Every SEC-registered RIA in California, by regulatory AUM

The default sort is regulatory assets under management as each firm filed it, which puts asset managers and wealth managers on one list. The toggle for firms where individuals and high-net-worth individuals hold the majority of assets is what separates them, using the firm's own Form ADV Item 5.D figures.

Questions people ask about RIAs in California

How many RIAs are in California?
1,871 RIAs registered with the SEC list a main office in California in the SEC's Form ADV data as of Sep 1, 2026. That count excludes state-registered RIAs, which generally manage under $100 million and file with the state rather than the SEC, and firms whose address is suppressed on Form ADV.
What is the largest RIA in California?
By regulatory assets under management as filed on Form ADV, the largest SEC-registered RIA headquartered in California is BlackRock Fund Advisors in San Francisco, at $4.28T. Regulatory AUM counts all assets a firm manages, so the largest filer in a state is often an asset manager rather than a wealth manager.
How many California RIAs manage more than $1 billion?
626 of the 1,871 SEC-registered RIAs headquartered in California report regulatory assets under management of $1 billion or more. The median firm in the state reports $472.5M.
Where does this data come from?
From the SEC's monthly Form ADV data file for SEC-registered investment advisers (ia09012026-registered.zip, data as of Sep 1, 2026). Each figure is as the firm itself reported it on Form ADV Item 5; the SEC does not verify it. Every row links to the firm's record on the SEC's Investment Adviser Public Disclosure site.
