Description
The MacArthur Foundation's Impact Investments program is dedicated to building the field of impact investing by providing flexible, patient, and risk-tolerant capital to address pressing social and environmental challenges worldwide. Through annual field-support grants and special initiatives, the program supports nonprofits, social enterprises, funds, public agencies, and quasi-governmental entities working to advance equity, inclusive economic growth, and climate solutions. The initiative aims to fill critical gaps left by conventional capital markets, mobilize additional resources, and foster systemic change aligned with the United Nations’ Sustainable Development Goals.
Current priorities for field-support grants include strengthening the catalytic capital ecosystem, building field infrastructure, supporting impact integrity and policy, and advancing equity and inclusion within the investing and finance sectors. Special initiatives such as the Catalytic Capital Consortium and Benefit Chicago further extend the program's reach both locally and globally.
