Key takeaways

  • If your work sits within criminal justice, health care, infrastructure, public finance, or higher education and career pathways, the foundation asks that requests align with those core areas, so a project outside them is unlikely to fit.
  • About 8 in 10 of its grants fall between $19,500 and $550,000, and half are about $130,000 or less, so a modest request in the lower part of that range is the most realistic size; its largest grant in the filings was $12,500,000, which is not a ceiling.
  • Most proposals reach it through direct outreach, and it also issues formal Requests for Proposals from time to time, so watch for one, but the filing does not set out submission steps, so making contact first is sensible.
  • In the filing, 80% of its grant dollars to organisations went to organisations it had also funded in an earlier filing, which suggests existing relationships carry real weight.
  • Its grants are mainly in District of Columbia, New York, California and Massachusetts, but no geographic focus is stated, so organisations elsewhere should not assume they are excluded.

What they fund

Priority Areas

Arnold Ventures focuses on evidence-based policy solutions to America’s most pressing problems, seeking to maximise opportunity and minimise injustice. Its stated areas are criminal justice, health care, infrastructure, public finance, and higher education and career pathways. It supports organisations aligned with those areas, funding research to understand root causes and build evidence about what works, as well as policy development and technical assistance. Its approach targets systems where outcomes fall short and incentives are misaligned, and uses partnerships with policymakers, policy reform and evaluation to pursue lasting, scalable change. Through partnerships with public leaders, it also backs programmes supported by rigorous research and replication studies.
