What is dutching in betting?
Dutching is a staking method where you back two or more selections in the same event and size each stake so that your profit is identical whichever of them wins.
Sometimes you can’t split two runners. You’re sure one of them wins, but not which. Dutching lets you back both, or three, or four, as if they were a single selection with a single price.
The trick is to give more money to the shorter price and less to the longer one, in proportion to each one’s implied probability. The term is used the same way in the UK and the US, and it’s most at home in horse racing, where fields are big.
Example
A race. You like two horses, at 4.00 and 6.00, and want to stake $50 in total.
- Implied chance of each: 1 ÷ 4.00 = 25%, and 1 ÷ 6.00 = 16.67%. Together: 41.67%.
- Stake on each = total stake × its share.
- Horse A: 50 × 25 ÷ 41.67 = $30
- Horse B: 50 × 16.67 ÷ 41.67 = $20
- Check: $30 × 4.00 = $120. $20 × 6.00 = $120.
Either horse wins and you get $120 back, a $70 profit. Your combined odds are 120 ÷ 50 = 2.40. If anything else wins, you lose the full $50.
Watch out
Dutching doesn’t create value. It only reshapes it. You’ve turned a 4.00 shot and a 6.00 shot into one 2.40 shot, and you’re paying the bookie’s margin on both bets. If neither price was good on its own, the dutch isn’t good either.
It gets confused with arbitrage, which covers every outcome across different bookies. A dutch leaves outcomes uncovered, so it can lose.
It only makes sense when you’d happily back each selection alone. Most bet calculators have a dutching mode, so you don’t need to do the arithmetic by hand.
