--- ## 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. --- ## Due Dates - June 2026 (anticipated/projected): Annual field-support grants application deadline *All dates are projected based on the annual cycle; check the program page for updates.* --- ## Funding Amount - The program awards approximately $5 million in grants annually. - Recent representative grants typically range from $300,000 to $2,000,000. - Funding may support general operations, special initiatives, or capacity-building projects. --- ## Eligibility - Eligible applicants include: - Traditional nonprofits - For-profit enterprises - Special-purpose funds - Public agencies and quasi-governmental entities - Grants and investments are global in scope, supporting both U.S.-based and international organizations. - The program is not currently accepting unsolicited proposals; prospective applicants are encouraged to contact the program team to discuss alignment and ideas. --- ## Application Process - The MacArthur Foundation is not accepting unsolicited proposals at this time. - Interested organizations should reach out to the program team to share new ideas or perspectives. - Registered users may submit ideas or manage applications through the [MacArthur Fluxx portal](https://macfound.fluxx.io/user_sessions/new). - For more information on guidelines and current priorities, review the [Investment and Grant Guidelines](https://www.macfound.org/programs/field-support/impact-investments/grant-guidelines). --- ## Additional Information - Impact investments may take the form of debt, equity, or guarantees and may be structured as Program-Related Investments or Mission-Related Investments. - Grants support field-building activities such as knowledge-sharing, policy development, advancing standards, and fostering inclusion in the impact investing ecosystem. - Special focus areas include climate solutions, community development, Indigenous autonomy, local news, and journalism/media. --- ## External Links - [Impact Investments Program Overview](https://www.macfound.org/programs/field-support/impact-investments/) - [Grant Guidelines](https://www.macfound.org/programs/field-support/impact-investments/grant-guidelines) - [Strategy and Priorities](https://www.macfound.org/programs/field-support/impact-investments/strategy) - [Recent Grants](https://www.macfound.org/grants/?program=102206&funding-type=Grants&program=102206) - [Catalytic Capital Consortium](https://www.macfound.org/programs/field-support/impact-investments/catalytic-capital-consortium/) - [MacArthur Foundation Grants Info for Grantseekers](https://www.macfound.org/grants/info-for-grantseekers) --- ## Contact Information | Purpose | Contact Details | |------------------------|----------------------------------------------------------| | General Inquiries | [Contact form](https://www.macfound.org/about/contact-us) | | Program Team (Ideas) | nbarksdale@macfound.org | | Grants Info | 4answers@macfound.org | | Phone | +1 312-726-8000 |
