Meghan Markle's baby bump has prompted punters to put money behind the Duchess of Sussex having twins.

Sportsbet.com.au said the initial odds of Meghan and Prince Harry giving birth to a twin were sitting on NZ$23, but have since moved into NZ$14 on their site.

Spokesperson Will Byrne said "punters have responded to Meghan's booming baby bump with a few punts placed on twins".

He said one punter even placed a dollar on quintuplets - a bet that would pay out NZ$1085.

The British royal family has not had twins for 588 years  the last being born in the 15th Century, when Queen Joan of Scotland had twin boys.

Scientists predict only 2 percent of the world's population to be twins, with just 0.2 percent of the identical variety.

Bets on Meghan giving birth to a girl have attracted three times more money than a boy, and Diana is leading in the list of names, on NZ$9.76.
