Insights

Routine Form 4 discloses open‑market sales with ranges.

The filing lists multiple open‑market sales of CoreWeave Class A shares on 10/15/2025 by Magnetar‑related reporting persons. Prices are reported as weighted averages with stated intra‑day ranges, which is common when trades are executed in numerous lots.

Indirect beneficial ownership remains across several funds, with share counts shown per fund after the trades. The footnotes include standard disclaimers of beneficial ownership limited to pecuniary interest, and identify the specific Magnetar entities holding the shares.

This is primarily an administrative ownership update. Actual market impact depends on trade size relative to daily volume and broader holder decisions; the filing itself does not provide that context.
