Jane Street Sued for Insider Trading Over Terraform Collapse

On Feb. 24, 2026, the court-appointed administrator winding down the affairs of Terraform Labs filed a civil lawsuit in federal court in Manhattan alleging that the prominent quantitative trading firm Jane Street Group engaged in insider trading and market-rigging that not only profited the firm but also helped accelerate the 2022 collapse of Terraform’s crypto ecosystem.

The complaint, filed by Todd Snyder, the bankruptcy administrator tasked with maximising recoveries for creditors of the defunct blockchain company, names Jane Street as well as several of its current and former employees — including co-founder Robert Granieri and traders Bryce Pratt and Michael Huang — for allegedly misusing material non-public information obtained from insiders at Terraform.

According to the heavily redacted complaint, Jane Street used privileged access to confidential data about Terraform’s liquidity decisions to conduct “front-running trades” that allowed it to reduce its exposure and realise profits just hours before the catastrophic collapse of TerraUSD (UST) and Terra (LUNA) in May 2022. The implosion of Terra’s algorithmic stablecoin wiped out roughly $40 billion in market value and sent shockwaves throughout the cryptocurrency industry, contributing to the downfall of major entities and raising scrutiny on algorithmic stablecoins.

Allegations of Insider Access and Timing

The suit claims that Jane Street gained a competitive edge through connections with individuals inside Terraform Labs, most notably a former intern, Pratt, who re-established communication with his old colleagues in early 2022. These interactions allegedly enabled Jane Street to access material nonpublic information about Terraform’s internal decisions moments before those actions became public — including significant liquidity movements tied to the UST token.

One specific incident cited in the complaint occurred on May 7 2022, when Terraform withdrew 150 million TerraUSD from a decentralized liquidity pool at Curve — information that was not publicly disclosed in real time. Within about 10 minutes, the lawsuit alleges, a wallet linked to Jane Street executed a separate withdrawal of 85 million TerraUSD from the same pool — the largest such swap by the firm at that time. Snyder’s complaint contends that this “front-running” transaction and others like it allowed Jane Street to unwind hundreds of millions of dollars in potential losses at precisely the moment when the Terra ecosystem was beginning to unravel.

The suit asserts that these trades not only protected Jane Street’s positions but also intensified selling pressure and market instability, contributing to the vicious downward spiral that ultimately destroyed the pegged value of the stablecoin, caused the collapse of its sister token LUNA, and inflicted heavy losses on retail and institutional investors alike.

Legal Context and Broader Implications

Terraform’s bankruptcy in early 2024 came after months of failed rescue attempts following the 2022 meltdown. The company’s founder, Do Kwon, was later extradited to the U.S., pleaded guilty to fraud charges, and was sentenced to 15 years in prison — a punishment reflecting what U.S. authorities described as a sprawling and deceptive fraud involving billions of dollars of investor funds.

The lawsuit against Jane Street is part of a broader effort by the bankruptcy administrator to pursue parties that may have profited from the collapse at the expense of Terraform’s creditors and the broader market. In late 2025, Snyder filed a similar lawsuit against Jump Trading, another high-frequency trading firm, accusing it of market manipulation and seeking roughly $4 billion in damages tied to its conduct surrounding the Terra collapse.

Legal analysts say the Jane Street case could have far-reaching implications for how legal liability is defined in digital asset markets, particularly where informal or private communication channels are used to transmit sensitive data. If the administrator’s claims are upheld, the litigation could establish precedents for the application of insider trading laws — long a cornerstone of traditional securities enforcement — to decentralized finance (DeFi) and crypto markets, where information flows are often more opaque.

Jane Street’s Response

Jane Street has publicly denied the allegations. In statements to media outlets, the firm described the lawsuit as a “baseless, opportunistic claim” and a “transparent attempt to extract money,” contending that the collapse of Terraform was the result of well-documented fraudulent conduct by the company’s management and not due to Jane Street’s trading activities. The firm says it intends to “vigorously defend” itself against the accusations.

Potential Stakes for Creditors and Regulators

For creditors of the now-defunct Terraform Labs, the outcome of this lawsuit could materially affect the size of the recovery they might eventually receive. Litigation proceeds — whether through settlement or judgment — would be added to the asset pool available to satisfy claims in the bankruptcy proceedings. Beyond financial ramifications, the case is expected to be closely watched by regulators and market participants as a measure of how legal systems interpret trading conduct in the increasingly complex world of tokenized assets, automated trading strategies, and decentralized networks.

As the case moves forward in the U.S. District Court for the Southern District of New York, all parties — from Jane Street to Terraform’s winding-down trust — will likely marshal extensive legal and financial evidence. The complexity of blockchain markets, the novelty of crypto asset trading practices, and questions of information asymmetry could make this a landmark case in the intersection of finance, technology, and law.
