My take? The biggest fortunes here come from a mix of inherited ownership, private industry, and high-scale corporate holdings.
1. Alice Walton - $101B
Overview: Alice Walton holding the top spot shows how dominant Walmart-linked family wealth remains in the U.S. My take? This is legacy capital at full scale, and it still sets the pace for everyone else on this list.
