Arbitrage Betting vs Hedging vs Matched Betting: How They Really Differ

By the AUOdds team · Updated 19 Oct 2026 · 7 min read

Key takeaways
  • Arbitrage covers every outcome from the start at prices that lock in a return at the prices shown, provided every bet stands.
  • Hedging begins with a bet you already hold and only locks a return when the earlier price was good enough; otherwise it just reduces risk.
  • Matched betting relies on promotions such as bonus bets, so the value comes from the offer rather than from prices disagreeing.
  • All three carry real risks: prices move, stakes get limited, bets can be voided and calculation mistakes happen.
  • Use only licensed Australian bookmakers, place every bet before the event starts, and treat betting as entertainment first.

Arbitrage betting vs hedging is a comparison that confuses many Australian punters, because both involve backing more than one side of the same event. Add matched betting and the terms start to blur together. They are not the same thing. Each starts from a different place, costs a different amount and carries a different set of risks. This guide puts the three side by side and works through one example of each with real-looking decimal odds and stakes. It shows when a return is locked in at the prices shown, when you are only reducing risk, and what bonus bets change. It also covers the risks that apply to all three. There are no promises of easy income here, just the maths and the trade-offs.

What is the real difference in arbitrage betting vs hedging?

The difference comes down to timing and certainty. An arbitrage, often called a lock, is built from scratch. You back every possible outcome of an event at different licensed bookmakers, and the prices add up to less than 100% implied probability. If every bet stands at the prices you took, the return is the same whichever side wins.

Hedging starts from a bet you already hold. You place an opposing bet later, usually because the price on your original pick has moved or because a multi is one leg from landing. The aim is to make the result matter less to you. Sometimes a hedge locks in a return across every outcome. Often it only narrows the gap between your best case and your worst case.

Matched betting sits alongside both. It uses bookmaker promotions, mostly bonus bets, and covers the other outcomes with cash bets. That turns the bonus into a smaller but more predictable amount. Without the promotion, the same pair of bets would usually lose a little.

The quickest way to tell them apart is to ask one question: where does the edge come from?

Once you know the source of the edge, you know what can go wrong. That is the part most comparison pages skip.

How do arbitrage, hedging and matched betting compare side by side?

Here is the comparison in one place. Read each line across the three methods.

One point applies to all three. Every bet should be placed before the event starts, with licensed Australian bookmakers. Online in-play sports betting isn't offered to Australians, so a plan that depends on betting mid-game isn't one to follow.

What does a true arbitrage lock look like in practice?

Take a tennis match with two outcomes. Bookmaker A offers Player 1 at 2.10. Bookmaker B offers Player 2 at 2.02.

Convert each price to implied probability by dividing 1 by the odds:

Because the total is under 100%, the prices form a lock of roughly 2.96%. To split a $500 total stake so that each outcome returns the same amount, divide each implied probability by the total:

Whichever player wins, the return is about $514.80, roughly $14.80 ahead of the $500 outlay. That is a return locked in at the prices shown. It is not money in the bank until both bets are accepted at those prices and the market settles normally.

Note how thin the margin is. AUOdds data from the last 30 days shows 2,919 locks with a typical size of 1.6%, across 9 bookmakers and about 15,000 prices tracked at any moment. This example is better than typical. At 1.6%, the same $500 would lock in about $8.

That is why speed and accuracy matter so much. Prices are often only about 10 seconds old when you see them, and a price that shifts from 2.10 to 2.02 before your first bet is accepted can turn a lock into a small loss. A wrong stake typed into one bookmaker can do the same.

When does hedging lock a return, and when does it only reduce risk?

Hedging depends on what you already hold. Say you have a $20 four-leg multi at combined odds of 15.00, so it returns $300 if it lands. Three legs have won. The last leg is a basketball match later that evening, and your team is in the multi. A licensed bookmaker offers the opponent at 2.30. You place any hedge before that match starts.

Full hedge. Stake enough on the opponent to equalise the outcomes: $300 / 2.30 = $130.43.

That locks in a return at the prices shown, but only because the first three legs did the heavy lifting. The hedge itself was a fair-priced bet. It didn't create value. It converted a position you already had.

Partial hedge. Stake $60 on the opponent instead.

Both outcomes are positive, but they are no longer equal. You have reduced risk rather than locked it.

Hedging can also lock in a loss. If you backed a team at 1.80 and its price later drifted, covering the other side may only shrink the loss. Each hedge also pays the bookmaker's margin again. Hedging every bet you place tends to wear away value over time, so treat it as a tool for specific situations, not a habit.

Arbitrage betting vs matched betting: what do bonus bets change?

The comparison of arbitrage betting vs matched betting turns on one thing: matched betting needs a promotion, and arbitrage doesn't. Bonus bets change the maths because, commonly, only the winnings are paid and the bonus stake isn't returned. Always check each offer's terms, because they differ.

Here is a worked example. You hold a $50 bonus bet. In a two-way market, Bookmaker A has Team 1 at 3.00, and Bookmaker B has Team 2 at 1.45.

The outcomes:

The $50 bonus has been turned into about $31, or roughly 62% of its face value. Choosing a longer price for the bonus bet usually improves that percentage, because more of the bonus's value ends up in the winnings.

Compare that with arbitrage. A lock needs the prices themselves to disagree, and it can repeat while they do. Matched betting can use ordinary prices, but it is capped by how many promotions you receive and what their terms allow. Common traps include minimum odds, expiry dates, eligible markets and turnover rules.

Neither method is a way to get something for nothing. Both depend on bets standing as placed and on accounts staying open.

What risks apply to all three, and what should you check first?

Whichever method you use, the same practical risks apply. Run through this checklist before you commit money.

Tools help with the arithmetic, not the judgement. AUOdds alerts members to locks with the exact stake for each outcome, but you still decide whether to act and you place every bet yourself.

Frequently asked questions

Is hedging the same as arbitrage betting?

No. Arbitrage covers every outcome from the start at prices that lock in a return at the prices shown. Hedging adds an opposing bet to a position you already hold. A hedge only locks a return when your original price was good enough. Otherwise it narrows the range of results, and it can even lock in a smaller loss.

Is matched betting better than arbitrage betting?

Neither is better in every case. Matched betting depends on promotions such as bonus bets, so it is limited by how many offers you receive and their terms. Arbitrage depends on prices disagreeing between bookmakers and needs speed. Both face stake limits, voided bets and human error, so neither should be treated as reliable income.

Can I hedge a bet while the game is being played?

Online in-play sports betting isn't offered to Australians by licensed bookmakers, so plan any hedge before the event starts. For a multi, that means placing the hedge before the final leg begins. If you missed that window, accept the bet as it stands rather than looking for workarounds.

Do I pay tax on arbitrage or matched betting returns in Australia?

The ATO explains that gambling winnings are generally not assessable for most people. Its ruling IT 2655 discusses when betting activity may be treated as a business. Your circumstances matter, so if you bet frequently or at large scale, speak with a registered tax agent rather than relying on general information.
