Trade.xyz, the operator of onchain perpetual markets on Hyperliquid, said it will reimburse eligible liquidation losses tied to a sudden mark-price move in its SK Hynix contract. The platform described the payout as a one-time discretionary decision following an external price print that fed into its oracle.

At 23:01 UTC on July 27, the SKHYNIX mark price fell from $1,127.90 to $917.25, an 18.7% decline. The move forced liquidations of leveraged long positions. Estimates of the total liquidated value range from roughly $57 million affecting about 960 accounts to more than $80 million, though Trade.xyz has not confirmed a final figure.

Origin of the Price Move

The drop originated from a single executed trade on South Korea’s NextTrade pre-market venue. One SK Hynix share changed hands at 1.272 million won, 29.96% below the prior close of 1.816 million won and at the daily lower price limit. Thin liquidity at the open allowed that isolated print to set the reference price. Within about two minutes, buy orders arrived and the stock recovered toward the 1.7 million won range.

Multiple independent data providers relayed the executed trade. Trade.xyz’s oracle, which tracks the primary South Korean pre-market source and converts the Korean won price into a US-dollar mark for the perpetual, incorporated the print according to its published specification. The platform stated that the oracle operated as designed and that no system malfunction or market manipulation has been identified.

Hyperliquid uses the mark price to value positions for margin and to determine liquidations. Because the anomalous external print became the reference, leveraged long positions were closed even though the move did not originate on Trade.xyz’s own order book. The underlying stock later closed the regular Seoul session at 1.55 million won, down 14.65%, a steep but verified decline that remained well above the isolated pre-market print.

Market Context and Contract Activity

The SK Hynix perpetual ranks among the most active contracts on the platform. Hyperliquid data showed more than $1.5 billion in 24-hour volume and open interest near $600 million around the time of the incident. Cumulative volume on the contract has exceeded $20 billion. The market operates under Hyperliquid’s HIP-3 framework, under which external builders supply market-specific oracle and mark-price inputs while Hyperliquid provides the order book, margin and liquidation infrastructure.

Trade.xyz has accounted for the large majority of early HIP-3 volume. The platform noted that its own order books now carry deeper liquidity and more useful price signals than some external venues.

Reimbursement Plans and Future Adjustments

Trade.xyz said it will cover liquidation losses attributable to the anomaly. Eligibility criteria have not yet been published. The platform stated that requirements will be released soon and that distributions are expected within days. It has not disclosed the total reimbursement amount, the precise formula, whether payments will be automatic or claim-based, or how partial liquidations will be treated.

The company described the reimbursement as a discretionary, one-time response rather than a standing commitment for future events. It is accelerating a review of how external venue prices enter its system and plans to assign greater weight to prices formed on its internal order books during extreme conditions.

NextTrade is separately preparing a static volatility interruption safeguard scheduled for September that would switch trading to a two-minute call auction after sharp moves. Trade.xyz has not yet issued a detailed incident report or final eligibility notice.

SK Hynix later released second-quarter results showing a large rise in profit that nevertheless missed estimates, contributing to further declines in the underlying shares. The pre-market anomaly occurred hours before a broader slide in Korean equities.
