Christopher Tsui, owner of Sea The Stars, feels the colt's career at stud will be as significant as his epic achievements on a racecourse.
The John Oxx-trained three-year-old was earlier this week retired after thrilling racing fans with a series of monumental performances.
Sea The Stars this year secured six Group One wins, including the 2000 Guineas, the Epsom Derby and the Prix de l'Arc de Triomphe.
However, connections opted against letting him have one final foray in next month's Breeders' Cup Classic.
Tsui insists the decision was not taken lightly, and is relishing the next phase of his career.
He told the Guardian: ‘There are, of course, many factors to be considered when retiring a horse from racing.
‘It is also a big responsibility, as Sea The Stars has become so dear to the public.
‘I have of course read opinions of race fans on the internet and I would like to (say) thank (you for) the overwhelming support from most people.
‘There are, of course, some who feel his career was too short and want to see him race more. Some comments were quite nasty, actually, but most were understandable.
‘As a racing fan, I didn't want to see him retire either, as each race has brought me joy and excitement beyond anything I could ever dream of.
‘I am undoubtedly his biggest fan. However, as his owner there are things to consider beyond just the joys of watching him race.
‘He has proven himself to be a great champion. Whether he is the greatest will be open to debate forever.
‘It is already a privilege to be mentioned in the same breath as legends such as Nijinsky, Sea Bird and Mill Reef. To me, he is of course the greatest ever - but I guess I might be a little biased.
‘Racing to us is only the first part of his career. Breeding is just as important, maybe even more.’
