Despite his defeat at Longchamp Polytain was again stepped up in class for the 155th running of the Prix du Jockey Club over 2400 Metres at Chantilly Racecourse on 7 June in which he was ridden or the first time by Frankie Dettori and started a 36.5/1 outsider. His sixteen opponents included Break Bread, Johann Quatz (winner of the Prix Lupin) Apple Tree (Prix Greffulhe), Adieu au Roi (Prix Hocquart), Grand Plaisir (Prix Noailles), Silver Kite (Prix Yacowlef), and Jape (Premio Guido Berardelli). Dettori restrained the colt in the early stages and reached the final turn in twelfth place. He made steady progress in the straight, caught the André Fabre-trained Modhish approaching the last 200 metres and was driven clear to win by one and a half lengths. Marignan finished second ahead of Contested Bid, Johann Quatz and Modhish.
