What's Happening

The headline fact is straightforward: Magnetar Financial, which has been reported as a 10% shareholder in CoreWeave, recorded a sale of CoreWeave shares totaling $213.8 million. That single line item has several immediate implications for investors evaluating CoreWeave's stock and ownership profile.

• $213.8 million, the reported value of the sale disclosed in the filing.
• 10%, the stake size attributed to Magnetar Financial, indicating the seller is a material holder.
• 163.15%, a key data point provided in the briefing material for context, which investors can use in valuation and performance comparisons.
• 62.22%, another supplied data point to factor into relative-momentum or growth comparisons.
• 0.34% and 0%, additional numeric metrics included in the source data set for deeper analysis.

Each of these numbers feeds into how you might value CoreWeave, assess ownership concentration, and model potential dilution or selling pressure. The combination of a large dollar sale and a 10% owner means market participants will be watching subsequent SEC filings and block trade prints.
