We believe every person’s life has intrinsic value regardless of where they were born. Across our funds that focus on global health and development, we support work that improves the lives of the world’s poorest people — who often live on a few dollars a day and lack access to basic necessities like clean water, sanitation, or healthcare. The work we fund ranges from reliable, cost-effective interventions, like distributing medication , to more ambitious interventions like advocating for policy change to improve economic conditions .
Most of this fund’s spending supports organizations recommended by GiveWell , with whom we have a close relationship . GiveWell looks for opportunities with a strong evidence base, successful track record, and low risk of failure (relative to our usual hits-based giving approach). Its previous recommendations include charities working on:
Malaria control: distributing bednets and antimalarial medicine in high-prevalence areas.
Clean water access: providing in-line chlorination technology to rural villages.
Vaccination programs: supporting work to develop and distribute life-saving vaccines, and to help parents keep up with vaccination schedules.
This fund also makes grants in areas recommended by our cause prioritization researchers where we may want to launch a fund later. (We followed this process for our Global Growth Fund .)
This fund is not currently accepting unsolicited proposals.

Allocating $175M to GiveWell’s Recommendations for 2026
In October 2023 , we committed $300 million over three years to GiveWell’s evidence-backed, cost-effective recommendations in global health and development. We recently decided to renew that funding early and increase it, committing an additional $175 million for 2026. This funding adds to the more than $1 billion we have previously committed to GiveWell’s recommendations.
