Mexico holds as Korea Republic fades in $27.8M market

Markets opened with Mexico as a narrow favorite at 47.78%, reflecting a tight contest where no outcome commanded strong conviction. The draw was priced at 29.06%, while Korea Republic opened at 23.15%. The favorite probability of 47.02% signaled genuine uncertainty heading into kickoff. Volume reached $27,812,230.64 on Polymarket, showing sustained liquidity throughout the match window.

The away team's win probability collapsed from 23.15% at open to 18.59% at close—a sharp repricing as the match unfolded. Mexico's probability ticked up from 47.78% to 48.74%, while the draw climbed from 29.06% to 32.66%. The market captured 131 discrete price movements across the match, reflecting active trading as participants reacted to on-field developments.

The biggest 60-second swing showed relatively muted movement: Mexico's probability shifted by 0.3% while draw and away legs moved 0.1% each. The limited intraperiod volatility suggests markets adjusted gradually rather than reacting to dramatic momentum shifts. This stands in contrast to high-variance matches where individual moments trigger sharp repricing.

Mexico's home victory validated the market's favorite designation, delivering a correct result. The surprise index of 53 sits in mid-range territory—neither a chalk outcome nor a genuine upset. Markets demonstrated calibration: the favorite won, but the initial probability reflected the genuine competitive balance rather than false confidence.
