The bankruptcy estate of Terraform Labs has filed a blockbuster $4 billion lawsuit against trading giant Jump Trading, accusing it of market manipulation that artificially prolonged the Terra ecosystem’s stability before its catastrophic 2022 collapse.
Filed on December 18, 2025, by plan administrator Todd Snyder in U.S. District Court, the complaint alleges Jump entered secret agreements with founder Do Kwon as early as 2019. These reportedly allowed Jump to buy massive LUNA quantities at steep discounts while posing as a neutral market maker.
Central to the claims: In May 2021, when algorithmic stablecoin TerraUSD (UST) briefly lost its $1 peg, Jump allegedly bought huge volumes off-chain to restore it—actions publicly attributed to Terra’s algorithm. This deception, the suit argues, fostered false confidence, drew in more investors, and delayed inevitable corrections.
When support ceased, UST’s 2022 depeg triggered a death spiral, hyperinflating LUNA and erasing ~$40 billion in value—sparking industry-wide contagion, bankruptcies, and a prolonged bear market.
The lawsuit claims Jump profited enormously (~$1 billion from prior estimates), including by lifting vesting restrictions for quick sales at peak prices. It seeks damages for manipulation, self-dealing, and misuse of assets to recover funds for creditors.
Jump Trading has faced prior Terra scrutiny, including a 2024 SEC settlement by a subsidiary over related misrepresentations. The firm has historically denied manipulation, framing activities as legitimate trading.
These remain allegations, with no court rulings yet. The case could expose internal dealings via discovery, intensifying debates on transparency, algorithmic stablecoins, and influential traders’ roles in crypto markets. As regulators heighten oversight post-Terra, the outcome may influence future rules on market-making and disclosure.
