30-minute flash crash of 45%, SpaceX hasn't even gone public yet and retail investors have already taken a hit

Original Author: ChandlerZ, Foresight News

On the evening of May 28, the SPACEX-USDH perpetual contract on Hyperliquid experienced a severe flash crash, with the price dropping from $2,277 to a low of $1,254 within 30 minutes, a decline of nearly 45%, before rebounding to approximately $2,169.

This crash led to the liquidation of 405 users and 1,393 positions, with total liquidations amounting to $1.51 million.

Data shows that the total trading volume of this contract over the past 24 hours was only about $4.87 million, with open interest below $2.9 million, indicating extremely low market depth. A single large sell order nearly pierced through the liquidity, triggering a cascading sell-off. Users who were liquidated were primarily retail investors, with a median margin of only about $31, typically using around 3x leverage.

Ventuals, a perpetual contract platform within the Hyperliquid ecosystem, responded on Twitter after the incident, stating that the team had noted the flash crash in the SPACEX market. The cause was erroneous data returned by an off-chain data provider, one of the components of the oracle price, leading to drastic fluctuations in the oracle price and mark price of this market, consequently triggering forced liquidations of some user positions.

The team has since taken measures to prevent similar incidents from recurring. Furthermore, the team is assessing the impact of this event on affected users to formulate an appropriate compensation plan. Affected users will receive compensation within the next 48 hours.

A Fragile Pricing Chain

SPACEX-USDH is a crypto perpetual contract launched by Hyperliquid that allows users to bet on changes in SpaceX's market valuation before its IPO. It does not represent actual stock nor confer any shareholder rights.

On Ventuals, 1 SPACEX represents a $1 billion valuation of SpaceX. If the SPACEX price is $420.69, it implies the market's valuation of SpaceX is $420.69 billion.

The core challenge for such contracts is: how does one price a company that is not publicly traded?

Ventuals' solution is to split the pricing into two parts. One-third of the weight comes from off-chain private market data provider Notice, whose pricing model incorporates funding rounds, 409A valuations, mutual fund marks, secondary market trades and quotes, and comparable publicly listed companies.

Two-thirds of the weight comes from the exponentially weighted moving average of the contract's own mark price over the past 2 hours. Notice data is polled at least once per minute, and the oracle price is updated every 3 seconds.

In an ideal state, this design can balance external information with on-chain price discovery. However, it has a fatal single point of failure. If the data returned by Notice is itself erroneous, the one-third external anchor becomes a force pulling the price in the wrong direction.

The remaining two-thirds on-chain average price could hedge against this error under ample liquidity. But on the SPACEX contract, with a daily trading volume of just $4.87 million, the on-chain price itself is fragile. When two fragile components are combined, the result is a price flash crash.

Low Liquidity Under Zero Arbitrage and Fragmentation

The SPACEX flash crash exposes a problem not unique to Ventuals. The entire category of pre-IPO synthetic products faces the same dilemma regarding pricing mechanisms: the absence of a unified spot market and a lack of cross-platform arbitrage channels.

In traditional finance, price discrepancies for the same stock listed on the NYSE and Nasdaq are almost non-existent due to high-frequency market makers executing arbitrage in milliseconds. However, in the market for pre-IPO synthetic products, this type of arbitrage is structurally impossible. This is because the contracts on each platform are assets or derivatives issued according to their own rules, making cross-platform hedging impossible.

The SPACEX contract on Hyperliquid and the SPCX contract on Binance track the same company, but there is no mechanism to ensure their prices are consistent. Consequently, each platform forms its own closed pricing pond. Liquidity is dispersed across multiple, non-interconnected venues, making each pond shallower than the whole.

Ventuals' SPACEX has a daily volume of $4.87 million. If the liquidity from existing platforms were concentrated in one place, the depth would be completely different. However, fragmentation leaves each platform exposed to the risk of low liquidity.

The essence of pre-IPO synthetic products is a group of people betting against each other on a number without a public price benchmark. The price discovery on each platform only reflects the consensus of the small group of traders on that platform, with no rigid connection to the company's actual valuation.

Data sources like Notice provide private market information, characterized by low update frequency, narrow coverage, and opacity. No one truly knows what SpaceX is worth. The valuation distribution for the SpaceX IPO on Polymarket is similarly fragmented, with a 45% probability for the range exceeding $2.4 trillion and a 31% probability for the range exceeding $2.6 trillion.

The Answer is Imminent

SpaceX submitted a confidential S-1 filing to the SEC on April 1, targeting a pricing date of June 11 on the Nasdaq, with trading commencing June 12. The valuation range is estimated between $1.75 trillion and $2 trillion.

Ventuals' documentation outlines the contract's settlement mechanism. On the first day of the IPO after market open, the funding rate resets to zero, the oracle price locks to the mark price, and a valuation based on the real-time stock price is introduced as an external price constraint. After market close, the mark price is overwritten by the valuation based on the closing price, and all open positions are forcibly settled at this price.

This means that on the IPO day, all holders of SPACEX contracts will be settled based on the actual stock price. If there is a significant gap between the on-chain price and the Nasdaq price, the settlement moment will be a massive one-way liquidation.

Analysts estimate the current gap is around 60%, and convergence will likely not be smooth. This is because there is no way to hedge on-chain positions with actual SpaceX stock before the IPO; the arbitrage mechanism is structurally broken. Convergence will likely occur violently within the final 72 hours.

This flash crash was triggered by an oracle data error. However, the convergence on the IPO day in June will be driven by the calibration to the real price. The extent of its impact will depend on the total open interest across multiple platforms at that time. The closer SpaceX gets to its IPO, the more speculative capital will flow in, simultaneously inflating both fragmented liquidity and distorted pricing.

The user demographic with a median margin of $31 will not disappear. They will return, with more $31 margins.
