Key differences
Kalshi and PredictIt both allow trading on real-world events, but they operate under different regulatory frameworks and offer very different trading experiences.
Position limits: The $850 problem
PredictIt's biggest limitation is its $850 per-contract position cap. This means you can never risk more than $850 on a single outcome, which severely limits potential profits and makes the platform impractical for serious traders. Kalshi has no position limits, allowing you to size positions according to your edge.
Fees: A significant difference
PredictIt charges 10% on profits plus a 5% withdrawal fee, making it one of the most expensive prediction markets. Kalshi charges roughly 2% on profits with free withdrawals. On a $100 profit, PredictIt takes $15 (10% + 5%), while Kalshi takes about $2.
Data and API access
For quantitative traders and analysts, Kalshi's API is substantially better. It offers REST endpoints, WebSocket streaming, and a full historical data archive. PredictIt provides a basic API and CSV downloads, but lacks real-time streaming and comprehensive historical data.
