Perpetuals tied to SK Hynix hit by flash crash to $900 on Hyperliquid

Perpetual futures on the South Korean chipmaker's American depositary receipts plunged 20% in one minute before quickly rebounding above $1,000.

Perpetual futures tied to SK Hynix on the Hyperliquid exchange plunged about 20% in one minute before quickly rebounding above $1,000. The flash crash in the USDC-denominated contract preceded a sharp selloff in South Korea, where SK Hynix shares fell 14% and the Kospi index dropped 11%. The episode comes amid thin overnight crypto liquidity and broader weakness in AI-related stocks, including a 5% drop in Nvidia after a report on its potential $250 billion financial backstop for an OpenAI-linked data-center project.

Perpetual futures tied to SK Hynix, a South Korean chipmaker whose American depositary receipts debuted on Nasdaq earlier this month, suffered a flash crash on Hyperliquid shortly before the underlying share price came under pressure in its home market.

Between 23:00 UTC and 23:01 UTC, the price of perpetuals tracking the Seoul-traded stock crashed 20% to $900, according to data from Hyperliquid. The price rebounded to over $1,000 the very next minute and was recently priced at $1,092. The contract is traded and denominated in dollar-pegged stablecoin USDC.

An hour later, the Korean stock market opened on a negative note, led by chipmakers. By the end of the day, SK Hynix shares had dropped by 15% to 1,550,000 won ($1,762). Other losers included Samsung Electronics and carmaker Hyundai Motor. The benchmark Kospi index fell 11%.

SK Hynix ADRs, 10 of which equal one share, fell 4.5% in pre-market trading to $136.51.

Hyperliquid, the leading perpetuals-focused decentralized exchange, has emerged as a hot favorite of traders looking to express their view on traditional assets, especially since the onset of the Iran war in late February. The exchange had not responded to a request for comment by publication time.

Flash crashes on crypto exchanges are quite common, especially between the U.S. market close and the opening of markets in China, South Korea, and elsewhere in Asia, because liquidity tends to be relatively thin compared with other market hours. Liquidity refers to an exchange’s ability to absorb large buy and sell orders at stable prices.

SK Hynix, one of the world’s largest suppliers of high-bandwidth memory (HBM) chips used in Nvidia’s AI processors, has taken a beating this month, falling by nearly 48% from the peak of 1,947 won reached on June 26.

It is not alone. Sentiment for AI stocks has also weakened on Wall Street. On Monday, Nvidia shares slid 5% after a Wall Street Journal report said the AI-chip maker could provide a financial backstop of about $250 billion for an OpenAI-backed data-center project.
