Taghrooda has dramatically firmed to win the Prix de l'Arc de Triomphe following her stunning victory in the King George VI and Queen Elizabeth Stakes.
The filly took on the older horses in the Group One race and beat Mukhadram by three lengths to become the first filly since Pawneese in 1976 to win the summer showpiece at Ascot.
Her owner Sheikh Hamdan Al Maktoum made the call to bypass the Irish Oaks and target the King George.
Trainer John Gosden hinted immediately after the race that the Yorkshire Oaks and the Arc in October were the two logical races before she was retired to stud at the end of the season.
A 12-1 chance for the Arc before the King George, Taghrooda is at 9-2 with Paddy Power but was cut to 3-1 by Ladbrokes and 7-2 by William Hill.
"The hint from Sheikh Hamdan's racing manager on Saturday that the owner might want to have a go at the Arc has been taken on board by punters, who have really got stuck into the filly," a Paddy Power spokesman told the Racing Post.
German Derby winner Sea The Moon, last year's Arc winner Treve and dual Classic winner Australia are next at around 6-1.
