Rhea-AI Filing Summary

CoreWeave, Inc. (CRWV): Form 4 insider activity — Magnetar‑affiliated reporting persons disclosed multiple open‑market sales of Class A common stock on 10/13/2025. The filing lists several transactions reported at a weighted average price, with ranges noted by the filers.

Examples include: 75,022 shares sold at $141.5 (weighted average with trades from $141.00 to $141.66), 37,731 shares at $141.5 (same range), and 7,141 shares at $140.14 (trades from $140.00 to $140.45). Additional sales were reported at weighted averages around $140.15 (range $140.00–$140.25) and $143.26–$143.28 (range $143.00–$143.42).

The filing also lists “amount of securities beneficially owned following reported transaction(s)” for each fund line item, including 24,158,127 shares for one Magnetar‑managed entity and 6,001,151 shares for another, as reflected after the respective transactions.

Insights

Multiple Form 4 sales across Magnetar-managed funds at $140–$143.50.

The disclosure shows open-market sales in CoreWeave Class A by reporting persons affiliated with Magnetar on 10/13/2025. Prices are reported as weighted averages with specified intra-day ranges: approximately $140.00–$143.50. Individual line items include both the sale amounts and the post-transaction beneficial holdings for each fund line.

Because the transactions span several Magnetar-managed entities, activity reflects portfolio-level decisions rather than a single account. The filing does not aggregate totals; each row reports its own sale and updated beneficial ownership.

Future implications depend on further disclosures of ownership changes in subsequent filings; the filing itself provides transaction amounts, price ranges, and updated per-entity holdings without guidance.
