We’re optimistic that GiveWell’s funds raised will continue to increase in the long run. Over the next few years, we believe our annual funds raised are more likely to stay relatively constant, due to a decrease in expected funding from our largest donor, Open Philanthropy, offset by an expected increase in funding from our other donors.

In November 2021, we wrote that we were anticipating rapid growth and aiming to influence $1 billion in 2025. Now, our best guess is that we’ll raise between $400 million and $800 million in 2025 (for comparison, we raised around $600 million in 2022). We now think it’s possible but unlikely that we’ll raise close to $1 billion in 2025, and we also think it’s possible but unlikely that our funds raised in 2025 will be substantially lower (e.g. around $300 million) than they were in 2022.

We’re excited about the impact we can have at any of those levels of funding, and we’ll be continuing to direct as much funding as we can raise to the most cost-effective opportunities we can find.

In September, we announced the Change Our Mind Contest for critiques of our cost-effectiveness analyses. Today, we're excited to announce the winners!

We're very grateful that so many people engaged deeply with our work. This contest was GiveWell's most successful effort so far to solicit external criticism from the public, and it wouldn't have been possible without the participation of people who share our goal of allocating funding to cost-effective programs.

Overall, we received 49 entries engaging with our prompts. We were very happy with the quality of entries we received—their authors brought a great deal of thought and expertise to engaging with our cost-effectiveness analyses.

Because we were impressed by the quality of entries, we've decided to award two first-place prizes and eight honorable mentions. (We stated in September that we would give a minimum of one first-place, one runner-up, and one honorable mention prize.) We also awarded $20,000 to the piece of criticism that inspired this contest.

Winners are listed below, followed by our reflections on this contest and responses to the winners.

The post December 2022 open thread appeared first on The GiveWell Blog.

We wrote back in July that we expected to be funding-constrained this year. That remains true as we approach the end of the year, putting us in the unusual position of leaving impact on the table.

We've set a goal of raising $600 million in 2022, but our research team has identified $900 million in highly cost-effective funding gaps. That leaves $300 million in funding gaps unfilled. By donating this year, you can help us not only meet but exceed our goal—and say yes to more excellent opportunities to save and improve lives.

Additionally, our giving guidance for donors has changed this year. For the first time, our top recommendation is to give to our new All Grants Fund, which we allocate to any need that meets our cost-effectiveness bar. We think it's the best bet for donors who want to support the most promising opportunities we've found to help people, regardless of program or location. And it reflects our current views on how we can best meet our goal of maximizing global well-being—by taking advantage of every path to impact, whether that's funding top charities, seeding and scaling newer programs, or funding research.

On June 22, we held a virtual event on research into water quality interventions, featuring presentations from Michael Kremer of the University of Chicago's Development Innovation Lab; Brett Sedgewick from Evidence Action, the parent organization of Dispensers for Safe Water; and Stephan Guyenet, Elie Hassenfeld, and Catherine Hollander of GiveWell. (If you weren't able to attend, we've published a video recording, audio recording, and transcript here.)

We hosted the event to provide some additional background for our recommendation of up to $64.7 million to Dispensers for Safe Water, which installs chlorine dispensers to treat water at rural collection sites in Kenya, Malawi, and Uganda. This grant was the result of a lengthy investigation and a significant update in our views on the cost-effectiveness of water treatment, which we've written about here.

Several attendees wrote in with a range of thoughtful questions—about our analysis of the effects of chlorination interventions, about the particulars of Dispensers for Safe Water's program, or more generally about our work. We covered as many as we could during the event and followed up on others by email. Below, we're sharing a selection of the questions we responded to in writing, along with other questions we've gotten about this work outside of the event, in the hope that they'll be of interest to a broader audience. Questions and answers have been anonymized; some have been edited slightly for brevity, or to fill in important context that was missing.

We’ve decided to rename the Maximum Impact Fund to better describe what opportunities this fund supports. The Maximum Impact Fund will now be called the Top Charities Fund.

We recently announced changes to our top charity criteria that include a new requirement for our top charities: that we have a high degree of confidence in our expectations about the impact of their programs. Alongside this update, we also introduced a new giving option, the All Grants Fund. The All Grants Fund supports the full range of GiveWell’s grantmaking and can be allocated to any grant that meets our cost-effectiveness bar—including opportunities outside of our top charities and riskier grants with high expected value.

The new All Grants Fund is a complement to what we have called our Maximum Impact Fund, which is granted to cost-effective opportunities among our top charities. However, we’ve received feedback that describing the fund which supports grantmaking only to our top charities as having “Maximum Impact” is confusing in light of the opportunity to support a wider range of opportunities (with potentially higher expected value) through the All Grants Fund.

Based on this feedback, we’ve decided to change the name of the Maximum Impact Fund to the Top Charities Fund.

We're extremely excited to be announcing the Change Our Mind Contest to encourage critiques of our cost-effectiveness analyses that could lead to substantial improvements of our overall allocation of funds. For all the details, see this page.

Cost-effectiveness is the single most important input in our decisions about what programs to recommend, and we believe it's possible that we're missing important considerations or making mistakes that lead us to allocate funding suboptimally. We've been excited to see people engaging with our cost-effectiveness analyses, and we'd like to inspire more of that engagement.

With that in mind, we're inviting you to identify potentially important mistakes or weaknesses in our existing cost-effectiveness analyses and tell us about them!

GiveWell UK is now fully registered as a Charitable Incorporated Organisation in the United Kingdom. Our UK supporters now have a tax-deductible option for donating directly to GiveWell!

We've launched GiveWell UK as a UK Charitable Incorporated Organisation (CIO), with the registered charity number 1196392, and the official UK partner of GiveWell. Beginning with the 2022 tax year, eligible UK taxpayers may take tax deductions for donations to GiveWell UK.( These donations are also eligible for Gift Aid.

GiveWell UK donations may be directed toward GiveWell’s Maximum Impact Fund (MIF), All Grants Fund, top charities, or unrestricted support for GiveWell's US operations. Donations will be granted out on a quarterly basis in line with the recommendations of GiveWell’s US-based research team, upon the approval of GiveWell UK’s trustees (more here).

Since 2007, GiveWell has maintained a list of top charities. The organizations and programs on that list have changed over time, but the goal has remained the same: to help donors decide where to give.

In service of that goal, we've spent roughly the last year working on a plan to add to and update our criteria for top charities, so that they accurately reflect our prioritization of funding opportunities and are more helpful to donors. The revised criteria emphasize programs from which we expect high impact, with the additional requirement that we have a high degree of confidence in our expectation.

We hope these changes will also draw a brighter line for donors between our top charities and other excellent funding opportunities we support, a distinction that we haven't always made clear. Recognizing that some donors want to contribute to grants outside our top charities list, we're also introducing a new giving option: the All Grants Fund. Providing this option as a complement to the Maximum Impact Fund is an important step as grants to programs outside our top charities become a bigger part of our work.

In 2021, GiveWell directed the largest amount of money in our history, over $500 million, which we believe will be beneficial or life saving to many people in need. We thank our donors for continuing to trust us to find and recommend some of the most highly cost-effective giving opportunities in the world.

Note that this year, we’ve also updated our metrics report to more clearly communicate about our work. Previously, we reported on our "money moved," a metric that tried to provide a composite picture of both the funds we raised and directed in a given year. However, starting with our 2021 report, we'll be reporting on these metrics separately as "funds raised" and "funds directed," which we believe will be simpler and clearer.

As little as six months ago, we were in the position of having more funding available than we could spend on opportunities that met our very high cost-effectiveness bar. Today, the opposite is true—we don't expect to have enough funding to support all the cost-effective opportunities we find.

In this post we will: provide an update on GiveWell’s projected funding position, explain how we have been successful in identifying cost-effective opportunities, and share our initial thoughts about what this update means for GiveWell’s forward-looking grantmaking strategy.

I am excited to share that GiveWell Managing Director Buddy Shah has been appointed CEO of the Clinton Health Access Initiative (CHAI), a major global health organization working across a range of issues including malaria prevention and maternal and neonatal health. This news is bittersweet for me. I’m sad to be losing the talent, advice, and thought partnership Buddy brought to GiveWell, but I’m thrilled that he is taking up this position—the global health sector will be stronger for it.

CHAI is gaining a great leader in Buddy. But perhaps more importantly for GiveWell and our supporters, this appointment is a signal that effective giving is contributing to more corners of the global health landscape than ever before. Buddy is a strong champion of impact maximization, and I am excited that he will apply this lens in his new role.

As we continue to grow, GiveWell seeks to maximize both the cost-effectiveness of the funding we direct and the likely room for more funding of the programs we support. We think we've identified a category of interventions that rates really well on both: water treatment, such as chlorination.

This is a major update for us. Before 2020, based on the available evidence, we didn’t believe that water quality interventions had a large enough effect on mortality to make them a competitive target for funding. We've since seen new evidence that has led us to significantly increase our estimate of the mortality reduction in young children that's attributable to these interventions: a 14% reduction in mortality from any cause, up from around 3%.

Though we have remaining uncertainties about these numbers, we’ve substantially updated our view of the promisingness of water treatment. Where we previously found that Evidence Action's Dispensers for Safe Water program was about as cost-effective as unconditional cash transfers, we now believe it's about four to eight times as cost-effective, depending on the location. That was a primary factor in our decision to recommend a grant of up to $64.7 million to Dispensers for Safe Water in January 2022.

We're sharing this news in brief form before we've published a grant page, because we're excited about the potential of this grant and what it represents. It's an area of work we haven't supported to a significant degree in the past, but one that we now think could absorb hundreds of millions of dollars in funding for cost-effective programming.

Intermittent preventive treatment in infants (IPTi) for malaria provides preventive antimalarial medicine to children under 12 months old. It is among the most promising programs we've identified in our active pipeline of new interventions. It's also underutilized, and the population it targets is especially vulnerable to malaria. That implies potential to open up large amounts of room for more funding if IPTi begins to be used more widely—our crude estimate is between $50 million and $200 million globally once it's scaled—which is something we're increasingly thinking about as we aim to direct $1 billion in cost-effective funding by 2025. In September 2021, we recommended a small grant to Malaria Consortium and PATH to assess the feasibility and cost-effectiveness of implementing IPTi at national scale in two countries. We're hopeful that this scoping exercise will answer some of our many open questions about IPTi, and that this intervention continues to look promising as we learn more.
