About 13F Holding

Last updated October 23, 2026

13F Holding shows what investment managers own, using the quarterly Form 13F filings they make to the SEC. It covers every 13F filer (about 10,000 managers) and every stock they report (about 34,000), from Q1 2024 to the latest quarter. A short list of famous investors sits on top.

Who runs it

13F Holding is an independent project run by one developer. It is not affiliated with the SEC or with any fund, manager or company on the site, and no one pays to be featured.

How the data is updated

All data comes from SEC EDGAR. New filings are added during each filing season, which peaks in the days before the 45-day deadline (next: Nov 16, 2026). Before a quarter goes live, automated audits check it against the filings, and late filings and amendments are added as they arrive. The methodology explains how the pages are built.
