The adjustment mechanism of odds is an important tool for bookmakers to respond to changes in the market, which reflects the behavior of bettors and the supply and demand relationship in the market. In the pre-match period, bookmakers usually set initial odds based on historical data and expert analysis. Subsequently, with the gradual activation of betting in the market and the continuous updating of information, the odds will be dynamically adjusted according to the following factors:

  • Changes in betting volume: When there is a significant increase in the amount of bets placed on a particular side, the bookmaker may reduce the odds for that side to balance the risk.
  • Impact of information:: Changes in factors such as injuries, illnesses, weather, etc., for example, can lead to adjustments in the odds, as they may affect the probability of the outcome of a match.
  • market sentiment:: The public's tendency to bet on a particular team prompts bookmakers to adjust their odds to maintain a competitive market.

This kind of odds adjustment is not only to protect the company's interests, but also to capture the market reaction keenly. When the market reacts faster and information spreads rapidly, bookies need to adjust their odds more frequently. Research shows that changes in odds usually trigger further betting behavior, creating a feedback loop. Specifically, there are several ways in which odds changes can influence market reaction:

  • Bettors' psychological expectations: Bettors will reassess the chances of a particular side winning when they see the odds change, thus influencing their betting decisions.
  • aggregation effect: High odds may attract bettors to concentrate their bets on a particular side, further affecting the supply and demand in the market.
  • risk avoidance: In order to avoid potential losses, bettors often choose to react on the basis of the latest odds, thus driving price fluctuations across the market.
