Introduction

Understanding how sportsbooks set odds is crucial for any bettor aiming for long-term profitability. In this comprehensive guide, we'll explore the intricate process of odds-setting, highlight the differences between market-making and retail sportsbooks, and provide actionable insights to help you exploit these odds for consistent profits.

Odds are numerical values that represent the likelihood of a specific event occurring. They can be presented in various formats, but we'll focus on the American Odds format:

In American odds:

Bookmakers balance risk management with profit goals when setting odds. The process differs significantly between market-making sportsbooks and retail sportsbooks.

Understanding the Difference Between Sharp and Soft Sportsbooks

Sportsbooks can be categorized as sharp or soft, based on their approach to setting and adjusting betting lines, handling wagers, and managing risk. Here’s a detailed explanation of the differences between these two types of sportsbooks:

Market-making sportsbooks, such as Pinnacle or Bookmaker, set the opening lines and adjust them based on observed betting activity. The process involves:

1. Setting Initial Lines: Sharp sportsbooks, also known as market-making sportsbooks, are the first to set the betting lines for various sports events. They take the lead in establishing the initial odds, which are then often used as a benchmark by other sportsbooks. They start with lower limits and lower vigorish (juice), attracting limited risk to discover accurate prices.

2. Attracting Sharp Action: These sportsbooks actively seek out bets from sharp (professional) bettors. Sharp bettors are known for their ability to identify value and place bets based on sophisticated analysis and modeling.

3. Adjusting Lines Based on Sharp Action: Sharp sportsbooks are quick to adjust their lines based on the betting activity they observe. When sharp bettors place large wagers on a particular outcome, these books adjust the lines and increase the betting limits, refining the odds until they believe they reflect the true probabilities.

4. Low Vigorish: Sharp sportsbooks typically offer lower vigorish (the cut taken by the sportsbook, also known as juice or margin) compared to soft sportsbooks. This attracts serious bettors who are looking for better value on their bets.

5. Higher Limits: These sportsbooks generally offer higher betting limits, allowing sharp bettors to place larger wagers.

6. Market Efficiency: By adjusting their odds based on sharp action, sharp sportsbooks contribute to more efficient markets. Their lines are considered more accurate reflections of the true probabilities of outcomes.

Examples of Sharp Sportsbooks:

For example, if Pinnacle sets an opening line of Bears -3, and sharp bettors believe it should be Bears -5, they will heavily bet on the Bears at -3. Pinnacle then adjusts the line based on this activity, moving it to Bears -5 or beyond, thus reflecting the market consensus.

Retail sportsbooks cater to casual bettors and are more risk-averse. They frequently maintain slower-moving lines, which can be exploitable by sharp bettors. Retail sportsbooks like DraftKings, FanDuel, and BetMGM take a more conservative approach:

1. Following the Market: Soft sportsbooks do not set the initial lines but instead follow the lines established by sharp sportsbooks. They adjust their odds based on the market movements initiated by sharp books.

2. Catering to Recreational Bettors: Soft sportsbooks primarily target recreational or casual bettors. These bettors are less likely to place bets based on sophisticated analysis and are often more influenced by public opinion and sentiment.

3. Higher Vigorish: Soft sportsbooks generally charge a higher vigorish. This larger margin helps them protect against potential losses from less knowledgeable bettors who might not always place profitable bets.

4. Lower Limits: To mitigate the risk of sharp action, soft sportsbooks set lower betting limits. This helps them manage their exposure to large bets that could potentially exploit any inefficiencies in their odds.

5. Slower Line Movements: Soft sportsbooks are slower to adjust their lines in response to betting activity. They rely on the odds movements of sharp sportsbooks and adjust their own odds accordingly, but with a delay.

6. More Promotions and Bonuses: To attract recreational bettors, soft sportsbooks often offer a variety of promotions, bonuses, and incentives. These can include free bets, deposit bonuses, and other marketing tactics to encourage betting activity.

Examples of Soft Sportsbooks:

Target Audience:

Line Setting and Adjustment:

Betting Limits:

To consistently profit in sports betting, focus on exploiting the differences in odds offered by various retail bookmakers. By comparing odds from retail sportsbooks against those set by sharp books—or even between retail books—you can identify scenarios where a particular retail book’s odds do not accurately reflect true probabilities.

For instance, if ABC Sportsbook offers odds at -120 while XYZ Sportsbook offers the same bet at -105, always opt for the better value at XYZ. This approach minimizes your risk and maximizes your potential return.

Understanding the distinction between sharp and soft sportsbooks is crucial for bettors aiming to maximize their profits. Sharp sportsbooks offer better value for informed bettors willing to place large wagers, while soft sportsbooks cater to casual bettors with more promotions and easier-to-exploit odds. By identifying and leveraging the strengths and weaknesses of each type, you can enhance your sports betting strategy and increase your chances of long-term profitability.
