A SHARE in leading sire Siyouni headlines the catalogue for the Tattersalls Online December Sale, for which bidding opens on December 10th and closes on December 11th. The successful buyer of the share will receive one nomination to the stallion in 2026, two nominations in 2027 and in every other year thereafter.

The Haras de Bonneval resident will command €150,000 in 2026, following a year in which he sired 19 group performers in the Northern Hemisphere, matching his previous best. Zarigana was the highlight of the year, gaining Group 1 success in the French 1000 Guineas. Beaten a nose in the Prix Marcel Boussac as a juvenile, the Aga Khan home-bred gained further Group 1 blacktype when finishing second in both the Coronation Stakes and Prix de la Foret.
