Rhea-AI Filing Summary

CoreWeave insider sale arrangement by Magnetar group: Multiple Magnetar-related entities entered into variable pre-paid forward sale contracts that together obligate delivery of 400,000 shares of CoreWeave Class A common stock on 06/19/2026 (settlement determined by the Settlement Price). The contracts include a Floor Price of $120.00 and a Cap Price of $190.00, and specify tiered share delivery mechanics based on the Nasdaq closing price on 06/18/2026.

The reporting entities received cash proceeds in exchange for assuming the forward obligations totaling $46,351,859.27. The pledged shares remain subject to the contract through the pledge, while the reporting entities retained voting and dividend rights during the pledge period. The Form 4 lists the reporting parties (Magnetar Financial LLC and related entities and individuals) and disclaims beneficial ownership except for pecuniary interest.

Positive

Voting and dividend rights retained by reporting entities during the pledge term
Immediate cash proceeds of $46,351,859.27 received across the contracts

Negative

400,000 shares pledged and subject to delivery on 06/19/2026
Share delivery is price‑dependent (Floor $120.00, Cap $190.00), creating uncertainty in final share count transferred

Insights

TL;DR: A set of variable pre-paid forward contracts monetize equity now while leaving voting and dividend rights intact through settlement.

The transactions are structured as variable pre-paid forward sale contracts that obligate delivery of up to 400,000 Class A shares on 06/19/2026 using a Floor/Cap mechanism ($120.00 floor, $190.00 cap) that determines the number of shares deliverable based on the settlement price. In exchange, the entities received aggregate cash proceeds of $46,351,859.27, which effectively monetizes a position while deferring final share transfer.

Key dependencies and risks include the final Nasdaq closing Settlement Price on 06/18/2026, which will determine actual share delivery and remaining economic exposure. Monitor the Settlement Price on that date and potential accounting or tax treatment arising from the forward structures through mid-2026.

TL;DR: Voting and dividend rights were retained, but shares are pledged and subject to delivery, which affects future ownership breadth.

The filing states the pledged shares remain under the reporting entities' voting and dividend control during the pledge term, which preserves governance influence until the Settlement Date. However, the contracts pledge the indicated shares as collateral and create a binding obligation to deliver shares under specified pricing outcomes, exposing the current holders to possible reduction in beneficial holdings on settlement.

Investors should note the counterparty payment dates (on or about the contract entry) and the single Settlement Date of 06/19/2026 as the concrete milestone when ownership and voting influence could change materially depending on the Settlement Price.

Explanation of Responses:

1. The entity holding the indicated number of shares of Class A common stock (the "Common Stock") of CoreWeave Inc. (the "Issuer") entered into a variable pre-paid forward sale contract with a third party counterparty. The contract obligates the entity to deliver to the counterparty up to the indicated number of shares on June 19, 2026 (the "Settlement Date").
