Why do odds change before the start?
Can anyone give a clear explanation as to why the odds for the same match sometimes shift noticeably before it begins? I was watching a game recently and noticed that the values started out one way but then gradually changed. I realize that news and the actions of market participants can play a role, but I’d like to understand the details better. For instance, how significantly can the team lineup or news of a key player's injury affect the odds? And is it even worth paying attention to these changes when doing your own analysis, or is it better to rely solely on match statistics?

Odds can shift before a sporting event for various reasons. The market is influenced by new information regarding lineups, injuries and suspensions, weather conditions, changes in probability assessments, and the overall volume of bets placed on specific outcomes. Consequently, the odds published well in advance won't necessarily remain the same right before kickoff. Particularly noticeable changes often occur after confirmed lineups are released or major news breaks. However, a shift in odds doesn't automatically mean a specific outcome has become more likely; rather, it reflects how the market's assessment of the event is evolving. Therefore, you shouldn't use odds fluctuations as your sole basis for a decision. It is far more useful to cross-reference them with objective data—such as team form, lineups, statistics, the tournament standings, and news updates. This approach helps you avoid jumping to conclusions simply because a number has unexpectedly changed.
