What is Jane Street and how it made profit by gaming Dalal Street

Massive Profits, Alleged Manipulation: Jane Street made Rs 43,289 crore in options profits while incurring deliberate losses in equities and futures. SEBI alleges this was a manipulative strategy to rig index movements.

Intraday Index Rigging: The firm allegedly inflated Nifty Bank in the morning through aggressive buying, then crashed it by selling—all to benefit their large options bets on expiry days.

SEBI Cracks Down: SEBI froze Rs 4,844 crore, banned Jane Street entities from the market, and restricted access to their accounts, calling it one of the biggest actions against a foreign trader.

What’s Next: Jane Street has 21 days to respond. The case could reshape SEBI’s approach to regulating foreign players using complex trading strategies in Indian markets.

Jane Street is a global trading firm known for its expertise in ETFs and derivatives. Founded in 2000, it uses quantitative strategies to trade across markets worldwide and operates in 45 countries with over 2,600 employees.
