In May 2022, the crypto world witnessed one of the most catastrophic collapses in its history. UST, once hailed as the model for algorithmic stablecoins, lost its peg. In just a few days, over $40 billion in market value evaporated, and the LUNA price plunged from its peak to nearly zero.

Nearly four years later, a complaint filed in Manhattan federal court has given this story a new twist. The bankruptcy liquidator for Terraform Labs alleges that Jane Street, one of the world’s most secretive and profitable quantitative trading firms, may have been the party that knew the outcome in advance.
Jane Street and "Bryce’s Secret"
To understand the core of these allegations, you need to know about a private group chat called "Bryce’s Secret." According to the lawsuit, Jane Street employee Bryce Pratt was previously an intern at Terraform. Early in 2022, he created a private channel connecting the two companies. The complaint alleges that through this hidden information pipeline, Jane Street learned ahead of time about Terraform’s critical yet undisclosed decision to quietly withdraw liquidity from the Curve pool.
Let’s rewind to May 7, 2022, at 5:44 PM. Just ten minutes after Terraform Labs quietly withdrew 150 million UST from Curve’s 3pool, a wallet allegedly linked to Jane Street followed suit, pulling 85 million UST from the same pool. This was the largest single transaction ever recorded in the pool’s history.
According to the liquidator, Jane Street’s alleged insider trading allowed it to "close out hundreds of millions of dollars in potential risk exposure at precisely the right moment, just hours before the collapse of the Terraform ecosystem." This massive withdrawal ahead of the market crash intensified panic and is seen as a key driver accelerating UST’s depegging and LUNA’s death spiral.
The Double Role of a Quantitative Giant
Jane Street, one of the world’s largest quantitative trading firms, manages hundreds of billions in assets and plays a pivotal role as a market maker in both traditional finance and crypto markets. Its alumni list includes FTX founder SBF, giving it indirect ties to several major crises in the crypto industry.
However, this lawsuit from Terraform marks the first time these "connections" have been directly linked to alleged illegal insider trading. Jane Street’s response has been unequivocal. A spokesperson called the lawsuit "a desperate action" and "a transparent attempt to extract money from the company." The firm insists that the losses suffered by Luna holders stem from "multi-billion dollar fraud orchestrated by Do Kwon and Terraform’s management."
Deeper Shadows and Industry Reflection
Jane Street’s case is not an isolated incident. Two months ago, the same liquidator filed a $4 billion claim against another trading giant, Jump Trading, in Chicago federal court, accusing it of playing an unsavory role in the Luna collapse.
Together, these lawsuits paint a troubling picture of the industry: beneath the crypto market’s claims of "decentralization" and "transparency," information asymmetry persists. When retail investors’ funds vanish in a death spiral, did institutions with privileged information and advanced trading tools already exit safely—and even profit?
Conclusion
Currently, the allegations against Jane Street remain in litigation, and the court has not issued any rulings. Jane Street firmly denies any wrongdoing and is prepared to defend itself vigorously. Regardless of the final verdict, this case forces the market to reconsider the boundaries of responsibility for market makers in the crypto ecosystem.
As for the question, "Should they be held responsible for one of the biggest collapses in crypto history, LUNA?"—the legal answer may take time, but the debate over market fairness is once again front and center.
