Insights

Magnetar‑advised funds reported sizable, but purely secondary, sales of CoreWeave shares.

Investment funds advised by Magnetar Financial LLC disclosed open‑market sales totaling 961,169 shares of CoreWeave Class A Common Stock on April 22, 2026, executed across 28 separate transactions. All transactions were non‑derivative stock sales, with no option exercises or new awards reported.

The reported prices are weighted averages, with underlying trades occurring between $118.00 and $124.75 per share, according to multiple footnotes. Footnotes also state that various Magnetar funds are the direct holders, and that Magnetar entities and David J. Snyderman disclaim beneficial ownership beyond their pecuniary interests, emphasizing that these are fund‑level portfolio moves rather than personal insider acquisitions.

Because the filing does not quantify CoreWeave’s total shares outstanding, the relative size of these sales versus the company’s equity base is not stated here. The filing does show that Magnetar‑related entities remain large, indirect holders after the transactions, with multiple post‑transaction share balances listed for different funds.

weighted average price financial
"The price reported in Column 4 is a weighted average price."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
investment adviser financial
"Magnetar Financial LLC serves as the investment adviser to each of CW Opportunity 2 LP..."
An investment adviser is a person or firm that professionally manages money and gives recommendations about buying, selling, or holding investments. Like a financial coach or guide, they have a legal duty to act in a client's best financial interest, so their advice, fees and potential conflicts can directly affect returns and risk — making their role important for investors who want informed, accountable help with portfolios.
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
"disclaims beneficial ownership... except to the extent of its or his pecuniary interest therein."
