Warren Buffett has upended one of the world’s largest philanthropic pipelines, halting his long‑running multi‑billion‑dollar support for the Bill & Melinda Gates Foundation after growing unease over Bill Gates’s past relationship with Jeffrey Epstein.

Early revelations and growing concern

Over recent years, detailed reporting on Microsoft co‑founder Bill Gates’s ties to convicted sex offender Jeffrey Epstein intensified scrutiny of Gates’s judgment and associations.¹ As these revelations accumulated, they began to weigh on Buffett, a long‑time friend and philanthropic partner of Gates.

Buffett reconsiders his giving strategy

By mid‑July 2026, Buffett, the chair of Berkshire Hathaway, had decided to alter his personal charity plans. He announced that his annual donation of roughly $6 billion in Berkshire stock would no longer be directed to the Bill & Melinda Gates Foundation, breaking with a pattern that had helped make the foundation one of the largest in the world.²

According to reporting on Buffett’s thinking, the shift followed the fresh focus on Gates’s Epstein links, which he found troubling enough to reassess the partnership.²

Public characterization of Gates–Epstein ties

As he explained the change, Buffett went further in his public characterization of the issue, describing Bill Gates’s relationship with Epstein as “distasteful.”¹ At the same time, he reportedly acknowledged that he could “picture” himself making a similar error in judgment when choosing associates, signaling criticism of the association while expressing some empathy for human fallibility.¹

Implications and diverging interpretations

Supporters of the move see Buffett’s decision as a high‑profile stand on ethical partnerships in philanthropy, arguing that major donors must distance themselves from any taint linked to Epstein.² Others interpret his remarks about being able to imagine a comparable mistake as an attempt to strike a nuanced tone—condemning the relationship yet resisting a full personal rupture with Gates.¹

The immediate effect is clear: a major funding stream for the Gates Foundation has been cut off, and one of modern philanthropy’s most influential alliances has been fundamentally reshaped.
