Jane Street Hit With Third Lawsuit Over 2022 Terra-Luna Crash, Facing Insider Trading Allegations

Financial heavy-hitter Jane Street Group, one of Wall Street’s most influential quantitative trading firms, is facing a third lawsuit linked to the 2022 collapse of the Terra ecosystem — a meltdown that wiped out roughly $40 billion in market value and remains one of the most consequential failures in crypto history. The legal action, filed in Manhattan federal court, casts new legal scrutiny on how institutional players interact with high-risk crypto protocols. 

The lawsuit was brought by Todd Snyder, the court-appointed bankruptcy administrator winding down TerraForm Labs— the company behind TerraUSD (UST) and its sister token LUNA. The complaint alleges that Jane Street and several named employees, including co-founder Robert Granieri and traders Bryce Pratt and Michael Huang, engaged in insider trading and market manipulation by using confidential, non-public information to place trades ahead of the market during the critical days leading up to Terra’s collapse. 

Allegations of Insider Trading and Front-Running

At the core of the lawsuit is a sequence of events in May 2022 when Terra’s algorithmic stablecoin, UST, began losing its dollar peg. According to the complaint, Terraform Labs made a large, undisclosed liquidity withdrawal — removing 150 million UST from a Curve Finance liquidity pool. Minutes later, a wallet allegedly linked to Jane Street withdrew 85 million UST from the same pool, in what the complaint claims was a perfectly timed move that could not have occurred without access to confidential information. This, the filing asserts, allowed Jane Street to minimize losses and profit while other market participants were blindsided by the deteriorating situation. 

The lawsuit points to alleged insider communications facilitated through an internal group chat dubbed “Bryce’s Secret”, where former Terraform Labs personnel and Jane Street traders reportedly exchanged sensitive details about the protocol’s plans and liquidity decisions — information that was not yet public. 

Broader Legal Context & Industry Impact

The latest filing follows earlier legal actions — including a separate lawsuit against Jump Trading in late 2025 that accused the firm of secretive dealings around Terra as well. With multiple cases now tying major trading firms to the Terra collapse, the litigation highlights broader institutional accountability debates in the crypto sector and raises questions about how market makers with privileged access can influence decentralized ecosystems. 

Industry observers note that the allegations extend beyond smart contract flaws; they suggest that private channels and insider access in crypto — often criticized as transparent on-chain but opaque off-chain — may have materially impacted outcomes for retail investors. The Terra meltdown triggered a systemic downturn across digital assets at the time, with ripple effects lasting years, and this lawsuit could reshape how regulators and courts view information asymmetry in crypto markets. 

Jane Street’s Response

Jane Street has vigorously denied the claims, characterizing the lawsuit as an opportunistic attempt to extract money from a firm that, in its words, “suffered substantial losses due to multibillion-dollar fraud perpetrated by Terra’s own management.” The firm says it will defend itself aggressively and rejects the notion that its trades caused or accelerated the collapse. 

What’s Next

With this being the third major suit tied to Terra’s collapse and insiders now implicated, the crypto community and legal observers will be watching closely as discovery and court proceedings unfold. The case could set new precedents for how insider trading and market manipulation laws apply to crypto markets — especially when algorithmic protocols and institutional players intersect.
