Free to use; no trading costs.
Analytical interface aimed at serious forecasters.
Rigorous, transparent scoring of forecasts over time.
Funding and fee details as of June 2026 and illustrative. Verify current terms with the platform before depositing.

A clear regulator does not make a platform safe to over-trade. Prediction markets can lose you money; trade only what you can afford to lose, never to chase losses, and never on borrowed money.
