Frequently Asked Questions
Everything you need to know about prediction markets.
What are prediction markets?
Exchange-traded platforms where participants buy and sell contracts based on the outcome of future events. Prices reflect collective probability estimates making them powerful forecasting tools that consistently beat expert opinion.
Are prediction markets legal in the US?
Kalshi and PredictIt are the main CFTC-regulated options for US residents. Polymarket, the largest global platform, is not available to US users. We clearly label each platform's geographic availability in all our reviews.
Which platform is best for beginners?
Manifold Markets is ideal for beginners — it's completely free, uses play-money, and lets you practice forecasting without any financial risk. Once you understand how markets work, Kalshi (US) or Polymarket (international) are the best real-money options.
How do prediction market fees work?
Fees vary significantly. Polymarket charges 0% (free), Manifold is free, Kalshi charges 7% of profits only, and PredictIt charges 10% on winnings plus 5% on withdrawals. Always compare total cost including withdrawal fees before choosing a platform.
Can I make money on prediction markets?
Yes, skilled forecasters can profit by identifying mispriced market events where the market probability differs from their own well-researched estimate. It requires discipline, research, and calibration. We recommend starting on free platforms to develop your edge.
What is the minimum deposit to start trading?
Kalshi requires $10 minimum. PredictIt allows $5 minimum per contract. Polymarket requires approximately $5 in USDC. Manifold and Metaculus are completely free with no deposit required.
