Start Trading FreeFrequently Asked Questions
Are prediction markets legal?
It depends on your jurisdiction. In the US, only CFTC-regulated platforms like Kalshi are fully legal. Outside the US, decentralized platforms like Polymarket operate in a regulatory gray area but are widely accessible.
How do I deposit money?
Centralized platforms (Kalshi, PredictIt) accept bank transfers and cards. Decentralized platforms (Polymarket) require cryptocurrency - typically USDC on the Polygon network.
Can I lose more than I invest?
No. Prediction markets are not like leveraged trading. The maximum you can lose is your position size. If you buy shares at 30 cents and the market resolves NO, you lose 30 cents per share.
Are prediction markets better than polls?
Studies show prediction markets often outperform polls, especially close to events. The financial incentive encourages traders to find and act on accurate information quickly.
