Godolphin have confirmed the retirement of two of their star colts, Tentyris and Observer, to stud.

The duo is being sent to the Darley stallion roster for the 2026 breeding season.

Tentyris retires with two Group 1 wins next to his name - the 1200m Coolmore Stud Stakes and 1000m Lightning Stakes. In fact, he became only the fourth three-year-old colt to win the Lightning in the past 25 years.

Observer also retires with two Group 1 victories, coming in the 2500m Victoria Derby and 1600m Australian Guineas.

The Godolphin duo amassed over $5 million in prize money, combined.

Godolphin has announced the retirement of Tentyris and Observer to the Darley stallion roster for the 2026 breeding season. Both played leading roles in a season that has so far delivered 30 Stakes wins, including 11 at G1 level

Tentyris (Street Boss) retires as the leading sprinting colt of his generation. Victorious in the G2 Todman Stakes at two and runner-up in the G1 Blue Diamond Stakes, he returned at three for dual successes at the highest level.

He recorded the fastest time in the history of the G1 Coolmore Stud Stakes before adding the G1 Lightning Stakes at weight-for-age. In doing so, he became only the fourth three-year-old colt to win the Lightning Stakes in the past 25 years.

By Street Boss, out of an Exceed And Excel mare from the family of Divine Madonna, Tentyris is bred on a similar cross to Anamoe. He will stand at Kelvinside in New South Wales at a fee of $88,000 inc GST.

Observer (Ghaiyyath) retires as a dual G1 winner of the Australian Guineas and Victoria Derby. A metropolitan winner as a two-year-old, he was also victorious in the G2 Moonee Valley Vase and G2 Autumn Stakes. A four-time Stakes winner from 1,400m to 2,500m, he retires with earnings of $2.7 million.

He is the best-performed son of Ghaiyyath to retire to stud to date. Out of a full sister to Champion and successful sire Pierro, Observer offers a strong outcross pedigree. He will stand at Northwood Park in Victoria at a fee of $33,000 inc GST.

Godolphin Australia Managing Director Andy Makiv said the results reflected the people behind the horses.

“Tentyris and Observer are two of the best from our amazing three-year-old crop,” Makiv said.

“This season is a credit to everyone involved, from those on the farms to our people in the office, right through to the trainers and their staff.

“To be so competitive on the racetrack this season and win races like the Coolmore, Lightning, Guineas and Derby is something everyone at Godolphin should be very proud of.”
