Open scholarly infrastructures — open-source systems and solutions supporting the discovery and sharing of research — are pivotal in ensuring access to knowledge and fostering innovation. In 2024, Invest in Open Infrastructure (IOI) mapped and analysed over $415M in grant funding for open infrastructure to uncover key trends and opportunities with the aim of driving more informed, strategic, and coordinated investment towards a healthy and resilient ecosystem of open infrastructure. The analysis shows a significant number of grant awards reference the use of open infrastructure but do not directly support their development. Further, while a substantial portion of grant funding supports research and development work of open infrastructures, a significant need for sustained operational support remains largely unaddressed. This presentation will highlight these funding trends and discuss their implications for the sustainability of open infrastructure. We will also discuss potential strategies to catalyze investments from a more diverse pool of stakeholders to foster a more robust funding ecosystem for open infrastructure.
