Showing all wealth firms, including wirehouses and broker-dealer firms. Independent RIAs only
Firms ranked by number of clients: the clients counted by type in Form ADV Item 5.D(a) to (n) plus clients for whom the firm has no RAUM (Item 5.C(1)), as reported in the latest filing in the data of October 2, 2026. Counts are approximate as firms report them; a client type marked "fewer than 5 clients" without a number adds nothing. SEC-registered and state-registered firms are both ranked. Independent wealth management RIAs are ranked: firms whose individual and high net worth clients hold at least half of their regulatory assets and that offer financial planning or portfolio management for individuals, leaving out broker-dealers, banks and their advisory arms. The all wealth firms view ranks the same way with those broker-dealer affiliated firms added. Asset managers, private fund managers, pension consultants and platform managers are never ranked (see the methodology). State lists use each firm's main office state, or its registration state when the main office is not public. The US list leaves out firms whose main office is outside the United States. Equal values share a rank and are listed by CRD number.
