PredictStamp — The social layer for prediction markets

How it works

Make your prediction

Choose a live question and take a position based on the current market probability.

Explain your reasoning

Share the argument behind your prediction — good forecasting is about how you got there.

Build your reputation

When the event resolves, your score moves with difficulty — harder calls pay more, crowd misses cost more.

Reputation is not popularity.

PredictStamp keeps two scores separate.

Reputation

Predictive Reputation

A measure of how accurate, consistent, timely, and difficult your predictions are.

Popularity

A measure of how much attention, engagement, and discussion your content generates.

You can be popular without being right — PredictStamp makes the difference visible.

Shareable predictions

Stamp your prediction.

Every prediction creates a public, shareable record. Come back later and prove you called it before it happened.
