Sheikh Mohammed has bought into Dubai World Cup winner Animal Kingdom, acquiring a 29 per cent share.
It means Animal Kingdom will stand in the northern hemisphere at Darley's Jonabell Farm in Kentucky.
John Messara, who bought 75 per cent of Animal Kingdom from Team Valor before the World Cup, will stand him at Arrowfield Stud in the southern hemisphere.
"Animal Kingdom is outstanding," Darley chief operating officer Oliver Tait said.
"Not only is he immensely talented, he has shown a rare ability to excel on turf, synthetic and dirt and win at a range of distances up to the mile and a quarter (2000m) of the Kentucky Derby and the Dubai World Cup.
"His win at Meydan last Saturday was all class."
Messara said he was pleased to be a partner with Darley.
"We are delighted to partner with Darley in the ownership of Animal Kingdom and management of his future international stud career," Messara said.
"We have always had a great working relationship with Darley and have the utmost respect for Sheikh Mohammed and the Darley management team.
"With our unprecedented combined support Animal Kingdom will have every opportunity to develop from a champion racehorse into a champion sire."
The World Cup win took Animal Kingdom's career earnings to $US8.3 million ($A7.97 million).
Immediate plans are for Animal Kingdom are to travel to England, with the Group One Queen Anne Stakes or the Group One Prince of Wales's Stakes at Royal Ascot as possible engagements.
