How Do Betting Sites Make Money
When it comes to making money, sports betting websites rely on two things.
- Vigorish
- Strategies
Both of these factors decide the fate of the sports betting business. Let’s take a closer look at them.
What is Vigorish?
The vigorish majorly depends on the odds. Betting companies adjust the odds of betting to ensure they get their cut, no matter what the outcome is. The calculation of vigorish comprises mathematics. The mathematics that heavily involves probability. Every outcome comes with a certain probability and the sum of the probabilities of various outcomes should be 1.
But that’s never the case. The sum of odds that are provided by the bookmakers is usually more than 1. Why? Because the excess probability is the vigorish that converts into the bookmaker’s margin (also known as over-round). The vigorish can range from 2% and can go over 20%. The real-time odds are adjusted to ensure the bookmaker gets the cut for their service.
Vigorish can be calculated in a simple two outcome event with an easy formula.
V=100& (1-(p*q)/(p+q))
In the above formula, V is vigorish, and p and q are the decimal payouts.
Vigorish heavily depends on the odds. And there are several factors that influence it. The behavior of bettors for the provided odds, the behavior of professional bettors (also known as sharps), the win percentage, etc are the factors that need to be considered for calculating the vigorish.

Alternative Ways in Which Sportsbooks Make Money

Strategic Sports Betting Odds
Sportsbooks generate revenue through strategically calculated odds that inherently favor them, ensuring profitability irrespective of the outcome. They also offer a variety of bet types, including moneylines, point spreads, and totals, each with specific odds designed to contribute to their overall earnings.

Betting Commission
Online betting platforms earn money by taking a commission on each bet. This commission, typically 5-10% of the bet amount in sports betting, changes depending on the odds and the betting option. This system provides the platforms with a regular income, no matter if the bet wins or loses.

Loyalty Programs & Subscriptions
Gambling sites frequently utilize subscription services or loyalty programs to foster repeat betting. These initiatives often provide benefits like free spins, cashback rewards, or special offers, motivating users to continue placing bets. These subscription-based models establish a consistent and reliable revenue stream for betting companies.
Strategies Used to Maximize Profits

Balancing the Bets
One of the common strategies used by sportsbooks to maximize their profits is that of balancing. Online sports betting sites always aim to balance the game, that is, they ensure equal numbers of bets get placed on both sides. This is done to ensure they get their margin irrespective of which side wins the bet. But what about games in which there is no possibility of equal bet on both sides? In these cases, the odds get adjusted and payouts get smaller to ensure the sportsbook gets its cut.

Odd Adjustment
The odds are typically released by the main operator, but those odds are never used. To ensure the sportsbook gets the cut, the odds are changed several times. This is one of the reasons why bettors see varying odds on the website. Every sportsbook employees risk analysts or odds compilers who refine the odds based on several factors. These factors are referee, form of players, player injuries, form of the teams, the result of the past played matches, old records, the result of matches between the teams, home crowd advantage, and several more. At the initial level, betting limits are placed but as the odds get finalized on the basis of opinions of the public as well as professional bettors, the limits are removed. The opinion of the sharp bettors holds most value when it comes to shaping the odds, since they know ins and outs of the game.

Analysis of User Behaviour
How do betting sites make money? By analyzing user behavior. Several noob bettors often place bets on their favorites while sharp bettors who know the game and how betting works analyze all the odds. People often bet on their favorite teams as well as players and when these teams or players fail to perform, most money is made by the sportsbooks. This is one of the reasons why several sports betting sites have a favorite section which contains the most popular sports that are loved by people. In addition to this, several sportsbooks also make use of AI which analyses and understands user behavior and past choices and shows them the odds and bets preferred by them, irrespective of the chances of winning. This enables sportsbooks to push the bets that are in their favor. The biases and inclination of users towards their preferred bets enables sportsbooks to reap huge profits

Bet Capping
To mitigate substantial losses, especially in highly unpredictable events, bookmakers might significantly restrict the maximum allowable bet size.

Line Adjustment
Bookmakers initially set odds, known as the sports line. They then track how bets are distributed. If too many bets come in on one outcome, creating a risk, the bookmaker adjusts the line. This involves lowering the odds after sports betting odds calculation on the popular outcome to encourage bets on less popular options. They also monitor team conditions, weather, and rumors to inform these adjustments.

Hedging Strategies
Risk management in sportsbooks include some bookmakers to bet on opposing outcomes, especially when a majority of bettors favor a single team or athlete. Bookmakers also diversify their offerings by providing various betting options across different sports to limit their reliance on any one particular outcome.

High Stakes for Low Volatility
One of the most common bookmaker profit strategies is attracting high stake bettors. Online sportsbooks, while serving regular bettors, also draw high-stakes gamblers. Big bets can lead to large operator losses, so bookmakers use tactics like analyzing betting patterns, setting limits for big bettors, and partnering with other platforms to reduce risk.
How Profitable is the Sports Betting Business?
There was a time when betting was considered a fun activity. People used to place bets for a few bucks and it was all for the sake of entertainment only. There was also a time when people were intimidated by the idea of visiting bookies and sportsbooks to place bets.

According to another report, the size of the online betting industry is estimated to be $77.18 billion by the end of 2025, which means the industry will grow double in size.
Now let’s take a moment to take a look at some of the extreme profit-generating businesses.
