The bookmaker market means betting with the bookmaker and betting on the odds they offer. When you bet on a traditional bookmaker, you are betting against KV8 rather than against other KV8 customers. Therefore, it is KV8 who sets the prices and carries the risk. 

A betting exchange, on the other hand, offers more competitive odds due to its nature as a peer-to-peer platform, and the market is driven by supply and demand. It matches bets from backers and layers, you could be betting against one person or several in a betting exchange. 

While betting exchanges typically offer higher odds compared to traditional bookmakers for the same selections, it’s important to note that placing a bet on a betting exchange involves paying a commission on your net winnings for each market. This sets it apart from the traditional bookmaker model.
