Insights

Large shareholder reported multiple open-market sales on 10/15/2025; ownership remains substantial across funds; impact appears neutral.

Multiple related reporting persons affiliated with Magnetar disclosed open‑market sales of CoreWeave, Inc. (CRWV) Class A shares on 10/15/2025. Transactions executed at weighted average prices ranged from roughly $136.49 to $141.00 per share, across several price buckets. Post‑trade, the group still reports large indirect holdings in distinct funds, with updated balances disclosed for each entity.

These are secondary sales by a 10% Owner and Director group, not issuances by the company. The filing specifies price ranges and offers to provide full breakdowns upon request, indicating standard execution detail for aggregated trades. No derivative transactions were reported in Table II.

What to watch: further Form 4s that change the reported indirect balances, any future crossing of ownership thresholds, and subsequent disclosure timing relative to quarter-end or other events. The signatures dated 10/17/2025 confirm timely reporting after the 10/15/2025 trades.
