We seek to enable high-quality forecasts on questions relevant to high-stakes decisions, and to ensure those forecasts reach decision-makers. 

Over the past few decades, quantitative approaches to prediction and decision-making have seen tremendous success in sectors as diverse as finance, sports, and retail. And yet, in many other domains, individuals tasked with decisions that will affect the lives of millions or even billions of people — among them politicians, government officials, managers, and technologists — routinely make those decisions using idiosyncratic processes and vague, qualitative assessments of the future.

As a result, when disaster strikes — wars, pandemics, catastrophic failures in critical infrastructure — it’s hard to evaluate whether the institutions tasked with preventing or managing these events could have foreseen them. This limits our ability to learn from such events in a structured way, and gives us little guidance on whom to trust with such decisions and to what degree.

Alternatively, we can use quantitative forecasting, which expresses uncertainty about future events in the form of probabilities, and keeps score of the accuracy of these forecasts once the events have happened. The expression of probabilities reduces communication error resulting from vague qualitative assessments of the future. Pioneering work by psychologist Philip Tetlock demonstrated that selecting excellent forecasters, training them (using e.g. calibration training), and aggregating their forecasts can make these forecasts more accurate, including in high-stakes situations (for example, national elections or geopolitical crises).

At Open Philanthropy, we’ve found forecasting to be a useful tool for our own decision-making; our grantmaking staff often make predictions about core outcomes for grants they approve. And we’ve been making grants to forecasting-related projects since 2015; we’ve supported research by Tetlock and the Forecasting Research Institute, as well as forecasting platforms and software tools such as Metaculus, Mantic, and Sage.


To further our work, we launched forecasting as an independent cause area in 2024. Since then, we’ve begun supporting a growing portfolio of projects aimed at improving decision-relevant forecasts — especially in scenarios where decisions based on false beliefs about the future could lead to catastrophic outcomes, such as evaluating the potential and risks around AI and biotechnology.

Our ultimate goal is to (1) enable more high-quality forecasts on questions relevant to high-stakes decisions, especially those concerning existential and global catastrophic risks, and (2) ensure that these forecasts are taken into account by the relevant decision-makers. Among other areas, we expect to (continue to) find promising opportunities in:

  1. Platform development and practical forecasting tools, including tools that use AI to make better and/or cheaper predictions.
  2. Forecasting research on (among other topics) how to increase the accuracy and relevance of predictions, especially for questions that might be difficult to adjudicate.
  3. Forecasting tournaments focused on particularly crucial questions informing work in our other focus areas.
  4. Projects furthering the adoption of quantitative forecasting in high-stakes contexts, with a particular emphasis on those related to global catastrophic risks.
