The Aga Khan Studs are pleased to announce the 2026 stud fees for their roster of five stallions standing in Ireland and France.
Sea The Stars has enjoyed an outstanding year and finishes the season as the leading active Irish-based sire. His three Group 1 winners are headed by Daryz - who followed in the footsteps of his sire to win the Prix de l’Arc de Triomphe - together with Aventure and Sosie, while his strong supporting cast of Group 1 performers include Grand Stars, Map Of Stars, River Of Stars, See The Fire, Sweet William and The Lion In Winter. This success also extended to the sales ring, where his colt out of Crystal Zvezda sold for 3.7 million guineas, a world record price for a yearling in 2025.
As a broodmare sire, Sea The Stars added three more Group 1 winners to his record, bringing his total to 10 and further reinforcing his influence on modern pedigrees. In recognition of these achievements, he will stand for a fee of €300,000 in 2026.
Siyouni continues to be a consistent source of Classic winners, with his record of European ‘Guineas’ winners unmatched by any other active stallion. In 2025, his daughter Zarigana won the Poule d’Essai des Pouliches while Flight finished runner-up in the 1000 Guineas. His international success was spearheaded by Grade 2 winner Bellezza in the USA and Group 2 winner Shin Emperor in Dubai, while his two-year-old crop included Group 1 placed Narissa.
Siyouni is also making his mark as both a sire of sires and a broodmare sire, being the paternal and maternal grandsire respectively of Gr.1 Prix Marcel Boussac winner Diamond Necklace and Gr.1 National Stakes winner Zavateri. He will stand for €150,000 in 2026.
Zarak has been responsible for 12 Group 1 horses to date, with 2025 additions including Grade 2 winner Laurelin, second in the Gr.1 Queen Elizabeth II Challenge Cup, and Campacite, runner-up in the Gr.1 Critérium International. He has become renowned for his exceptional progeny statistics, with 14% of his foals conceived at €12,000 going on to gain black-type and a lifetime Stakes winners to runners ratio consistently in excess of 10%.
Zarak also achieved his highest yearling price to date this year when a filly out of Prudente fetched €1.1 million at the Arqana August Sale – and this crop, two-year-olds of 2026, will be his first conceived at the increased fee of €60,000. He will remain at €80,000 next season.
This spring saw the arrival of the first foals by Champion Three-Year-Old Vadeni and Group 2 winning miler Erevann. Both horses have been well supported by breeders in their first two seasons at stud, covering three-figure books each year, and there is much excitement at the prospect of their first yearlings in 2026.
Vadeni – a record-breaking winner of the Prix du Jockey Club and the Eclipse Stakes – will stand at a fee of €15,000 next season. Erevann – a son of Dubawi out of Siyouni’s three-time Group 1 winning daughter Ervedya, will remain at €8,000.
It was a memorable weekend for Sea The Stars, whose progeny lit up both the racecourse and the sales ring with a new Group 1 triumph and the top price at the BBAG Yearling Sale.
