For the first time in two decades, Warren Buffett did not write a cheque to the Bill & Melinda Gates Foundation. According to Business Insider Africa, the 95-year-old Berkshire Hathaway chairman distributed nearly $6 billion in Berkshire Class B shares among four family-run foundations instead — the largest single tranche going to the Susan Thompson Buffett Foundation, which received roughly 9 million Class B shares valued at approximately $4.4 billion.
The break with tradition dates to early 2026, when emails surfaced showing contact between Jeffrey Epstein and Gates Foundation staff. The foundation launched an external review shortly after, and Buffett has indicated he is waiting for that review to conclude before deciding whether to resume his giving. Since he first began donating to the Gates Foundation in 2006, Buffett has been among its most consequential benefactors, transferring tens of billions of dollars in Berkshire stock over the years.
The governance backdrop compounds the funding shift. Melinda French Gates, who co-chaired the foundation alongside Bill Gates, officially stepped down in 2024 following the couple's 2021 divorce. The foundation is therefore navigating both a leadership transition and a reputational review simultaneously — hardly ideal timing given the scale of the spending commitment Gates has just publicly reaffirmed.
That commitment is substantial: in May 2025, Gates announced a 20-year, $200 billion plan, with the majority of those funds earmarked for Africa. He confirmed the pledge during an address at the African Union, framing the initiative around three concrete targets to be achieved by 2045 — ending preventable maternal and infant deaths, eradicating major infectious diseases, and lifting millions of people out of poverty. The foundation has also announced it will cease operations entirely once that 2045 mission concludes.
The Africa strategy centres on partnering directly with governments to strengthen primary healthcare infrastructure, and Gates has pointed to artificial intelligence and digital health tools as force-multipliers for under-resourced systems across the continent. The ambition is significant: $200 billion deployed over 20 years works out to an average of $10 billion annually, a figure that dwarfs the annual health budgets of most African governments individually.
The immediate arithmetic problem is visible. Buffett's annual contributions have historically represented a meaningful share of the foundation's incoming resources. Losing roughly $6 billion in a single year — even temporarily — creates a gap that cannot be easily backstopped. Gates has personal wealth of his own to deploy, and the foundation retains an existing endowment, but the Epstein review and the loss of Buffett's giving introduce real uncertainty into the foundation's near-term capital planning at the exact moment it is trying to accelerate Africa-focused disbursements.
For African health ministries and civil society organisations that have built programme pipelines around Gates Foundation commitments, the optics of donor instability matter as much as the numbers. Governments that have aligned national health strategies with expected Gates funding — on malaria eradication, maternal health, or vaccine delivery — will be watching the external review closely. Any prolonged pause in Buffett's giving, or a permanent redirection, would require the foundation to either draw down reserves more aggressively or slow its Africa ramp-up.
There is also a broader signal here for philanthropic capital flows into Africa. The Gates Foundation remains one of the few non-governmental funders operating at a scale that can move national health indicators. If governance controversies constrain that scale, it reinforces the case African policymakers have long made for reducing dependence on any single external donor — and for building domestic revenue bases capable of funding health systems independently.
Why it matters: A $200 billion, 20-year pledge to Africa is only as credible as the institution behind it. With Buffett's $6 billion annual contribution now on hold pending an Epstein-related review, and the foundation's co-founder gone since 2024, the Gates Foundation enters its most consequential phase of Africa spending with its internal governance under scrutiny — a risk that African health planners and finance ministries cannot afford to ignore.
