Quddwah won Sunday's Group 3 Prix Messidor at Chantilly and was clipped in the betting for Goodwood's Celebration Mile as a result.
Trained by Simon and Ed Crisford for Sheikh Ahmed Al Maktoum, the five-year-old joined Diego Velazquez as another subsequent winner to emerge after being well held in last month's Queen Anne Stakes at Royal Ascot.
Quddwah, sent off the 9/4 favourite in the hands of Callum Shepherd, showed a smart turn of foot to quickly put daylight between himself and his rivals before going on to score by two and a half lengths from 50/1 chance Geography, with 5/2 shot Ridari back in third.
Quddwah was trimmed to 14/1 from 25s by Paddy Power for the mile Group 2 at the Qatar Goodwood Festival.
Earlier on the same Chantilly card, Joseph O'Brien took the GOFFS Prix Robert Papin (Group 2) courtesy of Albany Stakes also-ran Green Sense (4/1), who prevailed by a neck from the Karl Burke-trained Super Soldier in second and Archie Watson's Tadej in third.
Shepherd said on Sky Sports Racing: "He's an easy horse to ride now, he super-relaxed and he does feel like he's star-gazing a bit in front but he was very much the best.
"I do (think he's still improving), I certainly thought at Longchamp at the start of the year that he'd returned a much better model and Ascot was very forgivable, the ground was too quick and a very hot day. Sometimes those things can play a part.
"So it was a real return to form here, he enjoyed getting his toe in and he's up there with the best of them when he get the circumstances his way. It would be great to win a Group 1 with him, he is capable of it I think."
