Predimarkt is a play-money prediction market platform built for learning, experimentation, and collective forecasting.
The public working app is available at predimarkt.eu.
It lets people create markets about future events, trade on possible outcomes, and watch probabilities shift as new information appears. The focus is not on gambling or speculation, but on making uncertainty visible and giving people a practical way to explore how beliefs change over time.
The project is intentionally simple: no real money, no investment pitch, and no unnecessary complexity. It is designed as a small, independent space for curious minds who want to think more clearly about forecasts, incentives, and crowd judgment.
