Every SEC-registered RIA in Delaware, 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 Delaware
- How many RIAs are in Delaware?
- 38 RIAs registered with the SEC list a main office in Delaware 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.

- By regulatory assets under management as filed on Form ADV, the largest SEC-registered RIA headquartered in Delaware is BlackRock Capital Management, Inc. in Wilmington, at $172.6B. 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.
