MARVELL TECHNOLOGY INC
2,283 institutions still hold MARVELL TECHNOLOGY INC as of Q2 2026. Tracked across SEC 13F-HR filings, with insider and 13D/G activity surfaced alongside.
Marvell Technology Inc (MRVL), the data-center semiconductor and connectivity chipmaker whose custom ASIC and Ethernet switching franchises ride the AI-infrastructure build-out, now carries nearly $72 billion in institutional ownership spread across 1,488 filers — a population size that places it among the most broadly held large-cap semiconductor names in the 13F universe. The Q1 2026 register tells a coherent and broadly bullish story: FMR (Fidelity) added roughly $2.2 billion and became the single largest holder at $13 billion, BlackRock added $1.2 billion to its $6.3 billion position, and two simultaneous Vanguard passive entries — from Vanguard Capital Management and Vanguard Portfolio Management — together added $7.2 billion in newly-created index positions, signaling that Marvell crossed a market-cap or liquidity threshold that triggered index inclusion during the quarter. Offsetting that inflow, UBS trimmed roughly $224 million and Franklin Resources reduced by $145 million, but these are minor notes against the direction of the register. The single most distinctive feature of the Q/Q flow is the absence of any meaningful selling pressure from the active discretionary cohort: Ameriprise, Goldman Sachs, Invesco, and Millennium all added, while market-maker inventory (Jane Street and Susquehanna) also built positions. The net read on the register is that Marvell's AI-adjacent data-center exposure has made it a mandatory-buy name for both passive and active large-cap growth managers — and that positioning is not yet showing signs of rotation fatigue.
