Betfair Exchange

Betfair Exchange – it’s quite surprising that many punters still don’t know exactly how to use it or even have an account.

For any serious punter, the Betfair Exchange is a no-brainer. It gives you the opportunity to access huge worldwide betting pools on most racing and popular sports markets.

We’re going to run you through what Betfair is and how it works, starting with the basics.

Betfair: What is it?

Betfair is the world’s largest betting exchange, and the only exchange that operates in Australia.

A betting exchange is not a traditional bookmaker, which takes bets from punters and pays out to winners. A betting exchange instead merely hosts bets between punters.

Betfair: How does it work?

When placing a bet on the Betfair Exchange, you have the option to either Back or Lay your selection.

Backing is a bet in the more familiar sense: you’re betting on your selection to win, and you collect your winnings if it does.

Laying is the opposite: you’re betting against the selection winning, and you collect if it doesn’t win. It’s really what a traditional bookmaker does: he wins your stake when your selection fails to salute.

Think of it like any bet you might have placed with a mate about, for example, a game of footy. All Betfair does is host that same thing on a grand scale, connecting punters across the world who are opposing each other on a wager.

Betfair Exchange: Matching

Of course, for a bet to take place, there must be two punters on either side of the wager who agree on the odds and the stake. That’s called matching: a bet is locked in when the back and lay side match.

Check out a sample race market:

The cells in blue represent the Back side of the market. Those in pink are the Lay side.

The large numbers in each cell are the available odds for each horse.

How to use Betfair: Odds

The odds system is straightforward. The displayed odds – for Back bets at least – are the same format as you see with any traditional bookmaker.

Odds of 5.5 on a horse? Back it and your stake (say, $100) goes in, and you’ll collect $550 if it wins (before commission). That’s a profit of $450 (more on commission later).

Lay betting is the other side of the wager, the role traditionally played by a bookmaker. If you wish to Lay something, you put up the backer’s winnings (your liability), and you collect their stake if they don’t win.

Using the same example: on the lay side, your liability is $450, which goes into the bet. If the horse wins, the backer wins the $450 and you lose it. If it doesn’t win, you get their stake: $100 before commission.

Betfair: Market depth

A bet needs a backer and a layer for a bet to be matched. On both sides of the equation you can nominate whatever odds you like: if you’re a long way off the rest of the market however, it won’t get matched and no bet will be placed.

You’ll notice that as well as the odds in each cell, there’s another, smaller number below.  This is the current volume available in the market at those odds.

Cell marked in blue is the best (ie highest) odds available to back that selection. The two cells left of it are the next best available, and the volume available there.

The lay side is, again, the opposite. The pink cell is the best (ie lowest) available odds to lay that selection, along with the amount available to be matched.

The first punter in a market enters his stake at his desired odds, and the first person to lay those odds on the other side matches the bet, and it’s finalised.

The best odds placed (and the volume) are always the first at the front of queue, and will be the first matched. The market then works it’s way through the unmatched odds, continually matching wherever there’s available funds, at the same odds, on both sides.

Betfair: Your bet status

So when you place a bet, your betslip will show one of the following:

Matched: your bet has been matched and finalised – you’re on!

Unmatched: your bet has not been matched at your odds: it’ll sit in the queue until it is. If it isn’t matched when the market closes, the bet is simply void and your funds returned.

Partially Matched: just a mix of the two above, which occurs when the volume available is such that a portion of your bet is matched, and a portion isn’t.

On any unmatched funds, you can choose to adjust your odds in order to bring them closer to the current best odds and thus make them more likely to be matched.

The volume in any market obviously depends on its popularity and how many people are betting on it. So the volume in high profile events like English Premier League soccer matches, or big races on the national or international stage, is huge. It’s far less so for a Tuesday maiden at Swan Hill.

Betfair: Commission

They haven’t actually set up this worldwide market and gone around matching everybody’s bets just because they’re good blokes!

Betfair makes money off all bets, but they’re not a traditional bookmaker, so they don’t do it in the same way.

They do this by charging a commission on all winnings. Your commission charge is a percentage of any profit you make on a bet: on most markets worldwide it’s 5%, however on others it’s higher due to license fees they have to pay sport or racing bodies.

And yes, you guessed it, that includes Aussie racing! Check out the Betfair Hub for current commission rates.

You aren’t charged Commission on the total collect, only on the profit. And there’s no commission on losing bets – the winner pays that!

You can get a discount on the commission: Betfair has a loyalty scheme where you earn points based on how much betting you do. The more points you have, the higher your discount.

On the other side of the coin, the most profitable punters pay a “high roller tax” on all profits above a certain amount. That’s hopefully a problem you’ll have in the future, but if you’re just starting out it’s a long way off!

Right, that’s the basics… let’s look at things in more depth.
