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. Price discrepancies between Polymarket and Kalshi on this market can arise due to several factors. Differences in trader demographics, liquidity, and market-making activity all contribute to varying price formations. Polymarket may attract a different class of traders than Kalshi, leading to distinct interpretations of the same information. Furthermore, the volume of trading on each platform – currently $21,540 overall – impacts price discovery. These factors create independent price signals, even for the same underlying event, and explain why odds aren't always identical across venues.
