ALL 100 Aidan O’Brien Royal Ascot Winners Listed, as Scandinavia Brings Up Milestone With Gold Cup Win

Aidan O’Brien cemented his place as Royal Ascot’s most successful trainer on Thursday, 18 June 2026, when Scandinavia powered to victory in the Ascot Gold Cup under Ryan Moore, bringing up a remarkable century of winners at the Royal Meeting. The landmark success added yet another chapter to one of the greatest training records the sport has ever seen.

The Ballydoyle maestro arrived at Royal Ascot 2026 on 96 winners and edged closer to the milestone with victories on Tuesday from Great Barrier Reef in the Coventry Stakes and Mission Central in the King Charles III Stakes.

Then with Victorious landing Wednesday’s Queen Mary Stakes, this took Aidan O’Brien’s tally to 99 heading into Ladies’ Day on the Thursday.

With no winners in the early Thursday races on June 18, this left Scandinavia with the chance to make history in the meeting’s showpiece staying race,

And the St Leger winner duly delivered in gutsy fashion to see off the 2025 winner Trawlerman by a head under a power-packed Ryan Moore ride – giving O’Brien his 100th Royal Ascot success.

The Gold Cup win for Scandinavia gave Aidan O’Brien a record-extending tenth Ascot Gold Cup.

While the now retired Sir Michael Stoute is next best in the Royal Ascot winners list – with 82.

The achievement is all the more remarkable considering O’Brien’s first Royal Ascot winner came almost three decades ago.

That breakthrough arrived in 1997 when Harbour Master landed the Coventry Stakes, giving the then-emerging Irish trainer a first taste of success at the meeting that would become his own personal playground.

The Coventry Stakes has gone onto be O’Brien’s best Royal Ascot race – with 12 wins in total and winning the prize again in 2026 with Great Barrier Reef.

From there, the winners flowed. Giants of the turf such as Giant’s Causeway, Rock Of Gibraltar, Yeats, Duke Of Marmalade, Mastercraftsman, Minding, Churchill, Caravaggio, Paddington and Auguste Rodin all helped build the O’Brien legend at Ascot.

Few trainers have dominated so many different divisions, from precocious two-year-olds to Classic stars and elite stayers.

Among the most memorable of all were the great stayer Yeats, who won four consecutive Ascot Gold Cups between 2006 and 2009, and the brilliant Kyprios, who became another modern-day staying superstar for the yard with multiple Gold Cup victories of his own.

O’Brien’s influence on the meeting’s flagship staying race has been extraordinary, and Scandinavia’s triumph only strengthened that legacy.

Ryan Moore, O’Brien’s long-time ally in the saddle, was again at the heart of the story. The pair have enjoyed one of racing’s most successful trainer-jockey partnerships, combining for countless Group 1 victories around the world and many of those landmark Royal Ascot successes.

Moore’s cool, measured ride aboard Scandinavia ensured the milestone winner arrived on one of the meeting’s biggest stages.

Royal Ascot has always been regarded as the ultimate proving ground for the world’s best horses, trainers and jockeys, yet O’Brien has turned sustained excellence into an annual expectation.

From Harbour Master in 1997 to Scandinavia in the 2026 Gold Cup, the journey to 100 winners has featured some of the finest thoroughbreds of the modern era and further underlined Aidan O’Brien’s status as one of horse racing’s all-time greats.
