As of the latest 13F quarter on record, Q1 2026.
7 of the hedge funds and marquee managers we track hold Costco Wholesale Corp in their latest SEC 13F filings — ranked by each fund’s disclosed position value.
Total position value across the 7–10 of the ~52 funds we track that held COST each quarter — not total institutional ownership. Value is as reported in each 13F (filed up to 45 days after quarter end), so it reflects the filings on record and moves with both position size and the reported price at quarter end.
Tracked funds that opened, added to, trimmed or fully exited COST between their two latest 13F quarters. Only funds with both quarters on record are counted; for the largest quant books we store the top 500 positions only, so their tail exits aren’t claimed here.
By disclosed value, as of each fund’s latest quarterly 13F.

Source: SEC Form 13F — each institutional manager’s quarterly holdings report, filed up to 45 days after quarter end, so every position here is a delayed snapshot, not a live book. Coverage is only the ~52 marquee funds and managers we track, not every institutional owner — a fund missing here may still hold COST. For the largest quant managers (Citadel, Millennium, Renaissance and the like) we store each filing’s top 500 positions by value, so a smaller stake in one of those books may not appear. 13F covers US-listed long positions only — short positions, non-US listings and most derivatives never appear in these filings, so a fund’s absence here says nothing about a short or overseas stake — and only holdings that resolve to a US ticker are shown. Shares and value are as reported in the filing; no market-price data is used.
