How the Richest US Families Built Their Fortunes
Walmart founder Sam Walton built the family's wealth by pioneering low-cost retail logistics and leveraging the company's stock over decades, turning a single Arkansas discount store into a global empire. The Mars family expanded Mars Inc. from a small candy manufacturer into a sprawling private conglomerate that includes brands like M&M's, Snickers, Pedigree, and Whiskas, with ownership passed through trusts and holding companies.

The Koch family's wealth is rooted in oil refining, commodity trading, and diversified industrial holdings built by brothers Charles and David Koch, with current leadership continuing their private, long-term investment strategy. Other major fortunes come from tech, finance, and real estate, with families like the Waltons and Mars heirs using private holding structures to maintain control while minimizing public disclosures.
