Ultra Jackpot is a gelding foaled in 2024, by Cornet Obolensky out of a Cartogran damsire. Another green two-year-old fresh from the rearing fields. He jumps with plenty of scope and has a ground-covering canter. Careful and with a calm character. Still very green, but an interesting horse for the future. Suitable for the amateur, the beginner and the advanced rider.

Cornet Obolensky jumped 1.60m himself and competed at the highest Grand Prix level under Marco Kutscher. At his Westphalian stallion licensing in 2001 he was awarded a 9.24 for jumping and a 10 for free-jumping. He is approved by a large number of studbooks and is considered one of the most influential showjumping stallions in the world; after only four crops he already ranked third on the WBFSH list of best showjumping sires. Well-known offspring include:
Cornado NRW (1.65m, under Marcus Ehning)
Cornet d'Amour (1.60m, under Daniel Deusser)
Cristallo I (1.60m, under Henrik von Eckermann)
Corbinian (World Cup level, under Steve Guerdat)

Damsire Cartogran jumped 1.40m himself, a son of the 1.60m stallion Carthago.

The dam Binessia has already produced two 1.40m showjumpers:
Balcarek (1.40m)
Adorable Heart PS (1.40m)
both half-brothers of Ultra Jackpot.
