What it means for prediction markets
- Platform choice matters when interpreting prices: The same Republican victory outcome registered at 34.5 percent on Polymarket and 40.5 percent on Kalshi.
- The largest spread was not representative of the average: The six-point presidential gap compares with a 1.1-percentage-point average across the 54 matched outcomes.
- The comparison has limits: It establishes a cross-platform difference, but the supplied material does not show how long that gap persisted or why it emerged.
