Hyperliquid’s synthetic SpaceX perpetual contract crashed 45%, liquidating over 400 traders in minutes.
Hyperliquid News
A synthetic perpetual contract tied to SpaceX's private market valuation on the Hyperliquid exchange dropped 45% on May 28. The SPACEX-USDH contract fell from $2,277 to a low of $1,254 within a single 30-minute window. It partially recovered to around $2,169 by the end of that period, according to Hyperliquid data.
The crash liquidated 405 users across 1,393 separate positions. Total notional losses came to $1.51 million within those 30 minutes. A single large sell order absorbed the available liquidity and sent the price into a freefall with nothing to cushion the move.
The market had seen very little activity in the hours leading up to the event. Over the prior 24 hours, the contract had generated just $4.87 million in total trading volume. Open interest stood at under $2.9 million at the time, leaving almost no buffer when the large order hit.
Retail Traders Bore the Brunt of the Crash
The median liquidated position held just $31 in margin. Most of those traders were using 3x #leverage with minimal capital behind them. That combination left retail participants with almost no room to withstand a sudden move of that size.
The SPACEX-USDH is a synthetic perpetual futures contract that lets traders speculate on SpaceX's estimated valuation ahead of a potential public offering. SpaceX remains a private company, and its shares trade only through private secondary markets restricted to accredited investors. Buyers of the contract receive no equity stake, shareholder rights, or ownership interest in the company.
Unlike perpetual futures on Bitcoin (BTC) or Ethereum (ETH), which are anchored to deep spot markets with continuous public pricing, the SPACEX contract has no public price benchmark. At settlement after the crash, the mark price of $2,132 still sat more than $220 above the oracle price of $1,908. That gap meant the contract continued to trade at a premium even after the liquidation event.
SpaceX is reportedly targeting a public listing in June 2026, which has drawn speculative interest in instruments tied to its valuation. The #Hyperliquid platform has seen growing activity in pre-IPO synthetic contracts as a result. May 28's event raised questions about whether adequate safeguards exist to protect retail traders in thinly traded, unbenchmarked markets.
