O’Brien reaches 100 Royal Ascot winners with Gold Cup triumph

Aidan O’Brien’s 100th Royal Ascot winner came in the Gold Cup, but the bigger story was the balance of power at Ascot. Across Royal Ascot 2026, which ran from Tuesday 16 June to Saturday 20 June at Ascot Racecourse in Berkshire, Irish-bred runners and the sport’s biggest Group 1 yards set the tone, with the opening day featuring three Group 1 races and nearly 120 runners.

Scandinavia delivered the landmark on Wednesday 18 June, when Ryan Moore drove the colt past last year’s winner Trawlerman in the 2m4f Gold Cup. The victory gave O’Brien a record-extending 10th win in the race and made him the first trainer to reach 100 Royal Ascot winners. The King and Queen presented the trophy, and O’Brien was handed a celebratory saddle cloth to mark the milestone. Moore said Scandinavia “should have won easier” but that he had to work to get to Trawlerman, while O’Brien called the achievement “very special” and thanked everybody at Ballydoyle, including his wife Annemarie.

The numbers around O’Brien’s Ascot record only sharpen the scale of the feat. His first Royal Ascot winner was Harbour Master in the Coventry Stakes in 1997, and he had already moved past Sir Michael Stoute’s previous mark of 82 winners in 2023. Lester Piggott’s overall Royal Ascot record of 116 winners is now the next target, a figure that suddenly looks within reach for a stable that keeps finding new ways to dominate the meeting’s biggest races.

O’Brien’s week was not just about stamina. Mission Central’s King Charles III Stakes victory completed the full set of Royal Ascot Group 1s for O’Brien and Moore, a reminder that Ballydoyle’s influence stretches across every trip and division on the card. That breadth is what makes the 100-win mark feel larger than a lone milestone: it reflects a stable that keeps landing the defining races rather than collecting scattered prizes.

Night Of Thunder has been the other major force shaping the week. He sired three of the first four finishers in the Queen Anne Stakes, where 50-1 shot Ten Bob Tony beat More Thunder by half a length, with Opera Ballo third and Zeus Olympios fourth. By the end of day two, Night Of Thunder had sired three Group 1 winners in two days at Royal Ascot 2026, strengthening his case in the British and Irish champion sire battle after being crowned champion sire in both countries in 2025. For O’Brien, the headline was 100. For everyone else at Ascot, it was another reminder that the meeting still runs through Ballydoyle, elite sires and the horses that can turn a week into a dynasty.
