Jane Street Group's Indian unit, JSI Investment Pvt, reported a sharp rise in trading gains and profits in FY25 before its activities were halted by the Securities and Exchange Board of India (SEBI) over alleged market manipulation.
As per Bloomberg, JSI Investment Pvt recorded trading gains totalling ₹4,700 crore in the financial year ending March 2025, a near six-fold jump compared to ₹790 crore in the previous year.
After accounting for charges, the company posted an after-tax profit of ₹2,840 crore, reflecting a year-on-year increase of 494%. This data is based on corporate filings with the Indian government.
The surge in profit was reported prior to regulatory intervention by SEBI, which raised concerns around market manipulation related to the firm’s trading activities, including derivative strategies centred around short straddles.
On July 3, 2025, SEBI issued an interim order accusing Jane Street of manipulating the local stock markets.
According to SEBI, the group earned profits exceeding $4 billion through stock, futures, and options trading since April 2022. Shortly after, trading operations were halted, pending investigation.
Jane Street has disagreed with SEBI’s findings and has appealed in a Mumbai court, seeking access to relevant documents essential for its legal defence.

Despite regulatory developments, other trading firms such as Hudson River Trading LLC and Optiver Holding BV also reported strong profit growth in India. This reflects sustained activity among high-frequency trading entities up to the point when regulatory actions were enforced.
A separate Jane Street entity, JSI2 Investment, reported a trading loss of ₹150 crore during the same period. Despite this, it received a capital infusion of ₹860 crore and had borrowings amounting to ₹3,200 crore as of March 2025.
Filings submitted in December 2025 confirmed that the concerned entities had ceased all trading in securities and derivatives. They noted that they would evaluate any decision regarding resuming operations at a later time.
Jane Street India reported significant gains amounting to ₹4,700 crore and a 494% rise in profit before SEBI-imposed restrictions. Following regulatory scrutiny, trading operations have been suspended while appeals are ongoing in court.
