Behind the Research: How Our Team Tackles Hard Questions
In an effort to direct substantially more funding to the most cost-effective opportunities we can find to help people, GiveWell’s research is expanding in two directions at once: going broader, to cover more areas of global health and development, and going deeper, to improve the inputs that inform our decision-making.This episode offers a behind-the-scenes look at how this expansion is p
Pressure-Testing Our Research as GiveWell Grows
GiveWell works to continually improve our research so we can make better grant decisions and direct donations where we believe they can do the most good. GiveWell’s Cross-Cutting research subteam is an important part of that effort—it investigates the impact of the programs we fund, works to resolve our largest uncertainties, and aims to improve our research. As GiveWell’s grantmaking gro
Announcing Our Largest Grant to Date
GiveWell, with co-funding from Coefficient Giving, recently made our largest grant to date: $276 million to the Against Malaria Foundation (AMF) to support the procurement and distribution of 92 million nets in the Democratic Republic of the Congo (DRC) from 2027 through 2029. We estimate that the nets, 46 million of which we think would not otherwise be distributed, will avert roughly 67
Finding the Bottlenecks in Family Planning Access
When GiveWell investigates a new cause area, we’re often focused on two priorities: directing funding where we think it can help people most and generating evidence to inform larger investments later. Family planning is a clear example. Recent foreign aid cuts—including reductions from the US, UK, and Dutch governments—deepened an already substantial need and opened up new cost-effective
Tackling Diarrheal Disease in the Democratic Republic of the Congo (DRC) and South Sudan
Diarrhea is one of the leading causes of death for children under five, killing more than 400,000 children every year. GiveWell has funded several programs to prevent and treat diarrhea, and we recently expanded our work by making a grant to support the implementation and evaluation of WASHmobile in the Democratic Republic of the Congo (DRC) and South Sudan. The program, which was develop
Casting a Wider Net for Cost-Effective Programs
GiveWell tends to be known for its work in areas like malaria prevention, water treatment, and nutrition. But as our research team has grown, so has our ability to search for cost-effective programs across a much wider range of issues.Serious health problems, such as lack of medical oxygen and stockouts of essential medicines at health facilities, affect millions of people in low-income c
Expanding Our Search for Cost-Effective Ways to Reduce Poverty
In September 2025, we created a livelihoods research subteam to specifically focus on programs that increase the economic well-being of people in extreme poverty. While we have evaluated and funded livelihoods programs throughout GiveWell’s history, we now have a dedicated program officer overseeing this portfolio, which has allowed us to build on and deepen that work. Historically, GiveW
What a Decade of Iron Funding Has Taught Us
Anemia, which is commonly caused by iron deficiency, can cause fatigue, cognitive impairment, and complications during pregnancy—and it affects roughly a quarter of the world’s population. Over the last decade, GiveWell has directed nearly $50 million to programs to address this health issue. Because of the large number of people affected and the low cost to provide people with iron, we a
Behind the Analysis: Assessing Past Malaria Nets Grants
GiveWell’s research doesn’t end once we’ve made a grant. We evaluate a subset of completed grants, comparing what we thought would happen to what actually took place, then try to use what we learn to improve our future funding decisions. Over the past year, we’ve formalized and expanded this work, publishing comprehensive “lookbacks” for select grants.A recent lookback on grants GiveWell
Evaluating and Funding a New Kind of Grant (Clubfoot Treatment)
Clubfoot, a congenital condition where children are born with one or both feet twisted inward, affects roughly one in 800 newborns globally. Most of those cases are in low- and middle-income countries, where only about 20% of children with clubfoot receive treatment. While most donations to GiveWell are directed to programs that reduce child mortality, our growing research capacity over t
Scrutinizing One of Our Longest-Funded Programs
Vitamin A supplementation is one of the programs GiveWell has supported the longest, and we’re currently funding it in many African countries. The program has an unusually strong evidence base for reducing child mortality, with multiple randomized controlled trials. Yet, as is the case for most global health programs, the evidence for vitamin A supplementation has complex, unresolved ques
Investing in Information for Greater Future Impact
GiveWell’s primary focus has always been researching, identifying, and directing donations to programs we believe will do the most good. When GiveWell first started, we approached this by looking for organizations that were already delivering highly cost-effective, evidence-backed programs and directing funding to those programs. Over time, we were able to focus further upstream by first
Following the Data on Dispensers for Safe Water
GiveWell aims to find and fund programs that will do the most good per dollar. To do this, we carefully evaluate potential grants before making them—assessing academic evidence, building cost-effectiveness models, and talking to people in the sector who know the program well. But our work doesn’t stop there. When a program we’ve supported nears the end of their funding, we also regularly
Testing New Strategies to Increase Vaccination Coverage
Vaccines are remarkably effective at preventing deadly diseases, and, while global needs for them are great, vaccines already receive substantial global funding. This creates a challenge: How do you identify opportunities where additional funding can meaningfully increase vaccination rates and save lives?GiveWell has long recognized the potential for highly cost-effective vaccine programs
Generating Evidence for the Future of Malaria Prevention
Seasonal malaria chemoprevention (SMC)—a program that provides preventive antimalarial medication to young children during the months when malaria is mostly likely to be transmitted—is one of the most cost-effective programs GiveWell has identified. Malaria Consortium’s SMC program has been one of our Top Charities since 2016, and we’ve recommended more than $500 million in grants to the
Evolving Our Research Approach for Greater Impact
GiveWell is often thought of for its Top Charities, but over the last several years, we’ve been substantially broadening our work. We’ve developed new ways to identify potential grantees, funded research to fill gaps in our understanding, and explored new program areas where we believe cost-effective opportunities exist but other funders aren’t investing. This increased breadth isn’t a go
Testing Our Assumptions through Local Insights
GiveWell has built its reputation on rigorous research—analyzing randomized controlled trials, building cost-effectiveness models, and reviewing monitoring data to identify cost‑effective ways to save and improve lives.In an effort to supplement this desk research and make better decisions, we’ve been working to gather more information directly from the people who live and work in the cou
Taking Lessons from a Year of Aid Cuts into 2026
Global health programs faced major disruptions to their funding in 2025. Back in March, we published our first podcast episode to share a timely snapshot of the immediate impacts caused by the foreign aid freeze and GiveWell’s initial response strategy. It was unclear whether and when funding would resume, and what the medium and long-term implications would be for life-saving programs. O
Growing Needs, Shrinking Aid Webinar Recording
On Thursday, December 4, 2025, GiveWell hosted a live webinar titled “Growing Needs, Shrinking Aid: Cost-Effective Action in a Year of Funding Cuts.” Major cuts to foreign aid this year created deep uncertainty for global health programs. In this live-recorded discussion, co-founder and CEO Elie Hassenfeld moderates a panel of GiveWell researchers to discuss the effects of these cuts and
Behind the Planet Money ALIMA Grant Story
This episode follows up on the November 26, 2025 episode of Planet Money, “Saving lives with fewer dollars,” which covered GiveWell’s evaluation of a grant to the Alliance for International Medical Action (ALIMA) to maintain primary healthcare, hospital services, and malnutrition treatment in two subdistricts of North Cameroon following unexpected aid cuts earlier this year. We recommend
Bridging an Uncertain Time for a Lifesaving Program
Despite significant progress over the past several decades, malaria remains a leading cause of death globally for children under five. This year’s cuts to foreign aid funding disrupted highly effective programs to prevent malaria, such as seasonal malaria chemoprevention (SMC). SMC provides antimalarial medication to children under the age of five during the rainy season when malaria tra

A Frontline View of Foreign Aid Cuts with CHAI’s CEO
Foreign aid funding cuts are reshaping the global health landscape, creating urgent funding gaps and forcing difficult prioritization decisions across health systems worldwide. To understand the real-world effects, it’s essential to hear from the organizations working on the front lines with government partners to navigate the funding crisis. The Clinton Health Access Initiative (CHAI) is
The Fragile Foundations of Global Health Data
GiveWell’s ability to find and fund highly cost-effective health programs relies on a foundation of credible data. A key source of that data, the Demographic and Health Surveys (DHS), recently had its primary funding from USAID discontinued. This creates the potential of a significant challenge for GiveWell’s research—and for evidence-based grantmaking across the global health sector.In t
Advancing GiveWell’s Work on Family Planning
As GiveWell’s research team grows, that increased capacity and expertise allows us to evaluate a wider range of programs to find the most cost-effective opportunities to help people. Over the past year and a half, we’ve been investigating a new research area—family planning services that help people decide whether and when to have children. Family planning programs have particularly compl
Malaria Funding at a Crossroads
Malaria is the cause area where GiveWell has directed the most funding over our 18-year history. We’ve recommended over $1 billion to malaria programs, which we estimate will avert over 200,000 deaths, mostly in young children, through support for programs like Against Malaria Foundation’s insecticide-treated nets and Malaria Consortium’s seasonal malaria chemoprevention.Despite significa
Deepening GiveWell’s Focus on Livelihoods Programs
GiveWell has long grappled with fundamental questions about how to value different positive impacts and make funding decisions across diverse programs. In particular, how much more valuable it is to save a life than to substantially improve it? And how can we prioritize between programs that achieve those outcomes in different measures when there’s no “right” answer to that question?In th
Forecasting the Future of Global Health Funding
In the face of potential major cuts to foreign aid, how can we anticipate the impact on global health and effectively direct resources to the areas of greatest need?In this episode, GiveWell’s CEO and co-founder, Elie Hassenfeld, speaks with Principal Researcher Alex Cohen to discuss the forecasting work GiveWell has undertaken to better understand what the future of global health funding
Exploring HIV/AIDS Funding Cuts and Emerging Needs
The US government has historically been a major funder of HIV/AIDS programs, providing around $5 to $6 billion annually through PEPFAR and other initiatives. With anticipated major reductions in US government foreign aid, including potential cuts of 20% to 50% to HIV/AIDS funding, GiveWell is assessing where new, cost-effective needs might emerge.GiveWell aims to find programs where addit
Supporting Governments Navigating US Funding Cuts
Cuts to US government foreign assistance have created unprecedented challenges for global health programs. Countries that have relied on this funding must now navigate substantial gaps and make difficult decisions about program priorities. In the fourth episode of GiveWell’s podcast series on these cuts, GiveWell CEO and co-founder Elie Hassenfeld speaks with Program Officer Dan Brown abo
Making Cost-Effective Grants Amid Uncertainty
The US government has historically spent approximately $12 billion to $15 billion annually in foreign assistance dedicated to global health. The funding cuts announced in the first few months of 2025 disrupted the global health landscape and created the possibility of enormous funding gaps that are still coming into focus. In response, GiveWell has approved around $18 million in grants to
Addressing Urgent Needs in Seasonal Malaria Chemoprevention
Our first episode shared a broad overview of the impacts of US government aid cuts and GiveWell’s initial response. This time, GiveWell Program Officer Natalie Crispin joins CEO and co-founder Elie Hassenfeld to zoom in on a specific case, focusing on grants we’ve made to support urgent funding gaps for seasonal malaria chemoprevention (SMC). SMC is one of the most cost-effective programs
GiveWell’s Response to USAID Funding Cuts
In this discussion between GiveWell CEO and co-founder Elie Hassenfeld and Senior Program Officer Julie Faller, we provide snapshots of how US funding changes are affecting global health programs:Immediate program trade-offs: As funds are paused, country governments are having to choose between essential health services, including one country that said it would prioritize HIV treatment pr
