About Me

Kate MacMillan Reed is one of 21 billionaire heirs to Cargill, America's largest private company. Her great-great-grandfather, W.W. Cargill, founded the business as a single grain warehouse on the end of an Iowa railroad line in 1865. The family still owns roughly 90% of Cargill, which did $154 billion in 2025 sales across food, agriculture, financial and industrial divisions. She's one of nine billionaire siblings who inherited stakes in the company from their father John H. MacMillan III, who died in 2008.
