On Polymarket and Kalshi, pricing can vary because of differences in user bases, liquidity, and market design. 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. For example, one platform might attract more retail traders, while the other draws sharper players, skewing probabilities. Additionally, each venue has its own fee structure and order flow, which influences how prices adjust to new information.

Injuries to key players, changes in pitching rotations, or weather delays could shift this market as they affect expected performance. Media narratives and pre-game betting trends may also influence trader sentiment. Any last-minute roster updates or coaching strategies released before the game can cause rapid price adjustments on both platforms.
