What it reported after the quarter end (Q2 2026)
The 13F shows the portfolio as of Jun 30, 2026. Since then Citadel Advisors has filed these own trades with the SEC (Form 4, when it owns more than 10% of a company or holds a role in it) and stakes above 5% (13D and 13G). It is not everything it did: only what it must report before the next 13F.

It started trading this quarter: it appears in a 13F for the first time. The filing does not say whether the manager already held it before the listing, so it is not counted as a purchase.

Declared options (25)
Besides stocks, Citadel Advisors declared 12 puts (they gain if the stock falls) and 13 calls (they gain if it rises) with a notional of $701 bn. The 13F reports the value of the underlying shares, not the premium paid, so these figures look large and are not added to the portfolio. Nor does it say whether the option is bought or written, or its strike or expiry: it may be a hedge.

How we classify it
Not counted as a concentrated manager: its portfolio is not within 5 to 100 positions; its top 10 positions are under 45%; more than 20% is options; it is a quant or multi-manager firm; its 13F does not reflect a thesis. Its portfolio is shown all the same, but it is left out of manager counts, the consensus and the ranking. How this is decided
