Mark Shoen Net Worth

Mark Shoen has an estimated net worth of $4.8 billion, according to Forbes Real-Time Billionaires, Mark Shoen profile (figures as of October 20, 2026). That is up from $3.2 billion in 2019.

Mark Shoen is an American business executive tied to U-Haul for decades. He is vice president of the storage rental company U-Haul and the largest shareholder in its parent company, Amerco. His family connection to the business goes back to 1945, when his parents, L.S. and Anna Mary Shoen, cofounded the truck and trailer rental company. He later became part of the leadership group that helped steer the company through major operational and investment decisions.

His wealth comes from ownership in the U-Haul business and related self-storage operations. By the mid-1970s, he and several brothers had moved into top management at U-Haul. In 1979, he and Joe Shoen left during a dispute over the company's direction. In 1986, they helped take control, then backed changes that included business diversification, workforce cuts, and a $1.2 billion fleet upgrade. He later served as president of U-Haul and stayed involved through several leadership roles.

How Mark Shoen built his fortune

Shoen's money is closely linked to U-Haul and the company above it. He is the largest shareholder in Amerco, the publicly traded parent of U-Haul, and Forbes says he owns roughly one-fifth of that business. He also served in several senior roles, including president of U-Haul by 1990, board positions in the 1990s, leadership in Phoenix operations through 2007, and a vice president role at an AMERCO subsidiary in 2008.

Another piece of his wealth comes from self-storage. Forbes says he is the majority owner of one of the largest private self-storage operations in the U.S., and that business works with U-Haul. After retiring from AMERCO in 2012, he continued with other business entities, including Foster Road LLC, Blackwater Investments, Inc., and control over the general partner of Mercury Partners, L.P. In 2026, a company proxy said Shoen, Joe Shoen, and their controlled companies held more than 50 percent of voting power.

Forbes net worth updates

Forbes has tracked big swings in Shoen's fortune over time. Its World's Billionaires List estimated him at $3.2 billion in 2019, then $2.9 billion in 2020. The estimate later climbed to $3.9 billion in 2021, $4.7 billion in 2022, and $4.9 billion in 2023. Forbes then put him at $5 billion in 2024 and $5.1 billion in 2025, showing how much value was tied to his ownership stake.

More recently, the estimate moved lower and then higher again. Forbes valued him at $3.9 billion on its 2026 World's Billionaires List, while its real-time billionaires tracker showed $4.8 billion in October 2026. The main drivers named in the record are his large holding in U-Haul's parent company and his self-storage interests. Because so much of his wealth is connected to those holdings, changes in Forbes estimates can be sharp from year to year.
