Predict CEP: Forecasting Tournament

The Cause Exploration Prizes is an essay contest run by Open Philanthropy. This group has one market for each entry, asking: "Will this essay win first or second place?"

To encourage more forecasting, Manifold is sponsoring a forecasting tournament with a $1000 USD prize pool. Show off your prediction or evaluation skills, and win real USD if you're correct!


The intent of this tournament is to reward individuals who are best at predicting which cause exploration essays will win the prize.

  1. USD prizes will be awarded to the top 20 traders in proportion to profit earned in this group

  2. Only 1 account per person can trade in this market

  3. Don't collude with other people to inflate your or their profits

    • Like don't transfer money to your friends account via betting a market artificially high/low and having them correct it

  4. All forms of trading are allowed (including API, limit orders)

  5. Manifold reserves the right to modify rules, exclude participants, and other changes necessary to abide by the spirit of this tournament

Cause Exploration Prize Judgement Criteria

Copied from EA Forum

At Open Philanthropy, we aim to give as effectively as we can. To find the best opportunities, we’ve looked at many different causes, some of which have become our current focus areas.

Even after a decade of research, we think there are many excellent grantmaking ideas we haven’t yet uncovered. So we’ve launched the Cause Exploration Prizes around a set of questions that will help us explore new areas.

We’re most interested in responses to our open prompt: “What new cause area should Open Philanthropy consider funding?”

We also have prompts in the following areas:

We’re looking for responses of up to 5,000 words that clearly convey your findings. It’s fine to use bullet points and informal language. For more detail, see our guidance for authors. To submit, go to this page.

We hope that the Prizes help us to:

  • Identify new cause areas and funding strategies.

  • Develop our thinking on how best to measure impact.

  • Find people who might be a good fit to work with us in the future.

You can read more about the Cause Exploration Prizes on our dedicated website. You’ll also be able to read all of the submissions on the Effective Altruism Forum later this summer – stay tuned!

Prizes, rules, and deadlines

All work must be submitted by 11:00 pm PDT on August 11, 2022 (deadline extended on July 28) August 4, 2022.

You are almost certainly eligible. We think these questions can be approached from many directions; you don’t need to be an expert or have a PhD to apply.

There’s a $25,000 prize for the top submission, and three $15,000 prizes. Anyone who wins one of these prizes will be invited to present their work to Open Phil’s cause prioritization team in San Francisco (with compensation for time and travel). And we will follow up with authors if their work contributes to our grantmaking decisions!

We will also award twenty honorable mentions ($500), and a participation award ($200) for the first 200 submissions made in good faith and not awarded another prize.

All submissions will be shared on the Forum to allow others to learn from them. If participants prefer, their submission can be published anonymously, and we can handle the logistics of posting to the Forum. See more detail here.

For full eligibility requirements and prize details, see our rules and FAQs.
