SEBI says an appeal by Jane Street Group LLC seeking more details and documents is a “dilatory” or delaying tactic. The regulator makes the remark a day after the Wall Street trading firm presses for additional information about the origins of SEBI’s investigation into its trading activities.

The dispute relates to SEBI’s market manipulation allegations tied to Jane Street’s trades in Nifty Bank derivatives. One outlet reports the regulator is examining large positions taken by Jane Street, including a ₹4,370 crore position in index futures and a reverse position worth more than ₹32,000 crore in options, which the firm reportedly profited from. The case is heard as part of Jane Street’s challenge to SEBI’s allegations, with the hearing continuing on Wednesday.

Across outlets, the core point is consistent: SEBI rejects Jane Street’s request for further documentation as an attempt to slow the process, while Jane Street seeks more context on the investigation. The outlets differ mainly in emphasis—some focus on the procedural dispute and timing, while others describe the scale of positions and the derivatives products at the centre of SEBI’s scrutiny.
