AI Insider Summary

McBee Brannin (CIK 0002058103, 1,342 transactions) has filed exclusively at CoreWeave, Inc. (CRWV) since December 2024 — a 19-month file with zero buy-side events and 8,330,430 sell-side shares across the lifetime aggregate. The most recent session on June 15, 2026 contains a cluster of four C-code non-market dispositions totaling 194,000 shares (3,000 + 25,000 + 25,000 + 144,000) alongside six S-coded market sells totaling roughly 2,891 shares at prices from $104.47 to $108.61 — the C-block dominates the day by volume and likely represents a derivative settlement, plan transfer, or similar non-market-priced event, while the S-block is genuine open-market disposition at a narrow price band. The June 2026 activity continues a consistent pattern: this insider's entire Form 4 register is sell-side outflow. There is no P-coded open-market buy, no secondary issuer, no diversification layer, and no obvious plan-award counterbalance — the file reads as a concentrated position being wound down through whatever combination of market sales and non-market disposals the filing calendar requires.

Brannin's CRWV file begins December 31, 2024 and runs through June 15, 2026 — just 19 months producing 1,342 transactions. That density is itself notable: it implies a large starting position that generated many small disposition events rather than a slow, low-volume liquidation. CoreWeave went public in 2025, so this file captures the insider's full public-company Form 4 history.

The June 15, 2026 session: C-codes dominate.
