How Sports Betting Companies Make Money

Sports betting companies can look like they are simply taking bets on games, but their business model is more sophisticated than that. Sportsbooks set betting odds, manage risk, collect wagers, pay winning bets, charge certain fees where applicable, and use pricing models designed to give the operator a mathematical advantage over time.

The key idea is simple: a sportsbook does not need every individual bet to lose for the company to make money. Instead, it builds a margin into its odds and manages thousands or millions of wagers across different markets.

In the United States, the scale of the industry illustrates how large this business has become. The American Gaming Association reported that regulated U.S. sports betting generated about $16.96 billion in revenue from $166.94 billion in handle during 2025.

The Basic Sportsbook Business Model

A sportsbook accepts wagers from customers and sets odds for possible outcomes.

For example, imagine a sportsbook offers:

• Team A: -110
• Team B: -110

A customer betting $110 on Team A would receive $100 in profit if Team A wins, plus the original $110 stake.

The sportsbook does not simply divide the money evenly between the two sides. The odds are designed so that the implied probabilities add up to more than 100%.

That extra percentage is commonly called the vig, vigorish, or overround.

This built-in margin is one of the fundamental ways sportsbooks generate revenue.

What Is the Vig?

The vig is essentially the sportsbook’s mathematical advantage built into the odds.

Consider two sides both priced at -110.

A -110 price has an implied probability of approximately 52.38%.

If you add the implied probabilities of both sides:

52.38% + 52.38% = 104.76%

The amount above 100% represents the theoretical overround.

This does not mean a sportsbook automatically earns 4.76% on every individual game. Actual revenue depends on how customers bet, the final result, promotions, market movement, and other factors.

But across a large volume of wagers, the pricing margin can produce significant revenue.

Sportsbooks Make Money From Betting Volume

The amount customers wager is known as the handle.

Revenue is different from handle.

For example, suppose customers collectively wager $1 million on a group of sporting events. That does not mean the sportsbook made $1 million.

The operator must pay winning wagers and account for other costs.

A simplified example might look like this:

The actual calculation can be more complicated, but this demonstrates the difference between betting volume and sportsbook revenue.

In 2025, U.S. regulated sportsbooks generated roughly $16.96 billion in revenue from $166.94 billion in handle, according to the American Gaming Association.

The House Edge Is Not the Same as Winning Every Bet

A common misconception is that sportsbooks make money because they always know which team will win.

That is not how the business works.

A sportsbook can lose money on an individual game, market, or even a particular day.

Instead, sportsbooks use pricing and risk management to create a long-term statistical advantage.

Suppose a sportsbook accepts a large number of bets at prices that provide a theoretical margin. Some individual bets will win. Some will lose. The operator’s objective is to manage the overall portfolio of wagers so that the expected revenue remains positive over a large sample.

This is similar to other forms of regulated gambling: the operator relies on mathematical pricing rather than needing to predict every outcome correctly.

How Sportsbooks Balance Risk

Sportsbooks monitor how much money is being wagered on different outcomes.

Imagine a football game has attracted:

• $600,000 on Team A
• $200,000 on Team B

The sportsbook has greater financial exposure to Team A winning.

Rather than simply accepting unlimited additional wagers at the same price, the operator can adjust its odds or betting lines.

For example, the sportsbook could make Team A less attractive by changing the price or point spread.

This can influence future betting activity and help manage the operator’s exposure.

Sportsbooks use sophisticated trading systems, statistical models, and risk-management teams to make these adjustments.

Odds Move With the Market

Sports betting odds can change for many reasons.

These include:

• New injuries
• Weather
• Lineup changes
• Betting activity
• New information
• Statistical model updates
• Changes in the opposing team’s situation
• Market prices at competing sportsbooks

The sportsbook therefore isn’t simply publishing one set of odds and leaving them unchanged.

Lines can move throughout the day and sometimes dramatically before a game begins.

Why Sportsbooks Offer Different Prices

Sportsbooks compete with each other for customers.

A bettor might compare the same game across several operators and discover slightly different prices.

For example:

The difference may appear small, but it can matter over many wagers.

Sportsbooks therefore need to balance competitive pricing with their desired margin and risk exposure.

Promotions Are Part of the Business Strategy

Sports betting companies often use promotions to attract and retain customers.

Examples can include:

• Deposit offers
• Bet credits
• Odds boosts
• Free bets
• New-customer promotions
• Loyalty rewards

These promotions can reduce revenue in the short term because the sportsbook is effectively giving customers additional value.

The business hopes that customer acquisition and future betting activity will eventually make the promotional spending worthwhile.

However, promotional terms vary by operator and jurisdiction, and customers need to understand eligibility requirements and wagering conditions.

Customer Acquisition Is Expensive

A sportsbook’s revenue is not the same as its profit.

Operators can spend substantial amounts acquiring customers.

Expenses may include:

• Advertising
• Sponsorships
• Promotional credits
• Technology
• Payment processing
• Employees
• Compliance
• Licensing
• Data
• Customer support
• Taxes

This is why a sportsbook can generate substantial betting revenue while still facing significant operating expenses.

The economics become particularly important in competitive markets where multiple operators are competing for the same customers.

Sportsbooks Also Make Money Through Other Products

Some companies operate more than sports betting.

Large gaming companies may also have:

• Online casinos
• Physical casinos
• Poker
• Racing
• Entertainment businesses
• Hospitality operations

This allows companies to cross-market different products to customers.

However, sportsbook revenue should be distinguished from casino or iGaming revenue when analyzing the financial performance of a specific business.

The American Gaming Association reported that U.S. commercial sports betting revenue reached about $16.96 billion in 2025, while iGaming generated approximately $10.74 billion.

Taxes Take a Share of Revenue

Sportsbooks operating legally in the United States must comply with state and federal requirements.

Tax rates vary by jurisdiction.

This means the amount a sportsbook generates in gross gaming revenue is not the same as the amount it ultimately keeps after taxes and operating expenses.

The American Gaming Association reported that state-regulated sportsbooks generated approximately $3.71 billion in sports betting taxes in 2025.

Taxes are therefore an important part of the business model.

Licensing and Regulation Matter

Legal sportsbooks operate under regulatory requirements that can include:

• Licensing
• Age verification
• Identity verification
• Anti-money-laundering controls
• Responsible-gaming requirements
• Technical standards
• Advertising rules
• Reporting requirements

Requirements differ between jurisdictions.

This regulatory framework creates costs for operators but also distinguishes licensed sportsbooks from unregulated offshore operators.

The American Gaming Association estimated that illegal sports betting still represented a substantial market in the United States, including an estimated $84 billion in annual handle with illegal bookies and offshore sportsbooks in its 2025 analysis.

Why Sportsbooks Can Lose Money

A sportsbook’s mathematical advantage does not guarantee a profit every day.

Large unexpected results can create significant losses.

For example, if an underdog wins and a large amount of money was wagered on that underdog, the sportsbook could have a losing day or week.

Promotions can also reduce profitability.

Technology failures, regulatory penalties, marketing costs, and unusually favorable results for customers can affect financial performance.

The business model depends on operating across a sufficiently large and diversified pool of wagers.

What Is Hold?

Hold is another important concept in sports betting.

In simple terms, it measures how much of the betting handle sportsbooks retain as gross gaming revenue after paying winning wagers.

For example, if customers wager $10 million and the sportsbook generates $500,000 in gross gaming revenue, the hold is:

$500,000 ÷ $10 million = 5%

Hold can vary substantially by month, sport, event, and betting market.

The American Gaming Association’s monthly revenue tracker reports both sports betting handle and revenue, demonstrating how the relationship between the two changes over time. For July 2026, U.S. sports betting generated $1.27 billion in revenue from $11.60 billion in handle.

Why Parlay Bets Can Be Important

Parlay bets combine multiple selections into one wager.

The bettor must generally win all selected legs to win the full parlay.

From a sportsbook perspective, parlays can have higher theoretical margins than some straight bets, depending on the pricing and structure.

This is one reason parlays have become an important part of modern sportsbook offerings.

However, individual parlay results can vary considerably, and a sportsbook can still experience substantial payouts when a large number of popular combinations win.

Sportsbooks Use Data and Technology

Modern sportsbooks rely heavily on technology.

Systems can monitor:

• Betting volume
• Odds
• Customer activity
• Market movement
• Account behavior
• Game information
• Risk exposure

Sportsbooks also use statistical models and real-time data to update betting markets.

For live betting, this becomes especially important because odds can change within seconds as events unfold during a game.

A Simple Example of How the Economics Work

Imagine a fictional sportsbook accepts $100 million in wagers over a period.

After paying winning bettors, suppose it retains $5 million in gross gaming revenue.

That does not mean the sportsbook made $5 million in profit.

It may still need to pay:

• $1 million in taxes
• $2 million in marketing
• $500,000 in technology costs
• $500,000 in staffing and operations

The remaining amount would be its simplified operating contribution before other expenses.

Real sportsbook financial statements are more complicated, but the example shows why handle, revenue, and profit are three different things.

Frequently Asked Questions

How do sports betting companies make money?

Sportsbooks primarily make money by building a mathematical margin into betting odds and managing large volumes of wagers. They can also generate revenue through related gaming products and other business activities.

What is the vig in sports betting?

The vig, or vigorish, is the sportsbook’s built-in margin in the odds. It helps create a mathematical advantage for the operator over a large volume of bets.

Do sportsbooks make money when bettors lose?

Generally, sportsbook revenue comes from the difference between money wagered and payouts to winning bettors. A bettor’s individual loss contributes to the overall pool, but the sportsbook’s financial performance depends on the complete set of wagers.

What is sportsbook hold?

Hold is the percentage of betting handle that becomes gross gaming revenue after accounting for winning payouts. It can vary significantly between periods and sports.

Do sportsbooks always make money?

No. Sportsbooks can lose money on individual games, events, days, or even longer periods. Their business model relies on mathematical pricing and risk management across a large volume of wagers.

Is sportsbook revenue the same as profit?

No. Revenue is generated after accounting for betting payouts, but operators still have expenses such as taxes, marketing, technology, employees, licensing, and compliance.

Conclusion

Understanding how sports betting companies make money starts with one basic concept: sportsbooks build a margin into their odds and operate across a large volume of wagers.

The company does not need to correctly predict every game. Instead, it uses pricing models, risk management, market information, and technology to maintain a theoretical advantage over time.

Handle, revenue, hold, and profit are also different measurements. A sportsbook can accept billions of dollars in wagers without keeping anything close to that amount as profit.

The U.S. market demonstrates the scale of the business. In 2025, regulated commercial sportsbooks generated approximately $16.96 billion in revenue from $166.94 billion in betting handle, according to the American Gaming Association.

Ultimately, the sportsbook business combines probability, pricing, technology, customer acquisition, risk management, and regulation. Its profitability depends not on winning every individual bet, but on managing the entire betting operation over time.
