Gwendolyn Sontheim Meyer is an American heiress tied to Cargill, one of the biggest companies in food and agriculture. She is a great-great-granddaughter of founder W.W. Cargill. Outside the family business, she is also known in equestrian circles. She is a show jumper and a sponsor of dressage. In 2011, she won the Prix Credit Suisse at the Geneva International Horse Show, adding a public sports achievement to a private family fortune.
Her wealth comes from an inherited stake in Cargill. Forbes says she inherited an estimated 8% holding in the company. The family still controls roughly 90% of Cargill, a business with operations in food, agriculture, financial, and industrial divisions. Forbes places her in the Food & Beverage industry. She spends much of her time on a farm in Rancho Santa Fe, California, where she trains horses that compete in show jumping.
How Gwendolyn Sontheim Meyer built her wealth
Meyer is rich because of family ownership in Cargill, not because she founded a company herself. Forbes says she inherited an estimated 8% stake in the food giant. Her family connection goes back to W.W. Cargill, who founded the business in Conover, Iowa in 1865. Cargill stayed in family hands over generations, and that long ownership base is the main reason she appears on the billionaire ranks.
The business behind her fortune is broad. Cargill works across food, agriculture, financial, and industrial divisions. Forbes notes that the family still owns roughly 90% of the company. In 2025, Cargill posted $154 billion in sales, showing the scale of the operation tied to her stake. Away from that business, Meyer is known for horses. She spends much of her time training show jumpers and also sponsors dressage.
What Forbes says about her fortune
Forbes has shown notable swings in Meyer's estimated wealth over time. It put her fortune at $4.3 billion in 2019, then $3 billion in 2020, before raising it to $4 billion in 2021 and $5.5 billion in 2022. The estimate later moved to $4.3 billion in 2023, then $4.6 billion in 2024 and again in 2025. Those changes track the value of a large inherited stake in a private family company.
The latest Forbes updates moved higher again. Forbes estimated her at $6 billion on the 2026 World's Billionaires List. On Forbes' real-time billionaires tracker, she stood at $5.3 billion as of October 20, 2026. Because her wealth is tied to Cargill, changes in the estimated value of that company can move her ranking. Cargill's huge sales base also helps explain why an inherited minority stake can still support a multibillion-dollar fortune.
