Market efficiency in sports betting refers to the idea that all available information—such as team performance, player statistics, injuries, and historical data—is quickly and accurately reflected in the betting odds set by bookmakers. In an efficient market, it becomes challenging for bettors to consistently find value bets or profit opportunities because most relevant information has already been priced into the odds. This concept impacts betting strategies by encouraging bettors to focus on identifying inefficiencies rather than merely reacting to odds changes.
