Iowa Billionaires and National Wealth Rankings
Comparison with Other U.S. Billionaires
Harry Stine regularly appears on the Forbes billionaires ranking alongside other major U.S. billionaires, though his wealth is largely tied to private companies rather than publicly traded stocks. His position among the richest people in Iowa reflects the state's strength in agriculture and agribusiness, where a small number of families control vast seed, land, and processing assets. Compared to tech or finance billionaires, his fortune is built on tangible, long-term demand for food and fuel production.
Why Iowa Has Fewer Billionaires Than Coastal States
