An exchange lets users bet against each other instead of against a single bookmaker. You can back an outcome to win, or lay it, which is to bet that it will not happen. The idea is simple and the consequences are not, because laying changes how risk is calculated. This guide explains the concept and its pitfalls, and says plainly that we have not confirmed an exchange at GT99.
Back and lay defined
To back is to bet that something will happen, exactly as on a fixed-odds sportsbook. To lay is to accept someone else's back bet, effectively acting as the bookmaker for that bet. If the backed outcome does not occur, you keep their stake. If it does, you pay out at the agreed odds.
The structure produces a market of waiting offers: backers want longer prices and layers want shorter ones, and bets match when they meet.
The liability calculation
A lay bet carries a liability equal to the stake multiplied by the odds minus one. Suppose you lay 100 at decimal odds of 4.00. If the outcome happens, you pay 300 and the backer's 100 is returned. If it does not, you gain 100.
| Scenario | You lay 100 at 4.00 | Result |
|---|---|---|
| Outcome does not happen | Keep backer stake | Gain 100 |
| Outcome happens | Pay winnings | Lose 300 |
Why that asymmetry matters
The small gain versus large liability pattern is the reason laying long-priced outcomes is hazardous. Each bet wins often and pays little, then one loss erases many wins. Sizing by liability, not by stake, is the rule. If you cannot say what the worst case is for a lay bet, do not place it.
Commission and matching
Exchanges typically charge commission on net winnings. Available liquidity affects how much of your bet is matched at a given price, and unmatched portions may wait or lapse. These are details to read in the rules of the product, if it exists.

The brand facts we have do not confirm an exchange product. Look in the sportsbook section of the official site or app, and treat what you find there as the answer. For fixed-odds cricket, see reading cricket odds and live cricket betting. The cricket hub has the full list.
Questions to ask before using any exchange
Write the worst-case loss before you confirm a lay bet. Check how commission is applied. Confirm what happens if the match is abandoned. If any answer is unclear, do not bet. These three questions take under a minute and prevent the most common surprises.
If you decide the exchange is not for you, nothing is lost: fixed-odds markets cover the same matches with simpler risk. Simpler risk is a perfectly good reason to choose a product.
