Hyperliquid's SPACEX-USDH perpetual contract suffered a violent flash crash on Thursday afternoon, plunging from an open of $2,277 to a low of $1,254, a near-45% collapse, within a single 30-minute window before partially recovering to around $2,169. The move liquidated 405 users across 1,393 positions, wiping $1.51 million in notional value, Hyperliquid data shows.
What makes the episode particularly striking is the volume concentration. Over the past 24 hours the contract had drifted quietly, generating just $4.87 million in total trading volume across an open interest base of under $2.9 million. Then one candle absorbed what was likely the bulk of that entire figure and the market had no depth or liquidity to absorb it.
The median liquidated position held just $31 in margin, pointing to a retail-heavy user base taking on 3x leverage with minimal cushion.
Unlike perpetual futures on Bitcoin or Ethereum, which anchor to deep, liquid spot markets, the SPACEX contract has no public price benchmark, with SpaceX shares trading only through private secondary markets gated to accredited investors.
At settlement, the mark price of $2,132 still sat more than $220 above the oracle price of $1,908, implying the contract remained at a premium even after the carnage.
SpaceX is targeting an IPO in June.
