Jane Street Sued for Insider Trading in Terra Collapse

The Terraform Labs bankruptcy estate filed a lawsuit in Manhattan federal court accusing Jane Street of using a secret Telegram channel to sell $192 million in UST before the stablecoin broke its peg, then shorting the ecosystem for $134 million in profits. The complaint, made public May 21, 2026, names the trading firm, co-founder Robert Granieri, and trader Michael Huang as defendants. Jane Street has moved to dismiss, calling the allegations “baseless” and “opportunistic.”

The event tests how insider trading laws apply to algorithmic stablecoins and the crypto trading desks that profited from the 2022 collapse that erased $40 billion in market value across UST and Luna.

The Allegation: A Telegram Channel Called "Bryce's Secret"

The estate’s complaint centers on a private Telegram group named after Bryce Pratt, a former Terraform intern who later joined Jane Street. The lawsuit alleges Pratt maintained ongoing contact with former Terraform colleagues and shared sensitive, non-public information about UST’s peg stability.

According to the filing, Pratt sent a message to Jane Street traders suggesting they should feel “slightly pleased” about their “informational advantage.” The estate argues this allowed Jane Street to liquidate its entire UST position on May 7, 2022 – nine days before the full implosion.

The Critical Curve Transaction

The complaint identifies a specific $85 million UST-to-USDC swap executed on Curve Finance as the key exit move. Blockchain analysis had previously flagged that transaction as a trigger for the peg breakdown. The lawsuit now claims the wallet that executed that swap belonged to Jane Street.

The timing is central. Jane Street’s $85 million Curve swap came just nine minutes after Terraform itself had quietly withdrawn $150 million in UST liquidity from the same pool. The estate argues Jane Street knew the withdrawal was coming and front-ran the liquidity drain.

The Profits: $134 Million Short Campaign

After exiting UST near $1, Jane Street allegedly built short positions across related assets as the Terra ecosystem collapsed. The lawsuit estimates those bets generated about $134 million in profit.

Internal communications cited in the complaint show traders discussing how to “decommission” wallets after a crypto analytics firm publicly noted that Jane Street had “made a killing.”

The Defense: Public Data vs. Material Non-Public Information

Jane Street’s motion to dismiss frames the lawsuit as a transparent attempt to extract money from a deep-pocketed defendant. The firm argues all trading decisions were based on publicly available data – including on-chain liquidity movements, social media sentiment, and Terraform’s own public communications.

What this means: The case hinges on whether the information shared in the Telegram channel was material, non-public, and knowingly used for trading. A 2023 federal ruling that UST and Luna are securities under the Securities Act gives the estate a stronger legal foundation. Proving causation and intent remains a high bar.

Jane Street also points out that Terraform’s own executives committed fraud, as previously found by federal courts. The firm argues losses from the collapse were caused by Do Kwon’s mismanagement, not by any trading desk.

Exposure: What Jane Street and the Market Face

Jane Street is one of the world’s largest proprietary trading firms, handling massive volumes across equities, fixed income, ETFs, and crypto. A federal insider trading finding would expose the firm to:
