The sire to have in your bloodline. Hint Hint.
25 HORSES THAT SHAPED THE SPORT DAY 23 - CORNET OBOLENSKY
Originally named Windows van het Costersveld, this stallion would go on to become one of the most influential sires in modern showjumping history. Cornet Obolensky hasn't just produced winners; he's created a breeding empire that dominates the sport at its highest levels.
He's the 2025 World No. 1 showjumping sire on the WBFSH rankings and his son, Comme il Faut 5, sits at No. 7. With 341 approved sons and 128 offspring competing at 1.60m, his genetic footprint across international showjumping is simply staggering. He was the third most represented sire at the 2018 World Equestrian Games - a testament to how his offspring perform when the stakes are highest.
What makes Cornet Obolensky's dominance so remarkable is its consistency. An extraordinary 31.72% of his offspring are classified as black type, meaning nearly one in three of his progeny compete successfully at the sport's elite level. He doesn't occasionally produce a star; he produces them with clockwork regularity. His offspring possess that rare combination of scope, carefulness, rideability, and competitive drive that defines modern championship jumpers. They're winning Grand Prix competitions from Aachen to LGCT, from Nations Cups to Olympic Games.
His prepotency - that ability to reliably stamp his offspring with his own exceptional qualities - has made him indispensable to breeding programmes worldwide. When breeders want to upgrade their stock, to add scope and technique and that indefinable quality of 'jump,' they turn to Cornet Obolensky.
He represents the pinnacle of what modern sporthorse breeding can achieve: a stallion whose influence extends across generations, whose genetics appear in pedigrees on every continent, and whose name has become synonymous with excellence in showjumping.
