Aclaim is likely to be found a job at stud following his first Group One success in the Prix de la Foret at Chantilly on Sunday.
The victory capped a breakthrough weekend for his trainer Martyn Meade, who just 24 hours earlier had saddled the first and fourth in the Cambridgeshire with Dolphin Vista and Chelsea Lad.
"It was certainly a weekend to remember," said Meade.
"Of course you dream you can win both races, but you don't really think you'll be fortunate enough for it to actually happen.
"Who could have thought we'd have a weekend like that. You start the season with goals, and most of ours were around Eminent and we had the disappointment of the Derby, but then we end up with a weekend like this."
Aclaim followed up his his win in the Park Stakes at Doncaster, marking him out as a real seven-furlong specialist, and the lack of options at that distance mean he has almost certainly run his last race.
"He certainly won't run again this season and we're just deciding whether he is going to stud or not," said Meade.
"He's worked his way up the ladder, won two Group Twos and now a Group One and while he's versatile having won over a mile and six furlongs as well, he's definitely best at seven.
"What more can he do now? There's only one Group One at that trip and he's won it. I also wouldn't want to see him beaten now."
