MacArthur Foundation Grants 2026: Funding Opportunities, Priorities and How to Apply

The MacArthur Foundation Grants 2026 guide explains the foundation’s major funding programmes, grant amounts, priority areas, eligibility requirements and application process. Learn how the John D. and Catherine T. MacArthur Foundation supports transformative projects, journalism, climate solutions, criminal justice, Chicago-based initiatives and other programmes, including the $100 million 100&Change competition.

Background & Grant Opportunity

The John D. and Catherine T. MacArthur Foundation is one of the major philanthropic foundations supporting organisations and individuals working toward a more just, peaceful and sustainable world. According to the supplied research, the foundation had approximately $9.2 billion in total assets as of December 31, 2024 and provided about $352 million in grants and impact investments during 2024. Its geographic focus includes both the United States and international initiatives.

MacArthur organises its grantmaking around three broad approaches: Big Bets, which are time-limited investments designed to achieve transformative change; Enduring Commitments, which represent long-standing areas of interest; and Field Support, which strengthens important sectors and infrastructure.

For organisations searching for foundation grants, nonprofit funding, international development grants or social impact funding, understanding this approach is important. MacArthur does not operate like a conventional foundation where every programme accepts applications throughout the year.

The supplied research states that many of its project grants are generally awarded through relationships with programme officers and invitations, while unsolicited proposals may be reviewed but are rarely funded.

Major MacArthur Foundation Funding Programmes

MacArthur Fellows Programme

The MacArthur Fellows Programme, often referred to as the “Genius Grants,” provides unrestricted financial support to exceptionally talented and creative individuals.

The supplied source lists the award at $800,000 per fellow, paid over five years in quarterly instalments. Importantly, individuals cannot submit applications or nominations themselves. Fellows are selected through an anonymous nomination process involving external nominators.

This makes the programme fundamentally different from conventional scholarships and fellowships that applicants can directly apply for.

100&Change Competition

The 100&Change competition is one of MacArthur’s most notable funding opportunities. It offers a single $100 million grant to support a transformative solution to a critical social challenge.

The competition is open periodically rather than every year. According to the supplied information, eligible applicants include nonprofit and qualifying for-profit organisations, while individuals cannot apply independently. The review process can take approximately one year.

For organisations with an ambitious, evidence-backed solution capable of addressing a major social problem, 100&Change represents an exceptionally large potential funding opportunity.

Project Support Grants

MacArthur’s Project Support Grants are strategic investments that may provide approximately $50,000 to $850,000, with some major initiatives reaching the $1 million to $10 million range.

These grants can support general operating activities or specific projects, depending on the programme strategy.

However, applicants should understand that the foundation generally relies on programme officer invitations rather than open applications.

Expedited Grants

The foundation also has Expedited Grants, or X-Grants, which the supplied research lists at approximately $1,000 to $30,000.

These smaller awards can support activities such as meetings, convenings, knowledge-building initiatives and small research projects. They are also generally invitation-based and aligned with specific programme strategies.

Funding Priorities

MacArthur has supported a range of major social and environmental priorities.

Its Big Bets have included Climate Solutions, Criminal Justice, Local News, Nuclear Challenges and On Nigeria, although the supplied source notes that several of these initiatives were winding down or had concluded.

The foundation’s Enduring Commitments include the Chicago Commitment, particularly work involving racial equity, inclusion, culture and the arts, as well as Journalism & Media, with a focus on independent journalism and media in the United States.

MacArthur also supports impact investing and philanthropic-sector infrastructure through its Field Support activities.

Qualifications and Eligibility

Organisation Requirements

Eligibility varies according to the specific MacArthur programme. The supplied research indicates that Project Support Grants are generally strategic investments aligned with the foundation’s programme priorities rather than broadly available grants.

For the 100&Change competition, nonprofit and qualifying for-profit organisations may be eligible, while individuals are not eligible to apply independently.

What MacArthur Does Not Fund

According to the supplied source, MacArthur generally does not fund undergraduate, graduate or postgraduate scholarships or tuition assistance. It also generally does not provide grants to individuals, except through the MacArthur Fellows Programme.

The foundation also does not generally support political activities aimed at influencing specific legislation, annual fundraising drives, institutional benefits or ceremonial events.

Application Process

For regular Project Support Grants, organisations should first review the foundation’s programme guidelines and determine whether their work fits the relevant strategy.

The supplied research describes the typical process as:

Review the relevant MacArthur programme strategy and guidelines.
Establish alignment with the foundation’s priorities.
Engage with a programme officer where appropriate.
Prepare the required organisational and project documentation.
Submit a proposal when invited.
Allow the programme officer and foundation leadership to review the proposal.

Required materials can include a project narrative, proposed activities, leadership information, evaluation plans, sustainability information, organisational documentation, budgets and financial statements.

For 100&Change, the application process is competitive and includes multiple review stages before a final award is selected.

Additional Information

Organisations considering MacArthur funding should focus strongly on strategic alignment, equity, community leadership, evidence and long-term impact.

The supplied research highlights the importance of demonstrating that a proposed solution is feasible, durable and just. Strong applications should show that the organisation has the skills, relationships and capacity required to deliver the project while presenting realistic budgets and implementation plans.

MacArthur also places significant emphasis on the perspectives of communities closest to the problems being addressed. Clear communication, genuine commitments to equity and practical implementation are important considerations.

For grant seekers, the key lesson is that MacArthur Foundation funding is highly strategic rather than a general-purpose grant programme. Organisations should therefore research the foundation’s current priorities carefully before investing significant time in an application. The supplied research specifically notes that unsolicited proposals are reviewed but that very few are selected for funding.
