In the betting market, market demand directly influences the formation of odds. Bookies adjust the odds by analyzing the betting dynamics of the market in real time in order to balance risk and reward. As the number of bettors increases, the odds for a particular option may be adjusted downward to ensure that the bookmaker maintains a certain profit margin in the event of a possible win or loss. This dynamic adjustment allows the odds to reflect not only historical data, but also real-time feedback on players' psychological expectations and betting trends.

In addition, statistical probability also plays a crucial role in odds making. Bookies use mathematical models and statistical analysis to predict the probability of an event's outcome and calculate reasonable odds based on this. When an outcome is widely bet on by the market, the theoretical probability may not match the probability of it actually occurring, at which point the company will adjust the odds to reflect a more realistic risk. For example, an odds table may show the relevant data in the following form:

options (as in computer software settings) betting amount Initial odds Adjusted odds
Team A wins 1,000 dollars. 2.00 1.80
Team B wins 500 dollars. 3.00 3.50
a tie 300 dollars. 2.50 2.40
