Big Problems Require Bold Solutions

Solving society’s biggest problems is not easy, but we believe solutions are possible. 100&Change is our global competition for a proposal that promises measurable progress toward solving a critical social challenge. We will award a single $100 million grant to help make that solution a reality. We are open to organizations working in any field, anywhere in world. Are you ready to solve a problem?

How to Get Ready

We are offering several tools and resources to help organizations get ready to apply for 100&Change. Our goal is to provide this information so you can better plan and prepare to participate in the next round of the competition.

Is Your Organization a Good Fit?

We created an organizational readiness tool to help you determine whether your organization is ready to compete in 100&Change. This tool was designed to help you understand characteristics of the most competitive organizations and proposals. We encourage you to use this tool to consider how well-suited your organization(s) and/or proposal are for 100&Change.

Preview the Application

We are offering a sample of the application, so you can begin crafting a proposal. We encourage you to read the application questions, so you can start considering what proposal content you want to gather should you decide to submit a proposal when the online competition portal opens in April. Please use the organizational readiness tool to help inform your likely competitiveness for 100&Change.

Please note that this is a static and partial version of the 100&Change application. This is not the actual application, and MacArthur reserves the right to modify or change the application in whole or in part.

All applications must be submitted via the online portal to be considered eligible. Once the competition officially launches, you can register and access the full and interactive version of the application.

Webinars for Applicants

We invite you review our webinar series, “Think Big & Communicate Clearly: Bold Ideas for Philanthropy,” which was designed to help 100&Change applicants think about the depth, breadth, and impact of their work. This series was previously offered to organizations that had their proposals evaluated in our inaugural 100&Change competition.

Scoring Process

Every valid application will receive scores and comments from peer reviewers and five members of our "wise head" panel. Scores are normalized to ensure a level playing field for everyone. Please review carefully the traits the judges will use to score your application.


Does the proposal describe an urgent problem worth solving, and will the solution have a transformative impact? Is the proposal sufficiently ambitious either in its progress toward a solution; the number of direct beneficiaries served; the size of the geography served; or intensity of impact on a small but vulnerable population or geography?


Does the proposal present evidence that the solution or critical components of it have previously yielded practical and concrete results? Does the evidence suggest that the solution can be adapted to other contexts, such as expanding to new populations or geographies, or to reach a greater number of people over time, and still retain its effectiveness?


Does the team have the skills, capacity, relationships, and experience to deliver its proposal? Do the budget and project plan represent a realistic understanding of a successful implementation of the solution? Does the proposal outline a mitigation plan for risks associated with changes in key personnel and political, market, or social environments?


Will the solution have a sustained impact? Does the solution either expect to solve a problem in 5 years or create a pathway to solving the problem over time? Will the project elicit support from other sources – private, philanthropic, or public? Has the team advanced a clear, cogent, and compelling vision for the future?
