Sunday, June 14, 2026

Aidan O’Brien is on the verge of achieving 100 career winners at Royal Ascot, with several strong horses entered in key races like the Coventry Stakes and St James’s Palace Stakes. His continued success solidifies his position as the leading trainer at the event, where both he and regular jockey Ryan Moore are favored to claim top honors.

Aidan O’Brien is poised to reach a significant milestone at this year’s Royal Ascot, with the champion trainer sitting on 96 career winners at the prestigious event. As the meeting progresses, O’Brien aims to add to his tally with several strong contenders scheduled to run on Tuesday.

Among the leading horses are Confucius and Great Barrier Reef, both prominent in the betting for the Coventry Stakes, a key race for two-year-olds. Additionally, O’Brien’s Gstaad and Puerto Rico are considered front-runners in the St James’s Palace Stakes, a highlight event for three-year-olds over a mile.

Ryan Moore, frequently the rider for O’Brien’s horses, is currently favored to be the meeting’s top jockey, with odds of 1-3. Meanwhile, O’Brien himself is well positioned to claim the top trainer accolade, with odds at 1-5, reflecting his continued dominance at Royal Ascot.

The forthcoming races will be closely watched as O’Brien seeks to build on his already impressive record at one of British racing’s most significant fixtures.
