Terra Trustee Sues Jane Street Over $192M UST Sale Ahead of Collapse

NEW YORK — The bankruptcy trustee for Terraform Labs has sued global quantitative trading firm Jane Street in Manhattan federal court, alleging the firm used non-public information to dump roughly $192 million of UST hours before the algorithmic stablecoin lost its dollar peg in May 2022.

Per the filing, Jane Street liquidated approximately 193 million UST on May 7, 2022, then took a short position the trustee says generated about $134 million in profit. The complaint claims the firm acted on insider knowledge that materially preceded the public unraveling of the Terra ecosystem.

The trustee said one trade of $85 million in UST was executed nine minutes after Terraform Labs withdrew $150 million in liquidity from a Curve Finance pool. The filing argues that withdrawal was an internal distress signal not visible to ordinary market participants.

The source of the alleged tip, according to the complaint, was a private Telegram channel called "Bryce's Secret." The trustee identified Bryce Pratt, a former Terraform Labs intern who was working at Jane Street at the time, as the conduit for information drawn from contacts inside the project.

Jane Street denied the allegations. In a statement, the firm attributed investor losses to what it described as a multi-billion dollar fraud by Terraform Labs management and said it would "vigorously defend" itself against the claims. The firm framed the lawsuit as an effort to redirect responsibility away from the project's founders.

The Terra collapse erased an estimated $40 billion in market capitalization across UST and the LUNA token in May 2022, one of the largest single-event losses in the history of digital assets. Multiple criminal and civil proceedings tied to the event remain active in the United States and South Korea.

The case is being filed under U.S. bankruptcy court jurisdiction tied to Terraform Labs' insolvency proceedings. The trustee is seeking recovery of the trading profits and damages on behalf of the bankruptcy estate. No trial date has been set.

The allegations are unproven. Jane Street has not been charged with any crime in connection with the trades, and the lawsuit is a civil action brought by the estate rather than a regulatory enforcement matter.

What it means: The complaint pushes a question regulators have skirted for three years — whether U.S. insider trading doctrine extends to non-securities digital assets traded across decentralized venues. A ruling against Jane Street, or even a substantive denial of its motion to dismiss, would give bankruptcy estates and class-action plaintiffs a template for clawing back trading gains from sophisticated firms operating in unregulated crypto markets. A win for Jane Street would reinforce the existing patchwork, in which information asymmetry around stablecoins and DeFi protocols remains largely outside federal market-abuse rules.
