What is Ken Griffin's biggest holding?
AMZN is the largest reported position at $2.6B, about 1.7% of the reported book, held as 10,882,003 shares.
What did Ken Griffin buy recently?
Ken Griffin opened 1159 new positions in the latest quarter. The largest new buys were SPCX. Ken Griffin also added to 37 existing positions, including AMZN, AAPL, MSFT and ELECTRONIC ARTS INC.
What did Ken Griffin sell recently?
Ken Griffin reduced 7 reported positions last quarter, the largest of them being NVDA, MU, META, INTC and TSLA. Note that a position exited completely stops appearing in the 13F entirely, so full exits show up as a name disappearing rather than as a sale.
Is Ken Griffin buying or selling right now?
Across the reported book, Ken Griffin added to 37 positions and trimmed 7, which makes the latest quarter a net buying one. "Right now" is the important caveat: a 13F is a snapshot as of the quarter end, filed up to 45 days later, so it shows what was held then, not what is held today.
What fund does Ken Griffin run?
The filings on this page come from Citadel Advisors, SEC CIK 1423053. That is the entity that files the 13F, which is why holdings are reported under the firm name rather than the person's name.
Is this Ken Griffin's current portfolio?
No. It is the most recent one that has been publicly filed. Institutional managers report holdings quarterly on Form 13F, as of the last day of the quarter, with up to 45 days to file. This page reflects the filing dated August 14, 2026 and updates automatically when the next one hits SEC EDGAR.
Does this show Ken Griffin's short positions or options?
Mostly no. A 13F covers reported long U.S. exchange-traded equity positions and some equity options and convertibles. Short positions are not disclosed, and neither are bonds, cash, commodities, currencies, or foreign-listed holdings. A manager with a large short book or heavy non-equity exposure can look very different in a 13F than in reality.
How do I track Ken Griffin's next moves?
This page rebuilds straight from SEC EDGAR, so the next 13F appears here as soon as it is filed. New stakes disclosed between quarters on Schedule 13D and 13G show up on the Smart Money page ahead of the next 13F, because those filings are due within days of crossing a 5% ownership threshold rather than at quarter end.
