So You Think was a dark bay or brown stallion foaled in New Zealand on 10 November 2006. He was bred by Mike Moran and Piper Farm and foaled at Windsor Park Stud in Cambridge.

He was by High Chaparral, the Epsom Derby, Irish Derby and dual Breeders’ Cup Turf winner who became one of the most influential European stallions used in Australasia. So You Think developed into his most celebrated racing son.

His dam, Triassic, was a Group 2-winning daughter of Tights who won from 1400 to 2000 metres. She produced nine winners from ten named foals and was named New Zealand Broodmare of the Year in both 2010–11 and 2011–12.

The pedigree combined the stamina and international class of Sadler’s Wells through High Chaparral with the speed and toughness of an established New Zealand female family. So You Think inherited considerable size and presence, standing approximately 16.3 hands and carrying an almost black coat that made him immediately recognisable.

So You Think was offered by Windsor Park Stud at the 2008 New Zealand Bloodstock Karaka Premier Yearling Sale. Duncan Ramage of DGR Thoroughbred Services purchased him for NZ$110,000 on behalf of Malaysian owners Dato’ Tan Chin Nam and Tunku Ahmad Yahaya.

The purchase reunited Dato’ Tan with Bart Cummings, the trainer responsible for many of his greatest horses. Although the price was respectable, it gave little indication that the colt would eventually become a ten-time Group 1 winner and one of Karaka’s most internationally successful graduates.

Following his second Cox Plate and third-place finish in the 2010 Melbourne Cup, a controlling interest was sold to Coolmore. The precise value was never publicly confirmed, although contemporary reports placed it among the largest private transactions involving an Australasian racehorse.

The agreement allowed Dato’ Tan to retain an interest but moved So You Think from Australia to Coolmore’s Ballydoyle operation in Ireland. The sale divided opinion in Australia because it ended his association with Bart Cummings at the height of his local dominance, but it also created the opportunity for him to prove himself across Europe, Dubai and the United States.

So You Think made his debut at Rosehill in May 2009, winning a restricted 1400-metre race. It was his only appearance at two and the beginning of an unusually rapid rise through Australian racing.

So You Think retired to Coolmore Australia in 2012, beginning his stud career at a service fee of A$66,000. He reverse-shuttled to Coolmore Ireland for four Northern Hemisphere seasons before remaining permanently in Australia.

His early progeny took time to mature, much as he had, but his reputation strengthened as they reached three and four. His runners demonstrated unusual versatility, producing Group 1 winners from sprinting distances through to the 3200-metre Sydney Cup.

Among his leading progeny were Think It Over, Think About It, Knights Order, Quick Thinker, Nimalee, D’Argento, Sopressa, Palaisipan, La Bella Diosa and Nakeeta Jane. In April 2022, he produced three Group 1 winners on a single afternoon at Randwick through Knights Order, Nimalee and Think It Over.

He finished among Australia’s ten leading sires in each of his final five completed seasons and twice finished second in the national sires’ premiership. His service fee reached a career high of A$99,000 in 2023.

So You Think was inducted into the New Zealand Racing Hall of Fame and the Australian Racing Hall of Fame. He became one of Coolmore Australia’s most popular public-facing stallions, remembered by staff as an intelligent and exceptionally gentle horse.

He died on 20 October 2025 at the age of 18 after a short illness, despite receiving treatment at Scone Equine Hospital. At the time of his death, he had sired 66 stakes winners and 12 individual Group 1 winners, with further crops still to race.
