10. The Duncan Family: $22.4 Billion, Oil and Gas

Energy industry entrepreneur Dan Duncan, former head of natural gas and crude oil pipeline company Enterprise Products, left equal shares of a nearly $10 billion estate to his four children when he died in 2010. Because of the timing of Duncan’s death, the New York Times reported his heirs might have benefited from a Congressional quirk that eliminated the federal estate tax for one year. But, Enterprise Products released a statement that Duncan had passed the “economic interest” in the company on to his children before his death. So, it’s unclear if they really reaped the rewards from the estate-tax lapse.

What is clear is that the siblings are even richer now than they were then. Forbes reports that since the senior Duncan’s death, the family fortune has more than doubled, padded by rising share prices and dividend payouts from the publicly traded affiliate, Enterprise Products Partners.

9. The (Edward) Johnson Family: $26 Billion, Money Management

Owning 49 percent of money management powerhouse Fidelity, the Johnson family is one of the wealthiest families in the country, reports Forbes. Edward C. Johnson II founded the firm in 1946, which has since grown to become the second-largest mutual fund company in the U.S. behind Vanguard, managing $1.8 trillion in assets. The founder’s son, Edward “Ned” Johnson III, controlled the company for nearly three decades before ceding the CEO spot at Fidelity Investments to his daughter Abigail in 2014. Son Edward Johnson IV runs a family-owned real estate company while another sibling, Elizabeth, is not involved in operations at Fidelity, reports Forbes.

8. The S.C. Johnson Family: $28.8 Billion, Cleaning Products

S.C. Johnson started as a salesman at a parquet flooring company in 1882, bought out the business a few years later and developed a floor wax for his customers that soon outpaced flooring sales. His son, Herbert Fisk Johnson, ran the company until 1928. Herbert died without a will, sparking a battle over inheritance that ended with a 60-40 split of the company between his two children, Herbert Fisk Jr. and Henrietta Johnson Louis.

Despite early differences, the family has managed to hold on to 100 percent of the company, which has estimated annual sales of $9.6 billion, according to Forbes. S.C. Johnson boasts a product portfolio of brands that include Pledge, Windex, Ziploc, Glade and more.

7. The Pritzker Family: $30 Billion, Hotels & Investing

Jay Pritzker and his brother Donald built the company behind Hyatt hotels and also found success as investors. But the family fortune was threatened in 2002 when two of Jay’s grandchildren sued their father Robert and other family members, claiming approximately $1 billion had been unlawfully siphoned from their trust funds, reports Daily Finance. Both grandchildren received $500 million and agreed to relinquish all future claims on the family assets in a 2005 settlement.

There are now 11 individual billionaires in the Pritzker family ranks, including U.S. Secretary of Commerce Penny Pritzker and movie producer Gigi Pritzker.

6. The Hearst Family: $32 Billion, Media

William Randolph Hearst built a publishing powerhouse that began when he listed himself as “proprietor” on the masthead of the San Francisco Examiner in 1887. Today, the company is focused on disseminating news though outlets such as Cosmopolitan magazine and ESPN. The Hearst Corporation has grown to include more than 200 media and information businesses in more than 150 countries.

William R. Hearst III, grandson of the company founder, serves as chairman of the board of directors. Actress and model Lydia Hearst ("Cabin Fever: Patient Zero") is William Randolph's great-granddaughter. Socialite and activist Amanda Hearst is another great-granddaughter of William Randolph's. Both are heiresses to the Hearst empire.

5. The Cox Family: $34.5 Billion, Media & Automotive

Much like the Hearst family, the Cox family started building their billions when James M. Cox purchased a newspaper, the Dayton Evening News, in 1898. Now, Cox Enterprises is a diversified communications, media and automotive services company with annual revenues of more than $17 billion from a brand portfolio that includes Autotrader, Kelley Blue Book and more. Its subsidiaries are Cox Communications, Cox Media Group and Cox Automotive. James C. Kennedy, grandson of the founder, is chairman of the board.

2. The Koch Family: $86 Billion, Energy & Diversified Holdings

Brothers William and Frederick Koch sold their shares of Koch Industries in 1983 for around $700 million — a reported $1 billion, according to Daily Finance — but spent years fighting for more from brothers Charles and David Koch. An unsuccessful lawsuit, spearheaded by William, sought $2 billion from the two brothers who maintained control of the company founded by their father in the 1930s.

The four brothers have reportedly laid the feud to rest. With more than $100 billion in annual revenue, Koch Industries is the country’s second-largest private company in the U.S., reports Forbes.

1. The Walton Family: $149 Billion, Retail

Six members of the Walton family own nearly 54 percent of shares in Wal-Mart Stores Inc., which has a current market capitalization of more than $200 billion. Wal-Mart has grown from a single store opened by Sam Walton in 1962 in Rogers, Ark., to become the world’s largest retailer, bringing in $482.2 billion in net sales this fiscal year from nearly 11,000 stores in 28 countries.
