The top ten most expensive sires in the world for 2017 offers an insight into the international nature of the sport.
The top four spots are held by Galileo, Dubawi, Tapit and Deep Impact, stallions based in Ireland, Newmarket, Kentucky and Japan.
That quartet are established leaders of their respective domains, as are War Front and Medaglia d’Oro.
But the list for 2017 also includes two new American names who are gaining great traction in Curlin and Uncle Mo, both of whom have been increased to $150,000.
Curlin sired five G1 winners this year alone, while Uncle Mo is a top-three American sire despite having only two crops to run for him.
In Europe, the younger generation is spearheaded by Frankel, arguably the greatest European runner of the modern era. There was tremendous hype surrounding his first runners and he hasn’t disappointed, firing in six stakes winners out of his first crop.
