Our Goal

100&Change is our 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. We consider proposals from any field or problem area.  

Our Approach

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 that strive for transformational impact in areas identified by the Foundation’s board and staff. We recognize that we do not know it all and designed 100&Change to be agnostic with respect to field or problem area.

We are seek proposals that articulate both a problem and its solution. Competitive proposals will address a meaningful problem and provide a solution that is verifiable, durable, and feasible.

The Selection Process

We designed a selection process that is fair, open, and transparent. In the first round, evaluation panels of external judges review and score proposals using a common rubric. Based on those reviews, up to ten semi-finalists will be asked to provide further details about their proposals and to show engagement with targeted communities. The semi-finalists will also receive technical assistance from an expert team that will assess and advise plans for implementation of the proposed solution. From this group, a smaller number of finalists are selected. Selection of the final award recipient rests with MacArthur’s Board of Directors.

Information about the next round of the 100&Change competition will be made available in late 2018.

Measurement and Evaluation for Learning

Our measurement and evaluation of the grant will be determined after the selection process is completed. The recipient of the 100&Change grant will be asked to identify specific milestones to assess progress toward the implementation of the proposed solution and whether solution is having the anticipated impact.
