Following the wedding, Julia made her first New York society debut at the 1997 Met Gala, where she took the position of co-chairwoman along with Patrick McCarthy and Anna Wintour.

Unfortunately, in August 2019, David Koch died of cancer and Julia and their three children became the heirs of his majority stake in Koch Industries.

This suddenly propelled Julia Koch to the rank of “richest woman in the world.” In 2020, Forbes listed her in their 10 Richest Women in the World rundown.

The Success of Koch Industries

The Koch family owns Koch Industries, the second-largest privately held companies in the United States based on revenue, after Cargill.

It is likely one of the most influential companies that most people haven’t heard of.

Its subsidiaries operate in all kinds of manufacturing and refining, as well as distribution of chemicals, petroleum, energy, fiber, chemical technology equipment, finance, cloud computing, raw materials trading, and even investments.

David Koch joined the business as a technical services manager, working alongside the Koch family, i.e. his brothers Charles, Bill, and Frederick. This business was founded by their father Fred C. Koch in 1940. When he died in 1967, the majority interest in the business was split amongst his four sons.

In 1979, David Koch founded an office in New York City and, that same year, he became the president of Koch Engineering, his own division.

In 1983, after a brutal legal battle within the Koch family, the stake of Bill and Frederick Koch were bought by Charles and David for $1.1 billion, making them the two majority owners of the company with a 42% stake each. The legal disputes that followed lasted two decades and gave birth to endless controversies – as well as some bestselling novels.

Today, the business is absolutely booming with an annual revenue tops $125 billion.

It employs 122,000 people in 60 countries and operates with several businesses including:

• KBX
• Flint Hills Resources
• Guardian Industries
• Invista
• Georgia-Pacific
• Infor
• Koch Engineered Solutions
• Koch Minerals & Trading
• Koch Investments Group
• Molex

Today, Julia Koch serves on the board of directors at the company and is a co-owner of Koch Industries, replacing her husband in the role.

Philanthropy

Koch now serves as president of the David H. Koch Foundation. She also serves on the board of the Memorial Sloan Kettering Cancer Center.

The David H. Koch Foundation has made grants of over $200 million for medical research, science, education, arts, public policy, and more. As the president, Julia oversees her husband’s contributions and has chaired events for the Food Allergy Initiative, the American Ballet Theatre, and the Memorial Sloan Kettering Cancer Center, among others.

She has also funded the Koch Institute for Integrative Cancer Research at MIT, working on Nano-based drugs, precision medicine, and more.

While her husband was still alive, the couple made donations to the Lincoln Center, the Smithsonian Museum of Natural History, and the Metropolitan Museum of Art, among others.

They also donated $10 million to the Stanford Children’s Hospital to study food allergies, and another $10 million to the Mount Sinai Medical Center.

Julia Koch Net Worth: Other Investments

Despite her wealth, Julia Koch is a very private person, which means that there is very little public information about her personal life or investments.

However, in recent months, she was announced her intentions to buy a minority stake in BSE Global, which owns the Brooklyn Nets NBA team as well as the Barclays Center.

The team remains in discussions to sell the stake to Koch. If the deal is to be completed, Koch would acquire around 10% of BSE Global, the parent company of the Nets and the WNBA’s New York Liberty. The valuation could be as much as $4.8 billion.

Real Estate Assets

While her late husband was still alive, the Koch family lived in an apartment at 1040 Fifth Avenue for years.

This was the former home of the First Lady Jacqueline Kennedy Onassis and they bought it for $9.5 million. In 2004, they moved to a duplex at 740 Park Avenue.

David Koch bought this apartment from the Japanese government for $17 million, and the home was previously used to house their permanent representative to the United Nations.

Following this purchase, in 2018, the couple bought a townhouse with eight bedrooms in Manhattan for $40.25 million.

In 2022, following her husband’s death, Julia Koch put the Park Avenue apartment up for sale. After the sale, she bought a pair of East Side co-ops in Manhattan for a whopping price of $101 million, as well as a $75 million historic home in the Hamptons on Billionaire Lane.

That’s not even close to everything the family owns in real estate. Before the marriage, David Koch spent $7.5 million on a seven-bedroom mansion in Southampton, a property that is now worth at least $40 million and most likely still in the family’s ownership.

Koch is also the owner of a home in Palm Beach worth $10.5 million in 1998 and worth at least $70 million today, which she usually visits in the winter months.
