Harnessing the power of philanthropy to protect our future by providing expert-led, research-driven bespoke grantmaking services to donors to reduce global catastrophic risks and increase the likelihood that future generations inherit a safe, flourishing world.
Longview Philanthropy USA Inc channels philanthropic capital toward reducing global catastrophic risks, with grantmaking centered on frontier AI safety and governance, biosecurity and pandemic preparedness, nuclear weapons policy, and digital sentience research. In 2025, its largest listed grant was $219,000 to Rethink Priorities for public-interest, expert-led research and collaboration to strengthen best practices for AI governance in Europe. Another 2025 grant went to Pacific Forum International for a US-China dialogue to foster mutual understanding and promote public policy development, showing that the foundation also supports policy processes that shape international technology risk management. The organization’s active grant programs include discretionary funds and closed requests for proposals, including the Frontier AI Fund, the Emerging Challenges Fund, and hardware-enabled mechanisms work for AI verification. Its portfolio also includes fellowships and applied research funding on digital sentience, indicating interest in both technical and governance questions around emerging technologies. The foundation is classified as a public charity and operates as a regular funder.
A major theme in Longview Philanthropy USA Inc’s grantmaking is AI governance. That appears in support for Rethink Priorities, where $219,000 was directed to strengthen best practices for AI governance in Europe, and in funding for Ai Objectives Institute, which received $18,843 for the same purpose. The foundation also backs policy dialogue work: Pacific Forum International received $50,000 to support a US-China dialogue aimed at fostering mutual understanding and promoting public policy development. Beyond policy, Longview funds technical safeguards for advanced AI through its hardware-enabled mechanisms work, including closed requests for proposals on verification, tamper resistance, adversarial testing, and related field-building. Its digital sentience programs extend the portfolio into research and fellowships on consciousness, sentience, moral status, and social treatment of AI systems.
The recent grants show a spread from $18,843 to $219,000, with a median of $50,000 across the five listed awards. Grantmaking appears to include both general support and purpose-specific awards, and it is organized through discretionary funds, pooled funds, fellowships, and closed RFPs. Several active programs are not open to unsolicited applications, while some RFP and fellowship tracks do accept them. The foundation is a public charity and a regular funder, not a DAF. The pattern in the listed grants is consistent with expert-led, research-oriented funding rather than individual giving or program-related investments.
