SPDR S&P 500 ETF TRUST
4,897 institutions still hold SPDR S&P 500 ETF TRUST as of Q1 2026. Tracked across SEC 13F-HR filings, with insider and 13D/G activity surfaced alongside.
SPY registers 4,512 institutional filers holding roughly $877 billion in aggregate 13F value, and the register has an unmistakable structural story: market-making desks Jane Street and Susquehanna dominate the top table by reported value, ahead of BlackRock, Vanguard, and State Street. That rank inversion tells you SPY holder base is as much a derivatives and flow vehicle as it is a passive benchmark fund, with prime-brokerage and custodian names filling out a financial-services-tier that does not appear at the same scale in most other equity-ETF registers.
