Your guide to partially matched bets in 2021

Matched betting is a type of hedge betting, which is used to cover all eventualities. Used in all types of sports betting, it involves wagering a bet (often a lay bet) at a betting exchange, followed by a back bet at a bookmaker. We assume you do not need to ask, what is Lay betting? If you do not know what this means, or what “lay the draw” translates as, we would suggest you read our guides on these before beginning.

You can only lay your bets provided there is enough money in the exchange. That will only happen if other players back the bet and essentially become your bookie. When they do, your bet is matched. What does a Partially matched bet mean, though?

There needs to be enough free money in the exchange for you to make a Matched bet. This occurs when players “back” the equivalent bet. If they do not back the same event, your bet will not be matched. If you are asking “why is my bet on partially matched”, this is usually the reason. What happens to a Partially matched bet, though? Well, we can tell you this – nothing good.

The idea with laying bets at a betting exchange and placing equivalent back bets at a bookmaker is that you will make money (or at least break even). If you have a Partially matched bet, that is unlikely to happen. Fortunately, there are ways to get around a Betfair Partially matched bet, as you will see.

What is a partially matched bet?

Rather than going through a Partially matched bet definition piece-by-piece, a Partially matched bet on Betfair is best explained with an example. Let us assume you know how to read soccer odds, and you want to make money on football. How does it work?

You are interested in betting on England to beat Germany in an upcoming match. You have looked for decent (but low) odds and found odds of 3.85. You want to back this at your bookmaker with a £10 stake. Then you hurry over to the betting exchange, hoping to place a lay bet on the same odds at an equivalent £10 stake.

You do so, but there is a problem. In the time it has taken you to bet, only £5 is available in the exchange. This means £5 of your £10 stake is matched with the low odds laying system, and the other £5 is unmatched. You have, in effect, a Partially matched lay bet.

How to fix a partially matched bet?

To pocket your winnings, you are going to need to do one of two things. Either wait or lay a bet with other odds if the low odds are gone. Ideally, you will want to place stake money on the best odds margins, but that is no longer possible. So, what can you do? There are two options:

  • You can review your odds with an odds calculator. This will tell you which odds market you need to add to your bet slip and how much to wager to “correct” your bet.
  • You can wait. Sometimes, people will want to back the equivalent event, and more money can be added to the market, thus fixing your Partially matched bet.

These are the only two ways you need if you want to learn how to fix a Partially matched bet. Betfair trading strategies, and other options such as accept all odds movement will not help you here.

Partially matched vs. Unmatched bets

The most significant similarity between an Unmatched bet and bets partially matched at Betfair is that neither of them give you a full bet. Until they are matched, there is no bet in play. The biggest difference is that Unmatched bets remain available as offers until you choose to cancel them.

With Partially matched bets, some of your stake is already in play, so you will need to urgently rectify the issue as you cannot cancel Partially matched bets as easily.

Pros and cons of partially matched bets


  • Partially matched bets are easy to fix if there is more time before the event
  • Ideal for low odds vs high odds betting
  • Rookies cannot end up with partially matched bets at standard bookmakers


  • You need an odds calculator to rectify partially matched bets quickly
  • Common amongst players who don’t understand “liquidity” at exchanges

Frequently Asked Questions about partially matched bets:

No. A Partially matched bet still involves a portion of your stake in play. You need to recalculate your odd and bets to make it work. Unmatched bets can be cancelled and are among the top bets that may be cancelled. Read more in our "why was my bet cancelled?" article.

Yes. Online bookmakers do not let you act as the bookmaker, so they can only be placed at exchanges.

Yes and no. They can be, but only if you really know what you are doing.

That depends. A Partially matched bet requires recalculation to ensure a profit. Unmatched ones can simply be withdrawn, so it is down to each player’s preference, really.

No. Matched betting offers you a guaranteed bet. With matched betting, you have covered your bases. A Partially matched bet is never superior.
