How Bookmakers Set Odds & Manage Risk: An Inside Look

While understanding the market is still important, modern oddsmaking is driven by numbers, not just knowledge of the game. Thanks to advanced computing power, oddsmakers can now analyze decades of data and spot trends that would have been impossible to identify in the past. And with the rise in AI and machine learning, their ability to predict outcomes is greatly enhanced.

Why Do Odds Change Before an Event?

To round up our article on betting odds, we’ve covered the most widely used terms to ensure you don’t get confused in your search for winners. When that event ends they pay out everyone who backed the winner and then keep the rest for themselves. Generally, sportsbooks will try to keep their odds somewhat close together so as not to put any other bookmaker at a significant disadvantage (or to prevent taking on unnecessary risk). Differences are usually subtle but can be enough to make a wager more or less valuable, depending on which bookie you’re using.

In general place your main bets pre-event to get the best value and only bet in play if you have a strong instinct a market will move. For example, you don’t want to back Liverpool at home because the odds are poor (1/3 for example). The game kicks off and Liverpool concede an early goal but you think Liverpool will still easily win, in play is giving you odds of evens for Liverpool to win.

If it’s clear that a strong player is on form, their chances of winning are higher, and a bookie will set lower odds on their victory. Calculate the statistical chances of the matches for a weekend and set the odds by taking into account the probabilities and public opinion. To do this, bookmakers offer odds that are adjusted according to the probabilities, which allows it to be lucrative in the long run. If a bookmaker estimates a probability at 1.55 or 1.60, it’s likely that the odds would be set at 1.5.

If the pattern were reversed and £60 was placed at 4/1, however, the bookmaker would be required to pay out £300 and so would lose £180. It is when betting patterns differ from what is expected, therefore, that bookmakers alter pre-event odds in order to balance their books and maintain their theoretical margin for the event. Once a bookmaker has determined what they believe to be the true odds of any outcome occurring in a given event, they will then adjust those odds downwards before offering them to punters. If the bookmaker were to offer those odds, therefore, they would have produced what’s known as a ‘fair book’. That is a betting market where the percentage chances of all of the outcomes add up to exactly 100%.

Whether you’re betting on a match winner, total goals, or even a first goal scorer, understanding how odds are calculated and why they fluctuate can give you a better grasp of the game. It helps you find value in the odds available at online betting sites and better understand implied probability. There are many factors, but some weigh heavier in the balance and these are the ones you should master. Conversely, if an outcome finds few takers, the bookmaker might amplify the odds, rendering it more enticing. This fluidity in odds ensures the bookmaker’s profitability remains intact and the betting market retains equilibrium.

This way, if the favorite does win, the bookmaker’s losses are minimized. If the public overwhelmingly believes that a certain team is more likely to win, then the bookmaker will adjust the odds accordingly to account for the public’s opinion. For example, if the public overwhelmingly believes Team A is a sure win, then the bookmaker may set the odds at Team A -200 and Team B +170. As you will have noticed, the greater the odds, the greater the potential winnings.

They then use this information to set the odds for the match, which should give them a profit regardless of the outcome. Bookmakers set odds to create a balanced book with risk-adjusted profits. When setting the odds, bookmakers consider a variety of factors to determine the likelihood of outcomes and manage their risk.
