Terraform Trustee Sues Jump Trading for $4B Over TerraUSD (UST) Collapse

The court-appointed bankruptcy trustee for Terraform Labs has filed a $4 billion lawsuit against market-maker Jump Trading, alleging undisclosed liquidity deals and coordinated trades that propped up the algorithmic stablecoin TerraUSD (UST) and allowed Jump to profit from discounted LUNA allocations. The complaint, brought by trustee Todd Snyder, says agreements with Jump began as early as 2019, included purchases of LUNA at steep discounts, and featured a “gentlemen’s agreement” under which Jump bought UST during stress events (notably the May 2021 UST depeg) to restore the peg while Terraform publicly credited its algorithm. The trustee alleges later contract revisions removed vesting and lockups for Jump, enabling immediate sales of monthly LUNA allocations and increasing sell pressure as systemic risk rose. Jump denies wrongdoing and intends to defend itself; it previously resolved SEC charges via its crypto arm Tai Mo Shan for about $123 million without admitting fault. The suit seeks damages and disgorgement for claims such as fraud, aiding and abetting, and unjust enrichment, and aims to hold third parties accountable beyond founder Do Kwon. Traders should watch for heightened regulatory scrutiny of market makers and liquidity providers, possible large recoveries or settlements that could trigger asset movements, and renewed legal pressure on off‑book liquidity arrangements supporting algorithmic stablecoins.
