Polymarket and Kalshi operate under different market structures, fee schedules, and user bases, which naturally creates pricing spreads. Polymarket and Kalshi can show different implied probabilities for the same outcome because of liquidity, fee structure, participant mix, and how each venue defines the contract. Each platform's liquidity depth, order-book design, and participant demographics influence how quickly prices adjust to news. Arbitrage traders typically exploit these gaps, but temporary divergences persist due to withdrawal delays, platform-specific trading costs, and varying risk appetites among each venue's community.
Key catalysts include roster announcements, injury updates to star players, recent team performance trends, and head-to-head historical matchups. Weather conditions on game day, home-field advantage dynamics, and late-breaking lineup changes can all shift trader positioning. Additionally, any significant trades or managerial decisions in the days leading up to the event may trigger repricing as new information flows into both platforms.
