Wisconsin’s Wealthiest: These Are the Top Five Billionaires—and the Siblings Who Share the No. 6 Spot

They are founders and heirs of companies that range from legacy products to new technologies.

Most people associate Menards with the tagline “Save Big Money!” But it’s the home improvement chain that also continues to make big money for its founding family. John Menard, Jr. tops the 2022 list of richest billionaires who are residents of Wisconsin, according to Forbes.

This list is watched so closely that Forbes has created its own real-time billionaire tracking website following the daily ups and downs of their portfolios, using stock prices and exchange rates. 

For example, John Menard made $200,000 in the 24 hours leading up to this article being published while the sibling heirs to the S.C. Johnson Co. lost $2 million in a day. 

Don’t worry—the wild swings are all in a day’s work for these investments—and according to Forbes data analyzed by Americans for Tax Fairness and Citizen Action of Wisconsin, the state’s billionaires saw their total fortunes grow by 50% during the first two years of the coronavirus pandemic.

The S.C. Johnson Family

There are three additional billionaires living in Wisconsin. The siblings are members of the S.C. Johnson family of Racine along with one other sibling who lives out of state. All four are each worth $3.4 billion, which would put them at No. 857 on the list of world’s richest individuals—though their family fortune would rank second in the state if combined.
