Hyperliquid's pre-IPO SpaceX contracts suffers 45% flash crash, liquidating $1.5 million

A massive selloff in a SpaceX crypto token wiped out hundreds of retail traders in 30 minutes because the market lacked enough cash to absorb the shock.

What to know:

• A violent 45% flash crash wiped out hundreds of retail traders when a SpaceX-linked crypto contract plummeted in just 30 minutes, wiping out $1.51 million in value and catching small-time investors completely off guard.
• The market was too thin to handle one massive trade because the token lacked deep financial backing, meaning a single giant sell order absorbed the market's available cash and sent the price into a temporary freefall.
• High risks face everyday investors ahead of a potential IPO as the crash heavily burned retail traders using leverage on a highly speculative token that has no official public price benchmark.

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.

The Hyperliquid SPACEX-USDH is a crypto perpetual contract for SpaceX's market valuation. As the company is private, people cannot buy its stock ahead of its anticipated IPO. To get around this, Hyperliquid created a synthetic perpetual contract that allows investors to bet on what they think the company will be worth.

Traders aren't buying actual shares of Elon Musk's rocket company, nor do they get any ownership or shareholder rights.

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.
