The Irish Champion Stakes: Europe’s Premier Middle-Distance Showdown
Held annually in September at Leopardstown Racecourse in Ireland, the Irish Champion Stakes has firmly established itself as one of the pinnacle events of the European Flat racing season 1. This prestigious Group 1 race headlines the opening day of “Irish Champions Weekend,” the biggest festival in Irish racing. Elite three-year-olds and older horses battle for supremacy over a testing 1 mile 2 furlongs (approximately 2012 meters) on turf, making it a true championship decider 3.
Its rich history began in 1976 as the “Joe McGrath Memorial Stakes.” Over the years, the race has evolved, not only determining the champion of Europe’s middle-distance division but also serving as the most crucial prep race for the highly anticipated Prix de l’Arc de Triomphe, drawing significant attention from racing professionals worldwide 1. The roll call of past winners reads like a who’s who of racing legends, including Sadler’s Wells (1984), Giant’s Causeway (2000), Sea The Stars (2009), and Golden Horn (2015). To claim victory here is often considered a testament to being the strongest horse of their era 1. Many champions, like Sea The Stars and Golden Horn, have used this race as a stepping stone to achieve the extraordinary feat of winning the Arc, further elevating its prestige and significance 2.
Beyond its strong ties to the Arc, the Irish Champion Stakes also acts as a vital global stepping stone to other major year-end races, including the British Champion Stakes, the Breeders’ Cup Turf in the United States, and even the Japan Cup and Hong Kong International Races 2. In recent years, legendary Irish trainer Aidan O’Brien has demonstrated unparalleled dominance, recording an astonishing 12 victories with horses under his care 2. As 2025 approaches, the global racing community eagerly awaits to see which connections will claim this coveted title and emerge as the dominant force of the autumn season.

Odds Analysis: Identifying Favorites and Value Bets
The odds comparison table above clearly illustrates how the market perceives the 2025 Irish Champion Stakes. The assessment of each horse is stratified into distinct tiers, each underpinned by specific justifications.
The Undisputed Favorite: Delacroix
All bookmakers unanimously position Delacroix as the overwhelming favorite 5. His odds are tightly clustered between 4/5 (1.8x) and 5/4 (2.25x), a testament to his strong performances, including a victory in the G1 Coral-Eclipse Stakes and a strong showing in the G1 International Stakes 9. Notably, his odds shortened dramatically from around 5/2 (3.5x) to their current level following news that another major contender, Ombudsman, would bypass this race 5. This indicates that the market has absorbed a significant portion of Ombudsman’s projected win probability into Delacroix, further cementing his perceived reliability. However, this also means the betting value is reduced. The initial strategic decision for punters will be whether to trust his proven ability at short odds or seek more lucrative alternatives.
Formidable Challengers: Shin Emperor, Anmaat, and Zahrann
Directly behind the favorite, a strong second tier has formed, comprising Shin Emperor, Anmaat, and Zahrann, whose odds range from 4/1 (5.0x) to 8/1 (9.0x) 5. This price band signifies that they are considered the most probable challengers to Delacroix’s dominance. However, there’s no clear consensus among bookmakers regarding their individual rankings within this group. Shin Emperor, with his impressive third-place finish in this race last year; Anmaat, a seasoned veteran with a stellar record; and Zahrann, a rapidly improving newcomer, each possess distinct strengths. The market is still deliberating which of these horses poses the greatest threat to Delacroix.
The Intriguing Dark Horse: White Birch
Slightly detached from the second tier, White Birch is valued at odds ranging from 8/1 (9.0x) to 12/1 (13.0x) 6. These odds reflect concerns about his absence from racing since May, yet this very factor could present an excellent “value bet” opportunity. White Birch is a known specialist on soft to heavy ground, and should the forecast rain materialize on race day, significantly altering the track conditions, his prospects would undoubtedly soar 15. The fact that some bookmakers maintained his odds even after the news of Ombudsman’s withdrawal suggests that the market may not have fully adjusted to the potential impact of track conditions. Considering this variable, his current odds might offer significant undervaluation compared to his proven ability in specific conditions.
Longshot Candidates: Royal Champion, Hotazhell, and Mount Kilimanjaro
The remaining contenders—Royal Champion, Hotazhell, and Mount Kilimanjaro—are all priced at 20/1 (21.0x) or higher, indicating a challenging assessment from the market 9. For any of these horses to secure a victory, they would require not only a subpar performance from the leading contenders but also a career-best effort themselves. Global bookmakers evidently consider such an outcome to be a remote possibility.
2025 Irish Champion Stakes: In-Depth Analysis of Key Contenders
While odds reflect market sentiment, a final assessment hinges on evaluating each horse’s raw ability, recent performance, and suitability for the conditions. Here, we delve into a detailed analysis of the main expected runners.
Delacroix – The Champion Elect
Aidan O’Brien’s three-year-old colt, Delacroix, boasts an official rating of 126, making him the highest-rated contender in this elite field 9. His season’s highlight was a gritty victory in the G1 Coral-Eclipse Stakes at Sandown, where he narrowly defeated a formidable opponent in Ombudsman by a neck, showcasing top-tier racing resolve 14. He followed this with a commendable second-place finish behind Ombudsman in the G1 International Stakes, reaffirming his class as one of the best of his generation 14. Earlier in the spring, he secured consecutive Group 3 wins at Leopardstown, indicating no concerns about his course suitability 14. His sole major defeat in the Epsom Derby can be attributed to the extended distance, as he has shown remarkable consistency over middle distances 14. Having suffered a defeat in a Group 2 race at this meeting as a two-year-old last year, this race presents an opportunity for redemption 9. Delacroix possesses all the credentials to justify his overwhelming favoritism and claim the champion’s crown.
Shin Emperor – Japan’s Hope for Redemption
Shin Emperor, trained by Japan’s Yoshito Yahagi, is a world-class impeccably bred colt, being the full brother to Arc winner Sottsass 16. His greatest asset is his proven track record in this very race, having finished an excellent third in last year’s Irish Champion Stakes. Despite encountering traffic issues in the straight, he ran a magnificent race, closing the gap significantly on the rapidly improving Economics and the previous year’s winner, Auguste Rodin 9. Jockey Ryusei Sakai commented after the race that Shin Emperor had “grown both physically and mentally” since last year, fueling expectations of an even stronger performance on a familiar stage 5. With a solid domestic record, including a second-place finish in the G1 Hopeful Stakes, he is certainly not out of his depth at this level 20. He returns fully prepared for “revenge” and to claim the title that eluded him last year.
Anmaat – The Veteran Challenger Against History
Owen Burrows’ seven-year-old gelding, Anmaat, is a seasoned and accomplished veteran with extensive experience 21. His career highlight was a victory in the G1 British Champion Stakes two years ago, underscoring his undeniable class 21. This season, he has shown no signs of decline at seven years old, recording consecutive second-place finishes in the G1 Prince of Wales’s Stakes and the G1 Tattersalls Gold Cup 21. His official rating of 123 is also a high figure, second only to Delacroix 9. However, Anmaat faces a significant historical hurdle: no seven-year-old has ever won the Irish Champion Stakes, and only one horse aged six or older (Swain in 1998) has claimed victory 9. The primary question is whether he can defy this exceptionally unfavorable statistic and etch his name into history.
Zahrann – The Rising Star
Trained by acclaimed Irish jockey-turned-trainer Johnny Murtagh, Zahrann is a three-year-old colt brimming with “unknown potential” 22. He made his debut this year, having not raced as a two-year-old, and has quickly risen through the ranks with a record of 2-1-1-2-1 22. His recent victory in the G3 Royal Whip Stakes, marking his first Group race success, confirms his genuine momentum 22. Trainer Murtagh holds Zahrann in high regard, comparing his raw talent to Sinndar, the legendary horse he rode to win both the Derby and the Arc 9. However, his past competition has not been at the Group 1 level, making his ability to handle this significant step up in class the crucial unknown factor. This rapidly improving young star certainly has the potential to ascend to the pinnacle in one swift leap.
White Birch – The Grey Assassin, Aided by the Ground
John Joseph Murphy’s five-year-old grey colt, White Birch, is renowned for his striking appearance and formidable performances on softer ground 23. His career-best effort came in last year’s G1 Tattersalls Gold Cup, where he powerfully overcame the eventual Arc winner, Auguste Rodin, on testing heavy ground 25. His connections intentionally curtailed his spring campaign early, specifically targeting the autumn season when softer ground conditions are more prevalent 15. Leopard
