Missouri has a new richest person: Pauline MacMillan Keinath

April 5, 2025 by Maria Santiago Leave a Comment

According to a recent Forbes report, Pauline MacMillan Keinath has become Missouri’s wealthiest billionaire.

Born on July 31, 1934, in Hennepin County, Minnesota, Keinath is the great-granddaughter of William Wallace Cargill, the founder of Cargill, the largest private company in the United States. She inherited a 9 percent stake in the company, which, as of June 2024, is valued at approximately $8.2 billion. ​

Keinath resides in St. Louis, Missouri, with her spouse and four children. In addition to her business interests, she has been involved in political contributions.

Notably, she continued to support Senator Josh Hawley after the events of January 6, 2021, donating $1,900 in the latter half of that year.

Furthermore, in 2023, her family became the largest donors to Andrew Bailey’s campaign for Missouri Attorney General, contributing $375,000 to the Life and Liberty PAC.

Many other Missourians made the Forbes rich list. They include:

  • Pauline MacMillan Keinath ($7.3 billion, 443rd nationally)
  • Jim Kavanaugh ($7 billion, 474th)
  • Jack Dorsey ($3.9 billion, 929th)
  • Rodger Riney & family ($3.9 billion, 929th)
  • Robert Clark ($2.9 billion, 1265th)
  • David Hoffman ($2 billion, 1763rd)
  • Jim McKelvey ($1.6 billion, 2110th)
  • Sam Altman ($1.5 billion, 2233rd)

Meanwhile, across the United States as a whole, the richest people are mostly ones you can probably guess the names of because they have become household names.
