A competition for a $100 million grant to fund a single proposal that promises real and measurable progress in solving a critical problem of our time.


Some problems cannot be solved by grants of the size that foundations typically provide. By funding at a level far above what is typical in philanthropy, we can address problems and support solutions that are radically different in scale, scope, and complexity. $100 million is a large enough sum to focus on a serious problem and its solution in a meaningful and lasting way. We hope that 100&Change can inspire a conversation about solutions and about how we can solve some of our most significant problems.

The openness of 100&Change is a counterbalance to the Foundation’s Big Bets, which strive for transformational impact in areas identified by the Foundation’s Board and Staff. In contrast, we designed 100&Change to be agnostic with respect to the field or problem area.

We seek proposals that articulate both a problem and its solution. Competitive proposals will address a significant problem and provide a solution that is impactful, evidence-based, feasible, durable, and just.

Selection Process

We designed a selection process that is fair, open, and transparent. Once the application period closes, Lever for Change Staff will work to review each 100&Change submission to ensure it meets the requirements and rules before advancing to the next stage. During the participatory review process, applicants within the same domain will score and provide feedback on each other’s proposals using our established criteria. Our Wise Head Panel of external judges will then review and score submissions using the same criteria and scoring rubric. MacArthur's Board of Directors will then select up to five finalists. Over the next several months, the finalists will work with an expert team to strengthen their proposals, present a preliminary plan for monitoring and evaluation and learning, and show authentic engagement with communities of interest before submitting revised project plans.

The selection of the final award recipient rests with MacArthur’s Board.

Evaluation for Learning

MacArthur contracted with Abt Associates to conduct an evaluation of the application and selection processes of the inaugural 100&Change competition. The evaluation was designed to identify areas that worked well and should be preserved for future rounds of the competition and those that could be improved. Data collection included interviews and focus groups with a range of 100&Change stakeholders to understand their unique experiences and perspectives.
