One thing that confuses newcomers to an exchange is seeing a bet sit there without being confirmed. On a bookmaker, every bet is instant. On an exchange, your bet only goes live when someone takes the other side. Understanding the order book — and the difference between matched and unmatched bets — clears this up quickly.

What the order book is

The order book is simply the list of prices people are currently willing to bet at, on both sides of a selection. For each outcome you will see amounts available to back and amounts available to lay at different prices. It is the live picture of supply and demand that sets the odds, an idea introduced in what a betting exchange is.

Matched bets

A matched bet is one where your stake has been paired with an opposing bet from another user. The moment that happens, your bet is live and will be settled when the result is known. If you accept a price that is already on offer, your bet is usually matched instantly because someone is already waiting on the other side.

Unmatched bets

An unmatched bet is one that is waiting for someone to take the opposite side. This typically happens when you ask for a better price than is currently available. Your request sits in the order book until another user is willing to meet it. If no one does, the bet stays unmatched and nothing is risked — it simply does not come into effect.

Why a bet stays unmatched

The most common reason is that your requested price is better than the market is offering right now. For example, if the best available back price is 2.00 but you ask for 2.10, you will wait until someone is willing to lay at 2.10. Other reasons include low liquidity (not many people betting on that market) or fast-moving odds during a live match that leave your price behind. You can usually edit or cancel an unmatched bet at any time before it is matched.

Taking a price vs offering a price

This is the practical heart of it. Taking a price means accepting what is already on the screen — fast and certain, but you take the current number. Offering a price means asking for a better one and waiting — potentially more value, but no guarantee it fills. Experienced bettors choose between the two depending on how confident they are and how quickly the market is moving, a judgment that matters most during in-play betting.

Liquidity: why it matters

Liquidity simply means how much money is available to bet on a market. A highly liquid market — like Match Odds on a big match — has plenty of bets on both sides, so you can usually get matched quickly and close to the price you want. A low-liquidity market has fewer bets waiting, which means you might have to accept a worse price or wait longer to be matched. This is why the same selection can feel easy to bet on in one market and slow in another. Checking the amounts available in the order book before you bet tells you how liquid a market is, and helps you decide whether to take the current price or offer your own and wait.

Frequently asked questions

Why won't my bet match?

Usually because you asked for a better price than anyone is currently offering, or the market has low liquidity. Your bet waits until someone takes the other side.

Can I cancel an unmatched bet?

Yes. While a bet is unmatched, you can normally edit or cancel it at any time. Once matched, it is live and stands.

Does an unmatched bet cost me anything?

No. Only matched bets are active wagers. An unmatched bet risks nothing until it is matched.
