An exciting new chapter begins with the arrival of three homebred Group 1 winners.

The winner of four Group 1 races from nine to 12 furlongs, Daryz brought his racing career to a close by becoming the first colt in nearly 50 years to win back-to-back renewals of the Prix de l’Arc de Triomphe. This remarkable son of Sea The Stars and Group 1 winner Daryakana, whose defining racing attribute was his terrific turn of foot, will stand at Gilltown Stud alongside his leading sire at an introductory fee of €50,000.

Rayif and Samangan will join the team at Haras de Bonneval.

A Group winning and Group 1-placed juvenile, Rayif enhanced his reputation at three by becoming the first horse in 25 years to complete the Poule d’Essai des Poulains–Prix Jacques Le Marois double. This specialist miler was last seen finishing third, recording the fastest closing sectionals, in the Queen Elizabeth II Stakes at Ascot.

He will commence his stallion career at a fee of €20,000.

Samangan is the fastest and most precocious colt produced by the Aga Khan Studs since Siyouni.

A son of Blue Point out of an Oasis Dream mare, he excelled at an early age as a dual Group winner over six furlongs at two, before adding the six-and-a-half-furlong Prix Maurice de Gheest to his tally at three.

He will stand at a debut fee of €10,000.

Sea The Stars enjoyed another exceptional season in 2026, with four Group 1 winners capped by the exploits of dual Prix de l’Arc de Triomphe hero Daryz alongside Aventure, Johanna Walsh and Maltese Cross. He also achieved a career-best number of two-year-old Stakes winners, with four to date including Group winners Alpha and Wall Street and Group 1-placed Quest For Stars. Further underlining his impact on the stud book, Sea The Stars was also the broodmare sire of five Group 1 winners this year, among them Epsom Derby hero Christmas Day, Prix du Moulin de Longchamp winner Erdenali and Prix Marcel Boussac heroine Green Empress.

Having concluded October as Europe's second-leading sire, Sea The Stars will stand at the unchanged fee of €300,000 in 2027.

Siyouni continues to strengthen his reputation as one of Europe's foremost sources of Classic winners, with more European ‘Guineas’ winners to his name than any other active stallion. He added further to his tally in 2026 in the shape of Preis der Diana winner Soreanga. This season also saw him surpass the landmark of 100 career Stakes winners, and he ended the season as a top five sire by percentage of Stakes winners to runners. His latest wave of talent includes juvenile Stakes scorers Algebre, Gymbaazy, Vignelli and Zakkan, while his yearlings continued to prove popular in the sales ring, where he was responsible for two of the 10 seven-figure yearlings sold at the Arqana August Sale. He achieved a 2026 yearling average of over €275,000 across the European sales.

Siyouni will stand at a reduced fee of €110,000 in 2027.

Zarak has become well renowned for his impressive statistics ever since his first crop, conceived at a fee of €12,000, hit the track. The sire of 14 Group 1 horses, he has a lifetime Stakes winners to runners ratio consistently in excess of 11% and a Stakes horses to runners figure of over 17%. In 2026, his representatives included the progressive Group 2 winner Varandir, Group winner and Classic-placed James J Braddock and multiple Stakes winners Flatten The Curve, Stingray and Zakopane. A promising group of two-year-olds included several black-type performers including Zarak Pasha, recently second to Wall Street in the Gr.3 Eyrefield Stakes, the pair pulling six and a half lengths clear of their rivals.

With his first crop conceived at an increased fee of €60,000 set to turn three in 2027, Zarak has every opportunity to continue his upward trajectory. His fee remains unchanged at €80,000.

Next year will also mark an important milestone for two exciting young stallions, with the first runners by Vadeni and Erevann set to reach the racecourse.

Champion Three-Year-Old Vadeni, who completed an exceptional Group 1 double in the Prix du Jockey Club and Eclipse Stakes at three, was also a Stakes winning juvenile, so his first runners are particularly anticipated. At the sales this year, his first yearlings made up to 400,000gns, averaging almost €60,000 for 37 sold. Vadeni will remain at €15,000 in 2027.

Erevann, a son of Dubawi and triple Group 1 heroine Ervedya, will relocate to Gilltown Stud following three seasons covering full books of mares at Haras de Bonneval. The Group 2 winning miler’s first yearlings brought up to €215,000 in the sales ring, with 50 sold for an average of over five times his stud fee. For his debut Irish season, Erevann will remain at €8,000.
