India's markets regulator has widened an investigation into alleged market manipulation by U.S. securities trading firm Jane Street to include other indexes and exchanges, a source familiar with the matter said.

Between 2019 and 2024, derivatives trading volumes in India skyrocketed nearly 40×, making it the world’s largest derivatives market by volume. Ahuja pointed out that the real game-changer was the rise of the retail trader.

Following its ₹4,843 crore order against Jane Street Group for alleged index manipulation, Sebi Chairman Tuhin Kanta Pandey issued a stern warning that market misconduct — from domestic or foreign entities — will face zero tolerance.
