The largest US family offices on our lists that file with the SEC
Pathstone files the largest figure of the US family offices on our lists: $110.3BN in regulatory assets (Form ADV, ), ahead of Cresset ($78.9BN) and Bessemer Trust ($47.0BN). All ten are multi-family offices, so each figure includes the money of every family the firm serves; 7 have their main office in New York.
Ranked by regulatory assets on the latest Form ADV, largest first.
Source: SEC Form ADV Item 5.F (filed Mar 2026 to Sep 2026), as ranked on Largest Family Offices in the United States, and each firm’s own site for its kind.
The ten are the top of the 101 US family offices on our lists that file Form ADV; all 355 are on Largest Family Offices in the United States.
No US regulator counts family offices
No US regulator publishes a full count. Under the SEC's family office rule, an office that serves one family need not register, so most never file. When it adopted the rule in , the SEC wrote that estimates of the number of family offices in the United States vary widely, from less than 1,000 to 5,000.
