Manifold Markets launched in 2022 as a fundamentally different kind of prediction market. Where Polymarket and Kalshi used real money (USDC and USD respectively), Manifold used a play-money currency called “mana.” Users could create markets, bet on them, and accumulate mana — but mana could only be exchanged for charity donations, not cash. This sidestepped all of the regulatory issues that plagued real-money prediction markets.
The model worked surprisingly well. Manifold attracted thousands of users who treated the platform as a serious forecasting tool, even without financial stakes. Researchers used Manifold to crowdsource probability estimates for academic studies. Tech industry insiders used it to predict company outcomes. Forecasting communities used it as training ground for sharpening prediction skills. The play-money model proved that prediction markets could create value even without monetary incentives.
Manifold also became famous for its niche markets. Users created markets on everything: which video game would win an award, whether a specific tweet would go viral, when a particular AI model would be released, whether two people would get married. These ultra-specific markets were impossible on real-money platforms because the volume would be too small to generate meaningful prices. Manifold thrived precisely because it didn’t need volume to function.
The platform became an important counterpoint to the Polymarket-Kalshi mainstream debate. Not all prediction markets had to be about money. Some could be about reputation, accuracy, and the intrinsic satisfaction of being right. Manifold demonstrated that humans will engage with forecasting even when there’s no financial reward — as long as the platform is well-designed and the community is interesting. It was the prediction market equivalent of Wikipedia: free, volunteer-driven, and surprisingly accurate.
