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 operates under distinct market rules, fee structures, and user bases, which naturally produces price variation. Polymarket and Kalshi may attract traders with different risk tolerances, information sets, or time horizons. Liquidity depth also varies between venues; thinner order books can amplify price swings in response to large trades. Additionally, platform-specific mechanics—such as position limits, withdrawal policies, or settlement timelines—can influence how aggressively traders commit capital, causing temporary or sustained divergence until arbitrage pressure realigns prices.
