Differences in pricing between Polymarket and Kalshi can arise from several factors. These platforms have different user bases, trading volumes, and fee structures, all of which can influence price discovery. Additionally, the specific mechanisms for setting odds—such as order book dynamics on Polymarket versus a continuous probability market on Kalshi—can lead to temporary discrepancies.
