On December 4, 2025, we held a panel discussion titled “Growing Needs, Shrinking Aid: Cost-Effective Action in a Year of Funding Cuts.” The discussion, which was moderated by GiveWell co-founder and CEO Elie Hassenfeld, addressed the effects of recent cuts, how GiveWell is responding, and what we’re learning along the way—including our predictions and uncertainties about the future. GiveWell researchers Alex Bowles, Dilhan Perera, Meika Ball, and Rosie Bettle answered questions and shared their latest insights. Watch the video or read the transcript.

Because of limited time, we were unable to answer all of the questions live. Below we’ve answered some of the questions that weren’t addressed during the webinar, along with some additional questions submitted by audience members, focusing on four themes:

• The challenges of an uncertain future
• Taking action in the face of uncertainty
• The role of cost-effectiveness
• Future GiveWell grantmaking

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 listening to the Planet Money episode first, as it provides important context.

Significant changes to foreign aid this year created challenges for implementing organizations—and for funders evaluating which programs to support with limited resources. The Planet Money team followed along as we assessed the effects of the cuts in real time, focusing on our evaluation of a potential grant to ALIMA to maintain nutrition and primary healthcare services in Cameroon.

Following the announcement of the US government's stop-work order and funding freeze in January, we created a rapid response research team and began assessing opportunities we thought were potentially highly cost effective. In March, we launched an investigation of the $1.9 million ALIMA grant, which we funded in June based on the team's findings.

In this episode, GiveWell co-founder and CEO Elie Hassenfeld dives deeper into the grant investigation with Program Officers Rosie Bettle and Alice Redfern, discussing the timeline, modeling approach, and what ultimately led us to make the grant.

It has been a tumultuous year for global health. In early 2025, the US government cut billions of dollars in foreign aid, affecting millions of people around the world and creating substantial uncertainty that continues to ripple through health and development programs around the world.

Drawing on almost two decades of cost-effectiveness research and analysis, GiveWell assessed the effects in real time and identified funding gaps where donors’ contributions could have exceptional impact. Our actions were guided by our core principles:

• Search for highly cost-effective giving opportunities, even in uncertain circumstances.
• Rigorously evaluate those opportunities and share our research publicly, while acknowledging that timely action sometimes requires accepting higher uncertainty.
• Direct funds to where we think they'll do the most good, considering both immediate needs and long-term implications.

In response to funding shortfalls, we funded time-sensitive opportunities to ensure that cost-effective programs could continue. And in response to substantial uncertainty and in expectation of growing needs, we engaged in efforts to research new areas and prepare ourselves for the future. You can read some examples of our response later in this post.

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 transmission is highest, reducing their risk of dying from the disease. Malaria Consortium’s SMC program, which is one of the most cost-effective programs our researchers have identified, has been one of GiveWell’s Top Charities since 2016, and we’ve recommended more than $500 million in grants for the program since that time.

SMC is only delivered during a specific period each year when malaria transmission is highest. The campaigns require careful planning and preparation on a specified timeline to ensure that the drugs are ready to distribute during that window. The funding freeze that started in January jeopardized 2025 SMC campaigns in several countries because of the disruption to funding for these time-sensitive pre-campaign activities.

In this episode, GiveWell CEO and co-founder Elie Hassenfeld speaks with Program Officer Natalie Crispin about how GiveWell responded quickly and flexibly to ensure that SMC campaigns moved forward this year.

Our Beyond the Spreadsheets podcast mini-series lets you ride along with our leadership team on their recent weeklong site visit to Malawi. Recorded daily during the trip, the series shares the behind-the-scenes experience of a GiveWell site visit through real-time reflections and clips of conversations.

At GiveWell, the vast majority of our work is desk-based research—analyzing evidence and modeling program outcomes. Site visits are a small part of what we do, but they add crucial on-the-ground context that raises important questions, challenges our assumptions, and makes our research stronger.

We had two main goals in visiting Malawi. First, we wanted to understand the effects of foreign aid cuts firsthand in a country that may be particularly hard hit. Second, we wanted to see livelihoods programs like GiveDirectly and Spark Microgrants in action, providing insight as we expand our focus on interventions that aim to increase people’s economic well-being.

Throughout the week, the team visited health clinics, schools, and local villages to speak with healthcare workers and community members who shared a glimpse into their lives. Listen to the episodes below to hear a candid, day-by-day account of our learning process and some of the new insights and questions that will inform our future research.

Clean water. Most of us take it for granted. We can turn on the tap and have safe water to drink whenever we want, without having to give it a second thought. That’s not the case for more than a billion people around the world who lack access to uncontaminated drinking water. This is a significant health concern: According to the World Health Organization, more than 500,000 people die each year from diseases caused by contaminated water.

We’ve been thinking hard about how best to build on our past grantmaking to address the huge need for clean water. In January, we launched a public request for information (RFI) to identify organizations who would be interested in implementing chlorination programs in countries with a high burden of waterborne disease.

RFIs are a relatively new strategy for GiveWell aimed at identifying highly cost-effective grantmaking opportunities. The call for water chlorination programs was just the second RFI we issued. The first, completed in 2024, was for research grants, and we’ve since completed another, for programs aimed at increasing vaccination rates. We’ve been excited about the overwhelming interest our RFIs have received. By the March 7 application deadline for water chlorination programs, we had received more than 200 applications. From that group, we recently funded a portfolio of grants totaling around $16 million to support pilots of in-line chlorination programs in six African countries.
