100&Change

The John D. and Catherine T. MacArthur Foundation, commonly known as the MacArthur Foundation, is a prominent philanthropic organization based in Chicago, Illinois. Founded in 1970, the Foundation is dedicated to supporting creative individuals and effective institutions committed to building a more just, verdant, and peaceful world. The Foundation’s work spans several key areas, including climate solutions, criminal justice reform, local journalism, and global security. One of its signature initiatives is the MacArthur Fellows Program, often referred to as the "Genius Grant," which awards $800,000 in no-strings-attached funding to extraordinarily talented and creative individuals across various fields. Another significant initiative is the 100&Change competition, where the Foundation awards a $100 million grant to a single project that addresses a critical global problem. This competition runs every four years and is designed to fund solutions that are impactful, evidence-based, and sustainable. The Foundation also emphasizes technology’s role in public interest, supporting initiatives that advance equity and justice in the digital age. In response to the COVID-19 pandemic, the MacArthur Foundation launched the Equitable Recovery program, committing $125 million to address structural racism and improve public health and housing systems.
