Each platform attracts a different user base with varying risk appetites and information advantages, leading to differing opinions reflected in the prices. Trading volume also plays a role; higher volume on one platform can lead to more efficient price discovery. Additionally, the specific market structures and fee schedules on Polymarket and Kalshi can influence trading behavior and, consequently, the odds. These dynamics create opportunities for arbitrage, but also explain why discrepancies can exist.
