Questions
What does Atreides Management hold?
Atreides Management disclosed 49 positions worth $14.3B in the Q2 2026 13F filing. The largest is SPCX at 32.6% of the disclosed book. A 13F lists long US equity positions only.
What did Atreides Management buy and sell last quarter?
Comparing the Q2 2026 filing with the quarter before, the largest moves were New SPCX, Added QQQ, Trimmed ALAB, New CBRS. Changes are measured against the previous filing, not against trades, because a 13F does not disclose trades.
How current is this?
This is the Q2 2026 filing, covering positions held on Jun 30, 2026. A 13F is due 45 days after the quarter ends, so the most recent filing is always at least six weeks behind the market, and the manager may have changed the book since.
