Rhea-AI Filing Summary

Magnetar-related entities reported multiple dispositions of CoreWeave, Inc. (CRWV) Class A common stock on 08/22/2025, selling shares at $98.19 per share. The filing shows aggregate open-market sales of 20,733 shares executed on that date across several Magnetar funds and affiliates. The reporting group also discloses collar arrangements on certain holdings: for specified lots the holder wrote covered call options and purchased put options with strike prices of $160 (call) and $70 (put) expiring 03/20/2026, where only the in‑the‑money option can be exercised at expiration. The filing lists multiple Magnetar entities and disclaims beneficial ownership except for pecuniary interest. The report was signed by an attorney‑in‑fact on behalf of David J. Snyderman.

Insights

TL;DR: Magnetar affiliates sold a modest block of CRWV shares and hold collars on larger positions; transactions appear structured, not a single large block sale.

The Form 4 documents sales totaling 20,733 Class A shares at $98.19 on 08/22/2025 across multiple affiliated funds. In addition, the filing discloses collar-type derivative positions (written calls and purchased puts with $160/$70 strikes) covering specified lots expiring 03/20/2026. The reporting parties include Magnetar Financial LLC, Magnetar Capital Partners LP, Supernova Management LLC and David J. Snyderman, each disclaiming beneficial ownership except for pecuniary interest. From a capital-markets perspective, the explicit facts show organized risk-management via collars and smaller outright sales rather than a large, single-disposition event.

TL;DR: Multiple Magnetar entities filed coordinated disclosures showing sales and option collars; signatures are by attorney‑in‑fact for the manager.

The Form 4 lists coordinated transactions by affiliated reporting persons and includes the standard disclosure that the entities disclaim beneficial ownership beyond pecuniary interest. The signature block shows an attorney‑in‑fact executed the filing on behalf of David J. Snyderman as manager. The document also specifies that the underlying securities are held by various named funds and entities and that some shares are subject to a collar (covered call/put) arrangement. These are routine governance and disclosure details rather than indicia of governance change.
