Jane Street more than doubled its Nvidia stake last quarter, filings reveal
Jane Street, one of Wall Street’s leading quantitative trading firms, more than doubled its Nvidia holdings in the third quarter, according to regulatory filings released Thursday and reviewed by Fortune.
Key points
- The regulatory disclosure, known as a 13F, doesn’t reveal exactly when Jane Street purchased the shares, or how much the firm has gained or lost on its bets though.
- Jane Street traders could, in theory, have shorted Nvidia after the reporting period ended and made money from the subsequent decline.
- The filings show what Jane Street held in late September, not what it owns now, and leave out short positions.
Reuters reported in August, citing a person familiar, that Jane Street had so far generated more than $40 billion in trading revenue in 2026.
The 13F also discloses that Jane Street holds a large amount of puts and calls, which are reported using the value of the underlying shares, rather than the market value of the options themselves.
Additional details
- Jane Street told employees that the drawdown had left its investment roughly flat for the year, though it remained profitable over the full period, per Reuters.
- That same Reuters report over the summer said Jane Street took a $15 billion hit, partly from its exposure to AI-focused hedge fund Situational Awareness.
- Those notional figures can make positions look far larger than the sums actually invested, while revealing little about the firm’s overall exposure once offsetting trades are taken into account.
- Huang stepped down on Thursday after more than three decades at the helm of the company he cofounded in 1993.
- Just three days later, the New York Times reported that the 63-year-old also had an affair with Kimberly Powell, Nvidia’s vice president of healthcare.
