Which custodians RIAs use, from their SEC filings: each adviser lists the custodians holding 10% or more of its separately managed account assets, and how much. 7,353 wealth managers and planners, latest filings through December 2024.
Presented byYour company here · Sponsor this pageRead with care: the SEC publishes custodian names only in its bulk Form ADV data, so this is as of December 2024 (the monthly SEC files say whether an adviser uses a custodian, not which one). It covers SEC-registered RIAs only, not state-registered firms or broker-dealers. It counts only custodians holding 10% or more of a firm's separately managed account assets. So it understates custodians that grew fast since then, Altruist above all, whose reported platform assets are far larger than this shows.
Wealth managers and planners. Each box is sized by the number of RIAs using that custodian, or by the assets it holds for them. Hover for the numbers; click to open its page.
RIAs where half or more of the assets are for individuals. Many use more than one custodian, so shares of RIAs add up to more than 100%.
