Argentina, the defending World Cup champions, found themselves genuinely rattled on July 3, 2026. Their Round of 32 opponent at Hard Rock Stadium in Miami Gardens was Cape Verde, a nation of roughly 530,000 people making its first-ever World Cup appearance. Goalkeeper Emiliano Martinez was kept busy, making crucial saves as Cape Verde pressed with an intensity that surprised plenty of observers who assumed this would be a comfortable afternoon for Lionel Messi and company.
Cape Verde’s arrival is genuinely historic
Cape Verde entered the knockout rounds unbeaten, having held both Spain and Uruguay to draws. Cape Verde is the smallest nation by population ever to reach this stage in World Cup history.
Prediction markets noticed. Polymarket recorded $4.7 million in payouts connected to Cape Verde’s group-stage run ahead of the knockout match, reflecting the volume of speculation the underdogs attracted from bettors who either believed in the upset or were hedging against one.
