Terraform Labs Trustee Sues Jane Street Over Alleged Insider Trading During TerraUSD Collapse

Terraform Labs Trustee Sues Jane Street Over Alleged Insider Trading During TerraUSD Collapse

Terraform Labs’ bankruptcy trustee accuses Jane Street of insider trading, alleging preemptive UST sales tied to the 2022 collapse, which Jane Street denies.

Fact Check
The strongest evidence comes from Inner City Press, which has an established record for accurate reporting on filings and court proceedings, especially in the Southern District of New York. That outlet reportedly covered a case where the court-appointed administrator for Terraform Labs filed a complaint against Jane Street, claiming that the trading firm engaged in misconduct involving approximately 85 million UST and used nonpublic information to its advantage. This report appears to be based on court documents, making it a credible secondary source with high relevance. Other listed pages do not contradict this claim, but they also provide little direct confirmation or additional primary evidence. Because the reporting aligns with known patterns of Terraform’s bankruptcy-related litigation and involves an identifiable plaintiff and defendant, the statement is likely true. However, absence of a directly accessible primary court filing reduces certainty somewhat, hence a medium-high rather than full high confidence rating.
