SEC-registered and state-registered firms that report RAUM, ranked by RAUM. 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). RAUM is regulatory assets under management (Form ADV Item 5.F(2)(c)) as reported in each firm's latest Form ADV filing in the data of October 2, 2026, usually as of the firm's last fiscal year end. Firms reporting no RAUM are not ranked. 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.
