Insights

Routine insider sales disclosed; administrative in nature.

The filing lists multiple open‑market sales by a director and 10% owner of CoreWeave on 10/09/2025 at weighted average prices between $139.15 and $143.13. Footnotes clarify that detailed trade‑by‑trade data is available upon request, which is standard for aggregated price reporting.

Holdings are reported as indirect through several Magnetar‑affiliated funds, with each fund’s balance shown after the respective sale lines. This is a disclosure event rather than a capital raise; cash proceeds accrue to the selling holders. Market impact depends on size relative to float, which is not provided in the excerpt.
