Kalshi and Predict can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Platform differences in liquidity, user base composition, and fee structures can create temporary price gaps even when tracking the same match outcome. Kalshi may attract different trader demographics or have higher trading volume in tennis markets, pushing odds in one direction. Predict might see different information flow or risk appetite among its participants. These divergences typically narrow as arbitrageurs exploit the spread, but during low-volume periods or ahead of major news, meaningful gaps can persist. Monitoring both platforms helps you identify mispricing opportunities and understand which venue has fresher or more confident pricing.
