What is ForecastHub?
One dashboard for all the world's prediction markets. Track real-time probabilities across politics, crypto, sports, science, and more.
Where does the data come from?
ForecastHub pulls live market data from two public prediction market platforms:
- Polymarket — a leading real-money prediction market platform with billions in trading volume. Markets are priced by real traders putting real money behind their beliefs.
- Manifold Markets — a play-money prediction platform with thousands of community-created markets. Broader topic coverage, free to use.
Data is synced automatically every 10 minutes and cached for fast page loads.
How do probabilities work?
Each market has one or more outcomes (typically YES and NO). The probability displayed — say, 72% — means that traders on the underlying platform have collectively priced that outcome at 72 cents per share, implying a 72% chance of resolving YES.
These are crowd-aggregated forecasts. They reflect the wisdom of many traders, but they are not guarantees. Markets resolve when the underlying event occurs and an outcome is confirmed.
