Dual 2000 Guineas winner Gleneagles heads a field of six for the St James's Palace Stakes at Royal Ascot on Tuesday.
The Aidan O'Brien-trained colt looked a cut above his rivals in picking up both Classics at Newmarket and the Curragh.
He appears to have frightened away plenty of opposition but has not scared off Poule d'Essai des Poulains hero Make Believe.
The Andre Fabre-trained colt, who was supplemented at a cost of £35,000, had his form boosted by the victory of his stablemate and Poulains runner-up New Bay in the Prix du Jockey Club.
Make Believe's owner Prince Faisal also retains an interest in Belardo, with Godolphin buying into last season's champion two-year-old.
Trainer Roger Varian is praying there is still time for showers to hit the Berkshire course.
"Belardo is a big price, but we are hoping for thunderstorms to come. The horse is in super form and has come on for his run in the Irish Guineas," said Varian.
"He probably had the worst run of the race as he missed the break, then he had to loop around the field."
Michael Stoute has an interesting contender in Consort, who is taking a big hike in class after winning his two starts, most recently in the Heron Stakes at Sandown.
Hugo Palmer's Solario Stakes scorer Aktabantay makes his belated seasonal debut, while Godolphin's Latharnach, trained by Charlie Appleby, completes the sextet.
