Thunder Snow won the Dubai World Cup for trainer Saeed bin Suroor on a stunning night at Meydan for Sheikh Mohammed's Godolphin team.
Jockey Christophe Soumillon took the 8-1 shot into an early lead and he surged clear to claim the $10m (£7.1m) prize.
Favourite West Coast, trained by Bob Baffert, just took the runner-up spot from stablemate Mubtaahij.
Godolphin also celebrated wins on the world's richest racecard with Hawkbill, Benbatl and Jungle Cat.
Newmarket trainer Bin Suroor was saddling his eighth World Cup winner, while it was a first for Soumillon, who won by five lengths on Thunder Snow.
"I don't know if it was Sheikh Mohammed's daughter, but there was a little girl before the race who said to me 'it's a small track, so if you go in front you're going to win it,'" said Soumillon.
Bin Suroor also scored in the Dubai Turf, thanks to the Oisin Murphy-ridden Benbatl.
