Bill and Melinda Gates are divorcing after 27 years of marriage

The foundation said in a statement that the Gateses would remain co-chairs and trustees and that no changes were expected at the organization.

“They will continue to work together to shape and approve foundation strategies, advocate for the foundation’s issues and set the organization’s overall direction,” the statement said.

Even so, the divorce will create new questions about the fate of the Gates fortune, much of which has not yet been donated to the Gates Foundation. Bill Gates, 65, is one of the richest people in the world, worth an estimated $124 billion, according to Forbes. The Gateses have been married for 27 years and have three children, ages 18 to 25.

“The Gates Foundation is the most important and influential philanthropic entity in the world today,” said Rob Reich, a professor of political science at Stanford University. “The divorce may have huge repercussions for the foundation and for its work across the globe.”

With 1,600 staff members in offices around the world, the Gates Foundation gives away roughly $5 billion each year in areas like global public health and development. Over more than two decades, the foundation has spent billions to push vaccines to the developing world, working with pharmaceutical executives to transform the market.

The foundation tapped its expertise and relationships to play a significant role in formulating the global response to the pandemic, investing early in vaccine candidates and helping shape COVAX, the global initiative organizing the purchase of vaccines for 92 poor countries and dozens of other nations.

The Gateses have won great praise for their efforts, but the foundation has also received a fair share of criticism for working to protect the intellectual property rights of private companies. That has come into focus now more than ever as many national governments have pressed for open access to COVID vaccines to put an end to the pandemic.

“Bill and Melinda Gates helped pioneer big philanthropy in its present form,” said David Callahan, founder of the website Inside Philanthropy. “Everything has been outsized.”

While the Gateses did not provide details of how they would structure their finances, they are believed to have a prenuptial agreement. The Gateses are the largest owners of farmland in America and have vast investments though Cascade Investment, which manages Bill Gates’ personal wealth and owns large stakes in the Four Seasons hotel chain, the Canadian National Railway and AutoNation, the country’s largest chain of car dealerships, among other companies. The family’s homes and properties include a 66,000-square-foot Washington state mansion, which features amenities such as a trampoline room, a screening room and a multiroom library filled with rare documents and artifacts.

Callahan said Melinda Gates, 56, could assume even more influence in the years ahead.

She already has her own firm, Pivotal Ventures, which she has used to invest in issues related to women’s economic empowerment. (Bill Gates has his own private office, Gates Ventures, for pursuing interests outside the foundation.) Should she receive a portion of Bill Gates’s Microsoft holdings, she could set up a new foundation or make direct gifts to other causes she supports.

“You could imagine Melinda Gates being a much more progressive giver on her own,” Callahan said. “She’s going to be a major force in philanthropy for decades to come.”

In 2019, Jeff Bezos, the founder of Amazon, and his longtime wife, MacKenzie Scott, divorced. Scott received Amazon shares worth $36 billion at the time and immediately set about giving away billions of dollars in direct grants to a variety of progressive organizations.

The Gateses have faced relationship struggles over the past several years, two people close to them said. There were several times when the relationship neared collapse, but they worked to keep it together, the people said. Bill Gates decided to step down from the boards of Microsoft and Berkshire Hathaway, in part, so he could spend more time with his family, these people said.

“When he was having trouble making the decision about getting married, he was incredibly clear that it was not about me, it was about ‘Can I get the balance right between work and family life?’” Melinda Gates said in an interview in 2019 in The Sunday Times of London. “And, believe me, I can remember some days that were so incredibly hard in our marriage where you thought, ‘Can I do this?’”
