Ridden by Noel Fehily, Silviniaco Conti took the lead three hurdles from the finish and won by ten lengths from Captain Chris in "impressive" fashion.
In the Grade 2 Rising Stars Chase at Wincanton in November, he recorded his first victory in a steeplechase, as he started the 8/11 favourite and won by twenty-five lengths from Mad Moose.
[6] In the Grade 1 Feltham Novices Chase at Kempton Park on Boxing Day he finished second behind the favourite Grand Crus, with Bobs Worth in third place.
At Ascot Racecourse in February he started 11/10 favourite for the Reynoldstown Novices' Chase, but finished fourth of the seven runners ten lengths behind the winner Invictus.
[7] Three weeks later in the Grade 1 Lancashire Chase at Haydock Park he was pitted against Long Run, the winner of the 2011 Cheltenham Gold Cup at level weights.
Walsh sent the gelding into the lead two fences from the finish and he drew clear to win by seven lengths from the 2012 Gold Cup runner-up The Giant Bolster.
Starting the 7/2 second favourite he finished third behind Cue Card and Dynaste in a very strong field which also included Bobs Worth, Long Run and Tidal Bay.
He faced Cue Card, Dynaste and Long Run again in the King George VI Chase over three miles at Kempton Park Racecourse on 26 December 2013.
Cue Card led from the start, as at Haydock, but Silviniaco Conti, again ridden by Fehily, tracked the leader closely before taking the lead after the second-last fence.
He held the lead over the final fence and repelled the challenge of Bobs Worth, but was overtaken by a trio of outsiders on the run-in and finished fourth behind Lord Windermere, On His Own and The Giant Bolster.
He settled well in the early stages and jumped quickly; moving alongside the previous year's winner Cue Card turning for home, Conti produced a big leap at four out to send him into the lead.
On a gloomy, overcast day which saw the race run in near darkness the gelding started the 15/8 favourite in a field of ten runner which included Champagne Fever, Al Ferof, Cue Card, Menorah and Dynaste.
Silviniaco Conti increased his advantage in the straight and won by four and a half lengths from Dynaste, with Al Ferof finishing well to deprive Champagne Fever of third place in the final strides.
As in the previous season Silviniaco Conti appeared in the Betfred Bowl at Aintree and started 7/4 favourite ahead of Holywell (Mildmay Novices' Chase, fourth in the Gold Cup), the mare Ma Filleule and Menorah.
[19][20] Three weeks later Silviniaco Conti had his first start over fences of the season in the Betfair Chase, where after making most of the running and an error-free jumping round he was eventually challenged by his old rival Cue Card but couldn't find any more in the home straight finishing 7 lengths in the second place, which took his career winnings past the £1 million mark.
A month later he attempted to win a third consecutive King George VI Chase but after setting the pace for the first and half circuit he began to drop off tamely, eventually being pulled out.
On 20 February Siviniaco Conti contested the Grade 1 Ascot Chase over 2 miles five furlongs and was made the 2/1 favourite against seven opponents including Dynaste, Flemenstar and Triolo d'Alene.
After tracking the leader Royal Regatta until the second last fence, Fehily sent the favourite into the lead and Silviniaco Conti drew well clear to win by twenty lengths.
Due to the small field, Paul Nicholls decided to give Conti a chance of winning his 3rd King George VI Chase in December 2016.
Despite being outpaced turning for home, Silviniaco Conti plugged on gamely to come a gallant 3rd behind the impressive winner Thistlecrack, just a short head behind Cue Card in 2nd.
