SKHX Flash Crash Hits Hyperliquid
A large leveraged SKHX position on Hyperliquid is driving extreme price swings and liquidation cascades.
The SK Hynix perpetual (SKHX) on Hyperliquid flash-crashed 17.9% on 28 July after a single share printed at ₩1.272m (~$867) in thin pre-market trading on Nextrade — roughly 30% below the prevailing price, halting trading there. The oracle followed the print down, breaching the backstop liquidator and forcing over $26m in liquidations — reportedly more in four hours than all of Binance. The largest short's unrealized profit swelled to $6.1m. Hyperliquid says the market is operated by Trade.xyz under HIP-3; Trade.xyz is investigating, and prices have normalized.
Hyperliquid: one weird trade in Seoul, $26 million gone in minutes
One trade. A single SK Hynix share printed at ~$867 in a thin Korean pre-market session — about 30% below the real price. Korea's exchange halted. The oracle didn't — it chased the print, SKHX cratered 17.9%, and $26m in leveraged positions were force-closed. Reportedly more liquidations in those four hours than the whole of Binance.
This is the real cost of putting stock perps on perp DEXes. The contract has to trust an external price feed, and any feed can be broken by one illiquid order at an inconvenient hour in Seoul.
This wasn't even Hyperliquid's oracle. Under HIP-3, the team that deploys the market — here, Trade.xyz — pushes the price inputs, and its two inputs outvote the protocol's one. Hyperliquid carries the headline risk for markets it doesn't operate.
And it's not a one-off. In May, a bad data feed took the SpaceX perp down 45% in half an hour. None of this changes where crypto-native speculation is heading. But the next weird trade is already out there — the only question is which market's oracle catches it.
