Showing all wealth firms, including wirehouses and broker-dealer firms. Independent RIAs only

SEC-registered firms ranked by compound annual growth in RAUM over the three years between the SEC snapshots of October 5, 2023 and October 2, 2026, for firms with at least $100 million in RAUM at the start. The value is a fraction per year and base_value is the starting RAUM. Firms growing more than 100 percent a year are left out: on Form ADV that almost always reflects a merger, an acquisition or assets moved from an affiliated adviser rather than growth, and each firm's own page still shows the change. 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). Only SEC-registered firms are ranked: the state-registered firm data is current only, with no earlier snapshots. Growth includes market movement, net new assets and acquisitions. 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.
