Chipmaker Stock Perps Lose $52 Million in 10 Minutes While Wall Street Is Closed

What happened on Saturday

On Saturday, October 17, at 21:21:59 UTC, heavy selling hit the SanDisk and Micron perpetual contracts on Binance. In less than a second the wave reached Hyperliquid, where these contracts are listed by the Trade XYZ platform. According to CoinDesk, about ten addresses opened shorts there on six chip contracts at once within 1.8 seconds.

From there, the usual leverage mechanics took over. Between 21:22 and 21:32 UTC, CoinGlass data shows about $51.6 million in positions were forcibly closed. Roughly $38 million of that was long bets. In the first minute alone, SanDisk saw $21.9 million in trades on Binance and $3.1 million on Trade XYZ.

The SOXS and Micron amounts are CoinGlass data as reported by Crypto Briefing; for the first three contracts, the CoinDesk and Crypto Briefing figures nearly match. SOXS rises when chips fall, so its liquidations were most likely shorts. No obvious trigger for the selling has turned up. Memory chip stocks had been swinging all week: on October 13, amid a slump in Asian chip stocks, about $800 million in positions were liquidated on crypto exchanges, including nearly $20 million in SanDisk contracts.

How a "stock" crashes while the exchange is closed

A perpetual contract on a stock gives you no shares at all. You don't own SanDisk, you bet on its price with leverage, and the platform decides which price counts as the right one. On weekdays it's simple: the price comes from the US exchange. On weekends the exchange is closed, there's no outside price, and the platform draws one itself. Coins in your own wallet, say ones you got through a no-KYC crypto exchange, don't have this problem, since there's nobody to liquidate them.

Trade XYZ spells this out in its docs. During closed hours the oracle switches to an "internal session": it starts from the last outside price on Friday evening and then follows prices in the platform's own order book, smoothing them over half an hour. To keep the price from running away entirely, it's held within bounds: for SanDisk, Micron, SK Hynix and SOXL that's plus or minus 10% of the reference price, and the bound can be shifted once. As soon as outside quotes are available again (for SanDisk, Micron and SOXL that's Sunday, 20:05 New York time), the oracle switches back to the outside price.

So on weekends the price of such a "stock" is set by traders themselves in a thin order book. If someone sells hard and buyers are scarce, the price falls through the floor, and a liquidation cascade finishes the job. Under Trade XYZ's rules, while there are no outside quotes, the price is formed by the platform's own order book, and on Saturday that worked out in the worst possible way.

It has happened before

• July 2026. On July 27 at 23:01 UTC, the SK Hynix liquidation price on Trade XYZ fell about 19% because of a single trade in the thin Korean pre-market. About $60 million in positions was liquidated. The platform said the oracle worked as specified, but it covered users' losses as a one-off decision.
• December 2025. Over a weekend, a short of about $10 million in the XYZ100 index contract knocked the price down about 3.5% and wiped out around $13 million in longs.

As of publication, neither Trade XYZ, Hyperliquid nor Binance had said anything about compensation for the Saturday crash.

Why this market has grown so fast

"Stocks" on crypto exchanges have turned into a huge business in a year. According to The Block, about $433 billion went through perpetual contracts on traditional assets on Binance in August 2026, with roughly 79% of that in stocks. Trade XYZ set a record in July, with about $100 billion for the month.

The appeal is obvious: you can trade Nvidia or SanDisk with leverage around the clock, with no brokerage account, paying in stablecoins. But that round-the-clock access is the trap, because in the hours when the real market is asleep your position lives on prices that nobody checks except the platform itself. Leverage on these contracts reaches 10x on Trade XYZ and can go even higher on other platforms.

How not to be the next liquidation

• Don't hold leverage on "stocks" over the weekend. If you need the position until Monday, cut the leverage or close it on Friday.
• Set your stop with room to spare. The internal price can drift 10% or more from Friday's close before external quotes come back.
• Don't confuse a contract with ownership. A share bought through a broker without leverage can't be liquidated in a minute. A perpetual contract can.
• Keep savings separate from trading. Money that isn't in a trade is safer in a stablecoin or coins in your own wallet than on an exchange margin account. We've covered the difference between custodial and non-custodial wallets separately.

If after a week like this you want to lock part of your position in dollars, you don't have to do it on the same exchange: you can get stablecoins straight to your own address.

Most often people exchange bitcoin to USDT TRC20 without registration to ride out the storm in dollars, and once the market calms down, it's just as easy to buy bitcoin back with USDT.

FAQ

What happened to chipmaker stocks on crypto exchanges on October 17?

On Saturday evening, with the US stock market closed, perpetual contracts on SanDisk, Micron, SK Hynix and semiconductor funds were sold hard on Binance and Hyperliquid. About $52 million in positions was liquidated in ten minutes, roughly $38 million of it long bets.

Where does a stock's price on a crypto exchange come from on weekends?

The platform draws it itself. During closed hours, Trade XYZ calculates the price from its own order book, starting from the last outside price on Friday and within set bounds. Once outside quotes are available again, the price returns to the exchange price.

Will traders be compensated for their losses?

As of publication, there had been no statements about the Saturday crash. In July 2026, Trade XYZ covered losses after a similar SK Hynix crash, but called it a one-off decision.

Can you lose more than what's in your account?

On most platforms a position is closed before the loss exceeds the collateral, so what you usually lose is the margin posted for that position. But at 10x leverage, a 10% drop already eats all of it.
