To bring that into perspective, that’s three times more than the £3 million cashed in during the lead up to the births of Prince George, Princess Charlotte and Prince Louis of Cambridge.
But it seems Sussex baby is taking after his or her parents, as the betting phenomenon can only be compared to the royal wedding on May 19, 2018. For the Windsor nuptials, fans forked out more than £3.5 million in bets.
Punters have predicted that Harry and Meghan will name their baby Diana, a touching homage to the late Princess Diana, following a flurry of bets on the newborn being a girl.
If the couple welcome a son, Arthur, James and Edward are all front-runners.
Harry and Meghan are no strangers to breaking records. Their new Instagram account, @sussexroyal, amassed over 8,000 followers just six minutes after launching – boasting one million within six hours.
