Predicting a football match before kickoff requires more than knowing past results: a model must use changing information and make a clear prediction before the answer is available. We present WorldCupArena, a dynamic benchmark for language models and deep-research agents.

AlphaBet is a reinforcement learning framework that trains a single large language model to search for evidence, reason about it, and report probabilities for unresolved events across multiple pre-resolution dates. By scoring each dated forecast with a proper scoring rule, AlphaBet uses one resolved event to supervise decisions under varying information states, decomposing forecasting regret into evidence-acquisition and probability-reporting gaps. Experiments on GLM-4.5-Air show that AlphaBet improves Brier scores on Forecast-Dojo and FutureX, attributing gains to multi-date training and better information acquisition and probability reporting.

Abstract: LLM agents are increasingly used for live forecasting, where they retrieve up-to-date information and produce estimates for unresolved future events....

Football score forecasting combines a strong statistical core with a difficult contextual edge. Dynamic Poisson-family models estimate team strength, expected goals, and coherent score probabilities, but do not directly understand roles, tactical matchups, motivation, or how a first goal changes behaviour.
