There is a significant divergence between prediction market prices and mainstream soccer experts' forecasts. Mainstream consensus views MLS as one of the most parity-driven soccer leagues globally, where playoff upsets are frequent, making the actual probability of back-to-back or 'super team' championships much lower than in European leagues. However, Polymarket retail investors assign disproportionately high weights to teams with internationally renowned stars (e.g., Inter Miami and LAFC) and give the expansion team (San Diego FC) an irrational 5.5% chance to win, defying the historical reality that new teams typically take years to build chemistry. Meanwhile, teams like Columbus Crew, which have shown immense dominance in recent years, have an implied probability of less than 2%.
