Prices on Polymarket and Kalshi can diverge due to several factors. 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 has its own user base, trading dynamics, and fee structure, all of which can influence price discovery. Differences in market design – such as the types of outcomes offered or the liquidity available – also contribute to price discrepancies. Furthermore, information flow and interpretation can vary between the two platforms, leading to differing expectations about the Ige vs. Martinez fight. These differences are a natural part of a decentralized prediction market system.
