Rhea-AI Filing Summary

CoreWeave, Inc. saw large open-market sales of its Class A Common Stock by investment funds advised by Magnetar Financial LLC and related entities. On April 15, 2026, these Magnetar-managed vehicles sold a combined 2,604,094 shares in 27 open-market transactions.

The reported weighted average sale prices clustered around $117.79, $118.57, and $119.34 per share, with actual trades occurring within narrow ranges around each figure. After the sales, individual Magnetar-associated funds continued to hold multi‑million‑share positions in CoreWeave, and Magnetar and its affiliates formally disclaim beneficial ownership beyond their pecuniary interests.

Insights

Magnetar-advised funds sold 2.6M CoreWeave shares but retain large positions.

Investment funds advised by Magnetar Financial executed 27 open-market sales totaling 2,604,094 shares of CoreWeave Class A on April 15, 2026. Sale prices were tightly grouped around $118 per share, indicating block-style liquidity management rather than scattered retail-sized trades.

These are strong-signal sales (code S) by a disclosed ten percent owner group, but the filing also shows multi‑million‑share positions remaining at several Magnetar-related funds. Because the filing does not quantify CoreWeave’s total shares outstanding, the overall impact on ownership structure or float cannot be precisely gauged from this data alone.

Footnotes clarify that individual Magnetar entities and David J. Snyderman disclaim beneficial ownership except for their pecuniary interests. The absence of any reference to a Rule 10b5‑1 trading plan means the timing appears discretionary based solely on this disclosure, though broader motivations are not addressed here.

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.

ten percent owner regulatory

"each reporting person is marked as is_ten_percent_owner: 1"

beneficial ownership regulatory

"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."

indirect ownership regulatory

"direct_or_indirect: "I" and ownership_type: "indirect""

open-market sale financial

"transaction_action: "open-market sale""

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.

FAQ

At what prices did Magnetar funds sell CoreWeave (CRWV) shares?

The reported prices are weighted averages around $117.79, $118.57, and $119.34 per CoreWeave share. Footnotes state the actual trades occurred in narrow ranges, from $117.06 to $119.50, with detailed breakdowns available to investors or regulators on request.

Were the CoreWeave (CRWV) insider sales made under a Rule 10b5-1 trading plan?

The disclosure does not mention any Rule 10b5‑1 trading plan. The Form 4 describes the April 15, 2026 transactions as open-market sales by Magnetar-advised entities, without indicating they were executed under a pre-arranged trading program or automatic selling arrangement.

Who is actually selling CoreWeave (CRWV) shares in this Magnetar Form 4?

The sales are attributed to various Magnetar-managed funds, such as CW Opportunity 2 LP and other Magnetar vehicles. Magnetar Financial, Magnetar Capital Partners, Supernova Management, and David J. Snyderman all disclaim beneficial ownership of the CoreWeave shares beyond any pecuniary interest they may have.

How significant are Magnetar’s CoreWeave (CRWV) insider sales in this filing?

The filing shows 2,604,094 CoreWeave shares sold by Magnetar-advised funds on a single date, a sizable block for one holder group. However, the document also reports multi‑million‑share positions remaining, and it does not state what fraction of CoreWeave’s total outstanding shares this represents.
