Background Silver Sonic is a grey stallion bred in Chitose, Hokkaido, by Shadai Farm. He was sired by Orfevre, a son of Stay Gold, and his dam was Air Toule, a grey mare by Tony Bin who won the Hanshin Himba Stakes. He was owned by Shadai Race Horse and trained by Yasutoshi Ikee at the JRA's Ritto Training Center. His half-brother Captain Toule (by Agnes Tachyon) won the Satsuki Shō, and his half-sister Ultimo Toule (by Fuji Kiseki) won the Centaur Stakes and the Silk Road Stakes. His granddam Ski Paradise won the Prix du Moulin de Longchamp and the Keio Hai Spring Cup.

He was nicknamed "Silvie" by his groom, Keita Ikemoto.

Racing career 2019: three-year-old season Silver Sonic did not race as a two-year-old. He debuted on 20 January 2019 in a 3-year-old newcomer race over 1600 metres on turf at Kyoto Racecourse, finishing second. After two further second-place finishes, he won his maiden race on 2 June at Hanshin Racecourse. He then won the Kunisaki Tokubetsu on 27 July and the Hyogo Tokubetsu on 29 September, recording three consecutive wins.

2020: four-year-old season He ran four times in 2020 without winning, recording a third-place finish in the Karasuma Stakes as his best result.

2021: five-year-old season Silver Sonic began the year with unplaced and minor finishes in allowance races. On 12 June, he won the June Stakes at Tokyo Racecourse, entering the open class. After a sixth-place finish in the October Stakes, he contested the Stayers Stakes (GII) on 4 December at Nakayama Racecourse, his first graded stakes start, and finished third behind Divine Force.

2022: six-year-old season He began the year with third-place finishes in the Manyo Stakes and the Hanshin Daishōten (GII). On 1 May, he contested the Tennō Shō (Spring) (GI) at Hanshin. He stumbled shortly after the start, unseating jockey Yuga Kawada. He continued to run riderless, passing the post second behind the winner Titleholder, before tripping over the outer rail. He sustained only minor abrasions.

He missed the remainder of the season with a splint bone injury in his left foreleg. After being excluded from the Copa Republica Argentina by ballot, he returned on 3 December in the Stayers Stakes at Nakayama. Ridden by Damian Lane, he advanced along the inside rail in the straight and won by 0.1 seconds from Plume d'Or, recording his first graded stakes victory. The win was the 800th JRA victory for trainer Yasutoshi Ikee.

2023: seven-year-old season On 25 February, Silver Sonic contested the Red Sea Turf Handicap (G3) at King Abdulaziz Racetrack in Saudi Arabia. Ridden by Damian Lane, he took the lead at the entrance of the straight and won by 2.5 lengths from Enemy, recording his first overseas victory. The win made him the third consecutive generation of his sire line, after Stay Gold and Orfevre, to win a graded stakes race outside Japan. On 30 April, he ran in the Tennō Shō (Spring) at Kyoto, finishing third behind Justin Palace and Deep Bond. A planned autumn campaign in Australia, including the Melbourne Cup, was cancelled after swelling in his left fetlock, and he did not race again that year.

He ran in the Hanshin Daishōten on 17 March, finishing 11th, and in the Tennō Shō (Spring) on 28 April, finishing 16th. He was subsequently diagnosed with severe suspensory ligament inflammation, and his retirement was announced on 26 May 2024.
