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. Platform differences stem from distinct user bases, fee structures, and market-making approaches. Polymarket and Kalshi attract traders with varying risk appetites and information sets, causing temporary price gaps. Kalshi's regulatory framework and Polymarket's design philosophy also influence how quickly new information gets priced in. Arbitrage traders exploit these spreads, but friction costs and withdrawal delays can prevent full convergence, leaving room for informed traders to capitalize on mispricings.
