The synthetic SpaceX perpetual contract on decentralized exchange Hyperliquid suffered a 45% flash crash Thursday, wiping out over $1.5 million in leveraged positions within half an hour. The contract, ticker SPACEX-USDH, opened at $2,277 and plunged to $1,254 before recovering partially.
The 30-minute plunge
Traders who had bet on the pre-market asset saw their positions liquidated as the price collapsed. Onchain data from the incident shows a severe liquidity vacuum during the crash. The contract is a synthetic instrument that tracks SpaceX's private market value, not actual stock, and is only offered on Hyperliquid.
Liquidity vacuum on the DEX
The rapid drop exposed how thin order books can become for such bespoke synthetic assets. Unlike major crypto pairs, SPACEX-USDH lacks deep liquidity, making it vulnerable to large single-direction moves. The flash crash unfolded over roughly 30 minutes, with the price hitting a low of $1,254 before bouncing back.
What the onchain data shows
Blockchain records from the event indicate that the crash was amplified by a lack of buy-side orders near the opening price. As leveraged long positions got liquidated, the selling pressure accelerated, creating a feedback loop. The total value of liquidated positions exceeded $1.5 million, according to onchain analytics.
The incident highlights risks inherent in trading synthetic assets that represent pre-IPO companies. Hyperliquid, a decentralized exchange built on the Arbitrum network, offers a range of such perpetual contracts. The exchange did not comment on the crash.
Whether Hyperliquid will adjust its liquidity provision mechanisms for synthetic contracts remains an open question. For now, traders holding SPACEX-USDH face a volatile market with limited depth.
