Ownership, not assumption
Browse billionaires by type
Explore how fortunes were created, inherited, held and controlled. Classifications are editorial attributes—not claims that every asset is personally owned.
Classification method
Current-list categories use annual source fields, normalized wealth-source text and deterministic classification rules. Uncertain political, royal and foundation structures remain outside the conventional ranking.
