Alexander, James and Arthur are currently leading the way at bookmakers as royal fans and gamblers alike are placing bets on what Prince Harry will name his son.
After Meghan, the Duchess of Sussex gave birth yesterday morning to a boy, punters have been rushing to bookies to make a quick buck.
Coral has Alexander at the top of the list, although there has also been a flurry of bets placed on Spencer - the maiden name of Prince Harry’s mother Diana.
John Hill of Coral said: "Following a flurry of bets last evening, Alexander is now the new favourite at the top of our name betting and the one we are fearing the most."
Alexander is 4/1 at Coral, while Arthur is 6/1, and Albert, James and Spencer are all 8/1.
"The interesting name which we have taken plenty of money on is Spencer as we did not lay a single bet on this name before the Duchess of Sussex gave birth," Mr Hill added.
Harry said he and Meghan are still deciding on a name.
As he announced the birth at Windsor, he added: "Still thinking about names. The baby is a little bit overdue, so we've had a little bit of time to think about it."
At Paddy Power, Alexander and James are joint favourites at 7/2, followed by Arthur at 6/1, and Oliver at 12/1, which has fallen swiftly from 33/1 following the baby's birth.
William Hill has Arthur at 4/1, James and Alexander at 5/1, Albert at 10/1 and Philip at 11/1.
Spokesman Rupert Adams said: "We have had the first significant move since the announcement and Alexander has been halved in price from 10/1 to 5/1."
Coral's outside odds include Apple at 200/1, Boris at 250/1 and Donald at 1000/1.
The baby, who is seventh in line, is 2-1 to become an actor, and 500-1 to end up on the throne.
