A bad each way race refers to betting each way on horse races that, thanks to the way place betting odds are figured out, work in the favour of the punter and not the bookmaker. A betting tissue is the first draft of odds calculated for an event. This range of odds do not last long once the money starts to enter the market and odds adjusted accordingly.

For a start, the tissue needs to have the ‘bookmakers edge’ applied to ensure a profit on the book based on the bets taken at the odds on offer. Once they have analysed all the information available, they will set about converting this into the percentage chances of each runner winning the race and create tissue prices. The major bookmakers employ a team of odds compilers to set their prices.

  • Depending on the odds format, a different formula must be used.
  • Changes can occur due to shifts in market dynamics, such as a surge in bets on one side or the other.
  • Plain and simple, but you still need to understand this odds format to use it properly.
  • A parlay is a bet that combines two or more selections into a single wager that has a payout only when all parts win.

Betting odds are intrinsically linked to perceived probability and provided for the punter to ‘buy’, on this basis. Odds are a way to identify the probability of an event occurring. It is the ratio of the probability of an event to happen to the probability of the event not happening. Or send it to that certain someone who still busts out an old school calculator when they make a bet.

Changes can occur due to shifts in market dynamics, such as a surge in bets on one side or the other. Fractional odds are mostly used in the UK and Europe but are standard in horse racing even in the US. These use the fractions such as 5/1 to express the odds and payout on wagers.

If sportsbooks offer an unusual, exotic bet (such as odds on a television show), chances are that they create the numbers themselves. Sportsbooks can get around the high cost of employing a team of experts by outsourcing the majority of their odds and lines to external, third-party consultants. While this still costs money, it’s definitely cheaper than doing them in-house. Synthesizing the insight of mathematicians and statisticians has made the process more quantifiable and way more precise.

Let’s say a soccer player is +200 to score the next goal but has had five shots on goal in the last 10 minutes. A savvy gambler can get some quick value before the bookie has had a chance to reduce the odds. Several factors impact odds, the most prominent being news about each team, potential injuries, public opinion confidence shifts, and money. Bookmakers aim for what’s called an “overround,” a built-in margin that ensures they profit regardless of the outcome. Unlike the often-manual process of setting pregame odds, technology plays a crucial role with live odds.

The Role of Data in Setting Odds

Sportsbooks need to differentiate themselves beyond just the odds themselves, and this comes in the form of massive marketing campaigns. Oddsmaking in these days was grounded more in individual oddsmakers’ individual expertise and their gut feelings, instead of today’s statistics and data. As sports betting started to explode in popularity, however, new ways to make odds would emerge. Handicappers like Jimmy the Greek were still integral to the process, but they wouldn’t be the only people involved in generating odds. As such, it’s integral to understand that the chief function of oddsmakers isn’t to create an accurate (and probable) picture of reality—it’s to mitigate your sportsbook’s risk. Think of contemporary oddsmakers as risk management professionals, as well as expert sports predictors.
