Institutional ownership from SEC Form 13F filings. Investment managers with more than $100 million in U.S. equities must disclose their positions every quarter, within 45 days of quarter-end, so the holdings shown can lag the market by up to a quarter.

Institutional holdings are being reconciled with SEC filings. Holder totals and changes may be incomplete until reconciliation finishes.

Who Holds SPY

Last 8 quarters through Sep 30, 2026 (filing window open)

Each kind of 13F filer's share of the common shares 13F filers report. Holder type comes from regulatory records, never the filer's name; style, turnover and horizon are measured from each filer's own 13F book. The quarter selector does not change this card.

Jun 30, 2026, the newest closed quarter: 4,676 filers, like-for-like change +6.5%; actively managed books +10.9%; index-like books -12.5%.

Holder type Share Filers Change
Registered adviser 26.0% 3,185 -0.8%
Exempt adviser 1.2% 14 +4.1%
Adviser 1.3% 29 +39.8%
Bank 27.6% 67 +2.5%
Insurer 0.3% 8 +7.4%
Broker-dealer 1.6% 3 -0.7%
Benefit plan 0.1% 6 +16.8%
Non-US 0.9% 17 -36.2%
Holding company 12.2% 15 -14.6%
Unknown 28.6% 1,332 +37.7%

The Sep 30, 2026 filing window is still open, so its bar shows only the filers that have filed so far.

How the mix is measured

Shares are 13F common shares restated to today's split basis; options and principal amounts are left out. The change compares only filers with a 13F in both quarters and keeps each filer in its bucket of the later quarter on both sides; a filer that continues under a new CIK is compared through its successor. Holder type comes from each filer's current regulatory profile; client base and private funds come from the Form ADV roster current at each quarter end (rosters from December 2019, so an earlier quarter reads Unknown). Style, turnover, horizon and book size are measured from each filer's 13F book in the newest measured quarter, and Not measured means none was. Actively managed books are those measured systematic-like, concentrated or diversified active.

Excluded 70 holders with no observed 2026-03-31 13F and 59 holders with no observed 2026-06-30 13F. Compared across CIK changes: 4 filers continue as Evelyn Partners Group Ltd; JANUS HENDERSON GROUP PLC continues as Jupiter Topco LLC; Trask Adam Roland continues as Burnham & Co LLC.

Conviction and Crowding

4,674 13F filers, quarter ended Jun 30, 2026

Measured across every 13F filer's common-share book once the quarter's filing window closed. Crowding counts filers with high turnover or that advise private funds on Form ADV.

Estimated Holder Cost Basis

Quarter ended Jun 30, 2026, on that quarter's share basis

Estimated, never filed: each 13F buy is costed at its quarter's average traded price and each sale keeps the average cost, so this is what holders paid on average if they traded evenly through each quarter.

How fund types are measured

Each fund series counts once, with its latest Form N-PORT report dated inside the quarter; only long share positions count, restated to today's split basis. The fund type is the series' latest Form N-CEN answer on or before the quarter end (the index-fund box and the exchange-traded flag), never its name. Unclassified funds have no usable N-CEN; unit investment trusts are among them, so index ownership is a floor. Funds sit inside their advisers' 13F reports, so these shares overlap the 13F figures and are never added to them.
