"I have no use for money," Bill Gates told The Telegraph in 2013. But he often speaks of his philanthropic giving and healthcare investments.

A grant from Bill and Melinda led to the creation in 2003 of Amyris, a synthetic biology company that originally produced precursors to malaria drugs and hydrocarbon-based biofuel but also uses the technology for things like fragrances, skincare, and sweeteners. The company filed for Chapter 11 bankruptcy in 2023.

In November 2017, Gates invested $50 million into Alzheimer's research.

He continued these efforts in 2018 by investing $30 million with a group of investors into the Diagnostics Accelerator, a "venture philanthropy" fund to diagnose Alzheimer's earlier.

Gates is frequently named among the most generous philanthropists in the US by The Chronicle of Philanthropy.

Gates has vowed to give away most of his fortune through the Giving Pledge, which he helped launch in 2010.

Gates and his former wife have pledged about $2 billion to defeat malaria, donated more than $50 million to fight Ebola, and pledged $38 million to a Japanese pharmaceutical company working to create a low-cost polio vaccine.

During the pandemic, their foundation announced a 5-year, $1.6 billion commitment to Gavi, the Vaccine Alliance, to deliver vaccines in the world's poorest countries.

The Gates Foundation also gives toward education through its $1.6 billion initiative the Gates Millennium Scholars Program.

The foundation has made $77.6 billion in grant payments from its inception through Q4 2023, and Bill and Melinda's total giving to the foundation during that time period totals $59.5 billion.

Its 2024 budget is $8.6 billion, and the foundation is targeting a $9 billion yearly budget by 2026.
