Apart from the Terraform lawsuit, Jane Street was accused of market manipulation in India last year

Public records indicate that in July 2025, India’s Securities and Exchange Board of India (SEBI) imposed an interim ban on Jane Street Group, accusing the firm of manipulating Indian indices—including the Bank Nifty—through high-frequency trading strategies. Per SEBI’s allegations, on derivative expiration dates, Jane Street manipulated indices by purchasing underlying stocks and futures in the spot market to inflate index values, then profited from options positions (leaving small investors with unfavorable trading prices). SEBI has frozen roughly 4.843 billion Indian rupees (about $565 million) in Jane Street assets and barred the firm from trading in India’s securities market. Jane Street has recently faced a wave of market manipulation claims: - The court-appointed bankruptcy trustee for Terraform Labs has sued the firm in the U.S. District Court for the Southern District of New York, alleging Jane Street used non-public insider information from Terra insiders to front-run trades during the Terra collapse and profit. - The crypto community has also accused Jane Street of manipulating Bitcoin ETF and Silver ETF markets via its market-making activities.
