sits behind the contract and the company sends it nothing. Someone still ends up carrying the dividend, though. Binance moves it in cash, from shorts to longs. On trade.xyz, which runs its own SK hynix perpetual on Hyperliquid, nobody pays anybody, and the dividend stays inside the price. Which side carries it, and at what hour, is set by each venue's rulebook rather than the share register.
On Binance, a payout that size already has instructions. At eight in the morning Seoul time on the ex-dividend date, everyone short SKHYNIXUSDT pays everyone long it. Each short hands over about 1.8% of the position in one settlement, with the contract's usual cap on funding switched off. Across Monday evening's open positions of about $439 million, that comes close to $8 million.
It falls due an hour before the Korea Exchange opens.
Risk, to Ava, is a sum you can do in advance. If a number is going to hit your account at a known hour, she wants it worked out before the hour arrives. A dividend on a perpetual is exactly that kind of number. With her you will work through both venues' rules on SK hynix, then the arithmetic a position should pass before any ex-date.
Ava converts the hour before anything else. In UTC, Seoul's eight o'clock is eleven the night before. A UTC screen shows the payment on the evening before the ex-date. In Europe it lands around midnight, in New York before dinner.
Why would a stock perpetual with no shares owe a dividend?
"Look at the share first, because the share is what the perpetual copies," Ava says. On the ex-dividend date, a buyer of SK hynix no longer gets the payout, so the price opens lower by roughly the dividend.
That drop isn't news, it's bookkeeping.
Cash that belonged to the company now belongs to its shareholders. The perpetual sees none of that cash, only the price, which it follows through an index. Funding, a payment between longs and shorts at set intervals, keeps the contract close to it, so when SK hynix opens ₩23,000 lighter, the index drops and the perpetual drops with it. If nothing else moved, a long would lose 1.8% that no market event caused. A short would pocket the same 1.8% for doing nothing.
Shareholders are covered by the dividend they are owed. A perpetual's holders are owed nothing, so the venue has to decide what to do about the gap. Binance and trade.xyz decided differently. Where you hold it picks the side the morning lands on.
"On one venue the dividend is a bill with a time printed on it. On the other it's a discount you had to bargain for when you bought," Ava says.
How Binance bills a dividend to the shorts
Binance answers with one formula. It sits on a methodology page the exchange published in April and last updated on 1 October. The settlement's funding rate is minus the gross dividend per share, converted into the contract's currency, divided by the mark price at that moment. A negative rate means shorts pay longs. Binance is not the payer here but the clerk, moving money from one side of the book to the other. The page gives its reason without decoration: short position holders "will pay long position holders to neutralize the price gap".
Binance also lifts the funding cap for this one settlement. On SKHYNIXUSDT an ordinary settlement can't move more than 0.5% either way, and one comes every four hours. For the dividend, "the standard funding cap logic is intentionally skipped", the page says. Its adjustment "could be higher than the funding cap". A 1.8% dividend arrives as 1.8%, in one payment.
The clock matters as much as the formula. For a Korean share, all of it happens on the ex-date, in Seoul time. From four in the morning, funding settles hourly. At half past seven the contract turns reduce-only: positions can be cut or closed, but not opened or enlarged. The mark price must also stay within 1% of the index. At eight the hourly funding settles, then the dividend. A minute later the restrictions lift. A US listing runs the same steps on the evening before its ex-date, New York time, with the payment at eight in the evening.
Samsung's dividend went through this routine on 29 September. Binance's public funding history for SAMSUNGUSDT shows the hourly payment at eight that morning, close to zero. A second later comes the dividend: minus 1.66% of the mark. By the time Seoul opened, the mark was about 1.6% lower.
So the shorts paid first, and the price paid nearly all of it back. "One of those numbers came off a timetable, and the other came off a market," Ava says. That morning the market cooperated. Neither side came out of the hour richer for the dividend, which is what the rule was written to do.
Look at what the venue gives itself to make that happen. It rewrites its own funding schedule for a night and freezes new positions for half an hour. It lifts the cap that binds every ordinary settlement, all to stand in for a payment it never receives. SK hynix decides what its shareholders get.
What happens to everyone who never owned the share is the venue's call.
Why a 1.8% charge can close a 20x short
Now run SK hynix through the formula, with you on the short side. Take the reported ₩23,000 against Monday's close of ₩1,290,000. The dividend comes to 1.78% of the price (computed), roughly three and a half times the cap on an ordinary settlement. Monday's largest regular payment was under 0.03%.
Leverage turns that percentage into a share of your margin. At 20x the margin behind a position is 5% of its size, so the payment takes more than a third of it. At 10x it takes close to a fifth, and at 5x under a tenth. "The dividend is the same size at any leverage. Your margin isn't," Ava says.
Say you are short $10,000 at 20x, on $500 of margin. At eight in Seoul, about $178 leaves that margin. If the price then falls by the dividend, as Samsung's did within the hour, you earn about as much back. Across the morning, that nets out near zero. For the stretch in between, though, the whole position rests on roughly $322, and your liquidation price has moved toward the market by the full payment. The risk isn't the amount, it's the order things happen in.
A short already near its liquidation price can be closed out by the payment itself, before the move that would have repaid it.
Before that, the timetable narrows your options. From half past seven you can still cut or close the short, but you can't add to it. Nobody can open a new position on either side. Until the payment, closing is the only move left. In UTC, that half hour starts at half past ten the night before.
A dividend is the most orderly money a company sends out, approved by a board and dated weeks ahead. On a 20x short it arrives as a payment bigger than the contract's own cap allows, at an hour when the share itself can't trade.
What does a long get where nobody pays?
On trade.xyz, the long is the side holding the gap. The venue lists SKHX, a perpetual on SK hynix's Seoul share, and on Monday evening it carried about $316 million of open positions, with leverage up to 10x. Its corporate-actions page says perpetual holders "do not receive dividends directly". Instead, the dividend's effect is meant to show up "in pricing and funding through arbitrage between the perpetual and the underlying shares". Funding payments, the page adds, "depend on market conditions" and "are not fixed dividend payments".
"It's a sentence about the price, and you aren't in it," Ava says. When the share opens lower on the ex-date, SKHX follows.
Nobody sends the long anything.
Whatever covers the drop has to have come earlier, as funding received before the ex-date or a lower price paid at entry. The market sets both, and Samsung's ex-date shows how much it supplied. In the seven days before eight o'clock on 29 September, Hyperliquid's public funding history shows trade.xyz's Samsung perpetual paying its longs about 0.8% of their position (computed). That same morning, Binance's longs got the estimated dividend in a single payment of 1.66%. The longs on trade.xyz were paid not by a rule but by a market, which returned about half over a week. Nothing in the venue's rules promised more.
Make yourself the 10x long on SKHX when an SK hynix dividend goes ex. A 1.8% gap at the open takes close to a fifth of your margin, and no settlement follows to pay it back. On Binance that risk sat with the short. Here it sits with you.
A dividend belongs to whoever owns the share, because the share is a claim on the company. A perpetual is an agreement between strangers, kept by a venue. On that kind of contract the dividend is not a right but a policy, and the venue chooses which stranger is made whole.
What each SK hynix instrument receives on the ex-date
Hold SK hynix five ways, and the same ₩23,000 reaches you five different ways, if it reaches you at all.
| How you hold it | What you get | Who pays | When |
|---|---|---|---|
| SK hynix share, Seoul | The dividend in cash, less any withholding tax | SK hynix | On the company's payment date |
| SKHYB, tokenized ADR on Binance spot | Extra tokens bought with the dividend net of withholding, fees and costs, if it follows Binance's bStocks practice | SK hynix, through the ADR and Binance | After Binance's snapshot |
| SKHYNIXUSDT, Binance perpetual on the Seoul share | Long: the gross dividend in cash. Short: pays it | The shorts | 08:00 Seoul time on the ex-date, cap skipped |
| SKHYUSDT, Binance perpetual on the US ADR | The same rule, applied to the ADR | The shorts | Binance's US timetable: 20:00 New York time, the evening before the ADR's own ex-date |
| SKHX, trade.xyz perpetual on the Seoul share | Nothing directly | Nobody; the long carries the price gap | At the open, offset only by earlier funding |
Only the shareholder is paid by the company. Every other holder gets a number a venue computed, and the numbers disagree. The tokenized ADR comes nearest to the share, and even there the dividend arrives thinned, as extra tokens bought after withholding, fees and costs. When a token pays more than the company does, there is usually a loan attached.
The gap between gross and net is where a hedge leaks.
Say you hold the tokenized ADR and short the ADR perpetual against it, to own the spread between two prices for one share. Come the ex-date, you owe the dividend gross on one leg and collect it net on the other. Nothing in the perpetual's formula allows for withholding.
The two Binance perpetuals need not even settle on the same night. SKHYNIXUSDT pays on Seoul's ex-date. The ADR perpetual would follow Binance's US timetable, keyed to the ADR's own ex-date, which the depositary sets and which need not match Seoul's. Anything priced off a perpetual inherits its venue's calendar too, and a perp option is one example, because it settles against the contract rather than the share.
When the dividend is still an estimate
Korea's calendar can put the ex-date ahead of the amount, and Samsung's did. Samsung had promised about ₩30 trillion in third-quarter dividends, with the per-share figure to come only after its late-October results. So on 29 September Binance charged an estimate: ₩4,500 a share, according to coverage of its notice. It promised a true-up within a week of Samsung's final figure. Almost a month on, both are still due.
The methodology page files unpredictable payouts under funds. ETF dividends, it explains, are hard to know in advance, "unlike stocks".
Samsung's calendar disagreed.
For ETF perpetuals the estimate is final. Binance announces it four to twelve hours before the ex-date and "will not redistribute the payout difference". Leveraged ETFs get no adjustment at all, so a long on one of those carries the dividend gap the way an SKHX long does.
SK hynix's board is due to announce its shareholder returns on Wednesday, 28 October, and if they include a special dividend, the amount and a record date should come with them. The ex-date follows, and the arithmetic stops being hypothetical.
Until then, ₩23,000 is a newspaper's number.
How much of your margin does a dividend take on a stock perpetual?
Ava's sum fits on the back of an order ticket. Its first input comes from a page no ticket shows: the venue's corporate-action rule. Nothing else tells you which side pays, or whether anyone does. With the rule in hand, find the ex-date. Convert the venue's settlement hour into your own time zone, and do the same for any window when the contract stops taking new positions. For Binance's Korean contracts, it opens at half past seven, Seoul time.
None of it means much until you know the size, and the size takes two divisions. The dividend over the price is the share that changes hands. That share over your margin rate, 5% at 20x or 10% at 10x, gives the bite out of your margin. On a Binance short, set the bite against the distance to your liquidation price, because the payment shortens that distance by about the dividend's percentage before the price can lengthen it again. On a trade.xyz long, the same percentage comes off at the open, and only the funding the market paid you beforehand offsets it.
You can cut the position until the bite leaves room you're comfortable with, or add margin before the window opens. You can also close ahead of it and come back after. Ava books the settlement as a price move announced in advance, because on Binance it is one.
The answer to whether stock perpetual futures pay dividends, then, sits not in the company's dividend history but in a paragraph of each venue's rulebook. On Binance it is a formula with a timestamp, run before the Korea Exchange opens. On trade.xyz it is one sentence saying nobody pays. The venue that writes the paragraph also decides how long the contract lives, which tells you whose instrument it is.
SK hynix decides on Wednesday what its shareholders will receive. What everyone holding a contract on the share receives was settled long before, in rulebooks anyone can read tonight.
Short Bitcoin's perpetual at 20x in the simulator and, before anything executes, read the distance the Liquidation Risk panel shows. Knock 1.8 points off it, the bite a dividend of SK hynix's reported size would take, since no dividend will ever reach this ticket to do it for you. Then bring the leverage down until what is left is a distance you would sleep through.
