1. Overviews

Impact Markets: The Annoying Details (a), Scott Alexander
- Comprehensive description of impact markets, reasoning from first principles. Extremely well-written, and a great introduction to the details of impact markets. Gets technical, but in an easy-to-follow way.
Toward Impact Markets (a), Dawn Drescher
- Comprehensive description of the benefits, risks (& proposed solutions), and current work on impact markets. Fairly technical.
Impact certificates and Impact Markets—Owen Cotton-Barratt
Impact Markets: A Funding Mechanism for Speculative Work
A Fresh FAQ on Impact Markets
Impact Certificates on a Blockchain
Will “impact certificates” value only impact?
Hypercerts: A new primitive for public goods funding
Crypto loves impact markets: Notes from Schelling Point Bogotá
Impact Certificates | Evan Miyazono, Head of Research at Protocol Labs | Green Pill #21

2. Subtopics

Altruistic equity allocation (a), Paul Christiano
- Original proposal of allocating altruistic equity. Somewhat technical.
Certificates of impact (a), Paul Christiano
- Original proposal of impact certificates. Somewhat out-of-date with current work. Somewhat technical.
Impact markets may incentivize predictably net-negative projects (a), Ofer and Owen Cotton-Barratt
- Describes how impact markets can incentivize funding some types of projects that have clear negative expected impact. Argues that impact markets may exhibit the behavior of those types of projects, and therefore that impact markets should never be funded on impact markets.

3. Implementations

Last updated: December 2023

Manifund*, run by Rachel & Austin
- all of Manifund’s internal docs are publicly available
- includes the ACX Forecasting Impact Mini-Grants round, the Open Philanthropy AI Worldviews Contest, and the leftovers of ACX Grants 2024
AI Safety GiveWiki, previously Impact Markets, [?possibly previously something else]
Hypercerts
Gitcoin (not an impact market, but they do retroactive quadratic public goods funding, which is pretty damn close)
NPX Advisors (also in the “close-to-an-impact-market-but-not-quite” category. NPX recently shut down.)

This post originally came from a comment I left on a bounty for charity money to help someone out with an undergrad paper.

*COI: I’ve done some work for, might do some more work for, and own a tiny bit of equity in Manifold, the parent company (?) of Manifund. I’m writing this independent of any work I’m currently doing or planning to do for Manifold or for any other entity. I just think the ideas are cool.
