How to Choose a Prediction Market Platform
1. Regulatory Status First
If you're in the United States, regulatory compliance is the most important factor. Only CFTC-regulated platforms provide legal certainty. Using offshore platforms carries legal and counterparty risk regardless of how established they appear. Check CFTC.gov for current registered platforms.
2. Understand the Full Fee Cost
A 2% trading fee sounds small but compounds quickly. On a $100 position that you trade in and out of five times, you pay $10 in fees before considering market outcomes. Calculate your break-even win rate before committing real money.
3. Liquidity Matters for Exit
Low-liquidity markets have wide bid-ask spreads — you may buy at $0.60 when the true market is $0.55, representing an immediate 8% loss. High-liquidity platforms like Kalshi on major events offer much tighter spreads.
4. Match Platform to Your Interests
Different platforms specialise in different market types. Kalshi covers US economics and policy; Polymarket covers global events; Metaculus focuses on scientific and long-term forecasts; Smarkets covers sports. Choose based on where you have genuine knowledge, not just interest.
