AI Safety Funder Bulletin

Last updated July 28, 2026

This is a digest of funders in the AI safety space. The goal is to give an overview of who is funding in the space that includes the most relevant information for people seeking funds, looking to donate, or looking to work in grantmaking.

These tables are a rough summary of the numbers in the digest and the numbers are often best guesses based on public info; more detail is in the writeup and the footnotes. For funders that do work in multiple cause areas, it only considers grantmaking and staff focused on AIS. Some of the funding may repeat between rows—e.g. Coefficient donating to BlueDot or AISTOF making grants through Manifund—but this shouldn't substantially change the big-picture numbers.

This is intended to be a living document that updates regularly. If you have any corrections, please reach out!

Funder profiles

These are roughly sorted by money moved per year.

▸Coefficient Giving

Website
Background:
- Previously Open Philanthropy, it grew out of a partnership between GiveWell (founded in 2007 by Holden Karnofsky and Elie Hassenfeld) and Good Ventures (foundation started in 2011 by Cari Tuna and Dustin Moskovitz). They're mainly funded by Tuna and Moskovitz, but looking to work with more donors.
Thesis:
- The biggest funder in the space by far; AI safety is one of a dozen cause areas they make grants in. Grants are usually sourced through their own research rather than applications.

- donations: allocating $1b to catastrophic risks in 2026
- grant sizes: $10k to $50m
- number of grants: the Navigating Transformative AI Fund lists 184 in 2025 and 46 in 2026
- staff: ~180 total. ~30/70 staff working on grants seem to be focused on AIS, and I estimated 70 total by amortizing the staff working on operations, communications, and partnerships.
Recent updates:
- They're hiring for DC-based roles in US AI policy; applications are due August 2.

▸Not included

Astralis Foundation: They seem fairly new with not a ton of public info. They're not taking unsolicited funding requests. Based on this job posting from earlier in the year, they have a fund focused on international AI governance aiming to deploy $15m this year.
Navigation Fund: Jed McCaleb's foundation. At one point they announced they were giving $20m/year to AI safety, but this seems to have not materialized and it's now gone from their website.
AI Risk Mitigation Fund: They announced a spinoff from LTFF in 2023, but haven't made any updates or grant announcements on their website. They're one of the funders of Lightcone Commons.
FLI: They were previously more active in grantmaking and still have a PhD fellowship program, but seem to be less focused on grantmaking these days.
Frontier Model Forum AI Safety Fund: It was funded with $10m in 2023. Most of this was distributed in 2024 and 2025 and they now appear to be winding down and spending their remaining funds.

grantmaking.ai: New initiative housed under Manifund, with an initial $1m, see launch post.

▸Notes

Using public grants on https://coefficientgiving.org/funds for the Navigating Transformative AI Fund and the GCR Opportunities Fund. I don't know what the total of nonpublic AIS grants was; total giving in 2025 was reported as around $1B.
