Insights

Large 10% owner reported open‑market sales across multiple funds at $136–$140, lowering indirect holdings; governance‑relevant and potentially supply‑adding.

Multiple reporting persons affiliated with Magnetar disclosed open‑market sales of CoreWeave, Inc. (CRWV) Class A on 10/29/2025. Trades executed at weighted average prices within ranges of $136.03–$137.00, $137.03–$138.00, $138.26–$139.09, and $139.34–$140.10. The filing shows indirect ownership through several vehicles and notes standard beneficial ownership disclaimers.

Post‑transaction balances reported for each vehicle include: Magnetar Longhorn Fund LP 8,937,361; Magnetar SC Fund Ltd 1,198,721; Magnetar Structured Credit Fund, LP 8,634,511; Magnetar Xing He Master Fund Ltd 3,209,207; Purpose Alternative Credit Fund – F LLC 2,985,917; Purpose Alternative Credit Fund – T LLC 862,889. The form indicates filing by more than one reporting person and the status of Director and 10% Owner.

This matters because sales by a 10% owner can increase available float and inform views on ownership concentration. The disclosure aggregates prices as weighted averages; detailed fills are available upon request, which is typical. Watch for additional Forms 4 around settlement dates or further activity after 10/29/2025, and any future indication of trading plans that could clarify cadence.
