About Me

John G. MacMillan IV is one of 21 billionaire heirs to Cargill, America's largest private company. His 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. The Cargill-MacMillan family collects an estimated 18% of net profits as dividends every year. He's one of nine billionaire siblings who inherited stakes in the company from their father John H. MacMillan III, who died in 2008.
