Greece vs Spain: match prediction on 31 August 2026

Greece are the clear favourites for this World Cup meeting. They carry superior momentum into the fixture, having won four of their last five matches compared to Spain's two victories from the same period. A Greek victory seems the most likely outcome.

The Greek side arrived at this match with confidence, having collected 12 points from their previous five outings. They beat Cyprus 82-75 at home, saw off Poland 89-81 on their own court, and secured away victories against Portugal 76-68 and Romania 91-64. The only blemish came in their most recent game, a 76-82 defeat to Ukraine in the World Cup. That loss does not erase the pattern of dominance that preceded it.

Spain's form tells a different story. Two wins and three defeats in their last five matches left them with just six points. They dispatched Georgia 90-61 and Denmark 74-64, but suffered defeats to Portugal 89-95, Greece 86-90, and Italy 63-67. The Spanish side lost their most recent fixture as well, falling to Portugal by six points at home. Their shooting efficiency has been higher than Greece's — 67 per cent field goal percentage compared to 60.33 — but results have not followed.

The head-to-head record over the past four meetings is evenly balanced, with each side claiming two victories. Spain won 84-77 at the 2024 Olympic Games, but Greece responded with a 90-86 win in EuroBasket last September. Spain also won 87-80 in a friendly in August 2022, while Greece took an 86-70 victory in another friendly that same month. The most recent encounter ended in a Greek win, and the momentum from that result carries forward.

Greece are projected to score 80.5 points and Spain 78.7, a margin of 1.8 points that suggests a tight contest. The expected points figures indicate neither side is expected to dominate heavily. The 0% draw probability aligns with basketball's structure, where a tie is resolved by overtime.

This conclusion stops holding if Spain's shooting efficiency translates into a higher point total than expected, or if Greece's recent defeat to Ukraine signals a vulnerability to World Cup opposition. A draw would also undermine the prediction, though the model assigns that outcome no probability. The margin of victory could easily swing either way given how close the expected points are.
