Rhea-AI Filing Summary

CoreWeave, Inc. reported a Form 4 showing that investment entities advised by Magnetar Financial LLC completed the settlement of variable pre-paid forward sale contracts tied to Class A common stock. The restructuring transactions covered 800,000 shares in total across multiple Magnetar-managed funds.

The contracts were originally entered on October 9, 2025 and settled on June 22, 2026. Because the June 18, 2026 settlement price of $117.95 was below the $120.00 floor price, the entities delivered all pledged shares to the third-party counterparty. During the pledge period they retained voting and dividend rights in these shares.

The reporting persons, including Magnetar Financial, Magnetar Capital Partners LP, Supernova Management LLC and David J. Snyderman, report these positions indirectly through various Magnetar funds and expressly disclaim beneficial ownership except to the extent of their pecuniary interest.

6 terms

variable pre-paid forward sale contract financial

"settled a variable pre-paid forward sale contract that was entered into October 9, 2025"

Floor Price financial

"if the price ... was less than or equal to $120.00 (the "Floor Price")"

The floor price is the minimum price at which a security, asset, or offering will be sold or accepted, acting like a seller’s “bottom line” or a reserve in an auction. For investors it matters because it sets a visible downside limit and can influence trading, valuation, and expectations of risk—like knowing there’s a safety net that a sale won’t go below a set level.

Cap Price financial

"between the Floor Price and $190.00 (the "Cap Price")"

Pledged Shares financial

"the indicated number of shares, as reported in Column 5 (the "Pledged Shares")"

beneficial ownership financial

"disclaims beneficial ownership of these shares of Common Stock of the Issuer"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

pecuniary interest financial

"except to the extent of its or his pecuniary interest therein"

FAQ

How does the variable pre-paid forward contract on CoreWeave (CRWV) shares work?

The contracts required Magnetar-related entities to deliver CoreWeave shares on June 22, 2026. Delivered shares depended on the June 18, 2026 settlement price versus a $120 floor and $190 cap, using a formula that adjusted the share count based on where the price fell within that range.

Why were all pledged CoreWeave (CRWV) shares delivered under the contract?

All pledged shares were delivered because the June 18, 2026 settlement price of $117.95 was below the $120.00 floor. Under the contract’s terms, a price at or below the floor required delivery of the full number of pledged shares to the third-party counterparty at settlement.

Who actually holds the CoreWeave (CRWV) shares reported on this Form 4?

The shares are held by various Magnetar funds, including entities such as CW Opportunity 2 LP, CW Opportunity LLC and other Magnetar-branded funds. Magnetar Financial and related reporting persons disclose indirect interests and disclaim beneficial ownership beyond their economic, or pecuniary, interests.

Are these CoreWeave (CRWV) Form 4 transactions open-market buys or sells?
