Is it even a National Hunt race if Willie Mullins doesn’t dominate the top of the betting markets? In the case of the 2026 Irish Grand National, Argento Boy was the shortest-priced runner from Closutton and one of seven chances that Mullins has of winning the Fairyhouse showpiece for a third time.
His odds have drifted over the last couple of days, from single digits, and can now be had at as much as 18/1, alongside stablemate C’Est Ta Chance, with Kiss Will now Mullins’ shortest-priced runner.
Argento Boy has always had the right genes for this game. A grey gelding by Jukebox Jury (who also sired the race favourite, The Jukebox Kid), he is a half‑brother to Briar Hill, who ran away with the Weatherbys Champion Bumper at Cheltenham in 2013, so expectations were never going to be low.
He started to justify that faith in bumpers, bolting up on debut at Fairyhouse and earning himself a place in the 2024 Champion Bumper, where he finished midfield in what was, as usual, one of the deepest races of the season.
Chasing Transformation
The transformation really began once Argento Boy went chasing. After a season of hurdling, he found his feet over staying trips, winning a beginners’ chase at Punchestown over just shy of three miles on New Year’s Eve 2025.
If that Punchestown success was the hint, Naas in late January 2026 was the confirmation. Upped to an extended three miles on heavy ground and pitched into Grade 3 company, he knuckled down under Paul Townend to win the Finlay Ford At Naas Novice Chase, backing up the impression that stamina and a proper test over fences are his calling cards.
Patrick Mullins, acting as assistant trainer, put it neatly: “the trip and fences have been the making of him.”
Cheltenham Education and the Fairyhouse Test
From there, the Mullins team was bold enough to send Argento Boy to the Brown Advisory Novices’ Chase at Cheltenham, a Grade 1 over three miles that regularly exposes any weaknesses.
He finished eighth, not troubling the judge but “running a decent race” in top company, gaining the sort of hard schooling you cannot replicate on the gallops.
For a still‑raw staying novice, that kind of experience often pays off back at home when the emphasis switches from speed to stamina.
Fairyhouse over three miles and five furlongs is exactly that sort of different exam. The Irish Grand National is a relentless test of jumping, positioning, and deep reserves of energy, and Argento Boy’s profile fits very neatly with the type of horse that tends to go well in the race.
Irish Racing has already flagged him as one of the key horses to note, stressing that “the further he goes the better he’ll be,” which is precisely what you want to hear about a National candidate.
Ticking A Lot Of Boxes
There are a few key strands that make the case for taking Argento Boy seriously as a 2026 Irish Grand National contender.
First, there is his quietly efficient win record: two victories from four chasing starts is a solid way to get his jumps career going. He keeps finding enough, which is exactly the trait you want in a big handicap where races are often decided in the last 200 yards.
Then there is his ground and trip versatility within the staying bracket. He has won on yielding‑to‑soft at just under three miles and on heavy at just over three miles, and connections are adamant that extended distances bring out the best in him rather than exposing any stamina doubt.
Finally, the market appears to agree that he is a serious horse, and he has been trading among the leading contenders for Fairyhouse, as the title race between Gordon Elliott and Willie Mullins spills into Easter Monday. For a still‑lightly raced novice chaser, that is an encouraging sign rather than an overreaction.
Of course, this is the Irish Grand National, not a school sports day, and the case against Argento Boy has to be weighed too.
The most obvious concern is that he is still relatively inexperienced over fences. The race is a brutal test of jumping, with 24 fences to be met on the right stride.
Even Patrick Mullins has acknowledged that while the trip and obstacles have helped him, his jumping “still has room for improvement.” A single mistake early can leave you in the wrong place, using energy just to get back into contention.
Then there is the fact that his Cheltenham run, while respectable, showed he is not yet at the very top of the novice chasing tree.
Finishing eighth in the Brown Advisory suggests he belongs in Graded company but still has a bit to find if he is to become a dominant player, and Fairyhouse will not be any easier in terms of rough‑and‑tumble.
Weighing Up His Chances
Put it all together, and Argento Boy shapes as a thoroughly credible Irish Grand National candidate: a strong‑staying grey with good pedigree, a likeable win record, a recent Grade 3 success over three miles, a solid if unspectacular Cheltenham education, and crucially, a top team openly declaring Fairyhouse as his big target.
There are things to iron out, notably the odd untidy jump and the question of just how well‑in he is at the weights, but if you are looking for a horse on the upgrade rather than one whose best days are behind him, he ticks a lot of boxes for Easter Monday.
If he gets into a rhythm early, travels where his jockey wants him and sees out the marathon as strongly as connections believe he will, Argento Boy has every chance of making it three Irish Grand Nationals for Willie Mullins.
