ABOUT COEFFICIENT GIVING

Coefficient Giving (formerly Open Philanthropy https://coefficientgiving.org/research/open-philanthropy-is-now-coefficient-giving/) is a philanthropic funder and advisor. Since 2014, we’ve directed over $5 billion in grants as part of our mission to help others as much as we can with the resources available to us. We work with a range of donors who share our commitment https://coefficientgiving.org/our-approach/ to cost-effective, high-impact giving. Our current funds include Science and Global Health R&D https://coefficientgiving.org/funds/science-and-global-health-rd/, Navigating Transformative AI https://coefficientgiving.org/funds/navigating-transformative-ai/, Biosecurity & Pandemic Preparedness https://coefficientgiving.org/funds/biosecurity-pandemic-preparedness/, Abundance & Growth https://coefficientgiving.org/funds/abundance-and-growth/, Farm Animal Welfare https://coefficientgiving.org/funds/farm-animal-welfare/, and more https://coefficientgiving.org/funds/. In 2025, we recommended more than $1 billion to high-impact causes.

We’re proud of our track record:

- We jump-started the field of AI safety and security https://coefficientgiving.org/research/ai-program-update-navigating-transformative-ai/ and have played a vital role in addressing other existential threats, such as mirror bacteria https://www.mbdialogues.org/.

- Our grants to evidence-backed global health programs have saved over 100,000 lives, and our farm animal welfare grants have improved the lives of over 3 billion animals.

- We supported late-stage clinical trials for the R21 malaria vaccine, now being scaled to protect millions of kids globally https://www.nature.com/articles/d44148-025-00245-8#:~:text=Uganda%20is%20at%20the%20forefront,M%20vaccine%20to%20105%20districts..

- We were the earliest major funder of the YIMBY movement to build more housing. Our grantees have led the charge on major wins like City of Yes https://www.nyc.gov/mayors-office/news/2024/12/mayor-adams-governor-hochul-speaker-adams-celebrates-passage-most-pro-housing-proposal-in in New York, and SB 79 https://www.gov.ca.gov/2025/10/10/governor-newsom-builds-on-this-years-historic-housing-reforms-signs-legislation-to-accelerate-housing-and-affordability/ in California, which will enable hundreds of thousands of new housing units.
