Royal Ascot 2026 belonged to one family. Anyone checking horse racing odds would have found race-by-race prices for the day’s meetings shifting fast as Ballydoyle and its closest rival took charge from the opening afternoon. By Saturday evening Aidan O’Brien had seven winners, a 14th leading trainer title, and a place in the record books as the first trainer in history to reach 100 Royal Ascot winners. His son Joseph finished second. Two yards, one family, the top two spots for the week.

Aidan’s century

O’Brien’s week was built on Group One results from the start. Mission Central opened his account in the King Charles III Stakes on day one, and Victorious followed in the Queen Mary Stakes to put Ballydoyle in control of the standings. Great Barrier Reef won the Coventry Stakes, Precise added the Coronation Stakes, Causeway took the King Edward VII Stakes on the penultimate afternoon, and Illinois rounded things off in a conditions race on the final card.

The moment that overshadowed everything came on day three. Scandinavia, ridden by Ryan Moore, hauled in Trawlerman inside the final furlong to win the Gold Cup and bring up O’Brien’s century of Royal Ascot winners, the first trainer ever to reach that mark. Anyone following the horse racing odds would have seen Scandinavia eased from 5-2 to 11-8 by the off, and the market had it right. He was a head in front at the line, and Trawlerman, the defending champion, had nothing left to give. The Gold Cup alone has now given O’Brien one in every 10 of his 100 winners at the meeting.

Beyond the seven victories, his runners added five placed efforts across the week, including Sun Goddess in second behind Liber Tango on the Friday card, with a further third to round off the tally.

Joseph pushes him closest

The nearest challenger to Aidan was his own son. Joseph O’Brien finished with five winners to take second in the trainer standings, giving Ireland a grip on both of the top positions that no rival yard could break.

Liber Tango and Limestone both won for the yard early in the week, and the 33-1 shot King Of Cloughan came home in the Windsor Castle Stakes to give Joseph a live presence in the standings from the off. He added two more before the festival was out to reach five, along with three seconds and a third across the five days.

“He’s a son of New Bay and all we can do is see how far he can climb, but he’s improved with every start,” O’Brien said about Limestone.

“He won the race at Navan that last year’s winner Carmers won. We knew he would stay well and I’m delighted for the team at home.”

One family, two yards

The final arithmetic was hard to argue with. Aidan leaves Ascot with 100 Royal Ascot winners and 14 leading trainer titles to his name. Joseph pushed him closer than any other trainer managed and came away with five wins of his own. For a week in June, the most famous meeting in British flat racing answered to one Irish family.

Donnacha O’Brien, Aidan’s other son, also fielded runners throughout the week, but left empty-handed.
