CoreWeave (CRWV) 10% Owner Magnetar Financial Sells 200,000 Shares
What Happened
Magnetar Financial LLC (reported as a 10% owner/adviser to several Magnetar funds) disposed of a total of 200,000 shares of CoreWeave, Inc. (CRWV) on June 22, 2026. The transfers resulted from the settlement of a variable prepaid forward sale contract entered into on October 9, 2025. The Form 4 shows the dispositions as derivative-related and reports $0.00 per share on the derivative lines; per the contract mechanics and the June 18, 2026 settlement price ($117.95), all pledged shares were delivered to the third‑party counterparty.
Key Details
- Transaction date: June 22, 2026 (settlement of prepaid forward entered Oct 9, 2025).
- Shares transferred: 200,000 shares in aggregate (multiple entries for different Magnetar funds).
- Reported price on derivative lines: $0.00 (disposition of derivative/pledged shares).
- Settlement price (used to determine deliverable amount): $117.95 on June 18, 2026 — below the $120 floor, so all pledged shares were delivered.
- Securities were held directly by various Magnetar funds (see footnotes: e.g., Magnetar Constellation Master Fund, Magnetar Lake Credit Fund, Magnetar Longhorn Fund, etc.).
- The filing indicates the pledged shares were transferred to the counterparty (footnotes state "transferred to the third party counterparty").
- Filing timeliness: filed 2026-06-23 for a 2026-06-22 transaction (not indicated as late in the provided excerpt).
Context
- This was an institutional disposition tied to a derivative contract (prepaid forward), not an open-market sale by an executive. Such settlements are contractual and do not necessarily signal manager sentiment about the stock.
- The mechanics: because the settlement price was at or below the contract floor, the contract required delivery of all pledged shares. The reported $0.00 on derivative lines reflects the nature of the derivative settlement reporting, not that the shares had no economic value.
No post-transaction aggregate beneficial ownership figure was provided in the excerpt; see the full Form 4 for holdings after the transfers and for the specific fund-level breakdown in the footnotes.
