Professional-grade AI football tools typically consume data from three categories of source. First, match event data: Opta, StatsBomb, or InStat feeds providing expected goals, shot quality, pressing metrics, and tactical positioning data at the event level. Second, contextual data: squad news, injury reports, referee appointments, and weather APIs. Third, market data: real-time odds from 100–400+ bookmakers, tracking line movements that signal sharp money. The integration of market odds as a model feature — rather than just comparing against it after prediction — is a hallmark of the most sophisticated tools, because bookmaker prices aggregate global betting intelligence.
