The buying is entirely passive/index-driven — Vanguard, BlackRock, Morgan Stanley, Wells Fargo, and Schwab all doubled positions, consistent with CoreWeave entering or gaining weight in major indices or ETFs. This does not reflect an active fundamental thesis. Monitor for any active-manager 13F filings (next cycle) that could signal real conviction. The T. Rowe Price near-exit is negligible at $75K.
Executive Summary
Five mega-passive institutional investors (Vanguard, BlackRock, Morgan Stanley, Wells Fargo, Schwab) all doubled or more their CoreWeave positions in Q3 2025, adding a combined $1.37B in new holdings. One passive seller (T. Rowe Price) exited nearly entirely, trimming $75K. The cluster is entirely passive/index-driven, reflecting index rebalancing or ETF inflows rather than an active fundamental thesis.
