Who are the top five richest people in the quad cities?

The Quad Cities region consists of Davenport and Bettendorf in Iowa, and Rock Island, Moline, and East Moline in Illinois. As of my last available data, the top five richest people in the Quad Cities are not publicly disclosed in a definitive ranking. Wealth rankings can fluctuate due to changes in stock prices, investments, and other financial factors. It is important to note that wealth is often privately held and not always transparent in local communities.
