In a Manhattan federal court filing, trading powerhouse Jane Street has requested the dismissal of a lawsuit brought by Terraform Labs’ bankruptcy estate. The legal action alleged that Jane Street engaged in insider trading that exacerbated the 2022 Terra ecosystem meltdown.

Todd Snyder, the court-designated administrator for Terraform, initiated the lawsuit this past February. The complaint targeted Jane Street, its co-founder Robert Granieri, along with staff members Bryce Pratt and Michael Huang. The defendants faced accusations of executing Terra token transactions based on confidential information obtained from sources within Terraform.

In its dismissal motion, Jane Street responded forcefully. The company characterized the legal action as a scheme “to extract cash from Jane Street to foot the bill for a fraud that Terraform itself perpetrated on the market.”

The Terra network experienced a catastrophic failure in May 2022. TerraUSD, its algorithmic stablecoin, rapidly lost its one-dollar peg. The resulting panic triggered a LUNA token crash that eliminated approximately $40 billion in market capitalization.

Prior Legal Proceedings Already Addressed the Fraud

Jane Street’s central contention is that courts have already adjudicated the underlying fraudulent conduct. In December, Terraform founder Do Kwon entered a guilty plea to charges of conspiracy and wire fraud. He is currently incarcerated, serving his 15-year sentence.

Additionally, a jury determined that Terraform and Kwon bore civil liability for securities fraud. Kwon personally acknowledged being “alone responsible for everyone’s pain,” as referenced in the court documents.

Jane Street maintains it played no role in Terraform’s fraudulent operations and argues that using this lawsuit to relitigate what caused the collapse is legally inappropriate.

The company also invoked the “Wagoner rule,” a legal doctrine preventing bankruptcy estates from pursuing third-party defendants to recoup damages stemming from the estate’s own fraudulent behavior.

Insider Trading Allegations Labeled “Self-Defeating”

Jane Street mounted a direct challenge to the insider trading accusations. The firm highlighted that its most substantial TerraUSD transaction took place just 10 minutes after the allegedly confidential information appeared in the public market.

According to the filing, Terraform accused Jane Street of obtaining advantages through “back-channel communications” regarding when a liquidity pool transition would occur. However, Jane Street asserts that Terraform couldn’t pinpoint even one specific communication, despite comprehensive pre-litigation discovery efforts.

Jane Street further emphasized that Terraform had publicly announced the liquidity pool transition several weeks before any relevant trading activity, and that this announcement generated no observable market response when initially disclosed.

The company established a short position starting May 8, 2022, and executed asset sales on May 7. Jane Street maintains that Terraform has failed to identify any information that qualified as both material and nonpublic during those trading periods.

Jane Street additionally presented a jurisdictional challenge, contending that Terraform has not demonstrated that the disputed transactions occurred within United States territory.

The firm requests the court grant dismissal with prejudice, a ruling that would permanently bar Terraform’s estate from pursuing identical claims in the future.
