In October 2017 the yearling was offered for sale at Tattersalls and was bought for 200,000 guineas by the bloodstock agent Charlie Gordon-Watson[2] of behalf of John Magnier's Coolmore Stud organisation.

He is from the first crop of foals sired by No Nay Never, an American horse who had his greatest success in Europe where he won the Norfolk Stakes and the Prix Morny as a juvenile in 2013.

After tracking the leaders he went to the front in the last quarter mile and held off the sustained challenge of Jash to win by half a length, with the pair coming home well clear of the rest.

Ridden by Moore he started favourite again, but despite making steady progress in the closing stages he never looked likely to win and finished fourth behind Advertise.

Advertise started favourite, while the other contenders included Pretty Pollyanna, Fairyland, Limato and Cape Byron (Wokingham Stakes).

Racing down the centre of the track, Ten Sovereigns disputed the lead from the start and drew away from his opponents in the closing stages to win by two and three quarter lengths.

[14] After the race Aidan O'Brien commented "We knew he was very good from last year but we trained him for a Guineas and he hadn’t really clicked into sprinting at Ascot.

[15] At York Racecourse on 23 August Ten Sovereigns was dropped back to five furlongs and started 13/8 favourite for the Nunthorpe Stakes but after tracking the leaders he faded in the closing stages and finished sixth of the eleven runners behind Battaash.
