Who is the chairman of Walmart's board of directors as of 2025?

Greg Penner was chairman of Walmart’s board of directors as of 2025. Walmart’s 2025 proxy materials identified him as the company’s non-executive chairman, while Doug McMillon served separately as president and CEO.

Penner joined Walmart’s board in 2008 and became vice-chairman in 2014. In 2015, he succeeded Rob Walton as chairman. He is also a founder and general partner of Madrone Capital Partners and became CEO and an owner of the Denver Broncos after the Walton-Penner group acquired the team in 2022.

The Walton family names in the answer choices can cause confusion. Rob Walton was Walmart’s previous chairman, while Alice Walton and Jim Walton are members of the Walton family but were not the board’s chairman in 2025.

Walmart has kept the chairman and CEO roles separate since 1988. That arrangement allows the CEO to manage daily operations while the outside chairman focuses on board oversight and governance.
