Read the numbers in context.
Regulatory AUM measures assets reported on Form ADV. It is not revenue, investment performance or a measure of adviser quality. These firms can include institutional managers and fund advisers, not only personal wealth advisers.
Separate registrants within the same corporate group remain separate. Their reported assets may overlap. Head office location does not establish every market a firm serves.

Does this include every adviser in Washington?
No. It covers approved SEC-registered firms in our snapshot with a principal office in Washington and valid reported AUM. State-registered advisers, exempt reporting advisers and firms without known assets are excluded from the ranking.
How often does this change?
The page reads the published research catalog. It changes when we release a newer catalog, not every time a firm files. The snapshot date above and filing date beside each firm make that delay visible.
Is this a recommendation?
No. This is a factual size ranking for market research, not an endorsement or investment recommendation. Verify current status and disclosures in the linked SEC record.
