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
Fees are not a flat percentage. On Kalshi and Polymarket US a fee follows price times (1 - price), so 100 contracts at 50 cents cost about $1.75, roughly 3.5% of the stake, and about 6.3% at 10 cents. A fee can apply again when you sell, so trading in and out repeatedly adds up. Calculate your break-even win rate before committing real money, and see Kalshi vs Polymarket fees for worked examples.
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 on major events usually offer tighter spreads.
4. Match Platform to Your Interests
Different platforms specialise in different market types. Kalshi lists economics, policy and sports contracts; 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.
