What are Manifold bounties?

From time to time, a member of our community goes above and beyond in helping Manifold make prediction markets accessible & ubiquitous. We’d like to recognize such contributions publicly, and include a token of our appreciation in the form of M$!

Examples of community work that may be eligible for a bounty:

  • Blog posts, markets, or comments which lead us to significantly change our views
  • A track record of creating markets that help people make better decisions
  • Promoting Manifold & forecasting to a wider audience
  • Identifying serious exploits with our financial infrastructure

Have something cool to share with us? Drop by our Discord or send us an email at (especially for exploits)

Our community is the beating heart of Manifold; your individual contributions are what make this platform valuable at all. Thanks to everyone listed here (as well as countless unnamed others) for your help & support!

Final note

If a particular contribution isn't listed here, that doesn't mean we didn't really appreciate it. There’s so much great work by our community; we aren't always able to catch them all!

If you feel that someone's exceptional contribution has fallen through the cracks (including your own!), please consider creating a market for “Will <X> be recognized for a Manifold bounty?” and posting it on our Discord. Thanks!
