How Many Family Offices Are There? 724 We Can Verify in the US, UK and Gulf
Nobody knows exactly, because family offices do not have to register as family offices. What we can say is that 724 family offices can be tied to a public source in our data as of November 2026: 481 in the United States, 157 in the United Kingdom and 85 in the Gulf. That is a floor, not a census.
Key takeaways
- 724 offices in our file: 488 single family offices and 236 multi-family offices.
- 475 of them appear in an SEC filing. The rest come from company registers and the office's own website.
- Sellers and publishers state counts from 355 to more than 9,000. They use different definitions, so the figures cannot be compared directly.
- A single family office that serves one family is generally exempt from SEC registration, so filings cannot show them all.

Why is there no exact count?
- No register. There is no license or register for family offices as such. In the US, a single family office that serves one family is generally exempt from registering as an investment adviser.
- No fixed definition. Some counts include any wealthy family's holding company. Others need dedicated staff. Multi-family offices overlap with wealth managers.
- Private by design. Many offices have no website and use a name that does not mention the family.
- Different floors. A list built from SEC filings only sees offices large enough, or public enough, to file.
Method and limits
- Source
- SEC filings (Form ADV, 13F and Form D), company registers, and each office's own website.
- Inclusion rule
- An organization that describes itself, or is described in a filing, as a single or multi-family office, with a public source we can link.
- Fill
- 443 offices have named decision-makers, 204 have an assets figure from a filing, and 129 have an office email address.
- Limits
- This is the number we can verify, not the number that exists. 111 US offices have no state. Offices with no filing and no website are missing.
- Refresh
- Rows last checked in November 2026.
