Spain and Cape Verde Islands played out a goalless stalemate in their World Cup group stage opener, a result that defied the model's pre-match expectations of a comfortable Spanish victory. Our prediction of a 3-0 win for Spain came with an 88% win probability, reflecting the substantial quality gap between the sides and Spain's strong home record—an average of 1.14 goals scored per match against just 0.38 conceded. The draw, assigned only 9% probability beforehand, proved the actual outcome.

The match unfolded in a way broadly consistent with the pre-match setup: Spain dominated possession and created chances befitting their xG of 3.17, while Cape Verde Islands remained compact and offered minimal attacking threat, their xG of just 0.51 reflecting their defensive approach. Yet finishing proved elusive for the designated home side. Cape Verde Islands, despite their away record showing only a single previous fixture, held firm enough to frustrate Spain and escape with a point—a result that gives them genuine hope in the group, however narrow their path forward.

The prediction missed the mark on both scoreline and outcome direction. The model had weighted the gap in squad quality and Spain's attacking potency heavily, underestimating the difficulty of breaking down a well-organized defensive unit in a tournament fixture where pressure can flatten even favored sides. For Cape Verde Islands, a point earned on the road represents a genuine result; for Spain, it marks an unexpected slip in what remains a group they remain favorites to win.
