New AI Benchmarks put Football Forecasts to the Test
Football gave AI researchers an unusually useful experiment in 2026.
Before World Cup matches were played, several research teams asked leading language models to forecast results and recorded those predictions before the answers were known. Once the tournament finished, there was nowhere for a bad call to hide.
One of the largest projects was LLM-SoccerArena, a live benchmark developed by researchers from Paderborn University, LMU Munich and the University of Cologne.
Seven language models generated forecasts for all 104 World Cup matches, allowing researchers to compare their performance under different information and prompting conditions.
Football followers encounter AI analysis alongside many other online interests, with Bizbet occupying only a small place in that broader routine.
The research itself tells a more interesting story: access to current information helped the tested models, but only modestly, and confident answers did not automatically mean accurate ones.
World Cup 2026 created a real forecasting test
Traditional AI benchmarks often test models on questions whose answers already exist. Football offered researchers something different in 2026: a fixed schedule of future events with results that nobody knew when the forecasts were recorded.
LLM-SoccerArena used that opportunity across all 104 World Cup matches. Its design varied four elements: the model being tested, its access to information, the prompting strategy and the amount of time remaining before the event.
WorldCupArena approached the same problem from another angle. Published in July 2026, the benchmark evaluated 13 systems across the tournament and asked them to predict more than a simple winner. Tasks included match results, scorelines, players and events, match statistics and tournament outcomes.
That distinction matters. Predicting which team wins is one task. Producing an exact score or anticipating specific events is considerably harder, and the additional categories allow researchers to see differences that a simple win-loss accuracy figure can hide.
The results were far from simple
The 2026 experiments did not produce evidence that one language model had solved football prediction. Instead, different evaluation methods produced different leaders.
WorldCupArena found that systems with similar accuracy on match results could separate more clearly when researchers examined detailed predictions. Its best system achieved only small gains over betting-market and human-fan baselines for result and exact-score accuracy, although the advantage was clearer under its Scoreline metric.
Another study, WC2026-Agents, compared four frontier AI agents across the same 104 matches with pre-match betting-market odds. The models agreed on their top choice in 92% of matches, yet none beat the market on Brier score.
Those findings provide an important warning for anyone reading AI-generated football forecasts. A fluent explanation and a confident percentage do not prove that a system has found an advantage. Forecasting quality must be measured against results and credible baselines over many matches.
Current information helped but not dramatically
One question matters particularly in football: does giving a model access to current information make its forecasts substantially better?
LLM-SoccerArena tested that directly. Models with web access performed better than versions without it, but the improvement in Brier score was only 0.023. That is useful evidence because team news, injuries and other late information might appear essential before kickoff, yet access to more information did not transform forecasting performance.
The result also separates information retrieval from prediction. A system may find recent facts correctly and still make a poor forecast from them. For sports followers, those are two different abilities and should not be treated as interchangeable.
What sports followers can take from the research?
The studies offer a useful lesson for anyone comparing football forecasts online. Check what information a prediction used, when it was made and how previous forecasts were scored. A percentage without a documented track record says very little about forecasting quality.
Online football routines can extend well beyond research, and Bizbet may sit somewhere within that wider mix without serving as evidence for the AI studies discussed here.
The benchmarks instead point readers toward measurable questions: Was the forecast recorded before kickoff? Was the model tested across enough matches? Was accuracy compared with a meaningful baseline?
That approach also makes impressive individual predictions less important. One correct score can happen by chance. A benchmark covering an entire tournament provides much stronger evidence because successful and unsuccessful forecasts remain part of the same record.
Football remains a difficult test for AI
The 2026 World Cup gave AI researchers something unusually valuable: more than one hundred future football matches that could be forecast before anyone knew the answers. LLM-SoccerArena, WorldCupArena and WC2026-Agents approached that opportunity differently, but their results point in a similar direction.
Language models can produce football forecasts and explain the reasoning behind them, yet neither confidence nor access to more information guarantees a correct result. Different scoring methods can also change which system appears strongest.
That makes the new benchmarks more useful as tests of AI under uncertainty than as proof that machines have learned to predict football reliably. The next step is not simply to generate more forecasts. It is to keep recording them before kickoff, compare them with strong baselines and measure performance over enough matches to distinguish genuine forecasting ability from a good run of guesses.
