Sam Walton on Corporate Governance

Walmart, headquartered in Bentonville, Arkansas, was founded in 1962 by the brothers Sam and Bud Walton in nearby Rogers and grew into an American multinational retail corporation operating supercenters, discount stores, grocery stores, pharmacies, and gas stations across the United States and nineteen other countries. It is the largest private employer in the world, with roughly 2.1 million employees, it sits at the top of the Fortune 500, and it also owns and operates the Sam's Club retail warehouses. The defining governance fact is that it remains a publicly traded family-controlled business — the largest such business on earth — because Sam Walton's heirs own more than half the shares through the Walton Enterprises holding company and their individual holdings. The company listed on the New York Stock Exchange in 1972, and it became the first traditional retailer valued above one trillion dollars in early 2026.

Samuel Robson Walton, born in Tulsa on October 27, 1944, the oldest of Sam and Helen Walton's four children, was prepared by temperament and training for the chairmanship he assumed two days after his father's death. A College of Wooster and University of Arkansas business graduate with a Columbia law degree, he practiced at the Tulsa firm Conner & Winters, which represented Walmart, before joining the company as a senior vice president in 1978; he became vice chairman in 1982 and was named chairman of the board on April 7, 1992. He held the chair until 2015, shepherding the family's control through decades of professional management, and with his siblings pledged roughly two billion dollars to the Walton Family Foundation between 2008 and 2013. A well-known collector of automobiles, he later led the family ownership group that purchased the Denver Broncos in 2022 for a record four-point-six-five billion dollars.

The Walton family remains the richest family in the world, and the structure of that wealth traces directly to the founder's estate planning. Sam Walton left his Walmart ownership to his wife Helen and their four children, and the family's stake is held in majority through the investment holding company Walton Enterprises. As of December 2014 the family collectively owned 50.8 percent of Walmart; after selling stock in 2018 it owns just under half. The three most prominent living members — Jim, Rob, and Alice Walton — have consistently appeared in the top twenty of the Forbes 400 since 2001, with individual fortunes recently estimated between one hundred ten and one hundred twenty billion dollars. The family held five spots among the ten richest Americans until 2005, and shares held by Bud Walton's two daughters through their own inheritances extend the family's reach further still.
