How a traditional sportsbook works
A sportsbook is the most familiar setup. The bookmaker sets the odds for each event, adds a margin (vig or juice), and takes bets directly from customers.
- You bet against the bookmaker, not other players.
- The book’s goal is to balance action on both sides while keeping its margin.
- Odds are influenced by market demand, sharp money, and trading algorithms.
For example, if you bet $100 on a football team at -110, you’re locked into the odds the sportsbook is offering. If you win, you get paid; if you lose, the bookmaker keeps your stake.
How a betting exchange works
A betting exchange flips the model. Instead of betting against the bookmaker, you bet against other players. The exchange acts as a marketplace, matching backers (who bet for an outcome) and layers (who bet against it).
- Odds are set by supply and demand, not by a bookmaker’s margin.
- The exchange charges a small commission on net winnings instead of building juice into the odds.
- You can both back and lay outcomes — meaning you can act like the bettor or like the bookmaker.
For example, if you believe a tennis player won’t win, you can lay that outcome, taking bets from others who think he will.
Betting exchange vs sportsbook: key differences
- Odds and value
- Sportsbook: Odds include vig, so true value can be hidden.
- Exchange: Often sharper prices since there’s no built-in juice, only commission.
- Who you bet against
- Sportsbook: Always the bookmaker.
- Exchange: Other bettors; the platform just matches and settles bets.
- Flexibility
- Sportsbook: Limited to pre-set markets.
- Exchange: Ability to back or lay, creating strategies like trading or hedging.
- Liquidity
- Sportsbook: Always takes your bet if within limits.
- Exchange: Your bet only goes through if someone matches it; low liquidity can be an issue.
Which is better for bettors?
- Sportsbooks are convenient, easy to use, and guarantee action, but they can limit sharp players and always build in vig.
- Exchanges offer more transparency and often better odds, but require liquidity and can feel more complex to newcomers.
Many professional bettors prefer exchanges for their control and sharper prices, while casual players stick with sportsbooks for simplicity.
