Inaugural Edition · Q1 2026
10 overlooked high-leverage giving opportunities, ranked by expected impact-per-dollar. Each entry includes the problem, neglect analysis, estimated leverage, key uncertainties, and peer-reviewed sources.
Our Top Picks
These represent the strongest combination of evidence quality, neglectedness, cost-effectiveness, and tractability from our inaugural analysis.
Extraordinary cost-effectiveness at sub-cent per capita. Sri Lanka demonstrated a 70% suicide reduction over 20 years. Near-zero philanthropic competition in this space.
Literally cost-saving in most modeled scenarios. A 15-cent test upgrade can prevent 200,000 stillbirths and neonatal deaths annually. Integrates into existing HIV screening.
Affects 815 million children globally. The US proved a 94% reduction is feasible. LEAF has begun catalyzing national regulation, but 70 of 73 LMIC countries still lack it.
Complete Rankings
Each card contains the problem area, why it's neglected, estimated leverage, key uncertainties, and links to primary sources. Entries marked “Top Pick” are our highest-conviction recommendations.
Pesticide self-poisoning accounts for 110,000–168,000 (14–20%) of global suicides annually, predominantly in low- and middle-income farming communities where highly toxic pesticides are readily accessible.
Suicide prevention in LMICs receives minimal philanthropic attention. To GiveWell’s knowledge, there are no other philanthropic funders besides Coefficient Giving supporting policy work to reduce pesticide suicide. The intervention sits at the intersection of agriculture regulation and mental health—two siloed sectors.
Banning highly hazardous pesticides across 14 countries could prevent ~28,000 deaths/year at an annual cost of $0.0071 per capita (less than one cent). Sri Lanka’s bans contributed to a 70% reduction in national suicide rates, saving an estimated 93,000 lives over 20 years. Cost per healthy life year gained is well under $100—classified as “very cost-effective” for LMICs. No discernible reduction in crop yields observed.
Political will varies by country; agricultural industry lobbying; generalizability of Sri Lanka’s success to other contexts; time lag between policy advocacy and implementation.
Mother-to-child transmission of syphilis causes ~700,000 adverse birth outcomes annually, including 200,000 stillbirths and neonatal deaths, with a global burden estimated at 3.6 million DALYs per year.
Congenital syphilis remains a “neglected, stubborn problem” despite WHO elimination targets set in 2007. Screening was deprioritized due to laboratory testing challenges and low health-system priority. COVID-19 further disrupted programs.
A dual HIV/syphilis test costs just 15 cents more than an HIV-only test, followed by a 50-cent penicillin shot. Cost per DALY averted: $24–$111. In Liberia, screening rates jumped from 7% to 88%, saving an estimated 1,300 infant lives. Net savings in most modeled scenarios—the intervention pays for itself.
Health system capacity in the poorest countries; supply chain reliability for penicillin; sustainability of screening coverage gains without ongoing support.
Lead poisoning causes an estimated 1.5 million deaths annually and affects 815 million children worldwide (one in three). 94% of affected children live in LMICs. Lead exposure causes irreversible cognitive damage, reducing IQ and lifetime earnings.
Before LEAF launched, lead poisoning received only ~$15 million/year in philanthropy—less than 1% of funding for comparably deadly diseases like TB or malaria. The issue lacks a visible constituency and crosses multiple sectors (health, environment, industry regulation).
LEAF’s $104M commitment roughly doubled global philanthropic spending on lead. In Malawi, LEEP’s advocacy brought the paint market close to being entirely lead-free. Nigeria passed enforceable lead paint regulation in 2024. The US demonstrated tractability: blood lead levels declined 94% between the 1970s and 2010s through regulation.
Enforcement capacity in LMICs; non-paint lead sources (spices, cookware, batteries) are harder to address; LEAF’s future funding beyond 2027 is uncertain; political disruption to USAID partnership.
Iron deficiency anemia affects hundreds of millions of children in LMICs, causing cognitive impairment, reduced school performance, and lifelong economic consequences. Folic acid deficiency during pregnancy causes neural tube defects.
Low-tech supplementation programs lack the novelty that attracts donor attention. School-based delivery is logistically mundane compared to vaccine development or surgical interventions, despite often producing superior cost-effectiveness.
Iron and folic acid supplements cost pennies per child and have been shown to boost IQ scores by 4.6 points. The innovation is in delivery systems—reaching children consistently through schools at minimal marginal cost. Benefits compound over a lifetime through improved educational attainment and earnings.
Compliance and sustained school attendance; quality control of supplements in supply chains; precise long-term effect sizes in diverse settings.
Micronutrient deficiencies (“hidden hunger”) affect over 2 billion people globally, causing cognitive impairment, weakened immunity, and increased mortality—particularly among children and pregnant women in LMICs.
Iodized salt is an established success (88% global coverage), but expansion to include iron, folic acid, and other micronutrients has stalled due to technical challenges and insufficient investment in scale-up. Progress has plateaued.
The Copenhagen Consensus rated this a top “best-buy” with a benefit-cost ratio of ~30:1. Expanding Ethiopia’s iodization program to include folic acid costs ~$0.02 per capita/year. Double Fortified Salt already reaches 60 million people in India. Salt reaches even the poorest rural populations.
Technical stability of multi-micronutrient formulations; regulatory barriers across 139 LMICs; monitoring fortification quality at scale; industry adoption rates.
Over 2 billion people lack clean cooking facilities. Household air pollution from burning solid fuels causes 3.7 million premature deaths annually—more than malaria and tuberculosis combined. Disproportionately impacts women and girls.
Clean cooking falls between sectors (health, energy, climate, gender)—and is therefore owned by none. It lacks the single-disease focus that drives health funding, and the “tech innovation” narrative that drives energy funding.
Indoor pollution can be 20× worse than WHO guidelines. Climate co-benefits are substantial (household energy contributes ~20% of ambient air pollution globally). Cost per DALY averted is competitive when health and climate benefits are combined.
Behavior change adoption rates; fuel subsidy sustainability; infrastructure requirements for LPG/biogas distribution in remote areas; measuring precise health impact attribution.
An estimated 440 billion shrimp are farmed annually—more individual animals than any other farmed species. They endure eyestalk ablation, extreme confinement, and inhumane slaughter.
Invertebrate welfare has historically received near-zero philanthropic funding. Moral circle expansion to include crustaceans is still nascent. The field lacks the institutional infrastructure of mammalian animal welfare.
ICAW secured six major European retailer commitments within ten months of launching in 2025, affecting billions of shrimp annually. The sheer number of animals affected gives even modest welfare improvements enormous aggregate impact.
Invertebrate sentience remains debated; enforcement of corporate commitments; scalability beyond European markets; early-stage evidence base.
Rapid AI development poses potentially catastrophic risks. Leaders of major AI labs suggest AGI could arrive within 2–5 years. Institutions have not kept pace—the “pacing problem.”
Over 50% of philanthropic AI safety funding comes from a single source (Good Ventures/Coefficient Giving). Many promising policy organizations need diversified funding to maintain credibility. The field has experienced sudden funding drops and opaque decision criteria.
The window for shaping AI governance norms is extremely narrow. Small organizations (<$250K) and fast-moving policy opportunities are systematically missed by large funders. Rethink Priorities estimates productive use of at least $9.3M in 2026.
Timeline to AGI; whether governance interventions can constrain AI development; political feasibility of regulation; difficulty of measuring counterfactual impact.
Over 1 trillion fish are killed annually in farming and wild capture. Farmed fish endure poor water quality, extreme stocking density, and inhumane slaughter. Fish welfare science is in its infancy.
Fish sentience has been historically underrecognized. Aquaculture welfare has received minimal philanthropic attention. The field is early-stage, creating an opportunity to shape industry norms before practices become entrenched.
Fish Welfare Initiative’s farm program was estimated at 7.16× the cost-effectiveness of GiveWell’s top charities. Corporate welfare campaigns for fish are in their earliest stages—analogous to cage-free campaigns for hens a decade ago.
Cross-species welfare comparisons are methodologically contested; fish sentience evidence still developing; farmer adoption rates; limited organizational track record.
SIDS face cumulative climate damages of up to $476 billion by 2050. They contribute minimally to global emissions but are among the most severely impacted. Rising seas and intensifying storms threaten entire nations.
SIDS receive only 0.2% of global climate finance despite being designated a priority. Caught in a debt-climate catch-22: disasters raise debt-to-GDP ratios by an average of 24%, crowding out adaptation investment.
GCA estimates needs at $12 billion/year—6× current flows. Philanthropic funding through ORCA (13 foundations) can catalyze government action. Adaptation investments have high benefit-cost ratios due to small populations and concentrated risks.
Absorptive capacity of SIDS governments; coordination across 39 nations; climate trajectory uncertainty; whether adaptation can keep pace with sea-level rise.
Methodology
Each opportunity was evaluated using the INT framework (Importance × Neglectedness × Tractability), drawing on peer-reviewed cost-effectiveness literature, philanthropic funding flow data, field reports, and expert analyses from GiveWell, Coefficient Giving, Rethink Priorities, Animal Charity Evaluators, and other research institutions.
Rankings reflect our best estimate of expected impact-per-dollar for a marginal philanthropic donor. We weight neglectedness heavily because the first resources invested in a cause tend to be the most cost-effective due to diminishing returns in well-funded areas.
