As a four-year-old, Moon Madness began by finishing fourth to Mtoto in the Brigadier Gerard Stakes and then finished third in the Hardwicke Stakes at Royal Ascot behind Orban. He recorded his most important victory of the season in France, winning the Grand Prix de Saint-Cloud from the future Prix de l'Arc de Triomphe winner Tony Bin. He returned to England to contest the King George VI and Queen Elizabeth Stakes, but finished unplaced behind Reference Point. In August, Moon Madness won the Geoffrey Freer Stakes, beating a field which included Legal Bid and Ibn Bey (runner-up in the Breeders' Cup Classic).
