Overview

Coefficient Giving is a major philanthropic organization that has directed over $4 billion in grants since 2014 across global health, AI safety, pandemic preparedness, farm animal welfare, and other cause areas. In November 2025, the organization rebranded from Open Philanthropy to Coefficient Giving, signaling an expansion from serving primarily one anchor donor (Good Ventures, the foundation of Dustin Moskovitz and Cari Tuna) to operating 13 cause-specific funds open to multiple philanthropists. The name "Coefficient" reflects the organization's goal of multiplying impact through research, grantmaking, and partnerships—with "co" nodding to collaboration and "efficient" reflecting their unusual focus on cost-effectiveness.

Coefficient Giving is widely considered the largest funder of AI safety work globally. Since 2014, approximately $336 million (12% of total grants) has gone to AI safety research and governance, with roughly $46 million deployed in 2023 alone—making it the dominant external funder in a field where most safety research happens inside frontier AI labs. The organization's Navigating Transformative AI Fund supports technical AI safety research, AI governance and policy work, and capacity building, with a $40 million Technical AI Safety RFP launched in 2025 covering 21 research areas.

The organization distinguishes itself through its strategic cause selection methodology—identifying problems that are large, tractable, and neglected relative to their size. This approach, combined with a willingness to fund speculative research and support multiple funding mechanisms (direct grants, regranting programs, pooled funds), has made Coefficient Giving central to the effective altruism funding ecosystem. However, critics have noted concerns about funding concentration, the slow pace of spending relative to the scale of AI risks, and heavy focus on evaluations over alignment research in recent technical AI safety grants.

History and Evolution

Origins (2011-2017)

Coefficient Giving traces its origins to 2011 when GiveWell, the charity evaluator founded by Holden Karnofsky and Elie Hassenfeld, began advising Good Ventures on how to deploy Dustin Moskovitz's philanthropic capital effectively. Good Ventures was established by Moskovitz (Facebook co-founder, net worth ≈$12 billion) and Cari Tuna in 2011. By 2014, this advising relationship formalized into "Open Philanthropy" as a distinct project within GiveWell, focused on identifying high-impact giving opportunities across a broader range of cause areas than GiveWell's traditional global health focus.

In 2017, Open Philanthropy spun off from GiveWell as an independent LLC, enabling it to pursue its own strategic priorities while GiveWell continued focusing on evidence-backed global health interventions. The separation reflected diverging methodologies: GiveWell prioritizes robust evidence of effectiveness, while Open Philanthropy embraced "hits-based giving"—funding speculative, high-variance projects where a few major successes could justify many failures.

Growth and AI Safety Focus (2015-2024)

Coefficient Giving began supporting AI safety work in 2015, when the field was nascent and institutional support was minimal. Early grants helped establish foundational organizations including the Machine Intelligence Research Institute (MIRI), the Center for Human-Compatible AI at UC Berkeley, and the Future of Humanity Institute at Oxford. By 2023, AI safety had become Coefficient Giving's largest longtermist cause area, reflecting growing concern about advanced AI risks among the leadership team.

Year	AI Safety Milestone
2015	First AI safety grants; field had ≈10 full-time researchers
2017	Independent organization; Holden Karnofsky publishes AI concerns
2019	AI safety spending exceeds $20M annually
2022	$150M Regranting Challenge launched (not AI-specific)
2023	≈$46M AI safety spending; largest funder in the field
2024	≈$50M committed; 68% to evaluations/benchmarking
2025	Rebrand to Coefficient Giving; $40M Technical AI Safety RFP

The November 2025 Rebrand

On November 18, 2025, Open Philanthropy announced its rebranding to Coefficient Giving. The change reflected several strategic shifts:

Multi-Donor Expansion: The organization moved from primarily serving Good Ventures to operating pooled funds open to any philanthropist. In 2024, Coefficient directed over $100 million from donors besides Good Ventures; by 2025, non-Good Ventures funding had more than doubled.

Brand Clarity: The old "Open Philanthropy" name created confusion—journalists mistook it for OpenAI, and potential grantees confused it with Open Society Foundations. "Coefficient Giving" was chosen to provide a distinctive identity and resolve that confusion.

Structural Reorganization: The organization restructured from program areas to 13 distinct funds, each with dedicated leadership and transparent goals, allowing donors to support specific causes at scale.

Regranting Ecosystem

Coefficient Giving supports multiple regranting platforms and mechanisms to achieve faster, more distributed funding decisions. This represents a deliberate strategy to complement slower direct grantmaking with nimble, expert-driven allocation.

Funding Flow Through Regranting

Loading diagram...

Long-Term Future Fund (LTFF)

The Long-Term Future Fund is a committee-based grantmaking fund that receives significant support from Coefficient. About half of LTFF funding historically comes from Coefficient Giving donations.

Aspect	Details
Annual Volume	≈$6.7M (2023)
AI Safety Portion	≈$4.3M (≈65% of grants)
Grant Count	≈200 grants per year
Median Grant	≈$15-30K
Decision Model	Committee of fund managers
Transparency	High (public grant reports)

LTFF grants tend toward smaller, faster decisions than direct Coefficient grants, serving researchers and projects that may not yet warrant Coefficient's full evaluation process.

Manifund AI Safety Regranting

Manifund operates a distinct regranting model where individual experts receive budgets to make independent funding decisions. For 2025, Manifund raised $2.25 million and announced their first 10 regrantors.

Named 2025 Regrantors:

Regrantor	Budget	Background	Focus
Evan Hubinger	$450K	Anthropic AGI Safety Researcher, former LTFF manager	Technical AI safety

How to Apply for Funding

Direct Application to Coefficient

The most straightforward path for substantial funding requests:

Step	Details	Timeline
1. Check RFPs	Review active Requests for Proposals	Ongoing
2. Submit EOI	300-word expression of interest describing project	N/A
3. Initial Response	Coefficient responds with interest level	2 weeks
4. Full Proposal	If invited, submit detailed proposal with budget	2-4 weeks to prepare
5. Due Diligence	Coefficient evaluates organization and proposal	4-8 weeks
6. Decision	Grant approval or rejection	Total: 2-4 months

Tips for Applicants (from Coefficient's guidance):

The bar is intentionally low for submitting expressions of interest. Key failure modes to avoid include not demonstrating understanding of prior work (read papers linked in relevant RFP sections) and not demonstrating that your team has prior experience with ML projects. Even uncertain proposals are worth submitting as the RFP is partly an experiment to understand funding demand.

Via Regranting Platforms

Faster and more accessible for smaller grants:

Platform	Best For	How to Apply
Manifund	$5-50K projects, emerging researchers	Create project on manifund.org, contact regrantors directly
LTFF	$10-100K, established track record	Apply via EA Funds
SFF	$100K+, established organizations	Apply during S-process rounds

Finding Regrantors

Many regrantors are reachable through:

Direct outreach: Email or social media (many are publicly active on Twitter/X, LessWrong)
EA communities: EA Forum, Alignment Forum, local EA groups
Professional networks: AI safety conferences (NeurIPS safety track, ICML), SERI MATS alumni
Manifund platform: Create project and regrantors may proactively reach out

Funding Gap Analysis

According to an overview of AI safety funding, total external philanthropic AI safety funding (≈$100M annually) is dwarfed by:

Comparison	Amount	Ratio to Safety Funding
Generative AI Investment (2023)	≈$24B	240:1
Frontier Lab Safety Budgets	≈$500M+ combined	5:1
US Government AI R&D	≈$3B annually	30:1

This funding gap is a persistent concern in the AI safety community, though Coefficient and other funders argue that talent constraints, not funding, are often the binding limitation.

Critical Assessment

Strengths

Scale and Stability: With Good Ventures' multi-billion dollar backing, Coefficient can make commitments that smaller funders cannot. This enables multi-year organizational support, compute grants, and substantial research programs.

Strategic Sophistication: The organization's cause selection methodology and research depth (public writeups, shallow investigations, deep dives) provides unusually transparent reasoning for grant decisions.

Ecosystem Building: By funding LTFF, Manifund, and other regranting mechanisms, Coefficient amplifies its reach while maintaining quality through trusted intermediaries.

Hits-Based Giving: Willingness to fund speculative research acknowledges that transformative progress often comes from unexpected directions, though this increases variance in outcomes.

Limitations and Criticisms

Funding Concentration: With Coefficient representing ~60% of external AI safety funding, the field is heavily dependent on one organization's worldview and priorities. Critics note this could lead to "possible solutions being overlooked or assumptions no longer being questioned."

Evaluation Focus: The heavy focus on evaluations/benchmarking (68% of 2024 technical grants) has drawn criticism. As one researcher noted, "This looks much worse than I thought it would, both in terms of funding underdeployment, and in terms of overfocusing on evals." Critics argue AI Safety Institutes are already well-resourced for evaluation work.

Alignment Neglect: Some researchers express disappointment that "there's so little emphasis in this RFP about alignment, i.e. research on how to build an AI system that is doing what its developer intended it to do."

Slow Spending: Coefficient has acknowledged that "in retrospect, our rate of spending was too slow, and we should have been more aggressively expanding support for technical AI safety work earlier." Key reasons cited include difficulty making qualified senior hires and disappointment with returns to past spending.

Grantmaking Depth vs. Volume Tension: Former technical AI safety lead Ajeya Cotra pursued a more "understanding-oriented" approach to grantmaking --- forming deep inside views about how specific research directions connect to preventing AI takeover, rather than relying on heuristics about researcher quality. This approach produced the narrowly targeted $25M agent benchmarks RFP but involved significant upfront research investment that reduced grant volume. Cotra characterized the broader organizational tension: "developing your views is a tonne of work... and in the meantime, you're not getting money out the door."

Grants Database Limitations: The public grants database "offers an increasingly inaccurate picture" of Coefficient's work, as it generally excludes funding advised from non-Good Ventures donors. Coefficient is considering deprecating it.

Strategic Questions

Question	Context
Funding deployment rate	Is $50M/year appropriate given AI development pace?
Evaluation vs alignment balance	Should more funding go to core alignment research?
Lab relationships	How to maintain independence while funding lab-adjacent work?
Multi-donor model	Will expanding beyond Good Ventures change priorities?
Talent vs funding constraint	Is the field truly talent-constrained, or is this justifying underspending?
Inference compute transition	Should Coefficient prepare to shift from funding human researchers to purchasing AI inference compute as AI becomes more capable?
Crunch time readiness	Does the organization have decision-making processes capable of rapidly deploying billions during a potential intelligence explosion?

Future Strategy: From Salaries to Inference Compute

Ajeya Cotra has argued that Coefficient Giving's spending profile may need to fundamentally shift as AI capabilities advance. Currently, over 80% of grant money goes to human salaries. But in a future where AI systems surpass most human researchers, the optimal allocation might shift heavily toward purchasing API credits and GPU time. Cotra suggests the organization should track what fraction of spending goes toward AI inference for grantees (already occurring via ChatGPT subscriptions and API credits), assess whether this fraction is growing appropriately relative to AI capabilities, and build readiness to deploy large sums rapidly during "crunch time."

Key challenges to this transition include organizational inertia (Coefficient's multi-layer grant approval process is designed for human-scale decisions, not billion-dollar compute purchases), model access uncertainty (frontier models may not be commercially available during the intelligence explosion), and the jaggedness problem (AI may automate some research domains well before others, making it hard to judge the right moment to shift). Cotra suggests Coefficient may want to hedge by investing in AI-exposed assets (like GPU manufacturers) to offset rising compute prices during crunch time.
