Sue Desmond-Hellmann announced in December 2019 that she would leave her role as CEO of the Bill & Melinda Gates Foundation. Mark Suzman, a longtime foundation executive, became CEO on February 1, 2020. The “$47 billion” in contemporary headlines referred to a reported $46.7 billion in foundation assets in 2019—not its current endowment.
Who succeeded Sue Desmond-Hellmann, and when?
The Gates Foundation announced the transition on December 5, 2019. Bill and Melinda Gates appointed Mark Suzman, then president of Global Policy & Advocacy and chief strategy officer, as CEO effective February 1, 2020. The foundation’s announcement described Suzman as an internal successor who had joined the organization in 2007.
Suzman had held senior roles in policy, advocacy and strategy. Before the foundation, he worked at the United Nations and as a Financial Times correspondent, according to the announcement. GeekWire reported that Desmond-Hellmann recommended him as part of succession planning.
Why did Desmond-Hellmann leave?
Desmond-Hellmann said she was leaving full-time work after deciding she could not meet the role’s demands while caring for her health and family. “I felt I could no longer be the CEO the foundation needs and deserves at this vital time,” she said in the foundation’s announcement. She also called it “the toughest decision of my career.”

She joined the foundation in 2014 after serving as chancellor of the University of California, San Francisco. An oncologist, she had treated and researched AIDS-related cancer and helped lead development of Herceptin at Genentech. The foundation credited her tenure with establishing the Gates Medical Research Institute and launching its U.S. Economic Mobility and Opportunity strategy.
What did the “$47 billion” figure mean?
The figure was a rounded version of GeekWire’s reported $46.7 billion in foundation assets in 2019. It describes the scale reported at that time, not the foundation’s current endowment. Later figures use different dates and measures, so they should not be read as a directly comparable, audited growth series.
| Figure | What it measures and when |
|---|---|
| $46.7 billion | Foundation assets reported by GeekWire in 2019; rounded to $47 billion in its headline. |
| $89 billion | Gates Foundation Trust endowment as of December 31, 2025, according to the foundation’s financial information. |
| $92 billion | Trust endowment as of June 30, 2026, identified by the foundation as unaudited. |
| $8.47 billion | Total charitable support in 2025, including operations, grants and direct charitable contracts, but excluding program-related investments. |
These measures are not interchangeable. Endowment is not the same as a year’s charitable support, and neither is the same as donor contributions. The foundation reports $47.9 billion in Warren Buffett giving from 2006 through 2025; that is cumulative giving, not the endowment balance.

The foundation’s current financial information still identifies Mark Suzman as CEO. In 2026, the foundation announced a board-endorsed annual payout of $9 billion, with approximately 70% of its budget allocated to global health goals. That planned payout is a separate measure from the endowment and from the 2025 charitable-support total.

Bill Gates said in 2025 that the foundation would close permanently on December 31, 2045. He projected more than $200 billion in giving from 2025 through 2045, including the endowment balance and his future contributions; he said the amount would depend on markets and inflation. It is a projection, not a guaranteed total. Suzman described the deadline as an opportunity to focus on outcomes for the people the foundation serves.
