John D. and Catherine T. MacArthur Foundation
At a glance
This funder does not accept unsolicited applications. The foundation chooses the organisations it funds itself.
Key takeaways
- This is an invitation-only funder that does not accept unsolicited requests, so look for clear signals of fit before approaching it.
- Its stated focus is global, U.S. and Chicago priorities, covering climate change, criminal justice reform, revitalising local news in the U.S., artificial intelligence, the well-being of Native communities, and empowering young people in Nigeria, alongside commitments to journalism and democracy and to the strength and vitality of Chicago.
- Most grants to organisations are modest: about 8 in 10 of its 3,678 grants to organisations fall between $450 and $500,000, with a median grant of $85,000, so a request in that range is realistic, while the single $32,500,000 grant to The Miami Foundation, an organisation it funds every year that regrants to others, is not typical of what a new applicant should expect.
- A high share of its support is repeat giving - 77% of grant dollars to organisations went to organisations it had also funded in recent prior filings - suggesting it favours sustained relationships, so be prepared for ongoing engagement rather than a single approach.
- It will not fund political activities or attempts to influence legislation, scholarships or tuition assistance, unsolicited grants to individuals outside its Fellows Program, annual fundraising drives, institutional benefits, honorary functions, or similar projects, so check these exclusions before applying.
