Dealing with Unmatched Bets and Partially Matched Bets

At some point during your matched betting career, you may find yourself with part of the lay bet matched and the other part unmatched.

Unmatched and partially matched bets are something that most of us will experience at some point. And, unless you read this guide, I can almost guarantee you will panic when it happens to you.

But relax.. it’s not a big problem. There are simple ways to fix it. As well as ways to avoid it happening in the first place!

We'll show you exactly what to do should you encounter an unmatched or partially matched bet!

What are Unmatched/Partially Matched Bets?

To understand unmatched and partially matched bets, you first need to understand how the betting exchanges work. A betting exchange is a platform where you can offer odds to people on events, as well as take odds that others are offering.

So when you place your lay bet, you're saying "I offer these odds and am willing to take a bet up to £X". Usually this is fine, because there are people already lined up waiting for someone to offer these odds and they’re matched with your bet instantly.

But, on small events there is less interest in the market and less of a queue. So there may not be enough money available in the market for someone to take the lay bet you’re offering.

The lay bet could go ‘unmatched’ or worse yet only part of your bet matches (partially matched bets), leaving the rest unmatched.

There isn't anyone wanting to back the the odds you’re offering and the odds increase to the next increment as a result.

Matchbook Example: Unmatched Bet Slip

In the above example, you have placed a £5 lay bet at odds of 3.0. However, none of this has been matched, meaning £5 is unmatched.

Matchbook Example: Partially Matched Bet Slip

In the above example, you have placed a £5 lay bet at odds of 3.0. However, only £0.10 has been matched, meaning £4.90 is unmatched.

This looks the same as the completely unmatched example, however, you'll see that the Matched tab now has a bet in it and you'd see your £0.10 matched lay bet in there.

How To Fix A Partially Matched Bet

Fixing a partially matched bet is a little trickier, but still straight forward with our newly added ‘part lay’ calculator feature!

With partially matched bets, a part of your bet will be matched however a percentage will remain as unmatched bets. What we will therefore need to do is:

  1. Click the cross on Matchbook next to your unmatched bet.
  2. Load up the calculator and select the ‘part lays’ button in the bottom right corner. This will open up an additional section.
  3. In here you will enter how much of your initial stake was matched and the odds it was matched at.
  4. Then, keep everything the same in the top bet calculator section as before, changing only the new lay odds.

The calculator then shows us exactly how much more we need to lay at the new odds to get it back to the way it should be.

Something to note is that because we’re laying on slightly increased odds, the overall profit from the bet will be slightly lower.

How To Fix An Unmatched Bet

Fixing completely unmatched bets - where nothing has been matched yet and your entire stake is still waiting to be matched - is very straight forward.

All it means is that the odds have changed and you weren't able to get the lay bet on at the original price. So what you do is:

  1. Click the cross on Matchbook next to your unmatched bet.
  2. Go back to the calculator and re-enter the lay odds to display what they’re now showing on the exchange.
  3. Place your lay bet as normal with the new stake amount.

How To Avoid This Happening

To avoid this happening in the future you should check how much money is available to be matched on the exchange.


On Matchbook you will see the available amount underneath the lay price. In the below example you can see that the liquidity is £121 for a lay bet against Luxembourg.

Unmatched bets and partially matched bets can create real panic if you don't have much time to resolve it, so make sure you've read through everything in this article and most importantly understood how to avoid it when enjoying matched betting.
