Newly unsealed court filings in the Jane Street–Terraform insider trading case reveal that traders at the Wall Street giant allegedly joked internally about their “informational advantage” before dumping $192 million of TerraUSD—then panicked about being identified on-chain after the trade.
The amended complaint, filed last week in Manhattan federal court with fewer redactions than the original February filing, adds significant new color to a case since the initial lawsuit landed in February 2026. The new details center on internal communications, post-trade operational security concerns, and a previously undisclosed job offer that the estate’s administrator frames as part of a broader pattern.
“Slightly Pleased” About an Edge
The amended filing reveals the tone inside Jane Street as the Terraform relationship developed. In one internal exchange cited in the complaint, Bryce Pratt — the former Terraform intern who had joined Jane Street in September 2021 and established the private “Bryce’s Secret” Telegram channel with his former Terraform colleagues — is alleged to have joked that colleagues should be “slightly pleased” about having an “informational advantage.”
The framing matters legally. The estate’s administrator, Todd Snyder, is arguing that Jane Street did not merely benefit from better analysis or faster execution—standard advantages in quantitative trading—but from material non-public information obtained through a former insider who maintained active communication channels with Terraform’s engineering and business development teams.
Pratt had set up the “Bryce’s Secret” group chat by February 2022. The channel included Terraform’s head of business development and a senior software engineer. The amended complaint now includes the “informational advantage” language as direct evidence that Jane Street’s trading desk understood the nature of what they were receiving.
The $192M Dump and the Nine-Minute Window
The core allegation remains unchanged but is now more precisely documented. On May 7, 2022, at 5:44 PM Eastern Time, Terraform Labs quietly withdrew 150 million UST from the Curve 3pool. Less than nine minutes later, a wallet the complaint now identifies as Jane Street’s removed 85 million UST from the same pool—the single largest individual trade in the sequence that pushed UST off its dollar peg.
In total, Jane Street exited approximately 192 million UST tokens near par value. It then built short positions as the algorithmic stablecoin collapsed, generating roughly $134 million in profit as Terra’s $40 billion ecosystem unraveled over the following days.
Public post-mortems of the Terra collapse had long focused on that large Curve swap as a trigger event. The lawsuit now alleges the wallet belonged to Jane Street—transforming what was previously an anonymous on-chain event into a named actor with alleged insider access.
“Decommission” the Wallets
The most revealing new detail concerns what happened after the trade.
According to the amended complaint, a crypto analytics firm subsequently contacted a Jane Street associate and told them the firm had “made a killing” on the Terra collapse. Internal communications cited in the filing show Jane Street traders growing alarmed — not about the trade itself, but about how their wallets had been identified on-chain.
The traders then discussed how to “decommission” the wallets—a term that in practice means abandoning addresses that have been linked to a specific entity, replacing them with new addresses to restore operational anonymity.
The estate argues this reaction is consistent with consciousness of guilt: traders who believed their trades were legitimate would have had no reason to panic about wallet identification or to destroy the trail.
The Job Offer: Five Days After UST Hit Bottom
The amended complaint introduces a previously undisclosed detail: on May 18, 2022 — five days after UST reached its lowest point — Jane Street offered Terraform’s head of research a job. He started two weeks later.
The timing is significant in the estate’s narrative. Snyder frames the hire as part of a pattern in which Jane Street cultivated access to Terraform insiders—first through Pratt’s internship and subsequent Telegram channel and then by recruiting a senior researcher from the collapsing company while the wreckage was still fresh.
Jane Street has not publicly commented on the job offer allegation.
Jane Street’s Defense Holds
Jane Street has consistently denied all allegations. In its April 23 motion to dismiss, the firm argued the complaint is a “transparent attempt to extract money” and that losses were caused by Do Kwon’s “multi-billion dollar fraud,” not Jane Street’s trading. The firm invoked the Wagoner Rule, which generally bars a bankruptcy estate from suing third parties for harms caused by the debtor’s own management.
The motion to dismiss remains pending before the court. The estate’s opposition brief has not yet been filed.
Strengthened Legal Footing
The amended complaint now explicitly invokes both federal securities laws and the Commodity Exchange Act—a dual-track approach that broadens the potential liability. The securities claim is bolstered by a December 2023 federal court ruling in the SEC’s separate case against Terraform that found UST and Luna qualified as securities.
The Commodity Exchange Act claim adds a parallel theory: that Jane Street’s trading constituted manipulation or fraud in connection with commodity transactions. If UST is treated as both a security and a commodity (which different courts have found in different contexts), the estate can pursue claims under both statutory frameworks.
The case sits alongside a parallel $4 billion action against Jump Trading, filed by Snyder in December 2025, which alleges Jump secretly propped up UST before withdrawing support. Together, the two lawsuits represent the most aggressive legal effort to hold institutional trading firms accountable for their roles in the Terra collapse — an event that erased $40 billion in value, triggered a cascading contagion across the crypto industry, and contributed to the collapse of Three Arrows Capital, Voyager Digital, Celsius, and ultimately FTX.
