Stephen Schwarzman built one of the world’s largest private-equity firms, banked some of the biggest paydays in modern finance, and committed more than $1 billion to charity over his lifetime.
And the Blackstone cofounder and CEO traces the roots of his charitable giving to observing his grandfather.
“I remember being a young boy and watching my grandfather pack prosthetics, wheelchairs, clothes, books, and toys to send to children in Israel every month,” Schwarzman wrote in his 2020 Giving Pledge letter. “When I asked him why, he explained that it was not only his obligation, but also his privilege to help others in need.”
The Giving Pledge is a commitment for ultrawealthy individuals to give away the majority of their wealth; other signatories include MacKenzie Scott, Warren Buffett, Mark Zuckerberg, and more.
Schwarzman, who has donated at least $1 billion over his lifetime, also highlighted his father, who ran a store in Philadelphia, regularly extending credit to newly arrived immigrants.
“‘Buy what you need,’ he would tell them, and ‘pay me when you can,’” Schwarzman wrote. “These powerful memories have helped shape who I am and serve as a lasting reminder of the responsibility I have to uphold my family’s commitment to giving.”
Stephen Schwarzman’s $45 billion fortune and $1 billion philanthropy
Schwarzman cofounded Blackstone in 1985 with Peter G. Peterson with just $400,000 in seed capital, and the firm now manages more than $1.3 trillion in assets. Today, Schwarzman’s net worth sits around $45 billion, according to the Bloomberg Billionaires Index. In 2025, Schwarzman took home $1.24 billion, with the bulk of it from dividends on his roughly 20% stake in Blackstone, against a comparatively modest $350,000 salary.
His philanthropy has matched his interest in tackling complex, structural challenges. Schwarzman’s foundation coins itself as one of the world’s largest donors to educational institutions. Some of his namesakes include the Schwarzman College of Computing at MIT, seeded by a $350 million gift in 2018; a £150 million gift to the University of Oxford to create a new humanities center housing an institute for ethics in AI; a student center at Yale, his undergraduate alma mater, backed by $150 million; and Schwarzman Scholars, a selective fellowship program at Tsinghua University in Beijing. He and his wife, Christine Hearst Schwarzman, are also among the largest donors to the U.S. Catholic school system, he wrote in his Giving Pledge letter. He also donated $100 million for the renovation of the New York Public Library.
In his pledge letter, Schwarzman also pointed to artificial intelligence as a defining concern.
“I saw an urgent need to ensure our society is prepared for the changes to come, which is why I have funded two large-scale programs related to AI, both of which incorporate a focus on AI’s ethical and policy considerations,” he wrote.
Schwarzman’s plan to build a top-10 philanthropic foundation focused on AI
That theme is now driving his new philanthropic commitment.
Schwarzman is reportedly planning a major expansion of the Stephen A. Schwarzman Foundation, according to The Wall Street Journal. The foundation held $65 million in assets as of 2024, according to the report. His new aim is to build a top-10 U.S. philanthropy focused on AI and education. According to an internal report obtained by WSJ, Schwarzman, 79, plans to transfer a “substantial majority” of his fortune to his foundation upon his death.
Despite the massive scale of his philanthropy, Schwarzman framed his motivation for giving this way in his Giving Pledge letter: “My philanthropy has brought a tremendous sense of joy and meaning to my life and I anticipate I will find more ways to give back during my lifetime.”
