Jane Street has asked a Manhattan federal court to throw out, with prejudice, the lawsuit accusing the trading firm of helping worsen the 2022 Terra collapse. The motion, filed on April 23, 2026, targets claims brought by the bankruptcy administrator winding down Terraform Labs. The filing matters because a dismissal with prejudice would block the same claims from being refiled, sharply narrowing one of the latest legal fronts tied to the implosion that erased roughly $40 billion in market value in May 2022.
Jane Street moves to end the case permanently
According to coverage published on April 24, 2026, Jane Street filed its motion to dismiss in the U.S. District Court for the Southern District of New York on Thursday, April 23, 2026. Cointelegraph reported that the firm asked the court to dismiss the complaint with prejudice, meaning Terraform’s estate would not be allowed to bring the same lawsuit again. Crypto Economy and TheStreet separately reported the same filing date and the same core request, which helps verify the procedural posture of the case across multiple outlets.
The lawsuit itself was filed in February 2026 by the administrator overseeing Terraform Labs’ wind-down. Reports from The Block, Law360, and other legal and crypto publications say the complaint accuses Jane Street of insider trading and market manipulation tied to TerraUSD, also known as UST, and LUNA before the ecosystem’s collapse in May 2022. The administrator alleges Jane Street used material nonpublic information connected to Terraform’s market-support arrangements and liquidity conditions.
Jane Street’s response is blunt. In the motion described by Cointelegraph and TheStreet, the firm argues the case is an attempt to shift blame for Terra’s failure away from Terraform itself. One quoted line from the motion says the suit seeks “to extract cash” from Jane Street for a fraud that Terraform allegedly inflicted on the market. That language is important because it signals Jane Street is not merely disputing details. It is attacking the legal theory and the factual premise of the complaint at the same time.
What the Terraform complaint alleges about the 2022 collapse
The underlying allegations focus on the days around Terra’s breakdown in May 2022, when UST lost its dollar peg and LUNA spiraled lower. Multiple reports on the February 2026 complaint say Terraform’s estate claims Jane Street had an informational edge regarding liquidity stress and trading conditions. The Block’s summary of the complaint points to one specific allegation: Terraform withdrew 150 million UST from Curve’s 3pool on May 7, 2022, without public disclosure. The complaint argues that nonpublic knowledge around such moves gave Jane Street an unfair advantage.
That 150 million UST figure has become one of the most cited details in the case because it gives the allegations a concrete event and date. The administrator also reportedly named Jane Street co-founder Robert Granieri and employees including Michael Huang and Bryce Pratt in the February complaint, according to DL News and other reports. The theory is that privileged access or continuing communications allowed Jane Street to position trades in a way that accelerated the depeg and deepened losses across the Terra ecosystem.
Terraform’s side is trying to connect those alleged trades to a collapse that destroyed tens of billions of dollars in value. Several reports, including TheStreet and BanklessTimes, place the investor wipeout at about $40 billion. That number has long been central to Terra-related litigation because it frames the scale of harm and the stakes for any party accused of contributing to the crash.
Why Jane Street says the claims should fail as a matter of law
Jane Street’s dismissal push appears designed to stop the case before discovery. That is a crucial point. If the court grants dismissal with prejudice, the estate loses not just this version of the complaint but the chance to revive the same claims in a new filing. For defendants, that is the cleanest possible early-stage win short of settlement or judgment after trial.
The firm’s argument, based on the reporting available so far, has two layers. First, it denies wrongdoing and rejects the accusation that it possessed or exploited inside information. Second, it argues Terraform itself caused the disaster through its own conduct. That second layer matters because it tries to break causation. Even if Jane Street traded aggressively, the firm appears to be saying, Terraform’s own design flaws and alleged fraud were the real drivers of the collapse.
That defense lands in a legal environment already shaped by earlier findings against Terraform and co-founder Do Kwon. In April 2024, a jury in the Southern District of New York found Terraform and Kwon liable in the SEC’s civil fraud case, a result reflected in widely reported case coverage and public SEC materials. The SEC had originally sued Terraform and Kwon in February 2023 and filed an amended complaint on April 3, 2023. Those earlier proceedings do not decide the Jane Street case, but they give Jane Street a ready-made narrative: Terraform is trying to redirect liability after already being found responsible for deceiving investors.
The bigger legal significance for Terra creditors and crypto litigation
The unique angle here is not simply that Jane Street wants the case dismissed. Nearly every defendant does. The more important point is what a with-prejudice dismissal would mean for Terraform’s bankruptcy estate. The estate is looking for recoveries that could potentially benefit creditors, and this lawsuit is one route to pursue money from a deep-pocketed trading firm. If the court shuts that route permanently, the estate’s leverage drops.
There is also a broader market-structure issue. The complaint tests how far courts are willing to entertain claims that sophisticated trading firms exploited informational asymmetries in crypto markets during periods of stress. Crypto markets in May 2022 were fragmented, lightly supervised compared with traditional markets, and heavily dependent on liquidity pools, market makers, and cross-venue flows. A ruling that trims or rejects these claims could make similar future suits harder to plead unless plaintiffs can show very specific evidence of nonpublic information, duty, reliance, and causation.
On the other hand, if the motion fails, the case could move into discovery, where internal communications, trading records, and deal terms might become central. That would be the stage where the complaint’s most serious allegations either gain traction or start to unravel. For now, though, the procedural fight is the story.
What happens next in the Manhattan court fight
The next step is the court’s review of Jane Street’s motion and any opposition filed by Terraform’s estate. No ruling was identified in the available April 24, 2026 coverage, so the case remains at the motion-to-dismiss stage. Because the filing was made in the Southern District of New York, a court that has already handled major Terraform-related litigation, the judge will be working against a well-developed factual and regulatory backdrop.
That backdrop includes the SEC’s long-running case, Terraform’s bankruptcy wind-down, and the continuing legal fallout from one of crypto’s most destructive failures. Terra’s collapse in May 2022 did not just wipe out UST and LUNA holders. It also triggered contagion across lenders, funds, and trading firms, making every later lawsuit part of a larger effort to assign responsibility for a systemic shock.
For readers tracking the case, the key phrase is still “with prejudice.” It is a procedural term, but it carries real weight. If Jane Street gets what it wants, this lawsuit does not just pause. It ends.
Frequently Asked Questions
What did Jane Street ask the court to do?
Jane Street asked the U.S. District Court for the Southern District of New York to dismiss the Terraform-related lawsuit with prejudice. That means the plaintiff would be barred from refiling the same claims if the court grants the request.
Who filed the lawsuit against Jane Street?
The lawsuit was filed in February 2026 by the bankruptcy administrator overseeing the wind-down of Terraform Labs. The complaint alleges insider trading and market manipulation tied to the 2022 Terra collapse.
What is the lawsuit about?
The case centers on allegations that Jane Street used material nonpublic information about Terraform’s liquidity conditions and market-support activity to trade UST and related assets in a way that worsened the collapse of the Terra ecosystem.
Why is “with prejudice” important?
A dismissal with prejudice is more final than an ordinary dismissal. It would prevent Terraform’s estate from bringing the same lawsuit again, which would be a major legal win for Jane Street.
How does this connect to Do Kwon and Terraform’s earlier legal troubles?
The dispute sits within the broader fallout from Terra’s May 2022 collapse. Terraform and Do Kwon were already found liable in the SEC’s civil fraud case in April 2024, and Jane Street is using that broader history to argue Terraform itself caused the damage.
What happens next?
The court will consider Jane Street’s motion and any response from Terraform’s estate. If the motion is denied, the case could proceed into discovery. If it is granted with prejudice, the lawsuit would effectively be over.
