MacKenzie Scott has donated more than $19 billion—but it’s barely made a dent in her net worth because of the power of Amazon shares

Scott came to much of her fortune through her connection to Bezos. (They divorced in 2019.) During her marriage, she played a key role in Amazon’s founding and early operations, including helping with business plans and contracts. Upon their divorce, she received roughly a 4% stake in Amazon, which amounted to roughly 139 million shares at the time. 

Since then, she’s reduced her stake by about 42%, selling or donating about 58 million shares, worth around $12.6 billion as of late 2025. She’s still worth more than $35 billion today, despite having donated $19.25 billion through her philanthropic platform Yield Giving, which she founded in 2022. The organization has donated to thousands of organizations, focused on issues including DEI, education, disaster recovery, and more.

Although Scott continues offloading Amazon shares, her wealth continues to grow. Year-to-date, she’s added $923 million to her net worth, according to the Bloomberg Billionaires Index. Since November 2020, Amazon share prices have jumped more than 45%. 

In 2020, Bezos made the largest charitable donation of the year, a $10 billion gift to launch the Bezos Earth Fund, aimed at addressing climate change. He’s also donated about $790 million to various environmental groups through the fund, $110 million through Day 1 Families Fund to support homeless families and $120 million to his tuition-free preschool network, Bezos Academy. Also, in 2024, he completed a $200 million pledge to Smithsonian for renovations and a new learning center. 

But his lifetime giving amounts to just $4.1 billion, according to Forbes’ America’s Most Generous Philanthropists 2025 list published in April. Considering the man is worth $264 billion, that’s just 1.6% of his net worth, whereas Scott has given 36% of her net worth, according to Forbes. 

To be sure, Forbes counts “lifetime giving” as money that has already been donated, and not funds that are just parked in a foundation for now. The list showed Scott is the fifth-most generous philanthropist, behind Warren Buffett, Bill Gates and Melinda French Gates, George Soros, and Michael Bloomberg. 

MacKenzie Scott’s major gifts this year

In a matter of months, Scott donated hundreds of millions of dollars to organizations focused on DEI, education, and disaster recovery. Just a sample of her largest recent gifts include: 

MacKenzie Scott’s giving style

Scott’s philanthropic style is considered unique because she makes gifts unrestricted, meaning the organizations can choose how to use the donations. 

“Unlike traditional funding processes that often involve lengthy applications, specific restrictions, and reporting requirements, her style empowers organizations like ours to determine how best to direct funds quickly and innovatively to address pressing issues,” Noni Ramos, CEO of Housing Trust Silicon Valley, told Fortune in late 2024, when her organization received a $30 million gift from Scott. 

Scott has also been particularly focused on DEI, education, and disaster relief recently, three areas where the Trump administration has made major cuts. This could suggest Scott’s philanthropy is trying to fill the void from the White House. 

She stands behind the idea Americans should “recognize and celebrate our role as active participants in the co-creation of our communities,” Scott wrote in an Oct. 15 post on her Yield Giving site. 

“The potential of peaceful, non-transactional contribution has long been underestimated, often on the basis that it is not financially self-sustaining, or that some of its benefits are hard to track,” she wrote. But what if these imagined liabilities are actually assets? What if these so-called weaknesses foster the strengths upon which the thriving (or even survival) of our civilization depends?”
