In January, Frontiers hosted a discussion forum for United States-based research funders to explore the challenges and opportunities funders face in supporting and incentivizing open science. Representatives from the Gordon and Betty Moore Foundation, the Bill and Melinda Gates Foundation, the National Institutes of Health, the Howard Hughes Medical Institute, and the Alzheimer’s Association came together to address three major topics:

• The role of funders in leading open access

• Prominent, practical, and promising examples of open access

• New initiatives to define and shape open access
