Jane Street More Than Doubled Its Nvidia Holding in the Third Quarter, Filing Shows

Jane Street held 23.8 million Nvidia shares on September 30, worth about $5.44 billion at that day's price of $228.38, up from 11.8 million shares worth $2.4 billion three months earlier, Fortune reported from the Form 13F filing. Nvidia was the firm's second-largest disclosed holding, behind the SPDR S&P 500 ETF Trust.

The filing says little about whether Jane Street is betting on Nvidia. It shows positions only as of late September and leaves out short positions, so the firm could have sold the stock short since then. It also does not show when shares were bought or whether the firm made or lost money on them. Jane Street also reported large holdings of Nvidia put and call options. 13F filings value options at the price of the underlying shares rather than what the options cost, so these positions can look far larger than the money at stake. Because Jane Street may hold offsetting trades, a large reported position is not necessarily a bet on the stock's direction.

Jane Street did not immediately respond to Fortune's request for comment.

Nvidia shares fell nearly 13% over five days and hit a 17-month intraday low on Thursday, after Jensen Huang stepped down as chief executive following reports of extramarital affairs. One of those reported relationships was with Alice Huang, a former Megaspeed executive whom US authorities suspect of working for Beijing. Chief financial officer Colette Kress has been named interim chief executive.

Jane Street has been having a strong year. Reuters reported in August that the firm had generated more than $40 billion of trading revenue so far in 2026, already above its $39.6 billion total for 2025. Jane Street has not confirmed those figures.
