About this video: How Exchange Bets Get Matched
How Exchange Bets Get Matched explains what happens after you place a bet on a betting exchange. You bet against other customers, so every back bet needs a lay at the same price. Until then, your bet waits in the market as unmatched.
First, the video shows an unmatched bet. The best price is 2.90, but you ask for £50 at 3.00, so your bet joins the queue. Then another customer lays £30, which leaves you £30 matched and £20 unmatched. If the team wins, you are paid on the £30 only.
Next, it covers kick-off and liquidity. Exchanges usually cancel unmatched bets when a match goes in-play, unless you keep them. Also, a £500 bet with only £200 waiting at 2.00 takes 1.99 and 1.98 as well, for an average of 1.992.
Finally, it explains the in-play delay. In-play bets wait a few seconds, so your price may move or the market may suspend. So trade when the game is quiet, and look for money several times your stake.
However, rules and offers change. For that reason, we check every video against the Gambling Commission and other official sources. In fact, we last checked this one on 13 October 2026.

On a betting exchange, your bet only counts once it’s matched. Here’s how matching works, and how liquidity and the in-play delay affect you.
You don’t bet against a bookmaker. Every back bet needs a lay from another customer at the same price. If nobody wants your price yet, your bet waits in the market as unmatched.
For example, the best price to back a team is 2.90, but you ask to back £50 at 3.00. Your bet joins the queue. Then another customer lays £30 at 3.00.
So you’re £30 matched and £20 unmatched. If the team wins, you’re paid on the matched £30 only: £60 profit before commission. You can cancel the other £20 until it’s matched.
When the match goes in-play, exchanges usually cancel unmatched bets unless you chose to keep them. So check the setting, because a forgotten bet kept in-play can be matched after a goal.
Liquidity is the money waiting at each price. Say you back £500 at 2.00, but only £200 waits there. You also take 1.99 and 1.98, for an average of 1.992.
In-play, bets wait a few seconds before they reach the market. Then your price may still be there. However, it may have moved, leaving you unmatched, or the market may suspend and cancel your bet.
So look for money several times your stake, and trade when the game is quiet. Remember your TV pictures lag behind the action. Finally, check your open bets before you leave a market.
