Guide
Prediction market fees explained
Understand direct fees, spreads, funding costs, withdrawal costs, and why platform comparisons need more than one fee number.
Compare use cases
The lowest-fee platform is not always the best fit if the market is thin, unavailable, or unclear.
Track changes
Fee pages should be updated when platforms change rules, promotions, or funding methods.
Use calculators carefully
ForecastIndex calculators are educational tools and should not be treated as a guarantee of final trading cost.
