Divergence
Significant divergence exists. Mainstream political ratings (e.g., Cook Political Report, Sabato's Crystal Ball) classify MA-08 as 'Solid/Safe Democratic,' implying a near-zero probability of a Republican victory. However, Polymarket pricing currently implies a ~7.5% chance for the GOP. This discrepancy is not driven by fundamentals but rather by the 'longshot bias' common in prediction markets; traders are unwilling to lock up capital for negligible yields (e.g., 1%), causing the favorite to trade below its true probability and the underdog to be overpriced.
