South Korea vs. Czechia — Kalshi World Cup Market (10 p.m. ET, FS1, Estadio Akron, Guadalajara)
This match matters more than most opening-day fixtures. The winner controls their own destiny in 2026 World Cup Group A. Mexico is a heavy favorite to advance while the loser faces a must-win against South Africa in Matchday 2. Son Heung-min leads South Korea in what is almost certainly his final World Cup, coming off unbeaten qualifying with 10 goals. Czechia reached the tournament through two consecutive penalty shootouts in five days and arrive with a new manager who has only coached two competitive matches. Both teams must deal with Guadalajara's heat and elevation. This is a factor Korea's manager acknowledged as a significant challenge for all three of their group matches.
