Volleyball results Monday 14 September 2026: AI predictions review

Monday's volleyball action produced a mixed day for the AI models, with a consensus record of 5 of 8 correct across the European Championships. The headline number masks a day of two halves: five matches went exactly as the models expected, but three results — including one that every single model got wrong — delivered a sharp reminder that volleyball remains a sport where the underdog can bite.

The biggest surprise came in Slovenia's 1-3 defeat to Greece. All 10 models had backed Slovenia to win, with an average confidence of 65%. That result alone accounted for one of the three misses, alongside Romania's 3-1 victory over Turkey and Estonia's 1-3 loss to Belgium.

Action from Monday's European Championships matches.

Where the AI got it right

Ukraine vs Portugal prediction: Ukraine swept Portugal 3-0. Every model backed Ukraine, with an average confidence of 63%. The most common predicted score was 3-1, so the models were slightly off on the margin but spot on with the winner.

Serbia vs Netherlands prediction: Serbia edged Netherlands 3-2 in a five-set thriller. The consensus was Serbia win (100% of models, avg confidence 67%), with 3-1 the most common score. The models correctly identified the winner but underestimated the resistance from the Dutch.

Slovakia vs Czech Republic prediction: Czech Republic won 3-0 away. All 10 models picked the Czechs, with an average confidence of 62%. The most common predicted score was 1-3, so the models got the winner right but expected Slovakia to take a set.

Germany vs Switzerland prediction: Germany won 3-1. Every model backed Germany, with an average confidence of 70% — the highest of any correct call on the day. The most common score was 3-0.

Bulgaria vs Israel prediction: Bulgaria won 3-1. All 10 models picked Bulgaria, with an average confidence of 67%. The most common predicted score was 3-0.

Where it got it wrong

Romania vs Turkey prediction: Romania won 3-1, defying the consensus. 80% of models backed Turkey, with an average confidence of 63%. The most common predicted score was 1-3. This was a clear miss, though the models were not overwhelmingly confident.

Estonia vs Belgium prediction: Belgium won 3-1. The consensus was Estonia win, but only 50% of models agreed — a split vote. The average confidence was just 56%, the lowest of any match. The most common score was 3-1 to Estonia. This was a coin-flip that landed the wrong way.

Slovenia vs Greece prediction: Greece won 3-1, a result that no model saw coming. All 10 models backed Slovenia, with an average confidence of 65%. The most common predicted score was 3-1 to Slovenia. This was the day's biggest upset and the most costly miss for the consensus.
