Jane Street is facing a lawsuit that could become one of the most consequential legal cases in crypto history. Terra filed the complaint in February 2026, alleging the trading firm used non-public information to profit from the UST and LUNA collapse. The allegations are serious, the stakes are high, and the crypto industry is paying close attention.
What Terra Is Claiming Happened
The complaint says Jane Street got access to sensitive information about the Terra ecosystem that regular traders simply didn’t have. Then allegedly used it. Positioned themselves. And walked away okay, while everyone else got destroyed.
Cast your mind back to May 2022 for a second. UST was meant to hold $1. That was the whole pitch. LUNA was what kept the peg alive. When UST started slipping, it didn’t just slide; it cratered. LUNA went from around $80 to basically nothing in days. Not weeks. Days.
People lost everything. Not “lost some gains,” everything. Actual savings. People in Seoul, in Lagos, in Manchester had been holding this stuff. Forums were full of it at the time, people posting that they’d put in money they couldn’t afford to lose.

Total losses from the UST-LUNA collapse were estimated at around $40 billion, according to reporting from CoinDesk and Bloomberg at the time.
Terra’s lawsuit is now saying Jane Street saw some version of this coming. That the firm had information others didn’t. Whether that’s provable is a whole different question, but that’s the allegation sitting in the filing.
Why Jane Street’s Position in Markets Makes This Particularly Significant
Market Makers See Things Others Don’t
Firms like Jane Street don’t operate like regular traders. They act as market makers, sitting at the center of trading activity, providing liquidity, and keeping markets moving. That role hands them a view into order flow and market dynamics that most participants never get near.
It’s a privileged seat. And Terra’s lawsuit argues that Jane Street used that seat in a way that crossed a clear line. That instead of supporting the market, the firm allegedly exploited its access when it mattered most.
If that gets proven, every major market maker active in crypto right now should be uncomfortable.

Retail Investors Are the Ones Who Paid
Insider trading isn’t abstract. Every time an institution trades on information the public doesn’t have, someone on the other side of that trade absorbs the loss. In this case, those people were retail holders across multiple continents who had no idea what was about to happen to their portfolios.
That human cost is part of why this lawsuit carries weight beyond just the legal proceedings.
What Regulators Could Do Next
The timing here is worth noting. The EU’s MiCA framework is already in effect. US crypto legislation is still being debated. Cases like this have historically pushed those conversations forward faster than lobbying ever does.
What regulators may start examining more seriously includes how trading firms access information from token issuers, what disclosure obligations should exist before major institutional trades, and whether market maker agreements in crypto need proper oversight frameworks.
The SEC charged a former Coinbase employee with insider trading back in 2022. That case was relatively contained. A lawsuit involving Jane Street and a $40 billion collapse operates at a completely different scale.

What Jane Street Has Said
At the time of writing, Jane Street has not issued a detailed public response to Terra’s allegations. The case remains in its early stages. No verdict or settlement has been reached.
So Is Crypto Actually Being Manipulated?
Crypto sold itself on being different. No middlemen running the show behind closed doors. No institutional players with better data than you. That was the pitch anyway. What’s actually happened is that the same institutional infrastructure followed the money in and brought its habits with it.
The Terra case is asking whether the rules actually apply when one of those institutions is Jane Street.
What is this lawsuit actually claiming?
Terra filed against Jane Street in February 2026, alleging the firm traded UST and LUNA using non-public information before the collapse. Terra says the firm profited while retail investors did not.
Has Jane Street said anything about it?
Nothing detailed and public as of writing. The case is still early. That silence isn’t unusual at this stage of litigation, but it hasn’t gone unnoticed.
Could regular crypto investors be affected by how this plays out?
Potentially yes. If Terra wins or forces a settlement, it puts every major market maker on notice that crypto isn’t a consequence-free zone. That matters for market structure long term.
What happened to UST and LUNA in 2022?
UST lost its $1 peg and couldn’t recover. LUNA, which was designed to absorb the instability, hyperinflated into worthlessness. Around $40 billion in value was wiped out across both assets within days.
