Pronostics

Pronostics is a term used to refer to forecasts of the likely outcomes of events, most often in sports. It is used in betting contexts and by forecasting communities. In English, the more common term is predictions; pronostics is more frequent in French, Spanish, and other languages, and in some sports media to denote published forecasts. It should not be confused with prognosis in medicine, which refers to the likely course of a disease.

Pronostics are produced by combining data analysis, statistical models, and human judgment. Typical inputs include historical performance, current form, injuries and suspensions, head-to-head records, home advantage, schedule congestion, venue and weather. Betting odds from bookmakers are often used as a baseline or as part of the features. Some pronostics provide probabilistic estimates such as win probability or expected goal difference, while others provide recommended bets or scorelines.

Beyond sports, pronostics can refer to forecasts in other domains such as elections, finance, or weather in some contexts, though the term is less common there.

The accuracy of pronostics varies and is a subject of ongoing evaluation. Critics point to overreliance on past results, data quality, and random variability; disclaimers about uncertainty and risk are common in published pronostics. In regulated markets, providers may be subject to disclosure requirements.
