Second place in the 11-strong field went to lone US raider Harlan’s Holiday, the mount of John Velazquez with hot favourite Nayef, ridden by Richard Hills, in third.
It was a third win on the night for Dettori who had earlier triumphed for Godolphin and trainer Saeed bin Suroor in the Godolphin Mile and the Sheema Classic.
It was also the Italian’s second World Cup following Dubai Millennium in 2000. Godolphin, brainchild of Sheikh Mohammed of Dubai, have now won three of the last four World Cups and trainer bin Suroor four out of the last five.
Moon Ballad, 11-4 second favourite in London betting behind Nayef at 11-8, was always in the first two and once he took up the running early in the straight the colt waltzed away and won easily.
Harlan’s Holiday, 11-2 in betting in Britain, stayed on gamely and held on to second by a length from Nayef.
Moon Ballad’s victory brought back memories of Dubai Millennium who decimated his field three years ago to win by six lengths in record time.
The four-year-old raced home just over half a second slower but it was an awesome performance by a horse who is still improving.
That includes the Breeders’ Cup Classic in the United States in October for which Moon Ballad has already been installed 6-1 favourite by British bookmakers.
The colt finished third in last year’s Epsom Derby but then broke the track record at Goodwood and ran a good second in the Newmarket Champion Stakes. A six length success in a race at Nad Al Sheba last month had advertised his chances and Dettori deserted last year’s world series champion Grandera to partner Moon Ballad.
The ride on Grandera went to Jamie Spencer but the pair could do no better than fourth on Saturday, just over six lengths off the winner.
The World Cup was the final event at a seven-race meeting carrying total prize money of $15.25 million, making it the sport’s most valuable single day.
Others were in good form too, apart from the Godolphin-bin Suroor-Dettori axis.
Michael Hills in the Golden Shaheen and twin brother Richard in the event for Arabian purebreds both recorded valuable wins and South African trainer Mike de Kock landed a double with Victory Moon in the UAE Derby and Ipi Tombe in the Dubai Duty Free.
They were the first winners from South Africa and the southern hemisphere in the eight years of the World Cup meeting, although both have been stabled in Dubai this year.
The meeting went ahead without incident despite concerns over the war in Iraq.
