$1.5 Million Wiped Out as Hyperliquid's SpaceX Pre-Market Perpetual Flash Crashes 45%

SPACEX-USDH on Hyperliquid dropped from $2,277 to $1,254 within about 30 minutes, a nearly 45% collapse, before recovering toward $2,157. Thin liquidity caused cascading liquidations, totaling $1.51 million across 1,393 positions held by 405 users. The liquidated positions had a median margin of $31, indicating heavy skew toward high-leverage retail participation. SPACEX-USDH is a synthetic perpetual tied to the implied valuation of SpaceX, which is private and lacks a public price benchmark ahead of an expected IPO around June 11. The market was built using Hyperliquid’s HIP-3 architecture by Ventuals, and compensation was pledged within 48 hours after the incident.

"The SPACEX-USDH contract on Hyperliquid plunged 45% on May 28, dropping from $2,277 to $1,254. Thin liquidity triggered $1.51 million in liquidations across 1,393 positions held by 405 users. The flash crash once again exposed the risks of onchain price discovery ahead of SpaceX's June public IPO."

"Onchain Data Shows Severe Liquidity Vacuum in Pre-Market Contract SPACEX-USDH, a synthetic pre-market asset, plunged from an opening price of $2,277 down to a low of $1,254 within a 30-minute window, representing a nearly 45% collapse. The contract eventually recovered to trade near $2,157, but the brief liquidity vacuum triggered cascading liquidations across the decentralized trading platform's order books."

"The sharp drawdown wiped out 1,393 leveraged positions across 405 individual users, resulting in a total notional loss of exactly $1.51 million. Market analysts noted that the median margin of the liquidated positions was only $31, indicating that the market was heavily skewed toward high- leverage retail participants."

"The SPACEX-USDH contract behaves as a synthetic perpetual tied to the implied market valuation of the aerospace company SpaceX. Because SpaceX remains a private entity with an initial public offering expected around June 11, there is no publicly available price benchmark for the asset. The market was built using Hyperliquid's HIP-3 architecture by a venue called Ventuals, which allows independent builders to construct pre-markets for private equities using the exchange's core matching engine."
