What it reported after the quarter end (Q2 2026)
The 13F shows the portfolio as of Jun 30, 2026. Since then Atreides Management 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.
What changed this quarter
57 positions with a change (8 new, 24 added to, 7 trimmed, 18 sold); also, 5 entered through an IPO. 12 are listed here: those of 0.5 points of the portfolio or more (up to 12).

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 (3)
Besides stocks, Atreides Management declared 1 put (they gain if the stock falls) and 2 calls (they gain if it rises) with a notional of $3.2 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
Type not verified: we have not assigned a type because we found no document that is enough to tell. Most 13F filers are in this situation: we only review in depth those that meet the portfolio criteria.
Not counted as a concentrated manager: more than 20% is options. Its portfolio is shown all the same, but it is left out of manager counts, the consensus and the ranking. How this is decided
Managers of a similar size
A 13F portfolio value between a third and three times this one, whatever the type of filer. It is not a comparison of what they hold.
