Who Pulled the Strings in Terra’s 40 Billion Crypto Meltdown?

Federal Lawsuit Alleges Jane Street Exploited Insider Knowledge to Crash Terra’s UST, Triggering $40B Collapse

A federal lawsuit filed on February 23, 2026, claims quantitative trading firm Jane Street used insider information to accelerate Terra’s UST stablecoin collapse, fueling a $40 billion market crash. 

The Manhattan federal complaint (Case No. 1:26-cv-1504) alleges Jane Street obtained confidential details of Terraform’s emergency measures via employees Bryce Pratt, Michael Huang, and co-founder Robert Granieri.

Well, the lawsuit targets events on May 8, 2022, when Terraform quietly withdrew ~150 million UST from Curve’s 3pool, the main liquidity hub for UST, USDC, USDT, and DAI, in a move meant to defend UST’s $1 peg. 

Minutes later, a wallet linked to Jane Street allegedly sold 85 million UST, the largest single sale in the pool’s history. The filing claims this coordinated action, with prior knowledge of the liquidity removal, triggered UST’s depegging and LUNA’s hyperinflation, wiping out both tokens. 

Around 4,400 retail investors in the Discord UST Restitution Group  had earlier sought accountability from Terraform Labs’ embattled CEO.

Lawsuit Alleges Jane Street Colluded with Terraform Labs in Controversial Crypto Trades

Allegations suggest Jane Street executives colluded with Terraform founder Do Kwon, discussing $200–$500M bailouts in discounted LUNA or Bitcoin. 

The complaint claims these talks gave Jane Street sensitive information used to front-run the market, potentially violating securities and commodities laws. 

Previously, Plaintiffs sought disgorgement, damages, and a jury trial, as the Federal Reserve warned of stablecoin vulnerabilities amid UST’s ongoing depeg.

Jane Street has firmly denied the allegations, calling the lawsuit “a desperate attempt by a bankrupt entity to extract money through baseless claims,” and stressing that all trades were legitimate and talks with Terraform were exploratory and non-binding.

Coming after similar cases like Jump Trading in 2025, this lawsuit revives debates from the 2022 “crypto winter,” which saw collapses including Three Arrows Capital and FTX. 

For investors holding LUNA Classic (LUNC) or tracking crypto recoveries, the case could signal potential windfalls, or further turmoil in crypto accountability.

As of February 24, 2026, proceedings are in their early stages with no immediate rulings expected. Jane Street’s deletion of all posts on X has added fuel to market speculation. 

This development comes even as reports emerge of suspected insider traders making over $1 million in the Axiom probe.

Conclusion

The Jane Street lawsuit highlights the clash between innovation and accountability in crypto. Its outcome could set a landmark precedent for insider trading, fiduciary duties, and transparency in decentralized markets. 

Investors, regulators, and enthusiasts are watching closely, as the case may reshape expectations of ethics in digital assets and influence recoveries for LUNA Classic holders. Terra’s collapse continues to reverberate, and the fight for accountability is far from over.
